I am trying to render content generated by a php file in [jQuery Colorbox][1] through AJAX in my WordPress site. The PHP resides on the same server in the same domain. It works perfect when I run it on localhost but it's not working on the server.

Here is the link to my site - http://shabdcreatives.com/portfolio

The links themselves are not invalid, for example the following link works fine on its own:


I just won't open inside the colorbox.

Also the php file I am trying to load is just a fragment and DOES NOT CONTAIN any or tags.

I tried the colorbox support group but no replies from them yet

This is the code in the CatGridPost.php file that i am calling in the colorbox.. i tried calling a plain text file too... it returned no error.. but the colorbox did not show its contents either

$thepost = get_post($_GET["ID"]);
$thecontent = $thepost->post_content;
$thetitle = $thepost->post_title;
$thelink = get_permalink($_GET["ID"]);
<div id="cg-post-container">
<div id="cg-post-title">
<a href="<?php echo $thelink; ?>"><?php echo $thetitle; ?></a>
<div id="cg-post-content">  
    <?php echo $thecontent; ?>

You should not load wp-blog-header.php yourself.

Use wp-admin/admin-ajax.php instead, as described here:

  • Since you're loading WP manually, it's sending a 404 header, while also outputting the correct content. Let me know what exactly is unclear in the tutorial I linked to.

  • I would suggest getting the code on the codex working, then figure out how to modify it for your case.
