I am trying to refresh a PHP page on form submit only once. My issue is that I have multiple form elements on this page each updating something or the other. So I click on one of the form submit and I want to refresh the page only once, but using the code below:
echo '<meta http-equiv="Refresh" content="0;' . $page . '">';
the page keeps on reloading itself again and again. Is there a way I can get out of this loop without affecting other form elements?
You can submit your forms with the POST method. Then detect the POST request, and meta refresh with GET method (which is the default).
Detect the POST like this:
if ( $_SERVER['REQUEST_METHOD'] == 'POST' ) {}
See these questions:
Detecting request type in PHP (GET, POST, PUT or DELETE)
How to detect if $_POST is set?
Look into RESTful architecture on when to use POST vs. GET:
