I have a wrapper that is displaying on the whole screen and I want it so if I enter ?display=0
into my URL that the wrapper will disappear with PHP or JavaScript. I’ve been searching for 2 hours and these are the things I found:
$host = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; if($host == 'http://example.com/home?display=0') { ... }
if(location.hash == "") { ... }
if($_GET['display' == 1]) { ... }
But none of them worked so is there any way to do this in PHP or JavaScript?

You were close in what you were doing.
if($_GET['display' == 1]) { ... } ^ ^
You have a rather serious typo, you misplaced the closing bracket of the $_GET array.
Changing the above to this should yield some results;
if($_GET['display'] == 1 ) { ... }
Although I personally would do a check to see if “display” is set at all, so you’d end up with something like;
if ( isset( $_GET['display'] ) ) { // The URL included a ?display= parameter if ( $_GET['display'] == 1 ) { ... } }else{ // Default behaviour if there is no ?display= in the URL }
If you don’t do a check like this, PHP will throw an “Undefined index: display” error if someone opens the page without the ?display=
bit added to the URL.
