How to send in a get a hexadecimal color?

Question

For example: index.php?color=#c2c2c2

echo $_GET['color'];

This possibly will not work, so how?

Answer 1

URL encode what you send in. #, when url encoded, is %23.

On the receiving side, you just need to do:

$color = urldecode($_GET['color']);

To URL encode in javascript:

var color = encodeURIComponent("#c2c2c2");
