• PHP sleep accuracy

  - by Abs

  Hello all, I use the following code to see how long a user is on a particular page. I use a hidden image with a src attribute to this script: $timer_seconds = 1; while(!connection_aborted()) { echo "\n"; flush(); sleep(1); $timer_seconds++; } I sometimes find this can be off by 5-10 seconds! I am guessing its the load of the server that effects the timing?? Is there anyway I can make this accurate? Thanks all for any help.

• Stopping an if clause along with the whole PHP script, but not HTML

  - by user626816

  Hello there, I've been having this problem for around an hour, and have searched the internet for answers. I've checked the PHP documentation, looked around, Googled, nothing. Anyways, my problem is that after I try to validate something (and it's wrong), if I use exit; it will also stop the HTML after. Here's what I'm talking about: if ($_POST['exampleEmail'] == "") { echo "Please enter an e-mail."; //Now I want only the PHP script to stop, however... exit; //If I use exit, then the HTML after this script (footer) doesn't show. } If anyone can help, please do. I've tried using break, but to no avail, since it's only for loops and switches. If there is a better/more correct (or simply correct if this is the wrong way), please share. I've had this problem in the past, and I just used exit then. Thanks.

• Check if a variable is empty

  - by Thomas

  I have some user-submitted variables that I want to display in a different part of my site like this: <div class="pre_box">Term: </div> <div class="entry"><?php $key='term'; echo get_post_meta($post->ID, $key, true); ?></div> Occasionally, these variables might be empty in which case I don't want to display the label for the empty variable. In the example above I would want to hide the <div class="pre_box">Term: </div> part. Is there some simple way to check if a php variable like the one above is empty and prevent the label from being displayed?

• Hyperlinks within a table - '<a href="">'.$row['username'].'</a>'

  - by Taimur

  Hi, I have made a leaderboard table on my site, which returns the users in the MySQL database with the highest scores (score is a separate field). The fields in the leaderboard table are 'rank' 'username' and 'score'. I would like to link each username in the table to it's own profile page. The profile pages are in the format /profile.php?user=$username. How would I go about adding an <a href> within the table (which is echoed in php): echo '<tr><td>' .$a. '</td><td><a href="profile.php?user=' .$row['username']. '">' .$row['username']. '</a></td><td>'.$row['count'].'</td></tr>'; I've tried the above, but it doesn't seem to work. It shows the usernames, but they don't have any hyperlinks. Thanks

• PHP unserialize fails with non-encoded characters?

  - by FFish

  $ser = 'a:2:{i:0;s:5:"héllö";i:1;s:5:"wörld";}'; // fails $ser2 = 'a:2:{i:0;s:5:"hello";i:1;s:5:"world";}'; // works $out = unserialize($ser); $out2 = unserialize($ser2); print_r($out); print_r($out2); echo "<hr>"; But why? Should I encode before serialzing than? How? I am using Javascript to write the serialized string to a hidden field, than PHP's $_POST In JS I have something like: function writeImgData() { var caption_arr = new Array(); $('.album img').each(function(index) { caption_arr.push($(this).attr('alt')); }); $("#hidden-field").attr("value", serializeArray(caption_arr)); };

• Reload AJAX data every X minutes/seconds, jQuery

  - by NightMICU

  Hi everyone, I programmed a CMS that has a log of who has recently logged into the system. Presently, this data is fed into a jQuery UI tab via Ajax. I would like to put this information into a sidebar on the main page and load it via AJAX every 30 seconds (or some set period of time). How would I go about doing this? Does the PHP response need to be JSON coded? I am fairly new to AJAX and JSON data. Here is the PHP I am currently using to pull details from the users table- <?php $loginLog = $db->query("SELECT name_f, name_l, DATE_FORMAT(lastLogin, '%a, %b %D, %Y %h:%i %p') AS lastLogin FROM user_control ORDER BY lastLogin ASC LIMIT 10"); while ($recentLogin = $loginLog->fetch()) { echo $recentLogin['name_f'] . " " . $recentLogin['name_l'] . " - " . $recentLogin['lastLogin']; } ?> Thanks!

• Running Javascript in PHP

  - by Zero

  I'm loading an external .php file using: <script type="text/javascript" src="myfile.js.php"></script> Within the external myfile.js.php file, I'm using: <?php header('content-type: text/javascript'); $message = "Test message"; ?> document.write('<?php echo $message; ?>'); Everything works fine until I change the name of myfile.js.php to just myfile.php Why does it stop working if I remove the .js part from the file name? I'm serving the file as text/javascript, plus shouldn't the .js part be ignored since .php is the actual file extension? Does anyone know why? Thanks!

  hi <?php class myClass { var $input; var $output; function myClass($input) { $output = 'You entered: ' . $input; return $output; } } $test = new myClass; echo $test->myClass(123); ?> this works, but returns this warning: Warning: Missing argument 1 for myClass::myClass() I read in to this, and seems that the constructor is expecting a value, so by adding: function myClass($input='') the warning is removed, but this seems so unnecessary? could someone enlighten me as to why it's required to define a value to prevent that warning? thanks for any pointers

  Hello I'm trying to teach myself Drupal and I've found something I can't find any tutorials for. I am trying to generate a form, with a dynamic number of text fields, to populate and edit the contents of my custom table.

• Scraping non-absolute URL

  - by cooldude

  I am trying to scrape www.weather.bm. I want all 10 radar images, but I can only get one (the image updates regularly) and it's not a absolute image url. I was hoping I could use the image as a image slideshow like the link but dont know how. Also, how can I remove images/Radarlegend.png? I just need the radar images. Here is my code: include('simple_html_dom.php'); $html = file_get_html('http://www.weather.bm/radarMobile.asp'); foreach($html->find('img') as $element) echo $element->src . '<br>' My output is: <div id="main"> images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1556.jpg<br>images/Radarlegend.png<br></div> </div>

• Passing along variable inside link works only on first word in multiple-word-variables, why?

  - by Camran

  I have this code below. As you can see I am passing two variables along with the link. The second variabye (category) works whenever it consists of one word, but some categories are two words or more, and then on the receiving php page where I fetch the variable only the first word is fetched. Any ideas? Example: I pass along this: Rims & Tires Only this comes through: Rims $display_table .= "<a href='../ad.php?ad_id=$row[ad_id]&category=$row[category]' target='_parent'>"; Here is how I fetch it in the receiving php file (which the link is to): $cat = $_GET['category']; echo $cat; //displays only first word of multiple word categories. Thanks

• PHP Casting as Object type in foreach Loop

  - by Coulton

  Within the following code, $quiz_object->personalities contains an array of Personality() objects. // Loop through each personality that exists for the quiz foreach($quiz_object->personalities AS $existing_personality) { // Show all of the existing personalities echo $existing_personality->GetQuizMakerPersonalityHTML(); } How do I "cast" (I think that's the right word) my variable $existing_personality within the foreach loop as the object type? I wish to do this so that when I type $existing_personality->, I get the list of public functions available for that object type. At the moment, Zend doesn't know that it refers to a Personality object within the loop.
