Question

What is the neat soluton to check user group level to do certain tasks

Groups: 2 Admin, 3 Moderators, 4 Process Orders

Let assume data['user']['group_id'] is 3

I came up with this Solution.

Solution 1:

$allowGroup = array(2, 3, 4);
if (in_array($this->data['user']['group_id'], $allowGroup)) {
    //Show a list of records
    if ($this->data['user']['group_id'] == 2) {
      //Show buttons to delete records (only admin can do this)
     }
}

Solution 2:

if (($this->data['user']['group_id'] == 3) || ($this->data['user']['group_id'] == 4)) {
      //Member can do this action..
}

Answer 1

A slightly more efficient, but less readable method would be to specify your “allowed” levels as the array keys. Then it’s a simple array lookup, without having to call in_array(), which would do a (more) expensive loop:

$rawAllow = array(2,3,4);
$allowed = array_flip($rawAllow);

if (isset($allowed[$this->data['user']['group_id']])) {
   ... this user is allowed to perform the action...
}
