Question

Im having a issue with my code i am working on. I am trying to get a include loaded depending on the status of the user (if they paid and if they have a invalid email. The NULL value is being pulled form the database however it only sends to the entermail.php

Here is my code does anyone see whats wrong?

 function is_premium() {
        $premium_query = mysql_query("SELECT 'authLevel' FROM 'users' WHERE 'fbID' ='".$userId."'");
        $premium = mysql_query($premium_query);
        if ($premium=='1') {
            return true; 
        } else {
            return false;
        }
     }

     function valid_email() {
        $validemail_query = mysql_query("SELECT 'parentEmailOne' FROM 'users' WHERE 'fbID' ='".$userId."'");
        $validemail = mysql_query($validemail_query);
        if ($validemail != 'NULL') {
            return true;
        } else {
            return false;
            }
     }

      if (!empty($session) && is_premium() && valid_email()) {
        include 'indexPremium';

      } else if (!empty($session) && valid_email()) {
        include 'entermail.php';    

     } else if (!empty($session)) {
        include 'indexLoggedIn.php';

    }else{
        include 'indexNotLogged.php'; 
    }

You’re not actually storing the string “NULL” in the database are you? Null is not the same as string “NULL” — perhaps you want something like:

    if (empty($validemail)) {
        return false;
    } else {
        return true;
    }

Or shorter:

return !empty($validemail);
