Answer 1

I've created query which will return the data of users with designation_id 2 and 3, also which don't have attendance_status 3 and 4
Your controller code is fine -
$date = date('Y-m-d');
$data['assign_user'] = $this->Project_model->get_manager_cordinator_users($date);
Just change your model code with below one -
public function get_manager_cordinator_users($date)
{
$this->db->select( 'tbl_users.user_id, tbl_users.username,tbl_account_details.designations_id, tbl_attendance.date_in, tbl_attendance.attendance_status' );
$this->db->from( 'tbl_users' );
$this->db->join( 'tbl_account_details', 'tbl_account_details.user_id = tbl_users.user_id' );
$this->db->join( 'tbl_attendance', 'tbl_attendance.user_id = tbl_users.user_id' );
$this->db->where( 'tbl_attendance.date_in', $date );
$this->db->where('tbl_users.banned', 0);
$this->db->where('tbl_users.activated', 1);
$this->db->where_in( 'tbl_account_details.designations_id', array( '2', '3' ) );
$this->db->where_not_in( 'tbl_attendance.attendance_status', array( '3', '4' ) );
return $this->db->get()->result();
}
It will provide you required user data.

Answer 2

now i got it
public function get_manager_cordinator_users()
{
$date=date('Y-m-d');
$this->db->select('tbl_users.*');
$this->db->join('tbl_account_details', 'tbl_users.user_id = tbl_account_details.user_id', 'left');
$this->db->where('tbl_users.user_id NOT IN(SELECT user_id FROM tbl_attendance WHERE tbl_attendance.date_in= "'.$date.'" AND tbl_attendance.attendance_status IN (3,4) ) ');
$this->db->where_in( 'tbl_account_details.designations_id', array( '2','3' ) );
$this->db->where('tbl_users.banned', 0);
$this->db->where('tbl_users.activated', 1);
$query_result = $this->db->get('tbl_users');
$result = $query_result->result();
return $result;
}

Answer 3

use this
$this->db->select('tbl_account_details.*', FALSE);
$this->db->select('tbl_users.*');
$this->db->join('tbl_users', 'tbl_users.user_id = tbl_account_details.user_id', 'left');
$this->db->where('(designations_id=2 or designations_id=3 )');
$this->db->where('tbl_users.user_id NOT IN(SELECT user_id FROM tbl_attendance WHERE tbl_attendance.date_in='.$date.' && attendance_status=3 OR attendance_status=4 )');
$query_result = $this->db->get('tbl_users');
$result = $query_result->result();
return $result;

Answer 4

$this->db->select('*)->from('tbl_users')->where('tbl_attendance.attendance_status <= 2')->where('tbl_attendance.data_in =',date('Y-m-d'))->join('tbl_attendance','tbl_attendance.user_id = 'tbl_users.user_id ','left')->get()->result();
