Question

So I\'m new to php/the programming world and I\'m studying online and other forms and such but I couldn\'t find anything to help answer my question which is why I\'m here. Any h

Answer 1

Change related line to following: The problem is when activateBox is not empty it assings itself to $activeMain naturally.

$activeMain = isset($_POST['activateBox']);

Updated : Check this one.

function activeCheck() {
    return isset($_POST['activateBox']);
}

activeCheck();

Updated Answer Due To Updated Question : I removed session_destory if you execute that and if you have another session variable ex: user isLoggedIn it would be destroyed too. unset is OK for the purpose. Please check XSS, Sql injection attacks around the internet implement logic according to best practises, and validate/sanitize your data before process parameters into DB or etc.

    
        
    


    

    Name: 

    

    Activate: 
    
    





 $val) {
        // sanitize your inputs. @see XSS, SQL injection etc.
        // validate parameters according to your needs.
        $safeParameters[$key] = $val;
    }
    $_POST = [];
    checkIsActivated($safeParameters);
    // implement other logic,
    // save form to database etc.
}

function checkIsActivated($parameters)
{
    return !empty($parameters['activateBox']);
}
?>
