Yes sir but I define this variable in admin-profile. Should I define that variable again in a controller of this view page or not

I don't see $admin_id defined there. I see an array, where the key 'admin_id' references some variable $admin_id, which must be defined elsewhere or you will get an undefined variable error message. Hmmmmm.

For one you should not be running database queries in the view that should be done in the controller.

Then assign the result to the $data array pass it to the view then loop through it.

What did you Try? What did you Get? What did you Expect?

Alright thanks

Try to add
if (!empty($admin_id)) {
// your code
}

Make sure you have an array key named 'admin_id' in your controller, and pass the array to the view.

Controller:

PHP Code:

$data['admin_id'] = 123;
$data['other_stuff'] = 'Other stuff';
$this->load->view('admins\admin-profile', $data); 


This way, the $admin_id variable is also available in your view.

Even better: get the $profile_info records in your controller instead of the view.
Controller:

PHP Code:

$data['profile_info'] = $this->db->get_where('admin' , array('admin_id' => $admin_id))->result_array();
$this->load->view('admins\admin-profile', $data); 


Now, in your view, $profile_info is an array that you can loop through.

And even better than that: create a model to retrieve the records from your database and use CI's query builder.
Model (Admin_model.php):

PHP Code:

public function get_admin_profile($admin_id)
{
   $query = $this->db->where('admin_id', $admin_id)->get('admin');
   if ($query->num_rows() == 0) {
     return FALSE;
   else {
     return query->result_array();
   }
} 


Controller:

PHP Code:

$this->load->model('admin_model');
$data['profile_info'] = $this->admin_model->get_admin_profile(123);
$this->load->view('admins\admin-profile', $data); 


This will keep your controllers lean. Load the model in any controller where you need the admin profile.
