Call PHP Function using jQuery AJAX

Question

I\'ve read all the topics about my question but cannot solve my problem. I want to get php function result using jQuery AJAX.

function.php

function g         


        

Answer 1

What I do is in JavaScript I pass PHP function name which I want to call. Like..

function MyFunction() {
jQuery.ajax({
    type: "GET",
    url: "function.php",
    data: "call=generateCode",
    success: function(response){
        //do something
    });
}

Here in data field "call" variable have function name to call from "function.php" file.

in "function.php" I place below code to call the function

if($_SERVER['REQUEST_METHOD']=="GET") {
$function = $_GET['call'];
if(function_exists($function)) {        
    call_user_func($function);
} else {
    echo 'Function Not Exists!!';
}
}
