   I have a large javascript file that I don't want to include on all pages. I would to only load it when the corresponding plugin is loaded. It's loaded when the post contains a specific keyword.

   Here's a simplified version of my code:

   <?php
   
   if ( !is_admin() )
   {
   	add_action('wp_head', 'set_js_vars');
   	add_filter('the_content', 'load_php_class_file', 9);
   
   	wp_enqueue_script('myJSlibrary', plugins_url('bigfile.js', __FILE__), array('swfobject'), 1.0);
   }
   
   function set_js_vars()
   {
   	print "<script type='text/javascript'>\n";
   	print "	foo = 'bar';\n";
   	print "</script>\n";
   }
   
   function load_php_class_file ( $content = '' )
   {
   	if ($content == 'special_code')
   	{
   		ob_start();
   		require_once( dirname(__FILE__).'/plugin.php' );
   		return ob_get_clean();
   	}
   
   	return $content;
   }
   
   ?>

   When I move the wp_enqueue_script() call inside the load_php_class_file(), it doesn't seem to work. Am I missing something?

   I use this to check for [add_the_js]:

   function insert_the_js($posts)
   {
   	if (empty($posts))
   	{
   		return $posts;
   	}
   
   	$found = FALSE;
   
   	foreach($posts as $post)
   	{
   		if(stripos($post->post_content, '[add_the_js'))
   		{
   			$found = TRUE;
   			break;
   		}
   	}
   
   	if($found)
   	{
   		wp_enqueue_script(
   			'my_script',
   			'http://....'
   		);
   	}
   
   	return $posts;
   }
   add_action('the_posts', 'insert_the_js');
