Error is not CI related, it is a general PHP error.
Code:
function control_record_of_user($id_record,$user_id){
$device = $this->get_Device($id_record) ;//get record
//here run print_r($device); die(); to check the what is inside of the $device variable.
// you can update codes below like this: return $device->id_user==$user_id;
if($device->id_user==$user_id){
return TRUE;
}else{
return FALSE;
}
}
In your method you are not checking if the get_Device method returning an
object, if there is not record with that $id_record it might return NULL. Or as error says even if it returns something it is type maybe
not an object but
array. By running print_r($device) check what is inside of it.
Also, I suggest to not run separate method to check if the record belongs to the user. Instead, build your SQL query with the condition for example:
DELETE from records
WHERE record_id = 2 and id_user = 56
Also, you can build DB constraints (Foreign key, DB relations).
For example, you have users and users have records. In DB you can build a constraint saying if a user is deleted then delete its records also.
This way you don't have to run separate queries, and use transactions.
