Question

I have a model class that looks likes the following

function block_user()
{

  function is_in_blocked_list()
   {
     //line number 137...

   }
  function power_block()
  {
    is_in_blocked_list()  // doing some operations


  }

 if (condition)
 {
 power_block();
 }

}

But i am getting an error on is_in_blocked_list()

that is

Using $this when not in object context in C:\wamp\www\pname\application\models\admin\admin_user.php on line 137

Line 137 says that

$qry = "SELECT a FROM tblC WHERE username=?";
            $qry = $this->db->query($qry,array($userName));

i am new to php and codeigniter,how can i fix this problem ?

INFO :THANKS FOR THE DOWNVOTE [BUT YOUR ANSWER IS WORST :)]

Answer 1

Your functions need to ask on what they operate:

function block_user(Controller $controller)
{
    function is_in_blocked_list(Controller $controller)
    {
        //line number 137...
        $controller->.... (not $this->...)
    }
    function power_block(Controller $controller)
    {
        is_in_blocked_list($controller)  // doing some operations
    }
    if (condition)
    {
        power_block($controller);
    }
}

Replace the Controller type with the type of controller they should operate on, the general one in CI is called CI_Controller IIRC.

I would not consider this a good solution, but it probably shows the picture what you’re conceptually doing.
