Checking Required Inputs

PHP has a few functions to check if the required inputs have been met. Those functions are isset, empty, and is_numeric.

Checking form to make sure its set

The isset checks to see if the field has been set and isn’t null.
Example:

$firstName = $_GET['firstName'] if(isset($firstName)){ echo "firstName field is set". "<br>"; } else{ echo "The field is not set."."<br>"; }
