Ever got annoyed when submitting a comment on a wordpress blog and just getting a blank page with a error message like “please fill out required fields” and nothing else? This plugin aims to help by adding validation to the comment form. When a user submits the form and something is missing, an appropiate message is displayed and individual fields are highlighted. When the email or url is in an incorrect format, a message is displayed accordingly.
Why should you install it? Because you care for comments and want to help users reduce mistakes that hold them off from commenting at all.
Whats the technology used? <a href="http://jquery.com" rel="nofollow ugc">jQuery</a> and the <a href="http://bassistance.de/jquery-plugins/jquery-plugin-validation/" rel="nofollow ugc">jQuery Validation plugin</a> with a few customizations to make it fit into the standard WordPress theme.
Is it compatible with other plugins? The plugin is tested with the <a href="https://wordpress.org/extend/plugins/draw-comments/" rel="ugc">Draw Comments</a> plugin and works, though the performance is slightly degraded. Other plugins haven’t yet been tested.

Comment Validation

This plugin adds client-side validation to the Wordpress comment form, using the jQuery validation plugin.

Whenever you plan to begin developing applications on WordPress using AJAX technology, you have to solve a number of 
minor issues unrelated to the logic of your application:
<ul>
<li>How to package and transmit data from the browser to the server, so they will not have been distorted?</li>
<li>How to transfer data, if they are multi-dimensional array?</li>
<li>How to implement a custom processing of AJAX response in case, again, it represents a complex set of data (a typical 
example – form sending and on-server validation)?</li>
<li>How to handle data transition errors?</li>
<li>How to debug all this stuff?</li>
</ul>
Usually these issues generates a lot of spaghetti code, moreover, each new request type requires some customization of 
code. Managing all of this, you forget about the function that you would like to implement.
AJAX Manufactory plugin for WordPress have most of these tasks already solved. You can think about functionality and 
business logic instead.
What you can have from the box:
<ul>
<li>A simple function at the client side which allows to send any your complex data from javascript to WordPress server 
side.</li>
<li>An AJAX response wrapper at the server side which gives to you sent data as PHP array and allows you to create 
an AJAX response as a set of simple “commands” like “make an alert”, “set up javascript variable”, “put html text to 
specific html node(s)”, “execute a javascript function”, “go to specific URL” etc.</li>
<li>Automatic execution of “commands” queue at the client side. Additionally you can specify your own callback.</li>
</ul>
