Ok, so I currently use something like this to redirect users in PHP:
//This is a simplified version, but demonstrates it's use.
function redirect($location) {
header("Location: $location");
}
An example use is redirecting a user to the login page if their session has expired, or if they try doing something that requires them to be logged in, it sends them to a 404 page.
So in PHP I can just type:
redirect("index.php/xyz");
My issue is that I now use a lot of PHP called via Ajax for things like processing forms and updating content; and this approach for redirecting doesn't work when called via Ajax.
I was planning on just changing this function to use Javascript rather than PHP.
So I'd use something like this:
function redirect($location) {
echo '<script>';
echo 'window.location.replace("'.$location.'");';
echo '</script>';
}
Which as far as I'm aware would work for both normal PHP use, and Ajax calls to PHP.
Is this bad practice? Currently using this for just Ajax calls is causing a lot of code overhead, so it makes sense to just use it for everything.
To clarify; I'm looking for a solution that would work in both normal PHP and in Ajax calls to PHP, so I can use the same code for both - rather than having to do both seperately. e.g. On submitting a form, action="dosomething.php"
, depending on the situation this file may just add a row in a database or redirect to a certain page. But this may be called either using Ajax or the normal HTML form action.
