}
I got this error: "Uncaught PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'user_id' cannot be null
You got error in your code
I dont think you mean to access value from the $data
array$this->db->bind(':user_id', $data[$user_id]);
You probably want to use $user_id value directly$this->db->bind(':user_id', $user_id);
