jquery inquiry: passing message without a new pageload
<p>Please forgive the awkwardness of this question, I honestly don't know how to phrase a better query...</p>

<p>The situation:</p>

<p>I have a basic contact form within an xhtml/php page that I'm in the process of upgrading.  I recently added a new unrelated jquery plugin on this page, so I would like to use the jquery functionality to help with some simple form validation if possible.  The validation is already being done via PHP in a separate file submitted by the contact form.</p>

<p>What I want to happen, is for the PHP validation message to be passed back to the main (contact form) page without a new pageload.  I've seen this done by means of jquery somewhere, but I can't seem to find it again either here or via google.  Can anyone help?</p>

<p>I'm really looking for speed and simplicity here, and at first glance, the jquery validation plugin is daunting in its size and complexity, so I'm loath to embark on that particular route...</p>
