JQuery Ajax 500（内部服务器错误）

Question

I'm utilizing the jquery library to make an ajax call to a php file. Everything was working fine when the path was relative like this:

url:"fetch_term_grades.php",

But when I change the path like this:

url:"includes/ajax/fetch_term_grades.php",

I'm getting this error from the console:

jquery-2.2.3.min.js:4 POST http://localhost/SchoolMate/includes/ajax/fetch_term_grades.php 500 (Internal Server Error)

This is my ajax code:

$.ajax({
        url:"includes/ajax/fetch_term_grades.php",
        method:"post",
        data:{"term":term},
        dataType:"text",
        success:function(data){
            $("#result").html(data);               
            $('#dataTable').DataTable();
            //$('table').attr('id', 'dataTable');  
        }

      });

Answer 1

url:"includes/ajax/fetch_term_grades.php"

this is still a relative path as I understand. Try with / at the beginning like / + actual path to that script in your filesystem. Maybe it is url:"/includes/ajax/fetch_term_grades.php"

Answer 2

It depends on which location you are calling that script from. In your case the file that calls the scripts is located under the same folder which is includes/ajax/fetch_term_grades.php. If you want to call it using this url includes/ajax/fetch_term_grades.php you should put two layers up, ie: it should be side by side with the includes folder.
