RedInjection Posted November 6, 2015 Share Posted November 6, 2015 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?

Solution Ch0cu3r Posted November 6, 2015 Solution Share Posted November 6, 2015 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 */; Quote Link to comment Share on other sites More sharing options...
