copied!<p>Damm, beaten to the answer!</p> <p>The reason why you were getting a "process_form.php" aborted message in Firebug was from your page refreshing itself before the "process_form.php" could reply to the original query, hence it was aborted! If there's no action in the FORM statement, the page assumes a refresh.</p> <p>For my pennies worth, I try and avoid using jQuery to event handles such as POST and GET, since normally the page then tries a refresh (since no action was declared in the form statement).</p> <p>I use the following code for the client side, with the PHP returning a formatted XML document.</p> <pre><code><body> <form id="subscription"> <input id="1" value="1"> <input id="2" value="2"> <input id="3" value="3"> <input id="4" value="4"> <input type="button" value="SUBMIT" onclick="submitForm()"> </form> <script type="text/javascript"> $(document).ready(function() { }); function submitForm() { $.post("./process_form.php", $('#subscription').serialize(), function(xml) { alert($("SUCCESS",xml).text()); }, "xml"); }; </script> </body> </code></pre> <p>Server side PHP:</p> <pre><code><?php header("Expires: Mon, 26 Jul 1997 05:00:00 GMT" ); header("Last-Modified: " . gmdate( "D, d M Y H:i:s" ) . "GMT" ); header("Cache-Control: no-cache, must-revalidate" ); header("Pragma: no-cache" ); header("Content-Type: text/xml; charset=utf-8"); $XML = '<?xml version="1.0"?>'; $XML .= "<ROOT>"; $XML .= "<SUCCESS>1</SUCCESS>"; $XML .= "</ROOT>"; echo $XML; ?> </code></pre> <p>This allows for validation at the server side easily and for the validated answer to be returned easily. (For example: validating against a database, return with SUCCESS=0 and the reason why REASON=Not in database.)</p>
