我需要检查角色是2.

$this->db->select('*');     
$this->db->from('teacher');     
$this->db->where('teacher_branch_id',$this->session->userdata('branch_id'));
$this->db->join('login','teacher.teacher_id = login.login_user_id');

$query = $this->db->get();

Answer 1

只需添加以下条件：$this->db->where('login.role', 2);

$this->db->select('*');     
$this->db->from('teacher');     
$this->db->join('login', 'teacher.teacher_id = login.login_user_id');
$this->db->where('teacher_branch_id', $this->session->userdata('branch_id'));
$this->db->where('login.role', 2);

$query = $this->db->get();
