I tried my best to figure out how to redirect someone based on the index.php?ref=[link]
, searched the internet... And couldn't figure out, here is my code :
if(isset($_GET['ref'])){
header("Location: /" . $_GET['ref']);
}else if(empty($_GET['ref'])){
header('Location: /welcome/');
}else{
header('Location: /welcome/');
}
It always executes the else if
one, even if the value in ?ref
is set. Anyone can help?
My shot - isset
determine if a variable is set and is not NULL. So if your url contains just ?ref
(not ?ref=subpage
) the condition is met, however you will be redirected to header("Location: /" . NULL);
.
Try using !empty()
instead of isset()
.
BTW: Always add exit
after header("Location: ...")
