Trouble with javascript if statement - php

Question

Ok, I'm making a login and registration panel with jquery and php. In short, if there are errors with the registration it sets a few form errors, redirects back to the registration page, the javascript detects there are errors with the use of a php variable and forces the slider to show itself.
The working code: Above the doc type $errors = $form->num_errors; and the whole $errors routine works fine.
My problem is that I also have a verification that the form was submitted successfully. It uses
if(isset($_SESSION['regsuccess'])){
$success = 1;
} else {
$success = 0;
}
to set the $success variable. The crazy thing here is that this doesn't work using the same routine as the $error variable. I know the $success conditional is working correctly as I have an it echoed out further down the page.
jQuery slide script:
$(document).ready(function() {
var num_errors = "<?php $errors; ?>";
var form_success = "<?php $success; ?>";
// Expand Panel
$("#open").click(function(){
$("div#panel").slideDown("slow");
});
// Collapse Panel
$("#close").click(function(){
$("div#panel").slideUp("slow");
});
// Switch buttons from "Log In | Register" to "Close Panel" on click
$("#toggle a").click(function () {
$("#toggle a").toggle();
});
//this part works
if(errors>0){
$("div#panel").slideDown();
$("#toggle a").toggle();
}
//this part doesn't
if(form_success>0){
$("div#panel").slideDown();
$("#toggle a").toggle();
}
});

Suggestions would be appreciated, thanks!

In your page, you have an errors variable defined, that's why that portion works:
<script type="text/javascript" language="javascript">
<!--
errors = 0; // -->
</script>
Your javascript file isn't processed by php, it's served directly by the web server so your variables in what you listed above:
var num_errors = "<?php $errors; ?>";
var form_success = "<?php $success; ?>";
Those come out exactly that way to the client, they aren't replaced with their values. You need to move those 2 lines into your page where you have errors now, and remove them from quotes as well. Take them out of your js and use this in your page:
<script type="text/javascript" language="javascript">
var num_errors = <?php $errors; ?>;
var form_success = <?php $success; ?>;
</script>
