    People still use StackOverflow? That's only half a joke. Their community has always been toxic to newcomers and there's so much emphasis on correctness that anything less than perfect is unacceptable. And there's the hostility towards any form of discussion about what is right that I always mention when this subject comes up. SO is good when you're looking for a precise answer to a specific question, but it's terrible for actually asking the questions, or trying to weigh in as a new person with different answers. But I am glad they dethroned Expert Sex Change in search results. edit: If Your Common Sense/shrapnelcol came across this thread and decided they wanted to join our forum...

    A few notes about text bounding boxes which, I hope, will help in precise placement of your text. Suppose I have the text string "The lazy fox" which I want to display using 150pt Vivaldi . My image is 4896 x 3672 and I want the text placed at the bottom right but 250 pixels from the edges of the image. $box = imagettfbbox(150,0,'c:/windows/fonts/vivaldii.ttf','The lazy fox'); gives this array of coordinates of the four corners $box = Array ( [0] => 23 [1] => 55 [2] => 871 [3] => 55 [4] => 871 [5] => -140 [6] => 23 [7] => -140 ) You may wonder why it can't just give a rectangle from (0,0) to (width, height) to make sizing simple, but there is extra information to be extracted from the array Text width = (871 - 23) = 848 Text height = 55 - (-140) = 195 The baseline will be 140px from the top The text is offset 23 px to the right. My text, therefore, will be in a rectangle 848 x 195 positioned 250 px from right and bottom edges. The top left x coord of the rectangle will be (4896 - 250 - 848) = 3798 and top left y coord will be (3672 - 250 - 195) = 3227. However, to land the text precisely into this area we position it on the baseline and at the required x offset, ie (3798 - 23 , 3227 + 140) = (3775, 3367). I use a simple custom function to assist with this process function metrics($font, $fsize, $str) { $box = imagettfbbox($fsize, 0, $font, $str); $ht = abs($box[5] - $box[1]); $wd = abs($box[4] - $box[0]); $base = -$box[5]; $tx = -$box[0]; return [ 'width' => $wd, 'height' => $ht, 'ascent' => $base, 'offsetx' => $tx ]; } $box = metrics ('c:/windows/fonts/vivaldii.ttf', 150, 'The lazy fox'); $box = Array ( [width] => 848 [height] => 195 [ascent] => 140 [offsetx] => -23 )

    Don't use $GLOBALS. Forget it exists. There is never a good reason to use it. Pretend you never saw it.

    The code in each switch is identical so all it achieves is to ensure the calculation uses only the defined list of diameter options. Just use an array of the valid values to verify the values. You can use the same array to generate the option list <?php $diam_vals = [2,3,4,6,8,10,12,14,16,18,20,22,24,26]; $results = ''; if ($_SERVER['REQUEST_METHOD']=='POST') { $x = $_POST['x'] ?? 0; $y = $_POST['y'] ?? 0; $diametre = $_POST['diametre'] ?? 0; if ($x > 0 && $y > 0 && in_array($diametre, $diam_vals)) { $rayon = $diametre * 38.1; $dc = $x/2; $ad = ($y/2)-$rayon; $ac = sqrt(pow($ad,2) + pow($dc,2)); $ec = sqrt(pow($ac,2) - pow($rayon,2)); $LongueurBayonette = $ec*2; $alpha = asin($dc/$ac); $alpha = $alpha*180/M_PI; $beta = acos($rayon/$ac); $beta = $beta*180/M_PI; $angle = 180-$alpha-$beta; $results .= "X = " . $x . "mm" . "<br/>"; $results .= "Y = " . $y . "mm" . "<br/>"; $results .= "Longueur = " . number_format($LongueurBayonette,1) . " mm" . "<br/>"; $results .= "&beta; = " . number_format($angle,1) . "°" . "<br/>"; $results .= "Rayon = " . $rayon . " mm" . "<br/>"; $results .= "&phi; = " . $diametre . '"' . "<br/>"; } else { $results = 'Inputs are not valid'; } } ?> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Simplified Example</title> </head> <body> <form method="post" action=""> <fieldset> X: <input type="text" name="x" value="" /> <br/> Y: <input type="text" name="y" value="" /> <br/> Diametre: <select name="diametre"> <option value="0"> </option> <?php foreach ($diam_vals as $d) { echo "<option value='$d'>$d</option>\n" ; } ?> </select> <input type="submit" value = "Calculer" /> </fieldset> </form> <br> <?=$results?> Just curious - do you have a diagram of how those values relate to one another. It metions "rayon" and "bayonnette" so my guess is that it is some kind of laser rifle with attached bayonet (but I could be wrong) 😊

    I have to agree - do a single query to get the events for the month.

    I can't imagine a scenario where the gobbledy-gook of a system you apparently are trying to create would be justified, or possible within your demonstrated engineering capabilities. You are talking about trying to create a system that requires a user to only use one workstation and browser to access your system. I don't know what your system would be doing, but it better be providing literally life saving services, because short of that, nobody is going to put up with the restrictions you have in mind. They are anti-user, and when you make things difficult for users, they stop using your system, or never even stay long enough to pass the entry point. It is damn difficult to get anyone to sign up to use legitimately valuable services, which is why you see so many systems that integrate with facebook, google and twitter, so that you can create your account and trust authentication from those systems to allow access. Furthermore some of your plans reflect an apparent lack of understanding of Internet basics like NAT. In your system, if we were to follow along with your plans, for a large company with perhaps 1000 employees at a particular site, you plan to only allow 1 employee there to use your system. Ditto universities, or even an average household: "Hey there roommate, I just made an account at this site, you should too!" "WTF, the system says I'm banned!" Since you are focused on investigating a client IP, I will say this about IP addresses -- they are reliable at least to the degree that they reflect the tcp socket connection from the client to the server. That information bubbles up to PHP from the IP layer, to the server, and finally to PHP's $_SERVER superglob. The problem is, that a client could have bounced through a variety of gateways, proxy servers or VPN prior to the point that you are finally connected. In many sophisticated hosting environments there are things like load balancers or reverse proxy servers that sit between the client connection and the server which interfere with $_SERVER['REMOTE_ADDR']. Rather than see the client IP, you instead see the IP of the proxy server. If you have that sort of environment, then you can examine $_SERVER['X-Forwarded-For'] or $_SERVER['HTTP_X_FORWARDED_FOR'] variables. These may be arrays with a series of addresses. Again you have the issue that these are provided by the "client" so if it is a proxy server you can depend on at least the most recent address to have been the one that made the TCP socket connection to YOUR proxy server. Other legitimate proxy servers will provide the same data. However, someone who is taking steps to hide their origin is not going to be prevented from obscuring their IP and there is absolutely nothing you can do about it. Almost everyone uses NAT in some form, so the actual person IP address of a workstation on a network is never going to be visible (and would also be useless if it was, since these will be non-routable IP addresses that are shared by hundreds of millions of users). Solutions to the issue of certification and authentication, when people have real and legitimate reasons to solve them, involve cryptography. What you are trying to do can be accomplished using X.509 certificates which have support built into browsers. In a nutshell, at account creation time you would generate an client certificate for that user, installing that into your server, and then providing the signed cert back to them in a specific header (application/x-x509-user-cert ). This will cause the browser to prompt the user to install the cert into their browser. If they accept you know have a reliable way of identifying a specific user. At that point, whenever they connect (must be under SSL) you'll be able to authenticate them back to your system via that particular certificate. Those without a client certificate will be unable to connect. You can think of this as white listing. It is highly effective but is typically used only in environments where the system knows in advance who their allowed users are. Trying to use it in a public facing website with an unknown user base is something you just don't see because the benefits of trying to do this far outweigh the tolerance that people have for a system that has that degree of odious overhead and invasion of their privacy. In conclusion: The types of things you are obsessed with are all edge case items. No quality system begins with the premise that the #1 goal is to try and catch and outsmart an imaginary horde of people attacking your site for reasons unknown. This started as a specific thread about the contents of $_SERVER variables and then escalated into fairly delusional territory, with a dash of your personal Devshed drama thrown in. And let's just be clear about one thing: If you ever bring up your personal issues regarding your Devshed access again, which are irrelevant to this community, then your access to this community will end as well. It's off topic, it's a waste of people's time and efforts here, and it's rude. I just want to be clear that I won't tolerate it again.

    If it helps, note that that a <button> element can have a value attribute independent of its label <?php $option = $_GET['option'] ?? ''; if ($option) echo "You chose $option<hr>"; ?> <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Sample</title> </head> <body> <form> Select an option <button name="option" value="1">Choose me</button> <button name="option" value="2">Choose me</button> <button name="option" value="3">No, Choose me</button> <button name="option" value="4">No, Choose me</button> <button name="option" value="5">No, Choose me</button> </form> </body> </html>

    code that unconditionally (always) outputs the raw database statement errors for the connection, query, prepare, and execute statements, only helps hackers when they intentionally trigger errors, since these errors contain things like the database hostname/ip address, database username, if a password is being used or not, part of the sql syntax, and web server path information. the only time you should output the raw database statement errors is when learning, developing, or debugging code/query(ies) and you are viewing the site as the developer/programmer. at all other times, you should log these errors. the simple way of doing this is to use exceptions for errors and in most cases let php catch and handle the exception, where php will use its error related settings to control what happens with the actual error information (database statement errors will 'automatically' get displayed/logged the same as php errors.) you would then remove any discrete error handling logic, since it doesn't add any value for a legitimate visitor to your site, and it will no longer get executed when there is an error (execution transfers to the nearest exception handler for the type of exception or to php if there is none.) the line that Barand posted enables exceptions for errors for the mysqli extension.

    $q = 'SELECT ID FROM table'; That is a SQL query. You have to run that query through your database, receive the results, and then look for each single matching image in the directory for every returned record. You can probably skip looking in the directory, though. It will only tell you if the file exists. So if you already know (or assume) the file exists then you don't need to bother looking.

    Defining a value in the parameter list makes that parameter optional. If it's not provided when the function is called, the it takes on the value assigned to it. Your specific example doesn't really make use of the feature effectively. Take something like this for example though: function findFiles($directory, $includeHidden = false){ $iter = new DirectoryIterator($directory); $list = []; foreach ($iter as $item){ if ($item->isFile()){ $isHidden = $item->getFilename()[0] === '.'; if ($includeHidden || !$isHidden){ $list[] = $item->getPathname(); } } } return $list; } That function requires at least one parameter when it's called, the directory to search. So you end up with the following options for calling it $files = findFiles('/home/kicken'); /* executes with $directory = '/home/kicken', $includeHidden = false */ $files = findFiles('/home/aoeex', true); /* executes with $directory = '/home/aoeex', $includeHidden = true */

    Your randomNr array contains 10 elements so foreach($randomNr as $number) will give 10 columns. You need to pick a random 6 numbers out of the 10. Separate the php code from the html. Use CSS for styling the output. Example <?php $randomNr = range(0,9); $bingokaart = display($randomNr); function display ($arr) { $result = ""; for ($row = 1; $row < 7; ++$row) { $rand6 = array_rand($arr, 6); $result .= '<tr>'; foreach ($rand6 as $n) { $result .= "<td>$row$arr[$n]</td>"; } $result .= "</tr>\n"; } return $result; } ?> <!DOCTYPE html> <html> <head> <title>Sample</title> <style type="text/css"> table { border-collapse: collapse; } td { padding: 2px; } </style> </head> <body> <table border='1'> <?= $bingokaart ?> </table> </body> </html>

    I totally agree with @requinix regarding the two tables. However, if you are willing to compromise over the output, you could do something like this SELECT uid , name , SUM(CASE payment_type WHEN 'cash' THEN payment ELSE 0 END) as cash , SUM(CASE payment_type WHEN 'card' THEN payment ELSE 0 END) as card , cost , cost-SUM(payment) as balance FROM payment GROUP BY uid +------+------+------+------+------+---------+ | uid | name | cash | card | cost | balance | +------+------+------+------+------+---------+ | 1 | kim | 0 | 100 | 100 | 0 | | 2 | lee | 95 | 0 | 95 | 0 | | 3 | kent | 50 | 50 | 100 | 0 | | 4 | iya | 40 | 20 | 80 | 20 | +------+------+------+------+------+---------+ If you really need every transaction listed, the SQL becomes quite complex involving user variables and subqueries. It would be much easier to do in the PHP as you output each row. [EDIT] ... For the sake of completeness SELECT uid , name , cash , card , cost , cost-total as balance FROM ( SELECT name , CASE payment_type WHEN 'cash' THEN payment ELSE 0 END as cash , CASE payment_type WHEN 'card' THEN payment ELSE 0 END as card , cost , @tot := CASE @previd WHEN uid THEN @tot + payment ELSE payment END as total , @previd := uid as uid FROM ( SELECT * FROM payment ORDER BY uid ) sorted JOIN (SELECT @previd:=0, @tot:=0) initialize ) recs; +------+------+------+------+------+---------+ | uid | name | cash | card | cost | balance | +------+------+------+------+------+---------+ | 1 | kim | 0 | 100 | 100 | 0 | | 2 | lee | 95 | 0 | 95 | 0 | | 3 | kent | 50 | 0 | 100 | 50 | | 3 | kent | 0 | 50 | 100 | 0 | | 4 | iya | 40 | 0 | 80 | 40 | | 4 | iya | 0 | 20 | 80 | 20 | +------+------+------+------+------+---------+

    Don't do that. Not in the actual table at least. Some people recommend this stupidity to try and avoid name collisions in their queries (such as two tables have a Label column) but such issues can be easily handled using the table.column syntax in your query rather than cluttering up column names in the table. SELECT o.Label as o_label, s.Label as s_label FROM order o INNER JOIN status s ON s.Id=o.Status One of the applications I work on was original designed using a scheme like that where every column has a table specific prefix to it and it's super annoying (long names, broken autocomplete) for no real benefit. I've been slowly undoing that when I can and just giving the columns nice simple names. I'd also suggest just using the full table name in your constraint names rather than some alias. It makes things very clear when someone 6 months later needs to decipher things.

    Yes but you don't want to run both at the same time. If you really wanted to, you would need to change the Apache port on one of them as they both use port 80

    Protecting a form field from what? htmlspecialchars() is for use when outputting user-supplied data data to a web page. mysql_real_escape string() is was used to protect input values to queries from SQL injection. This is now obsolete, replaced by mysqli_real_escape_string() or (better still) the use of prepared statements to completely separate the query code from the user-supplied data.

    the path being used in the opendir() statement either has a hard-coded '/home/sites/' in it or is using a variable that has that incorrect value in it. based on the path where the code is actually at, that part of the path should be - /home/customer/www/

    I have been playing around with a possible database solution to your problem Given that a postcode such as "EH12 3AB" breaks down into four parts viz +------+----------+--------+------+ | area | district | sector | unit | +------+----------+--------+------+ | EH | 12 | 3 | AB | +------+----------+--------+------+ ...

    If this is a repetitive project that is going to build all of the mentioned arrays every time it is executed, perhaps you should consider not having to re-build your second array by using the SKU as the index value of the first array and avoid creating the 2nd array. Change this: $product_table[] = ['SKU' => $sku, 'Label' => $attribute_name, 'Value' => $term_obj->name ]; to: $product_table[$sku][] = ['Label' => $attribute_name, 'Value' => $term_obj->name ];

    here's a list of things i saw in the posted code - 1. don't put php variables inside of double-quotes if they are the only thing in the string. 2, don't use or die() for error handling. use exceptions and in most cases let php catch the exception. note: your use of mysqli_error(...) in the connection code won't work because there's no connection to use. 3. don't unconditionally output database errors onto a web page (this will go away when you get rid of the or die() logic.) 4. don't run queries inside of loops. learn to do JOIN queries. 5. if your code is tabbed that far over because it is located inside your html document, you need to put the php code that's responsible for getting/producing data before the start of your html document, fetch the data into appropriately named php variable(s), then use those variable(s) in the html document. 6. handling the negative/failure case is usually shorter then the positive/successful case. if you invert the logic tests and handle the negative/failure condition first, your code will be clearer. you won't have logic for the negative/failure case 10's/100's of lines later in the code. 7. don't use loops to fetch what will be at most one row of data. just directly fetch the single row of data. 8. don't put static calculations inside of loops. the various date values shouldn't change during one report (where they are at now, they will if the request spans midnight.) put them before the start of the loop. 9. don't put quotes around numbers. 10. don't selected things that are not used and don't create variables that are not used (given the amount of code, the cases i saw of this may not be accurate.) 11. if you are looping to do something (should go away with JOINed queries), don't evaluate count() statements in the loop. determine the loop count, once, before the start of the loop. 12. doing some of these things will simplify variable naming. you won't have to think up unique names for variables because you will only have one instance in the code. 13. the $AffID is probably from external/unknown data. you should NOT put eternal/unknown data directly into an sql query statement. use a prepared query, with a place-holder for each data value, then supply the data when the query gets executed. switching to the much simpler php PDO extension will make using prepared queries easy compared to the php mysqli extension.

    You could assign the event names to an array, for example: $name = array(); while ($row_events = $sth_events->fetch(PDO::FETCH_ASSOC)) { $name[] = $row_events['name']; } Then you could use implode() to output the array. Note that I streamlined the following code a bit: $week .= '<td><div class="'; $week .= ($today == $date) ? 'today' : 'day'; $week .= '">' . $day . '</div>' . implode('<br>', $name) . '</td>'; With that said, it would be better to rewrite the script, as requinix is suggesting, so that you're not running queries inside of loops.

    I've been wrestling with this logic puzzle for days... My website lists item prices as they are posted: First item: item# ABC1234 = Hammer $5.00 Visitor then submits (to the same page) more item numbers (e.g. item# DEF9999) and the displayed list will grow: item# ABC1234 = Hammer $5.00 item# DEF9999 = Crowbar $6.00 --------------------------------------- However, when website gets visited via Affiliate, I want PHP to launch a Session to "remember" the First Referred Item, along with the Affiliate: // http://www.example.com/salePrice.php?Affiliate=SomeExampleCompany&item=ABC1234 <?php if(isset($_GET["Affiliate"])) { session_start(); $_SESSION["Affiliate"] = sanitized($_REQUEST["Affiliate"]); $_SESSION["item"] = sanitized($_REQUEST["item"]); } ?> <body> <form action="salePrice.php" method="post"> etc. etc. etc. The problem: Session won't stay running if visitor subsequently posts more items to the same page. (I thought once a Session starts, the Session will run as long as you don't navigate away from the page.) Without having to put "session_start()" on the top of the page (and have Sessions running no matter what), what is the trick to get this to work?

    OR if you use the same named hidden field for all the forms, 'action' for example, each with a unique value, you can eliminate any isset() tests for that field since it will be set if the request method is post.

    So we all (most of us) know some CSS. You might not consider yourself a web designer, be fluent with all the popular libraries, but you know your way around how to do it. Like if you want to make something bold you could inline it <span style="font-weight:bold;">An important statement</span> but you're smarter and you know you should .bold { font-weight: bold; } <span class="bold">An important statement</span> A trivial example, of course, but it demonstrates how you should use CSS. Right? No. God damn *#(*^y$&#ing NO. So maybe it's a bad example. People don't actually do that. Okay. Let's look at some official Bootstrap examples instead. <button type="button" class="btn btn-lg btn-default">Default</button> No. <table class="table table-striped"> Stop that. <ul class="list-group"> <li class="list-group-item">Cras justo odio</li> Dude. What's the problem here? You're restating the obvious! I know that button is a button. It's got #*^(ing "button" right in the (*^-@$ markup. Ooh, it's a LARGE button. Wow! And hey, that table has stripes? Amazing! And you mean to tell me that UL is a list and the LI is an item? You're blowing my mind! You're also DOING IT WRONG. The power behind CSS is (a) not having to tell the browser that yes, in fact, that button really is a button, and (b) not having to say the same thing over and over again in different places. And that is where Bootstrap fails miserably. You want to create a button? Go ahead. Create the button. Then throw a few classes at it so it looks the way you want. Want another button? Create another button and throw classes at that one too. Created a button and it doesn't look right? Oh damn, you forgot one of the classes you have to include. Ha ha, oops. "But that's how CSS should be used!" No. You're all missing the (*@#*^ing point and making everything hard on yourself and the people who have to deal with your crap. What if I want to add a dropdown list of items? What should I do? The page already has a couple dropdowns on it so I know the styling is in place. I'll add a simple <select> and... nope, looks like a plain list. No styling applied. What happened? What happened is that I didn't apply the handful of classes necessary to make the list appear like the damn list it should already be. What happened is that I forgot I have to add in the presentation aspects to my HTML. And that's what this whole stupid thing boils down to: people can't shift their mindset away from the presentation, and while they know not to mix presentation with markup they've not noticed that all they did was trade one syntax for another. The problem is still (@^$ there. "Oh, right, yeah, if you're so smart then how would you do it?" Thank you for asking. You want a button. You want a large button. You want a large button that draws peoples' eyes to it because it's the button they probably want to use and so it's the default. That's presentation. Forget about presentation. You want a default button. That's it. That's all you should have to care about. <button type="button" class="default">Default</button> Done. "But no, it doesn't look the way I want!" I don't give a damn how you want it to look. I want to know what the button means. What is the significance behind the button. What does it represent. Because ultimately that's what the HTML markup needs to concern itself with. Write semantic markup and leave out the presentation crap because it has no place in the document. "Oh, so you think we shouldn't have any CSS at all or what?" Take those words out of my mouth before I cram them back down yours. button { /* make it look like a nice button */ } button.default { /* blue or whatever */ } There. Now the presentation is accounted for in the @(!^)$ place where it should be: CSS. And if I want to add another default button somewhere I don't have to look up the Bootstrap reference because I don't remember which 5 classes are relevant. Default button? Default button. The only way this could improve is if HTML added a way to actually identify the default button of a form, in which case that class=default goes right out the damn window and the CSS targets that new attribute or whatever it is instead. "Noo, it's not a large button!" Alright. Fine. Let me take a deep breath before I have to deal with you. So. Why do you want it to be large? Don't give me some stupid reason like "because I want it to be large". What is the reason behind making it large? What decision process did you go through in your head that resulted in the button needing to be larger? Why is the normal size for buttons not appropriate? Maybe the form is a modal and you want larger buttons? Okay. Did you mark the form as modal? Because that's the first thing you have to do. <form class="modal"> form.modal button { /* larger */ } And done. Problem solved. Problem solved in a way that keeps the appearance of the button separate from the markup of the button. Want to add another button to the modal? Go on. Add another stupid button. One that doesn't require any classes just because it's supposed to be larger. What you might be able to realize here is that now I've established a rule saying "buttons in modal forms are larger". And it applies everywhere you have a modal form. If you make another modal form then magically the buttons are larger there too! And without having to find that first place you had that one modal form, what page was that again, oh right, over here, now what classes and CSS files did I have to use for it to make it look that way, oh right, those classes. How about a striped table? Why is it striped? Because it's a table that will grow vertically and has enough data in its columns that people need help scanning through them? So what you're telling me is that the table is, say, "dense"? <table class="dense"> table.dense > tbody > tr:nth-child(odd) { /* striped */ } Somehow I'm able to rub a couple brain cells together and end up with a way of identifying the table for what it is and not what I want it to look like on the page. How about a regular list? Nothing special? <ul> <li>Cras justo odio</li> Nothing (*&^!@ special. Now when I come along, I can write markup into your fancy page you spent a couple days tweaking until it looked oh so pretty, and I don't have to run off to the kitchen where I can cool my heels instead of planning your "accidental" death because I can write simple, logical, and minimal HTML that represents what I'm adding without having to fire up five different browsers to see that I got all the required classes. What's more, if someone decides that modal dialogs on mobile devices need to look a little different, I don't have to spend a day searching the codebase for anything modal because the work has gone from "go fix all the modal dialogs to use this new CSS class someone wrote" to "apply media queries to adjust the existing modal dialog to better suit mobile screens". This isn't damn rocket science. I know you web designers had a hard time in college with your liberal arts degree and that's it's so unfair you have to work with computer graphics instead of living in a loft painting bowls of fruit all day, but surely even you are smart enough to understand these principles. Stop thinking with your eyes and start thinking with your brain. And now I go back to work. Dealing with stupid crap. That I put off by ranting about it here.

    use array_filter() with the ARRAY_FILTER_USE_KEY flag set. EDIT: Of course the easiest method is not to put data into the array that you then want to remove PS If you prefer to use a foreach loop then $result = []; foreach ($array as $k => $v) { if ($k) { $result[$k] = $v; } }

    As you are sorting on "name", which is the first element of the sub-arrays, you can just use an ordinay sort() or rsort() call. (By default it will sort on the values oof the first element) EG $tadminlist["pvp"] = [ [ 'name' => 'mapname1', 'type' => 'pvp', 'beta' => 'y', 'final' => 'n', 'modded' => '', 'classification' => 'land', 'sf' => 'n', 'tod' => 'dawn', 'weather' => 'fog', 'es2' => 'y' ], [ 'name' => 'mapname3', 'type' => 'pvp', 'beta' => 'yy', 'final' => 'n', 'modded' => 'y', 'classification' => 'air', 'sf' => 'y', 'tod' => 'day', 'weather' => 'rain', 'es2' => 'n' ], [ 'name' => 'mapname2', 'type' => 'pvp', 'beta' => 'n', 'final' => 'y', 'modded' => 'n', 'classification' => 'sea', 'sf' => 'n', 'tod' => 'night', 'weather' => 'clear', 'es2' => 'n' ], ]; echo "line = " . join(', ', array_keys($tadminlist["pvp"][0])) . '<br><br>'; listData($tadminlist["pvp"]); echo "<br>SORTED ASC<br>"; sort($tadminlist["pvp"]); listData($tadminlist["pvp"]); echo "<br>SORTED DESC<br>"; rsort($tadminlist["pvp"]); listData($tadminlist["pvp"]); function listData($arr) { foreach ($arr as $tlist) echo join(', ', $tlist) . '<br>'; } OUTPUTS line = name, type, beta, final, modded, classification, sf, tod, weather, es2 mapname1, pvp, y, n, , land, n, dawn, fog, y mapname3, pvp, yy, n, y, air, y, day, rain, n mapname2, pvp, n, y, n, sea, n, night, clear, n SORTED ASC mapname1, pvp, y, n, , land, n, dawn, fog, y mapname2, pvp, n, y, n, sea, n, night, clear, n mapname3, pvp, yy, n, y, air, y, day, rain, n SORTED DESC mapname3, pvp, yy, n, y, air, y, day, rain, n mapname2, pvp, n, y, n, sea, n, night, clear, n mapname1, pvp, y, n, , land, n, dawn, fog, y To sort by any other element would require usort, eg to sort by classification usort($tadminlist["pvp"], function($a, $b) { return $a['classification'] <=> $b['classification']; } );

    Applying opacity to a div affects everything within the div, including type and nested divs. Use background opacity via rgba() to do what you're wanting: body{ background: url("https://image.ibb.co/h93Ndo/abstract.jpg") top right no-repeat; background-attachment: fixed; } .body-container{ display: flex; flex-direction: column; justify-content: stretch; align-items: stretch; background: red; color: white; min-height: 100vh; } .header{ flex-grow: 0; background: rgba(58, 152, 253, 1); } .two-cols{ flex-grow: 1; display: flex; flex-direction: row; justify-content: stretch; } .left-container{ display: flex; flex-direction: column; justify-content: flex-start; flex-grow: 1; flex-basis: 20%; background: rgba(59, 74, 83, 1); } .content{ display: flex; flex-direction: column; justify-content: flex-end; flex-grow: 1; flex-basis: 80%; background: rgba(255, 255, 255, .7); } Also, is there any reason why you needed to add the !important to the display rule on the .body-container div? @gizmola - apparently I'm going to need to read that article as well as I've not found float collapse to be an issue using flexbox. Or at least I've not recognized that that's what it is... Anyway - thanks for the link!

    1) set php's error_reporting to E_ALL. it is not set to report exceptions and fatal runtime errors, you won't see anything for these type of errors. 2) on the old machine, what 'engine' were the tables using, InnoDB or MyISAM? if they were using MyISAM, then the various commit statements where having no affect and the queries were being executed in the order they are in the php code. 3) the usage of the various commit statements are causing the INSERT and UPDATE queries to not actually be executed until you call the ->commit() method. for prepared queries, i don't know what value the ->execute() calls return for INSERT/UPDATE queries since they are actually being executed later. 4) for the SELECT/INSERT/UPDATE queries for the vis_mistakes table. you can use one INSERT ... ON DUPLICATE KEY UPDATE ... query. if this is the reason you think you need to use the various commit statements, eliminate them and use this one query. 5) the 'output' you have posted doesn't seem to exactly match the posted code and it includes the UPDATE mysessda ... sql which should not be output if the code is really stopping, skipping conditional logic, or transferring execution to any exception handler/php. 6) speaking of an exception handler, since your code is throwing its own exceptions, do you have a custom exception handler and if so, what does it do for exception types that it does not handle, such as mysqli exceptions?

    Take a look at these two lines of code $row = mysqli_fetch_assoc($result); while($row = mysqli_fetch_assoc($result)){ and tell your rubber duck what they are doing.

    I'd go a step further and give all the checkboxes the same name EG name='problem[]' so they are posted as an array <label><input type="checkbox" name="problem[]" value="Hard Drive Crashed"> Hard Drive Crashed</label><br> <label><input type="checkbox" name="problem[]" value="Has Virus"> Has Virus</label><br> <label><input type="checkbox" name="problem[]" value="Needs Operating System"> Needs Operating System</label><br> <label><input type="checkbox" name="problem[]" value="Needs Microsoft Office"> Needs Microsoft Office</label><br> <label><input type="checkbox" name="problem[]" value="Interested In Backup Services"> Interested In Backup Services</label><br> <label><input type="checkbox" name="problem[]" value="Wants A Custom PC Build"> Wants A Custom PC Build</label><br> In your processing foreach ($_POST['problem'] as $problem) { echo $problem . '<br>'; }

    I found it here Or did you have something more like this in mind? Save this code as "stave.svg" <svg width="1000" height="200" viewBox="0 0 1000 200"> <defs> <style type="text/css"> .trebleclef { fill: black; font-size: 50pt; } .bassclef { fill: black; font-size: 40pt; } .curly { fill: black; stroke: none; font-size: 110pt; font-weight: 100; } .stave { stroke-width: 1px; stroke: gray; fill: none; } </style> </defs> <!-- treble --> <line x1='40' y1='30' x2='960' y2='30' class='stave' /> <line x1='40' y1='38' x2='960' y2='38' class='stave' /> <line x1='40' y1='46' x2='960' y2='46' class='stave' /> <line x1='40' y1='54' x2='960' y2='54' class='stave' /> <line x1='40' y1='62' x2='960' y2='62' class='stave' /> <text x='44' y='65' class='trebleclef'>&#x1D11E;</text> <!-- bass --> <line x1='40' y1='130' x2='960' y2='130' class='stave' /> <line x1='40' y1='138' x2='960' y2='138' class='stave' /> <line x1='40' y1='146' x2='960' y2='146' class='stave' /> <line x1='40' y1='154' x2='960' y2='154' class='stave' /> <line x1='40' y1='162' x2='960' y2='162' class='stave' /> <text x='44' y='165' class='bassclef'>&#x1D122;</text> <!-- stave ends --> <text x='-20' y='132' class='curly'>{</text> <path d="M 40 30 L 40 162" class='stave' /> <path d="M 960 30 L 960 162" class='stave' /> </svg> Then, in your html <div><?php include 'stave.svg'?></div> <div><?php include 'stave.svg'?></div> <div><?php include 'stave.svg'?></div> Which should give you
