Question

I am facing a very strange behavior with something very basic. At the beginning of my PHP script I am testing if a POST variable called “multiplicateur” is set. I am testing this in my browser by manually entering the url. The response is telling me that the post variable is not set whereas it is set in my url. Hope someone can help. Thank you in advance for your replies. Cheers. Marc.

My url:

myurl/php/calendar.php?multiplicateur=3

My PHP:

<?php
session_start();
header('Content-Type: text/html; charset=utf-8');
require("../inc/connect.inc.php");

if(isset($_POST['multiplicateur'])){
    echo 'multiplicateur set';
}
else{
    echo 'multiplicateur not set';
}
?>

Answer 1

Use $_GET['multiplicateur'] since your variable comes from URL.

The predefined $_GET variable is used to collect values in a form with
method=”get”

Information sent from a form with the GET method is visible to
everyone (it will be displayed in the browser’s address bar) and has
limits on the amount of information to send.
