title: How to use jQuery within PHP
body: <p>I'm using a php tree browser that I got from <a href="http://www.lateralcode.com/directory-trees-with-php-and-jquery/" rel="nofollow">http://www.lateralcode.com/directory-trees-with-php-and-jquery/</a></p>
  
  <pre><code>&lt;?php
   $path = ".";
  
   function createDir($path = '/')
   { 
    if ($handle = opendir($path)) 
    {
     echo "&lt;ul&gt;";
  
     while (false !== ($file = readdir($handle))) 
     {
      if (is_dir($path.$file) &amp;&amp; $file != '.' &amp;&amp; $file !='..')
       printSubDir($file, $path, $queue);
      else if ($file != '.' &amp;&amp; $file !='..')
       $queue[] = $file;
     }
  
     printQueue($queue, $path);
     echo "&lt;/ul&gt;";
    }
   }
  
   function printQueue($queue, $path)
   {
    foreach ($queue as $file) 
    {
     printFile($file, $path);
    } 
   }
  
   function printFile($file, $path)
   { 
    echo "&lt;li&gt;&lt;a style=\"cursor:pointer\" ".
         "onClick=\"parent.right.document.getElementById('file_path').value='".
         "$file_path'\"&gt;$file_path&lt;/a&gt;&lt;/li&gt;";
   }
  
   function printSubDir($dir, $path)
   {
    echo "&lt;li&gt;&lt;span class=\"toggle\"&gt;$dir&lt;/span&gt;";
    createDir($path.$dir."/");
  
   ?&gt;
  
   **&lt;script language="javascript"&gt;
     $(document).click(function(e) { 
     if (e.button == 0) {
      // was the left button
      alert('clicked'); 
     }
    });
    &lt;/script&gt;**
  
   &lt;?php 
    echo "&lt;/li&gt;";
  </code></pre>
  
  <p>However, I want to detect a right-click that is pressed inbetween, so that I can trigger an event. However, I can't seem to get the jquery code to work within my PHP. The reason being, that I don't get an alert popup when I execute the code ... Ideally, I want to have this included within my php code, since I need to use my php <code>variable $file_path</code></p>
