I am using the below code for a log in screen that uses an ajax call to check the user creds via the PHP script. As you can see I have put in a console call in which works but the if call is being skipped every time.

UPDATE *** I have realised that when I send the response to the console it seems to be an empty line then the echo from the PHP script on a new line.

Ajax Call

$(document).ready(function(){
// Variable to hold request
var request;

// Bind to the submit event of our form
$("#log").submit(function(event){

// Prevent default posting of form
event.preventDefault();

// Abort any pending request
if (request) {
    request.abort();
}
// setup some local variables
var $form = $(this);

// Let's select and cache all the fields
var $inputs = $form.find("input, select, button, textarea");

// Serialize the data in the form
var serializedData = $form.serialize();

// Disable the inputs for the duration of the Ajax request.
$inputs.prop("disabled", true);

// Fire off the request
request = $.ajax({
    url: "../php/auth.php",
    type: "post",
    data: serializedData
});

request.done(function (response){

    console.log(response);

    if (response == "ok") {

        setTimeout(function() {
        return window.location.href = "../drive.php";
    }, 3000);
    }
    else {
        $('#error').html('<p class="text-center">'+response+'</p>');
    }
});

PHP Script

session_start();

include '***';

$email = clean($_POST['email']);
$pass = clean($_POST['pass']);

$_SESSION['name'] = $email;

$query = "SELECT * from users WHERE user='$email' and pass='$pass'";

$result = mysql_query($query);

$count = mysql_num_rows($result);

if ($count == 1) {
    echo 'ok';
}

else {

    echo 'Please Try Again';
};
