PHP close loop outside if function

amirelgohary1990 posted a topic in PHP Coding Help

Hello I need to find a way to close loop outside if condition like below example if(escape($_POST['jobCategory']) != "all-categories" && escape($_POST['countryId']) == "all-countries"): $query = mysqli_query($dbConnection,"SELECT jobs.id, jobs.job_title, jobs.salary, jobs.employer_id, employers.employer_name, employers.employer_logo FROM jobs LEFT JOIN employers ON jobs.employer_id = employers.employer_id WHERE job_status = '".mysqli_real_escape_string($dbConnection,'Active')."' AND id IN (".mysqli_real_escape_string($dbConnection,$job_id_imploded).") "); while($row = mysqli_fetch_assoc($query)){ // Start Loop $job_id = $row['id']; $job_title = $row['job_title']; endif; <div class="job-title"> <a href="job_post.php?job_id=<?php echo htmlspecialchars($job_id) ?>" class="job-title-link"><?php echo htmlspecialchars($job_title); ?></a> </div> } // End Of Loop Gives me error HTTP ERROR 500

Get Image by number, but if loop when no image? Help

Rowena_Harris posted a topic in PHP Coding Help

Hi - can anyone help? I'm new to PHP land, and failing at this particular part. I have an image slider - where each image is contained in a div (e.g it is not a slider using ul and il...) It is will be used in a template for many pages, which will each have a varying number of images. There for I need to create a loop that say 'when there is no img url found, return to img 1' I'm stump. Currently this is beyond me ..... Or do I need to start from scratch? (ARGH!) Here is my function function getImage($num) { global $more; $more = 1; $link = get_permalink(); $content = get_the_content(); $count = substr_count($content, '<img'); $start = 0; for($i=1;$i<=$count;$i++) { $imgBeg = strpos($content, '<img', $start); $post = substr($content, $imgBeg); $imgEnd = strpos($post, '>'); $postOutput = substr($post, 0, $imgEnd+1); $postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);; $image[$i] = $postOutput; $start=$imgBeg+$imgEnd+1; } if(stristr($image[$num],'<img')) { echo '<a href="'.$link.'">'.$image[$num]."</a>"; } $more = 0; } and here's how I use it in the html: <div class="project-slider-mask w-slider-mask"> <div class="w-slide"> <?php getImage('1'); ?> </div> <div class="w-slide"> <?php getImage('2'); ?> </div> <div class="w-slide"> <?php getImage('3'); ?> </div> <div class="w-slide"> <?php getImage('4'); ?> </div> etc etc etc Help much much appreciated....been failing at this for so long!

Is there a way to duplicate divs and increment them?

imgrooot posted a topic in PHP Coding Help

Here's a line. I want to add 100 more of same lines and increment the page numbers as shown below. I know I can just manually add 100 lines but Is there a way to do this with PHP that would make it easy? Or is this more of a javascript thing? // original $page1 = '<a href="?type='. $type_id .'&name='. $get_type_3_name_slug .'&page=1">1</a>'; // new $page1 = '<a href="?type='. $type_id .'&name='. $get_type_3_name_slug .'&page=1">1</a>'; $page2 = '<a href="?type='. $type_id .'&name='. $get_type_3_name_slug .'&page=2">2</a>'; $page3 = '<a href="?type='. $type_id .'&name='. $get_type_3_name_slug .'&page=3">3</a>'; $page4 = '<a href="?type='. $type_id .'&name='. $get_type_3_name_slug .'&page=4">4</a>'; $page5 = '<a href="?type='. $type_id .'&name='. $get_type_3_name_slug .'&page=5">5</a>'; ...etc

Creat cdata Inside Loop Without Creating Multiple cdata

codeinphp posted a topic in PHP Coding Help

Is it possible to append to cdatasection within xml file using a loop without creating a new cdata section with each loop thru. The code starts out by creating the basics for xml then enters into a loop to go thru each element of an array, appending the cdata. $xml=new DOMDocument('1.0', 'UTF-8'); $xml->preserveWhiteSpace = false; $xml->formatOutput = true; $components = $xml->createElement("components"); $name=$xml->createAttribute("name"); $name->value = "customEPGGrid"; $extends=$xml->createAttribute("extends"); $extends->value = "EPGGrid"; $components->appendChild($name); $components->appendChild($extends); $script = $xml->createElement("script"); $type=$xml->createAttribute("type"); $type->value = "text/brightscript"; foreach ($items as $item){ //ENTER INTO LOOP $cdata=$xml->createCDATASection(<<<EOT function init() m.content = createObject("RoSGNode","ContentNode") m.top.setFocus(true) dateNow = CreateObject("roDateTime") dateNow = dateNow.asSeconds() - 2000 addChannel({$item['name']}) addItem({$item['name']}, dateNow) m.top.content = m.content m.top.translation = [50, 300] m.top.numRows = 5 m.top.duration = 10800 m.top.nowNextMode = false m.top.infoGridGap = 0 m.top.channelInfoColumnLabel = "HELLO" end function sub addChannel(channelText as string) m.channel = m.content.createChild("ContentNode") m.channel.TITLE = channelText m.channel.HDSMALLICONURL = "http://css.boshanka.co.uk/wp-content/uploads/2015/04/icon-logo-design-small.png" end sub sub addItem(progText as string, timeStart) For i=0 To 5 Step 1 program = m.channel.createChild("ContentNode") program.TITLE = progText + str(i) program.PLAYSTART = timeStart + (i * 2000) program.PLAYDURATION = "2000" End For end sub EOT ); } $script->appendChild($cdata); $script->appendChild($type); $components->appendChild($script); $xml->appendChild($components); $xml->save($filename2); When executed like this, I get a new createCDATASection with each pass thru the loop. Not really wanting this, but one createCDATASection with different value or $item['name'].

Foreach loop doesn't bring all the records from the database

Hi, guys i'm trying to fetch all results from DB through a foreach loop.

Using Loop to Create String from Post Variables

dtyson2000 posted a topic in PHP Coding Help

Hello. Just a quick question about using a loop to create a string from post variables that will then be used in a query. I have several post variables submitted in a form, some of which contain a value of T. Others are not selected. In the database there are several columns which may contain values of T or may not. I would like to construct a query that searches for specific columns containing T and ignoring the rest. I'm using WHERE "T" IN(colnames). I need to get the column names into a comma separated string. Here's what I'm using: $postVal = array("1", "2", "3", "4", "5"); foreach ($postVal as $key=>$val){ $newVar = “col”.$val; if ($$newVar == "T") { *create/add to comma-separated string } else { *ignore } } I hope that seems clear enough. I'm just not sure if I'm on the right track or not. What do you think? Thank you, in advance!

input looping

old_blueyes posted a topic in Applications

Hi, I am having a small issue with a front end html form, which through a series of looped input fields will update multiple WordPress posts at once, on submisson. The issue i'm having currently, is on submission it's only updating 1 post. I have found a solution to my problem, here: http://wordpress.stackexchange.com/questions/206372/how-to-handle-dynamic-form-data-with-repeating-fields But as i am still a bit of a novice, I have tried to apply the max_id solution to my code below, so far i've not got it to work. Using the solution on the above link, I don't suppose someone could show/tell me, what the code should be in it's entirety?? Including the foreach section, thanks! foreach( $testArray as $value ) { $post_information = array( 'post_title' => $value, 'post_status' => 'publish', // Choose: publish, preview, future, draft, etc. 'post_type' => 'predictions' //'post',page' or use a custom post type if you want to ); //update post wp_update_post($post_information);

Array Question (Issue)...

dtyson2000 posted a topic in PHP Coding Help

I have the following in a form that edits values already put into a dbase. $alev = array(1 => '1', 2 => '2', 3 => '3', 4 => '4', 5 => '5', 6 => 'AP'); $dblev = explode(',',$row['hw_lev']); foreach ($alev as $key => $lev){ if(in_array($lev,$dblev)){ echo "<input type='checkbox' name='ud_lev[]' value='$lev' checked> $lev"; } else { echo "<input type='checkbox' name='ud_lev[]' value='$lev'> $lev"; } When I attempt to edit the dbase values, the following occurs: When I select the "A" checkbox, it is input into the database and reflects in the results. When I attempt to edit this, the "A" box is checked and all is well. When I select anything else AND "A" ("1", "A"), it is input into the database and reflects in the results. When I attempt to edit this, the "1" box is checked but the "A" box is NOT checked. This is what I need. I feel like the problem is with the array? But it could be the loop.. Probably something totally staring me in the face. You know how it goes. I was wondering if you see a problem in the array or in the loop. Any thoughts would be appreciated!

array looping error

unistake posted a topic in PHP Coding Help

Hi all, I am trying to calculate the straight line distance between two points by using their co-ordinates on each row from a mysql db that satisfies the query. It works fine, except the last for loop below calculates $lat[$x+1],$long[$x+1] to have blank fields as they no longer exist in the database therefore i have invalid distances calculated. My goal of this script is to find all the routes a particular day a flight attendant is working, by searching my db, rosters, then gathering the departure and arrival airport from this table. With these airports, I then extract their co-ordinates from the table, airports, and use the function below to calculate the distance. Hope it makes sense what I am trying to do below!! <?php function distance($lat1, $lon1, $lat2, $lon2, $unit) { $theta = $lon1 - $lon2; $dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta)); $dist = acos($dist); $dist = rad2deg($dist); $miles = $dist * 60 * 1.1515; $unit = strtoupper($unit); if ($unit == "K") { return ($miles * 1.609344); } else if ($unit == "N") { return ($miles * 0.8684); } else { return $miles; } } $today = '2016-01-04'; $sql = "SELECT * FROM rosters WHERE Code = 'TESTUSER' AND SectorDate = '$today' ORDER BY BeginTime ASC"; $result = mysqli_query($cxn,$sql) or die ("Cant get rosters distance."); $dep = array(); $arr = array(); $lat = array(); $long = array(); while($row=mysqli_fetch_array($result)) { $dep[] = $row['Dep']; $arr[] = $row['Arr']; } echo 'Number of flights: '.count($dep).'<br />'; foreach($dep as $key => $value) { $sql = "SELECT * FROM airports WHERE IATA = '$value'"; $result = mysqli_query($cxn,$sql) or die ("Cant get airport coordinates."); while($row=mysqli_fetch_array($result)) { $lat[] = $row['Latitude']; $long[] = $row['Longitude']; } } $max = count($dep); for ($x = 0; $x <= $max; $x++) { echo $dep[$x].' - '.$arr[$x].'<br />'; echo floor(distance($lat[$x],$long[$x],$lat[$x+1],$long[$x+1], "N")) .

Say I have this loop. foreach($record as $row) { <div class="hello">Hello World!</div> } I want to loop through and add a letter alongside the "Hello World!" above. To do that, I found this code. $azRange = range('A', 'Z'); foreach ($azRange as $letter) { print("$letter\n"); } How can I combine the two loops so that I get a result like this? A Hello World! B Hello World! C Hello World! D Hello World! E Hello World! F Hello World!

Help with parent/child array relationship

gibigbig posted a topic in PHP Coding Help

This is my database structure: http://www.awesomescreenshot.com/image/733881/57d01b042ca99b9a36dde90dd6640cdc I would like to loop through all the child elements (those who's parent_id is set to the data_id within the same table). Therefore those with "parent_id" as "0" are parents, and those with parent_id with a number in it is a child. I would like help creating a function that will generate tables, with the table itself as the parent, and all the rows within it would be children of that parent. There is only one layer of depth in this project (one parent and one child layer always. ). Can anyone help, or would want a more detailed description? Thank you, and looking forward to a reply.

PHP / Loop Question + HTML

kellyalan posted a topic in PHP Coding Help

Hello - I hope I explain this clearly... I have some php code that presently displays 4 boxes in a row with images. When you click on a box/image, you go to a web post. The code goes to the bottom, sets the link, then loops back for the next image and repeats the process. What I'm trying to do is break this code apart so that that I can make each image go to a different link - basically set it up as html - image with link to a page. ( 4 of these) However, I don't want to break the code or the page that it displays ( our home page ) Here's the code snippet: <div id="new-classes" class="carousel slide">  <div class="carousel-inner"> <?php $pieces=array_chunk($gallery,4); $j=0; foreach ($pieces as $slice) { echo '<div class="item '; if($j==0){echo 'active';} echo '">'; foreach ($slice as $i => $conte) { ?> <div class="col-sm-6 col-md-3" > <div class="new-class" > <img src="<?php echo $slice[$i]['image']; ?>" alt="//" /> <div class="class-title" > <div class="occult" > TEST this is where the specialities boxes link is <a <?php echo colors('a');?> href="<?php echo $slice[$i]['link']; ?>" class="link" ></a> I duplicated the above line and put in a specific link but it makes all the images go to the same page <a <?php echo colors('a');?> href="https://www.absolutept.com/tendinopathy/" class="link" ></a> --> </div> <h3 <?php echo colors('h3');?>><?php echo $slice[$i]['title']; ?></h3> <p <?php echo colors('p');?> class="occult" ><?php echo wp_trim_words(insert_br($slice[$i]['desc']),10,'...'); ?></p> </div> </div> </div> <?php } //end slice echo '</div>'; $j++; } // end pieces ?> </div> our homepage is absolutept.com -- these images are the "specialties" section 3/4 of the way down In the theme( wordpress) - there's an option to enter specialties ( custom post type ) which we did but we don't want these links to go to those special posts, we want them to go to the pages that the user can find in the main menu I know this is breaking the set up of the theme but if it's doable, we'd like to try First - any idea if it's doable and if so, thoughts on how? =) Thanks in advance.

Hi, I am trying to add values together in my while loop, so far I have: $q->query($DB, $SQL); while($avrating=$q->getrow()): $averageratings = $avrating['sum(rating)'] / $noofreviews; $overallaverage = round($averageratings, 2) + round($averageratings, 2); echo '<p>'.$avrating['rating_name'].': '.round($averageratings, 2).'</p>'; endwhile; echo 'x'.$overallaverage; $overallaverage += $overallaverage / 10; echo 'The Average: '.$overallaverage; from this, I get: x7.34The Average: 8.074 the total shold be: 42.34 then dived by 10 should be 4.23

Call variable outside a loop

FewFlyBy posted a topic in PHP Coding Help

Hello so I have a simple code here that will check if a random number already exists in the database and will generate a new one: $rand = mt_rand(100000, 999999); $sid = array( ":sponsorID" => $rand ); $accounts = $db->select("accounts", "sponsorID = :sponsorID", $sid) while(count($accounts) > 0) { $newNum = mt_rand(100000, 999999); } What I wanted to do is to echo out $newNum. When I echo it out I get undefined index of that variable. How can I solve this?

Creating dynamic grid table with images

servified posted a topic in PHP Coding Help

First off, I am very new to php and I am learning the best I can. I am trying to display a dynamic grid style table within a loop and display my mysql data inside of it. The data is a Image URL, directory URL, URL description, and it prints all this data as an image with a link to the gallery. The code works fine as... 5 wide x 5 down. It's supposed to look a little something like this: [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] Now that works, however when I change my rows and column variable # to 7 and 7 is when the problems start.. Here is my main code for this function: //define variables $uniqhash = ""; $modelname = ""; $email = ""; $galleryurl = ""; $gallerydesc = ""; $category = ""; $datesubmitted = ""; $gallerythumb = ""; $rows = 0; $count = 0; $columns = 0; $select = "SELECT * From `models`"; $images_rows = mysqli_query($conn, $select); $images = array(); if( empty( $images ) ) { echo 'Sorry, there was a fatal error in selecting images from database.'; } while ($image = mysqli_fetch_assoc($images_rows)) { $images[] = $image; } echo '<table align="center" border="0"><tr>'; $size = sizeOf($images) - 1; //get count of array and put into $size foreach($images as $image){ if($rows == 7) { echo '</tr><tr>'; // if our count is x wide, start a new row $rows = 0; } if ($columns == 7){ echo '</tr><tr>'; $columns = 0; } echo "<td><a href=" . $image['galleryurl'] . " target=\"new\"><img src=" . $image['gallerythumb'] . " height=\"160\" width=\"160\" alt=\"" . $image['gallerydesc'] . "\"></a></td>"; $rows++; $count++; $columns++; echo ($rows == 7 && $columns == 5 && $count != $size) ? '</tr>': ''; } echo '</tr></center></table>'; When I change $rows and $columns to 7 each it will display images like: (sample of 13 images) [] [] [] [] [] [] [] [] [] [] [] [] [] [] I would like it to print x images across for $rows and x amount of rows for $columns in a grid like fashion. If anyone can give me some help on this I would appreciate it...I have been desperately reading up on loops trying to figure it out but so far no luck. P.S I am familiar with sanitizing all my data and that I need to implement this but I want to make sure my code functions first.

Need help with using session outside foreach loop

helloworld001 posted a topic in PHP Coding Help

I am having a bit of issue. I have a simple query that loops to find each record, like this. // select query here if(count($result) > 0) { foreach($result as $row) { $userid = $row['user_id']; $_SESSION['userid'] = $userid; } } else { // error here } I want to use the "$userid" on a different page; so I created a session for it. When ever I use that session on another page, it gives me only the last record's user id and not the first one. How can I fix this?

Why is this not looping?

piearcy posted a topic in PHP Coding Help

How come this doesn't loop? Everything is in the while loop. My database connection is in the included file you see to begin the code which is what db_conx refers to just to be clear. Database connection is not an issue nor is getting values. I just get the first one and nothing more. No looping taking place here. What I miss? require('includes/db_connect.php'); $query = "SELECT * FROM events ORDER BY displayorder ASC"; $result = mysqli_query($db_conx, $query); while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) { $pid = $row["id"]; $title = $row["title"]; $date = $row["date"]; $info = $row["info"]; $linkTxt = $row["linkTxt"]; $link = $row["link"]; $message = "<div id='events_holder'><table width='500' border='0' cellspacing='0' cellpadding='10'> <form action='edit_event_parse.php' method='post'> <tr> <td class='prayer_title'>Title:</td> <td><input type='text' name='title' class='admin_input' value='" .$title."' /></td> </tr> <tr> <td class='prayer_title'>Date:</td> <td><input type='text' name='date' class='admin_input' value='".$date."' /></td> </tr> <tr> <td class='prayer_title'>Link Text:</td> <td><input type='text' name='linkTxt' class='admin_input' value='".$linkTxt."' /></td> </tr> <tr> <td class='prayer_title'>Link URL:</td> <td><input type='text' name='link' class='admin_input' value='".$link."' /></td> </tr> <tr> <td class='prayer_title'>Event Details:</td> <td><textarea name='info' cols='20' rows='10' class='admin_area'>".$info."</textarea></td> </tr> <tr> <td><input type='hidden' name='pid' value='".$pid."' /></td> <td><input name='submit' type='submit' value='Edit Event' class='admin_submit'/></td> </tr> </form> </table> <p> </p> <hr /> <p> </p> </div>"; } Thanks!
