Query about how to hide errors if

[RedInjection]

Hello,

print $_GET['id'];

If a users goes to page.php?id=X then it will show the value but how do I make it if a user goes page.php that it shows no error as it say's its not defined?

 

Is there a simple way of doing it or do I need to write an IF function that sets id as nothing initially and if it has value then display?

Before using $_GET['id'] you need to check it exists. One way is to use the ternary operator

$id = isset($_GET['id']) ? $_GET['id']: '' /* <-- set this to the default value */;
