Мне нужно отправить SMS всем пользователям, которые не получили его.
Я пробовал использовать сеанс, но результат тот же. Когда я печатаю_r($uid), у меня есть значение.
Контроллер:
public function sendemailsms()
{
$year = $this->db->get_where('settings', array('type' => 'running_year'))->row()->description;

$attendance_report = $this->apply_model->getnosendattendanceemail();//get result
//send sms to each one
foreach ($attendance_report as $sendemail) {
//get each result details
$uid = $sendemail->uid;
$year = $sendemail->schoolyear;
$serial = $sendemail->serial_kit;
$date = $sendemail->date;
$time = $sendemail->time;
$parent_id = $this->db->get_where('student', array('loginlogout_id', $uid))->row()->parent_id;
$parent_email = $this->db->get_where('parent', array('parent_id', $parent_id))->row()->email;
$parent_phone = $this->db->get_where('parent', array('parent_id', $parent_id))->row()->phone;
$name = $this->db->get_where('student', array('loginlogout_id' => $uid))->row()->name;
$first_name = $this->db->get_where('student', array('loginlogout_id' => $uid))->row()->first_name;
if ($serial == '~SerialNumber=AIO9192060065') {
$sms = 'Dear Rousseau International School parent, your child ' . $first_name . ' ' . $name . ' has just logged into school on ' . $date . ' at ' . $time . '';
} elseif ($serial == '~SerialNumber=AIO9192860516') {
$sms = 'Dear Rousseau International School parent, your child ' . $first_name . ' ' . $name . ' has just logged out of school ' . $date . ' at ' . $time . '';
} elseif ($serial == '~SerialNumber=AIO9192860502') {
$sms = 'Dear Rousseau International School parent, your child ' . $first_name . ' ' . $name . ' has just logged into school on ' . $date . ' at ' . $time . '';
} elseif ($serial == '~SerialNumber=3399192800019') {
$sms = 'Dear Rousseau International School parent, your child ' . $first_name . ' ' . $name . ' has just logged out of school ' . $date . ' at ' . $time . '';
} elseif ($serial == '~SerialNumber=AIO9192562080') {
$sms = 'Dear Rousseau International School parent, your child ' . $first_name . ' ' . $name . ' has just logged into school on ' . $date.' at ' . $time . '';
} elseif ($serial == '~SerialNumber=AIO9192860505') {
$sms = 'Dear Rousseau International School parent, your child ' . $first_name . ' ' . $name . ' has just logged out of school ' . $date . ' at ' . $time . '';
} else {
$sms = '';
}
// send sms
$msisdn = ['' . $parent_phone . ''];
//var_dump($msisdn);
$message = $sms;
$campaignTitle = 'Security';
$projectName = 'Rousseau';
if ($this->apply_model->attendanceemailemail($parent_email, $date, $time, $name, $first_name) == true) {
// update parameter
$update_sendemail = $this->apply_model->update_sendemail($uid, $year, $date, $time);
$this->envoi_sms($msisdn, $message, $campaignTitle, $projectName);
$update_sendemail = $this->apply_model->update_sendsms($uid, $year, $date, $time);
}
$this->load->view('backend/zktattendance');
}
}

Модель:
public function getnosendattendanceemail()
{
$this->db->select('*');
$this->db->from('attendance_report');
$this->db->where('sendemail', 0);
$this->db->where('departement_id', 2);
$this->db->where('uid !=', 0, FALSE);
$query = $this->db->get();
return $query->result();
}
