Get Parameter from URL using PHP

Question

I have a url:

domain.com/?city=newyork&postback=test

I am currently successfully passing the postback parameter using the PHP below. However, I can not figure out how to also pass the city parameter.

<?php session_start(); 

if(isset($_SESSION['postback'])) {
    if($_GET['postback'] == "") {
        header ("Location: qualify-step2.php?postback=".$_SESSION['postback']);
        }
    }

 ?>

Can someone please help me edit the code successfully? Any suggestions are greatly appreciated.

Use the superglobal $_GET for accessing those variables. This is pretty basic. — Devon Bessemer

You should use the $_GET superglobal to get params from url... In your case $_GET['city'] holds the value newyork and $_GET['postback'] holds the value test.

You mean like this

<?php session_start(); 

if(isset($_SESSION['postback'])) {
    if($_GET['postback'] == "") {
        header ("Location: qualify-step2.php?postback=".$_SESSION['postback']."&city=".$_SESSION['city']);
        }
    }

?>

Did you just add &city=".$_SESSION['city'] to the end of URL ? Why did you do that? your condition is if($_GET['postback'] == ""), it is mean, this parameter is null.

I'm completely lost with this stuff, tried hacking with the code but I was missing the "." at the end of .$_SESSION['postback']

For geting parameter from URL, you should use $_GET['param'];.

Note: In here, You should use Get method for sending data.
