Need help debugging an issue with Load Plugin To Div Behaviour

So I have a page which I load a page into a div via the regular static plugin like so:

<?php
if("" == ""){
$WA_display_quote_1472681007248 = new WA_Include("display-quote.php");
require($WA_display_quote_1472681007248->BaseName);
$WA_display_quote_1472681007248->Initialize(true);
}
?>

and this works fine but when I try to replace the content of the div on form submit (within a jQuery function) like so:
$('#frmModelAdd').on('submit', function(e){

// prevent default form submission
e.preventDefault();

framework_load_plugin_url('plugins/display-quote.php',false,'displayQuote','../../../../','');return document.MM_returnValue;

});

I get the following error message:

Warning: chdir() [function.chdir]: No such file or directory (errno 2) in /Users/davidbuchholz/Sites/*********/webassist/framework/ajax_wrapper.php on line 22
Framework file not found: _plugins/site-pages/public/sales-plus-pages/display-quote.php

The site uses pretty URL's so the actual URL of the page is formatted like so:
http://sitename/salesplustools/create-quote/

I am assuming this is a path issue and I have tried changing the "../../../../" portion of the code without any success.

I will put the files online shortly and include links etc. in a private message.

The mod rewrite is throwing it off. When the url displayed doesn't match the actual path to the file you have to use a <base> tag to tell the ajax what the actual base page is.

I've added that to the index page with:

<base href="http://<?php echo($_SERVER['SERVER_NAME']); ?><?php echo($_SERVER['PHP_SELF']); ?>">

That appears to have fixed the problem.

wonderful, thanks Ray

I didn't know about the base tag trick so I will store that in my knowledge base
