$_GET and URL parameters

[cheesybiscuits]

I got two links with a parameter with a value. When I click either link it will send me to the same challenge.php page, I'm wanting to find the value of the parameter and display the page according to what value the parameter has in the url.

This script doesn't seem to be working.

<a href="http://www.site.com/challenge.php?id=1">Complete Challenge 1</a>
<a href="http://www.site.com/challenge.php?id=2">Complete Challenge 2</a>

$id = $_GET['id'];
if ($id=1) {
        echo "This is challenge 1 completed";
} elseif ($id=2) {
echo "This is challenge 2 completed";
else {
echo "The URL parameters didn't work";
}

Any help would be appreciated thanks.

A single equals is an assignment operator. You need two equals ( == ) in your if/elseif statement.

When comparing two values, use the comparison operator == not the assignment operator =. Your code should looks like this.

 

$id = (int)$_GET['id'];
if ($id == 1) {
        echo "This is challenge 1 completed";
} elseif ($id == 2) {
echo "This is challenge 2 completed";
else {
echo "The URL parameters didn't work";
}
