The AJAX request is failing to reach the server

I'm currently using AJAX to populate a dropdown, but for some reason the call isn't reaching the server. Upon checking Firebug, I see the following error:

POST 0
status 404 not found

This is the code I'm working with:

function selectChildCategory(parent,child){
    var url = "<?php echo url::site('admin/video/showSubCategory/')?>";
    if(parent != "")
    {
            if(child != 0){
               url = url+parent+"/"+child;
            }else{
               url = url+parent+"/"+0;
            }
            $.ajax({
                url: url,
                type:"POST",
                success: function(select)
                {
                    //alert(select);
                    $("#sub_category").html(select);
                }
            });
    }
}

The parameters seem to have correct values, but the call isn't reaching the server even though the URL is accurate.

Your advice on this matter would be greatly appreciated.

Answer №1

When you encounter a 404 Error code, it indicates that the page you are attempting to access does not exist.

If you are constructing an HTTP path using your parent and child variables but the resulting URL does not exist (or is not matched by any mod_rewrite rules), a 404 error will be displayed.

For example, if the parent is "0" and the child is "0," does the URL /admin/video/showSubCategory/0/0 actually exist?

Additionally, make sure that mod_rewrite is properly configured.

Before anything else, try manually entering the URL to verify if the JavaScript-generated URL truly exists.

Answer №2

Make sure to verify if the URL can be accessed through a POST request.
