RE: Undefined variable: admin_id - Saeed_Sikandar - 01-10-2019
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
RE: Undefined variable: admin_id - ciadmin - 01-11-2019
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.
RE: Undefined variable: admin_id - InsiteFX - 01-11-2019
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.

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);
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', $data);
And even better than that: create a model to retrieve the records from your database and use CI's query builder.
Model (Admin_model.php):
PHP Code:
public function get_admin_profile($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.
