Mike Smullin’s — AJAX Comments 2.0 — is probably one of the best ways you could spice up your WordPress Blog with AJAX.

Demo: Click “Add comment” on this Post and after writting “Hit Submit” Button. You will see an AJAX throbber and the comment will be submitted without refreshing or leaving the page.

Features:

• comment form validation happens server-side without refreshing or leaving the page
• Script.aculo.us Fade In/Out Effects make readers happy
• works with AuthImage captcha word verification plug-in to prevent comment spam
• still works traditionally if browsers don’t support JavaScript (or have it disabled)
• uses existing theme code to match styled comment threads when producing new comments
• 25-second server timeout ensures readers aren’t left hanging
• works in current versions of Firefox, Internet Explorer, Opera, Netscape, and Safari.

Recommendations: (Works well, if you don’t have any of the under mentioned)

• perfectly compliments any well-styled comment form—don’t design without it
• best when moderation is off (seems more real-time) and AuthImage is installed (self-moderation is the best moderation)

How to implement:

1. Download ajax-comments v2.07
2. Unzip/upload to /plugins directory.
3. Activate via WordPress Plugins tab.

AuthImage Integration:

(optional)

• Open ajax-comments.php and uncomment lines: 92, 152, 153.
• Open comments.php from your /themes directory and use the following code (mostly just the ids) for AuthImage to appear in your comments form:

<?php if ( !$user_ID ) : ?>
<img id="auth-image" src="<?=get_option('siteurl')? />/wp-content/plugins/authimage/authimage-inc/image.veriword.php" alt="Verification Image" />
<p><label for="code">Word Verification (<a href="#" onclick="document.getElementById('auth-image').src+='?'+Math.random();return false" title="Generate another Captcha Word Verification image.">can't read it? try another!</a>)</label></p>
<p>Please type the letters you see in the picture.</p>
<p><input name="code" id="code" type="text" /></p>
<?php endif; ?>
