I have a form who uses the post method:

<form method="POST" action="">

And I have an input at the end of it to submit the information typed:

<input type="submit" name="okform" value="Submit"/>

Here is PHP code I tried to execute:

<?php

$bdd = new PDO('mysql:host=127.0.0.1;dbname=pure', 'root', '');

if(isset($_POST['okform'])){
    echo "yo";
} 

?>

the "yo" string shows when I click on the submit button, but when I refresh my website page the string is still shown. The $_POST['okform'] variable is set even after refreshing the webpage. Why? I don't understand.

Any thoughts?

I don't want it to be present but it is! That's the problem – Baptiste Arnaud Apr 20 '16 at 11:48

When you refresh a page with posted info it usually asks you if you want to resend the info. Try typing in the url again and hitting enter (not hitting refresh) – joshnik Apr 20 '16 at 11:49

When you refresh browser in same page, it will ask to resubmit the posted data?? – Sameer Kumar Jain Apr 20 '16 at 11:51
Thanks joshnik ! it works :) – Baptiste Arnaud Apr 20 '16 at 12:00
Just make sure once you refresh the page that you're sending a POST request and not a GET request, generraly a popup helps you to do that – Akram Saouri Apr 20 '16 at 12:27
