How can you execute the script without a previous Empty check, allowing the fields to remain empty?

When executing a script without a previous Empty check, you can allow the fields to remain empty by using the isset() function to check if the variables are set before using them in the script. This way, the script will not throw any errors if the fields are empty. 

// Check if the variables are set before using them in the script
if(isset($_POST['field1']) && isset($_POST['field2'])) {
    $field1 = $_POST['field1'];
    $field2 = $_POST['field2'];
    
    // Continue with the script using the variables
    // ...
} else {
    // Handle the case where the fields are empty
    // ...
}
