Question

I have two javascript files, call it

• test1.js
• test2.js

they are used to request data from the php file using the following:

var xmlhttp= new XMLHttpRequest();

xmlhttp.open("GET", "../forum/getSomething.php", true);
xmlhttp.send();

and I have a php file which is used to do some queries and return the encoded json obj back to one of the js files above, call it

• getSomething.php

my question is, how can I tell which file js is making the request to the php? Ultimately, I want to state a condition and do something like the this:

# inside getSomething.php

# conditional statements
if request from test1.js
    do A
else if request from test2.js
    do B

Any tips would be helpful, thanks

You can use HTTP_REFERER with HTTP_X_REQUESTED_WITH but it can be tricky I’ll advice you can to identify each js request with ID

Example

  xmlhttp.open("GET", "../forum/getSomething.php?action=test1", true); 

Then PHP

switch ($_GET['action']) {
    case "test1" :
        // Do Test 1
        break;

    case "test2" :
        // Do Test 2
        break;
}
