Почему я не могу вставить в БД 14 строк за один раз

Question

Я использую модель MVC, фреймворк CodeIgniter. Я пытаюсь вставить 14 строк в свою БД, когда пытаюсь вставить меньше (например, 9 или 10) строк, которые работают. Я не понимаю лог c. Массив $ data принимает все 14 строк, но по какой-то причине БД не принимает его.

Это контроллер:

public function saveFinalShifts(){        
        $data = array();

        $newDate= $this->input->post('week');
        $sunday = $this->Shifts_model->getStartDate($newDate);

        $dates = array_fill(0,14,$sunday);

        $days = $this->input->post('day[]');
        $times = $this->input->post('time[]');
        $worker_names = $this->input->post('worker_name[]');

        if(is_array($dates)){
        foreach ($dates as $key => $date){
            $data[] =  array (
                'date' => $date,
                'day' => $days[$key],
                'time' => $times[$key],
                'worker_name' => $worker_names[$key],
                );
            }
        }

            $this->session->set_flashdata('success', 'Submitted!');
            $this->Shifts_model->saveFinalShifts($data);
            redirect(base_url("/Shifts/manageShifts"));

    }

Это моя модель:

public function saveFinalShifts($data) {
        $this->db->db_debug = FALSE;
        $error = NULL;
        if (!$this->db->insert_batch('final_shifts', $data)) {
            $error = $this->db->error();
        }
        return $error; 
    }

Когда я пытаюсь: echo '<pre>';print_r($data); die;

Вы можете убедитесь, что каждая из 14 строк находится в массиве $ data.

Answer 1

Попробуйте разбить массив на части.

foreach(array_chunk($data, 5) as $chunk){
     $this->db->insert_batch('final_shifts', $chunk);
}
