ProcessWire and JQuery AJAX

[nickmccomb]

Hi guys,

i've been trying to fix an issue all day and can't figure it out!

i have a php page that calls another php page through AJAX.  The problem is that the session variables i set in the page i call through AJAX don't stick when i go back to the calling page.

I believe it may be because of the way i'm calling the page url with AJAX, which could be what makes another session once it gets to the AJAX page  

     url:"<?php echo $config->urls->templates?>logincode.php/",

the session ID's are completely different on both pages and the name of the session from the calling page is 'wire'.  The name of the session on the AJAX page is called 'PHPSESSID'.   So the sessions are not the same, which is why the session variables set in the AJAX page aren't available in the calling page when the AJAX page is returned to the calling page.  

i've tried renaming the ProcessWire session name in the config file to 'PHPSESSID', although that didn't work.  

When i go to the page 'logincode/' as a regular post from a form it works perfectly and has the same session ID and variables, although through AJAX the sessions on both pages are completely different.  

Does anyone know how to do this properly and make the session the same?  Please help, it's driving me mad!

see the AJAX calling code below:

$.ajax({ 

     type : 'POST',

     xhrFields: {withCredentials: true},

     data : {'username':username, 'password':password},

     url:"<?php echo $config->urls->templates?>logincode.php/",

     success:function(result){  

          if(result == "1"){

               alert('Please input username and password');

          }

     }, 

error:function(xhr, status, error) {  

     alert('error');

} 

});

First thing, calling the template files directly won't work by design. Try to address real URLs, meaning implementations of these template(s). In the template files you can detect whether the page is called via AJAX:

<?php
if($config->ajax) {
    // page was requested from ajax
}

Once you changed this, the session management should work, I think.

i've also tried setting the AJAX url to:

url:"<?php echo $config->urls->templates?>logincode/",

to try and load it through processwire, but my AJAX call returns an error (which is set up as a javascript alert).  I'm guessing AJAX doesn't understand it's in ProcessWire so it can't find the page at all when doing it this way, so trying it this way also did not work

I think it's easier to place files that are called via ajax from a directory outside of the PW "site" directory, eg: www.mysite.com/ajax/ajax.php

Why are you refering to the paths inside the template folder? This would return an error even if you wouldn't call it via AJAX. Try: 

url: '<?php echo pages->get('/logincode/')->url ?>'

marcus thankyou!  

i think you missed out a $ sign thought, but i got it to work using:

url: '<?php echo $pages->get('/logincode/')->url ?>'

finally!  Thank you so much.  I should really have posted in here 8 hours ago although i wanted to figure it out myself, and learnt a hell of a lot by trying

Thanks mate!
