   Hi,

   I am trying to call a Javascript function from a PHP if-else function. The if-else function itself and the else part are working fine, I just can't get the Javascript to run when the if condition is met.

   I have tested the Javascipt code by dropping it into a plain html page and there it runs fine.

   Would anybode here know what I'm doing wrong??

   Thank you,
   diederik

   Here is the code:

   <?php if('the_title'!=="At Random Play") : ?> <?php echo '<div id="flashcontent">
    <strong>XML gallery</strong>
   </div>
   <script type="text/javascript">
    var so = new SWFObject("http://www.theblacksnapper.net/wp-content/uploads/2009/random_play_2009/gallery.swf", "", "620", "503", "8", "#ffffff");
    so.addParam("allowScriptAccess", "always");
    so.addVariable("xmlfile", "http://www.theblacksnapper.net/wp-content/uploads/2009/random_play_2009/xml/images.xml");
    so.write("flashcontent");
   </script>'; ?> <?php else : ?> <?php echo get('part_flash');?> <?php endif; ?>

   I have the sfwobject in my header like this:
   <script type="text/javascript" src="http://www.theblacksnapper.net/swfobject.js"></script>

   Here are my suggestions:

   1. The if else looked a little odd. You had a !== which I've never heard of... :)
   2. I've broken everything in to a few echo calls so we can see what's going on.
   3. When you next call this, can you look to see if there are any JavaScript errors? Here's how you find these in Internet Explorer. For Safari go: Page -> Develop -> Show Error Console; Firefox: Tools -> Web Development; and Chrome: Page -> Developer -> JavaScript console.

   So, here's some code:

   <?php 
   
   if(the_title()!="At Random Play") { 
   
       echo '<div id="flashcontent"><strong>XML gallery</strong></div>';
       echo '<script type="text/javascript">';
       echo 'var so = new SWFObject("http://www.theblacksnapper.net/wp-content/uploads/2009/random_play_2009/gallery.swf", "", "620", "503", "8", "#ffffff");';
       echo 'so.addParam("allowScriptAccess", "always");';
       echo 'so.addVariable("xmlfile", "http://www.theblacksnapper.net/wp-content/uploads/2009/random_play_2009/xml/images.xml");';
       echo 'so.write("flashcontent");';
       echo '</script>'; 
   
   } else {
   
       echo get('part_flash');
   
   };
   
   ?>

   diederik.meijer,

   Were you able to get this to work? I'm trying the same thing. If so, will you give an example?

   Hey, mine works now. I just needed to add the full URLs.

   function getCustomField()
   {
   	global $post;
   
   	$video = js_escape(get_post_meta($post->ID, 'video', true));
   	$vid_place = js_escape(wp_get_attachment_url($video));
   
   		if($video) : ?>
   
   <script type='text/javascript' src='http://actual/path/to/swfobject.js'></script>
   <p><div id='<?php echo $video;?>'>This text will be replaced</div></p>
   <script type='text/javascript'>
     var so = new SWFObject('http://actual/path/to/player.swf','ply','470','320','9','#ffffff');
     so.addParam('allowfullscreen','true');
     so.addParam('allowscriptaccess','always');
     so.addParam('wmode','transparent');
     so.addVariable('file','<?php echo $vid_place;?>');
     so.write('<?php echo $video;?>');
   </script>
   <?php
   
   endif;
   
   }

   I got the hint from this post.
