Doh!

Fatal error: Call to a member function executeQuery() on a non-object in /home/phpsauce/public_html/sources/authClass.php on line 65

PHP Code:


		
			
    function checkSession() {

        @session_start();

        $username = $_SESSION['username'];

         $session = session_id();

        $ip = $_SERVER['REMOTE_ADDR'];

        $query = "SELECT * FROM users WHERE (username = '$username') AND (session = '$session') AND (ip = '$ip')";

        $result = $connect->executeQuery($query) or die('Auth Subsystem Error');



        if (mysqli_num_rows($result) > 0 ) {

            return true;

        } else {

            $this->session_defaults();

            return false;

        }

    }

Line 65:

PHP Code:


		
			
$result = $connect->executeQuery($query) or die('Auth Subsystem Error');

What am I doing wrong? :-/

And if it helps, here is the executeQuery code:

PHP Code:


		
			
    public function executeQuery($query) {
        if($res = mysqli_query($this->link,$query)) {
            return $res;
        }
        else {
            $this->dbError = mysqli_error($this->link);
            return false;
        }
    }

The variable $connect (local to the scope of that function) is not defined and undefined variables don't have methods attached. Which class has an executeQuery method and where is it instantiated?

Edit: Are these both defined in the same class?

Thanks for your fast reply :)

PHP Code:


		
			
    function __construct() {
        @session_start();
        require_once( SOURCES_PATH . 'dbClass.php' );
        $connect = new dbClass();
        $connect->dbConnect( 'localhost', 'user', 'pass', 'database' );

        @session_start();

        if (!isset($_SESSION['logged'])) {
            $this->session_defaults();  
        }

    }

This is from the authClass. dbClass contains the executeQuery function.

The $connect variable is only available within the __construct. The simplest workaround would be to use $this->connect wherever you have just $connect right now.

Ah! Starting to understand OOP a bit better now, thanks Salathe! ^^
