How to refresh a page only ONCE after form submit in php?

Question

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?

Why do you need to refresh? The form submission should re-process the page.. — chris85, Jul 15 '16 at 11:11
can you post your form here ? and why do you want to reload ? are you loading fields like states after selecting country ? — Mickey, Jul 15 '16 at 11:14
Then don't submit form in that way, I recommend you to use AJAX for those calls. 'meta http-equiv="Refresh"' is not a way at all. It will load page in a time interval irrespective of your inputs. Instead, you can use 'onChange' in your select — Mickey, Jul 15 '16 at 11:23

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:

Look into RESTful architecture on when to use POST vs. GET:
