Try rewriting your model as below:
public function admin_options_listdisplayparent($params)
{
$condition = array(
'status !=' => '1',
'schoolId' => $params['schoolId'],
'classId' => $params['classId'],
'sectionId' => $params['sectionId']
);
$this->db->select('*');
$this->db->where($condition);
$this->db->like('studentAbsentId', '"' . $params['loginId'] . '"', 'both');
return $this->db->get('student_absent_list')->result();
}
Rewrite Controller as below:
public function getAbsentListStaff() {
date_default_timezone_set('Asia/Kolkata');
$loginType = $_POST['loginType'];
if($loginType == 1)
{
$data = array(
"schoolId" => $_POST['schoolName'],
"classId" => $_POST['className'],
"sectionId" => $_POST['sectionName'],
"loginId" =>$_POST['loginId'],
);
$absentresponse_data= $this->Android_login_model->admin_options_listdisplayparent($data);
$absentresponse = array();
foreach ($absentresponse_data as $res)
{
$row = array();
$row['studentAbsentId'] = $_POST['loginId'];
$row['studentAbsentDate'] = $res->studentAbsentDate;
$row['schoolId'] = $res->schoolId;
$row['response'] = 'absent';
$absentresponse[] = $row;
}
if(count($absentresponse) > 0){
$return = array('status'=>"Success",'data'=>$absentresponse);
echo json_encode($return);
} else {
$return = array('status'=>"Error",'description'=>"Data Not Found");
echo json_encode($return);
}
}
}
