Question

Fellow Coders,

so far I have been using the CI url helper to build full urls using base_url() and site_url(). Now I’m trying to access a controller function within some javascript code that will be loaded as a js file.

it’s actually an ajax call with a url parameter that should be something like:

url : '/account/check_user'  

now unless i prefix the url with the full path as ins http://servername/….. the code fails.

all the code examples i’ve seen use the short version of the url but i cannot get it to work. I’m sure this is really simple but i’m stuck.

i could pass a hidden form field to the js code but i’d rather not. any ideas?

thanks

Well, I also tend to use absolute URLs and a good practice I always do is declaring a JS variable:

var base_url = "<?php echo base_url(); ?>";

In:

1. the head section
2. as the first line of my script tag
3. if I have a main.js file that holds most of my JS code AND it’s always included in my views, then I put that line first thing in the file.

After that, you use it like:

url : base_url + 'account/check_user'

Anyway, the first slash / in your url tells the browser to go to the URL root which would not be the right place to put your url chunk in! for example:
if your CI installation is in ci folder and your URL is: domain.com/ci/contorller/method/
Then your URL will become: domain.com/contorller/method/!!
