Question

I’m having problems with passing variables from jQuery into PHP. I search for the solutions on the internet, and i came to the AJAX. Never used Ajax before, so i guess that the problem is known.

So i have the following code in “index.php”

$("#inviteForm").submit(function(e) {

e.preventDefault();
var emailVal = $("#email").val();

$.ajax({
 type: "POST",
 url: "processAjax.php",
 data: {email: emailVal},
 success: function(data) {
    alert(data);  
}
});
});

In form, i have one input box (for email) and a submit button (the method is POST).

In processAjax.php i have the following code

<?php
    $x = $_POST['email'];
    return $x;
?>

So if i’m correct, if the $.ajax function is OK, the alert box should pop up. But it doesn’t.
i’ve also tried alert(x); but it didn’t work.

Any idea what i’m doing wrong

Answer 1

Try echo $x; instead of return $x;
