using helpers outside the systems folder

I have not found a perfect solution for this.
One thing you can do is write your ajax functions so that they take a parameter called URL and then call that function from within your view file and use a php brace there where you echo the value you need.

Code:

[removed]
$("form").submit(function(){  
    ajaxFunction(<?php echo uriHelperFunc() ?>);
});
[removed]

Or you can just practice bad coding practises and put all your javascript in your view files and then you can put php wherever you want (what i did)
