[Exequiel]

Hello friends, i want to know if how to call a php oop class function like mainCategory using ajax, this is the code for ajax,

 
var d = "Zick";
$.ajax({
        type: "post",
        url: "e_class.php/mainCategory",
        data:{
            d:d
        },
        success: function(inlog){
            alert(inlog);
        }
    });
 

and this is for the php

class E_class
{
 
    public function mainCategory()
    {
        echo $_POST['d'];
    }    
 
}
 
 

I made it with codeIgniter but without codeigniter i can't call the funtion, , any reply are appreciated. . :D

you cannot call a class directly from AJAX, only a whole script. (but you can of course use an URL that indicates you want a certain class to be called).
