If you are outputting an image from a DB blob field, then here's an example... // EMULATE DATA FROM THE DATABASE $type = 'image/png'; $comments = 'Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas porttitor congue massa. Fusce posuere, magna sed pulvinar ultricies, purus lectus malesuada libero, sit amet commodo magna eros quis urna.'; $image_data = file_get_contents('images/snowman.PNG'); // OUTPUT THE DATA echo "<div style='width:396;'> <img src='data:{$type};base64," . base64_encode( $image_data ) . "' width='394' height='393'> <p>$comments</p> "; RESULT3 points

Depending on what it is you're trying to do with the data, there are several ways to change a field. You can set up an accessor or mutator or use a query scope, for instance. Query scope sounds like what you're looking for, although should worse comes to worst you could just write a trait and use it on your model instances where needed.2 points

The PHP DateTime::diff() method provides a very convenient way of getting the days, hours, minutes and seconds components of a time difference so this script uses an AJAX request on loading to get the time remaining. From then on, it calls a javascript function every second to reduce the time displayed by one second. This greatly reduces network traffic and gives a consistent update performance. Repeatedly using AJAX could sometimes result in delays preventing a regular countdown interval. <?php ################################################################################################################## # # # THIS SECTION HANDLES THE AJAX REQUEST AND EXITS TO SEND RESPONSE (Days,hrs, mins, secs remaining) # # # if (isset($_GET['ajax'])) { if ($_GET['ajax'] == 'countdown') { $remain = ['days' => 0, 'hrs' => 0, 'mins' => 0, 'secs' => 0]; $dt1 = new DateTime( $_GET['target'] ); $dt2 = new DateTime('now'); if ($dt1 > $dt2) { $diff = $dt1->diff($dt2); $remain['days'] = $diff->days; $remain['hrs'] = $diff->h; $remain['mins'] = $diff->i; $remain['secs'] = $diff->s; } exit(json_encode($remain)); } } # # ################################################################################################################### $target = '2022-04-30 23:59:59'; // SET OR GET TARGET TIME HERE $targ = new DateTime($target); $target_time = $targ->format('g:ia'); $target_date = $targ->format('F jS Y'); ?> <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Countdown</title> <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script type='text/javascript'> var inter $().ready( function() { get_time_remaining() // call AJAX request to get remaining time inter = setInterval(countdown, 1000) // set timer to call "countdown()" function every second }) function countdown() { let s = parseInt($("#secs").html()) // get current time remaining let m = parseInt($("#mins").html()) let h = parseInt($("#hrs").html()) let d = parseInt($("#days").html()) if (d==0 && h==0 && m==0 && s==0) { // exit when target time is reached clearInterval(inter) $(".remain").css("background-color", "red") return } s--; // reduce display by 1 second if (s < 0) { s = 59; m-- } if (m < 0) { m = 59 h-- } if (h < 0) { h = 23 d-- } if (d < 0) { d = 0 } $("#days").html(d) // redisplay new values $("#hrs").html(h) $("#mins").html(m) $("#secs").html(s) } function get_time_remaining() { $.get( // make AJAX request "", {"ajax":"countdown", "target":$("#target").val()}, function(resp) { // put response values in display fields $("#days").html( resp.days ) $("#hrs").html( resp.hrs ) $("#mins").html( resp.mins ) $("#secs").html( resp.secs ) }, "JSON" ) } </script> <style type='text/css'> body { font-family: verdana, sans-serif; font-size: 11pt; } header { padding: 8px; text-align: center; width: 600px; margin: 20px auto; background-color: #F0F0F0; } .target { color: #006EFC; font-size: 16pt; } table { border-collapse: collapse; width: 400px; margin: 0 auto; } td, th { padding: 8px; text-align: center; width: 25%; } .remain { font-size: 24pt; color: white; background-color: black; border: 1px solid white; } </style> </head> <body> <header> <p>Countdown to</p> <p class='target'><?=$target_time?> on <?=$target_date?> </p> <!-- make target time available to javascript --> <input type='hidden' id='target' value='<?=$target?>' > <table border='0'> <tr><th>Days</th><th>Hours</th><th>Mins</th><th>Secs</th></tr> <tr> <td class='remain' id='days'>0</td> <td class='remain' id='hrs'>0</td> <td class='remain' id='mins'>0</td> <td class='remain' id='secs'>0</td> </tr> </table> </header> </body> </html>2 points

I don't have any specific recollection of such a thing, but a lot of things have changed in the css world, most notably the standardization of flexbox and grid that make older techniques and tricks of css layout obsolete. You just don't need those things anymore when flexbox or grid can take care of your layout needs with simple, consistent and easy to understand syntax. There was a time when you needed to know the ins and outs of floats and clear fix, and other arcane tricks of css, but that's basically obsolete knowledge. People also use to use tables inside tables inside tables to get their "pixel perfect" layouts, but that also has given way to a focus on creating layouts that adapt from desktop to mobile. This guy (Kevin Powell) has become well known in the css/web design world, and he really knows his stuff. This video covers flexbox. If you work through the examples with him, you will learn what you need. He also has a corresponding Grid video. If you want something more interactive, lots of people love Scrimba, and in particular Per Borgen, who is one of the Scrimba founders. He happens to have a free scrimba course covering grid and flexbox, so that is another way you can learn flexbox, if you want something more interactive. The free Scrimba Grid/Flexbox course is here: https://scrimba.com/learn/cssgrid2 points

PHPFreaks has been going through some ownership and hosting changes, and that has lead to some extended down time. The hosting for the site has been generously provided by a number of different people and organizations throughout the years, and without their patronage, phpfreaks would have shutdown many years ago. With that said, please understand that the volunteers who administer and moderate the site don't have control over the underlying infrastructure, other than what is provided to us. In this recent outage the new owner of the site, who supported it in the years following the sale of the original hosting company where phpfreaks was created, has provided us a lot of support and aid, and demonstrated a commitment to keep the site running for the foreseeable future. Unfortunately, with that said, there will probably be some additional outages in the near future as the server resources that run the site are being moved to a different co-location facility. Please bear with us through these difficulties, as we endeavor to keep the community alive and available for everyone who finds it useful. We will continue to keep doing the work to keep phpfreaks running, and we appreciate the many long time members who have made it their home.2 points

Apparently the DateInterval class supports milliseconds, but the default method does not support it as an input value. You need to instead use the createFromDateString class of that method // convert your date to DateTime object $date = '10:00:00.500000'; $dt = new DateTime($date); // convert your period to $interval = '00:25:10.300000'; //Extract time parts list($hours, $minutes, $totalSeconds) = explode(':', $interval); list($wholeSeconds, $milliSeconds) = explode('.', $totalSeconds); //Create interval with milliseconds $intervalString = "{$hours} hours + {$minutes} minutes + {$wholeSeconds} seconds + {$milliSeconds} microseconds"; $interval = DateInterval::createFromDateString($intervalString); // Add interval to date $dt->add($interval);// Format date as you needecho $dt->format('H:i:s'); echo $dt->format('Y-m-d\TH:i:s.u'); //Output: 2021-11-12T10:25:10.8000002 points

Just before closing the book on this one, please ask yourself this: In [another] four months time, are you going to look at this code and ask yourself "What the H*** does this do?"

First, let me just opine that there are generally accepted reasons to create stored procedures. Those include 'performance', 'adding business logic', 'doing things that can't easily be done in a single query/ie having procedural logic', 'providing a procedural api that enforces business rules', and in the case of triggers, enforcing complex data integrity, which is often done with triggers, and can't easily or robustly done client-side. What you have to understand about MySQL, is that it doesn't work the same way that Sybase/MS-SQL Server or Oracle work. In those DB's, sprocs are cached in global server memory, so they can be shared by connections. Oracle also has heavy client connection overhead. MySQL does not work that way. Quite probably, a normal query will be faster with MySQL in many circumstances, when compared with a sproc, because you have to understand that MySQL sprocs are not available in a shared memory structure like Oracle. So performance is not one of the advantages of sprocs in MySQL. The sproc memory exists PER Connection! So that should give you pause, from a performance standpoint, because each connection will need memory allocation for sprocs, and conversely, the fact that clientA is calling a sproc, does absolutely nothing for clientB. There has been rumblings that something might be done about this architecture, but as of MySQL 8, as far as I know the per connection sproc cache is still local. So to be absolutely clear, what happens when you create a connection to MySQL, every time you use a sproc, it gets compiled (if it was not already used), and stored in memory. There is not pre-compilation performance boost you get from other databases like Oracle. Furthermore, PHP is a "shared nothing" environment. Depending on how you are running PHP, database connections will be created/destroyed frequently, or upon every execution. The fact that mysql connections are lightweight and performant is one of the reasons it has always been a good partner for PHP data persistence. This was your original concern. Most of us tried to convince you that you already are covered for those concerns by: Disallowing multiple statements in PDO Using bind variables Using InnoDB with allocation of memory to buffer pools, to maximize cache hit of result set data PHP does give you a robust and highly capable language to build your reporting tool, and your code can be safe and will be performant against mysql, and sprocs bring nothing to the table that will make that better for you. I understand that you have felt frustrated in this conversation, but this is a frequent phenomenon in the tech communities I frequent, when someone comes from a point of view that has predetermined a particular approach is the only way to do it. People immediately question whether or not, as the old adage goes, this is a "person with a hammer, who sees everything as a nail." I think this was a valuable thread that contributed to the community, and I appreciate your perseverance and patience in sticking with it, but I also hope you can see that developers who are donating their time to try and help other developers tend to get a bit irritated when they perceive that someone is telling them "just shutup and answer my question", especially when they aren't convinced that the problem to be solved has been articulated clearly. With that said, I hope you will continue to find the forum valuable to you now and in the future.2 points

I was in my fifties when I first came across something called HTML. I knew Basic from from my days with a BBC home microcomputer so I started using Visual Basic to create web pages. Daily, I would log in to the Compuserve Bulletin Board using my dial-up modem to exchange ideas (much like now - plus ca change, plus ca meme). I started to write Java applets to enhance my pages but, no sooner had I started to become reasonably proficient, the world switched to Flash (which has since died a death). Disheartened, I let the Java lapse. One of the biggest mistakes I've made as today's phone apps are essentially Java applets. A year or so later I came across PHP and much prefered its Java/C type syntax to Basic. My preference was cemented when I discovered that rewriting my VB/ASP scripts in PHP gave me a 3x+ speed increase (in one case a 70x increase in performance as VB was crap at handling long string concatenations). Anyway, the moral is "You ain't too old".2 points

You've fixed things but you haven't fixed things. Like these: if(isset($_POST['d_name'])){ } if(isset($_POST['manner_death'])){ } if(isset($_POST['place_death'])){ } if(isset($_POST['nok'])){ } if(isset($_POST['rel_nok'])){ } if(isset($_POST['morgue_att'])){ } What are those doing? Nothing. They don't do anything. Then you have if(isset($_POST['tag_num'])){ if(isset($_POST['treatment'])) The first line makes sense, but the second? Without a pair of { } then it will only run the very first line of code that comes after: the assignment for $d_name. Then in your query, $query = "insert into data ( d_name, manner_death, place_death ,nok, rel_nok, morgue_att, tag_num, treatment) values ( '$d_name'.'$manner_death','$place_death','$nok','$rel_nok','$morgue_att','$tag_num','$treatment')"; you managed to fix the one syntax error but you created a new one. You cannot create websites by putting code in your editor and hoping everything will work. You have to make actual, conscious, deliberate decisions about the code. You have to know what different pieces of code mean. You have to understand why code is what it is and then how you can use it to accomplish what you want. So before you try to write more code, stop and take a few days to learn what you can about PHP. Then come back to this file and put some thought into each line of code in it.2 points

Let the users check the inventory with one form that queries the db and outputs a very simple screen that most easily can be done with an html table. Then give them a button that takes them to your 2nd form that lets them choose from a drop down of ages, and a dropdown of sex and updates the db with their choices. I assume that your db has one table that will have an age column and a sex column and the user id of any person who has made a commitment. Also you may have a table of those people who have committed that gives you contact info as well as the user id. So - 2 tables. Does this sound like something you can do?1 point

Perhaps something like this (my identifiers do not exactly match yours) SELECT h.schoolname as home , a.schoolname as away , sch.preview , GROUP_CONCAT(DISTINCT h.name, ', ', h.ht, ' ', h.pos, '; ', h.grade SEPARATOR ' / ' ) as home_team , GROUP_CONCAT(DISTINCT a.name, ', ', a.ht, ' ', a.pos, '; ', a.grade SEPARATOR ' / ' ) as away_team FROM schedule sch JOIN ( SELECT s.schoolname , concat(p.namefirst, ' ', p.namelast) as name , concat(p.feet, '\'', p.inches, '"') as ht , pos.description as pos , g.description as grade , s.school_id FROM school s JOIN player p ON s.school_id = p.schoolid JOIN grade g USING (grade) JOIN position pos USING (position) ) h ON sch.home_id = h.school_id JOIN ( SELECT s.schoolname , concat(p.namefirst, ' ', p.namelast) as name , concat(p.feet, '\'', p.inches, '"') as ht , pos.description as pos , g.description as grade , s.school_id FROM school s JOIN player p ON s.school_id = p.schoolid JOIN grade g USING (grade) JOIN position pos USING (position) ) a ON sch.away_id = a.school_id PS, output home: School 10 away: School 11 preview: Game on! home_team: Andrew Baker, 6'2" Point Guard; JR / Bernard Cook, 6'5" Shooting Guard; JR / Charles Draper, 6'1" Small Forward; JR / David Potter, 6'4" Power Forward; JR / Eric Fletcher, 6'0" Centre; JR away_team: Frank Gardener, 5'11" Point Guard; JR / Graham Hatter, 6'6" Shooting Guard; JR / Harry Joiner, 6'7" Small Forward; JR / Ian Miller, 6'4" Power Forward; JR / Julie Archer, 5'6" Centre; JR1 point

you should not put user-provided data into your sql query strigs. It exposes you to "SQLinjection". Used prepared statements intead https://www.php.net/manual/en/pdo.prepare.php https://www.php.net/manual/en/pdostatement.execute.php The first query "SELECT quantity FROM book ..." gets the quantity then stores that quantity in the variable "$available". If the book id isn't found, fetchColumn() would return "false" hence the intva()l to change that to 0 - if no books or no record I don't want to update).1 point

Agree, but it's pretty clear this is someone learning PHP who is perhaps doing coursework. Writing code of this sort would not be viewed kindly in any professional environment where there are code reviews.1 point

I see that you're using the parseInt function. What does it do?1 point

I'd do it this way $res = $db->query("SELECT status_to , COUNT(*) as tot FROM crm_log GROUP BY status_to "); $totals = array_column($res->fetchAll(), 'tot', 'status_to'); $heads = "<tr><th>" . join('</th><th>', array_keys($totals)) . "</th></tr>\n"; $vals = "<tr><td>" . join('</td><td>', $totals) . "</td></tr>\n"; ?> <table border='1'> <?=$heads?> <?=$vals?> </table>1 point

Remember, people are not there to see what is actually happening or what you are doing. The solution that you get that works might be something that you don't understand, but a person who helped you who put his or her time in should at least be thanked. At least you acknowledge and thanked that in the last post that you made. I once had someone help me with a PHP script that I didn't understand and even to this day still don't after deciphering it, but it worked and there wasn't another solution out there. So I used it anyways as I spent too much time on the particular part of the script. There are a lot of times I don't understand what something does, but only to have a light-bulb go on in my head months or even years later. Object-oriented programming is something that I could do, but really never understood the meat & potatoes of it until now. It's starting to make a lot of sense now and to me that is what is fun with it comes to coding.1 point

Greetings 🙂 This is a story up again. I think i have heard it before. Earning money, say good bye to all, and moving to the south or Asia (Australia is in oceania). First i moved to Hua Hin in Thailand, got married, divorced, moved to Torrevieja in Spain and then.... now i travel between Norway and Torrevieja while i am planing and opening a new page for making my new history for the future. I do not yet know what those plans are based on, or... i know what they are based on, but i dont know what the plans will be 👍 Soooo, what they will be when a finished result is in front of me. I dont have a clue. I just know that something is growing. I have studied what is applicable today within standards in development and programming. I feel as "lost and helpless" as almost a year ago when I resumed programming and development. It is not easy to get acquainted with the new when you have to learn the old that is basic again. Believe me, I've been trying for almost a year. Old age weighs, and age that is the one who should be so light and bear. I will never be the same 😞 Good luck mate 🙂1 point
