title: Jquery.post() sends variables, but PHP shows them empty?
body: <p>I'm working on a script right now for a simple shout box. I was using $.get() before without any issues. I then switched over to $.post() so I can pass Cyrillic characters to php.  </p>
  
  <p>I switched over everything to post already in both the javascript and php files. Firebug shows that the variables are not empty and being sent and their is a standard response from the php script, but not the right one. I tried printing the whole $_POST variable scope, but just gives an empty array. What am I doing wrong?  </p>
  
  <pre><code>$.post('file.php', { sc_com:'submit', name:userboxVal, color:swatch, msg:escape(msgboxVal) }, function(data) {
      if(data.error) {
          msgbox.focus();
          shoutError(data.error);
      } else if(data.status=='posted') {
          msgbox.val('').focus();
          refreshShouts(opts,'ajax');
      }
  }, 'json');
  </code></pre>
  
  <p>PHP  </p>
  
  <pre><code>$sc_com = strip_tags($_POST['sc_com']); // Empty
  print_r($_POST); // returns Array()
  </code></pre>
  
  <p>Not sure why you would need the PHP code for it? The whole thing is over 500 lines, but that is the most important part...</p>
