Codeigniter - проверка формы выполняется, но не отображает ошибки при FALSE

Question

Я столкнулся с ситуацией с проверкой формы. Что-то такое простое, я не могу понять, в чем моя проблема, и довольно долго искал в Интернете. Моя форма, если она оставлена ​​пустой, должна выдавать ошибки через form_error для каждого поля, если form_validation возвращает FALSE. Однако ничего не происходит. Когда форма заполнена полностью, она отлично вставляется в БД. Я застрял и, кажется, не могу понять, какое решение. Я думаю, что в коде где-то есть орфографическая ошибка или форма неправильно спроектирована.

Вот мой контроллер:

function create_job()
    {
        // validate each form field
        $this->form_validation->set_rules('repair_order', 'Repair Order', 'required');
        $this->form_validation->set_rules('first_name', 'First Name', 'trim|required');
        $this->form_validation->set_rules('last_name', 'Last Name', 'trim|required');
        $this->form_validation->set_rules('phone', 'Phone', 'required');
        $this->form_validation->set_rules('vin', 'VIN', 'trim|required');
        $this->form_validation->set_rules('year', 'Vehicle Year', 'trim|required|min_length[4]');
        $this->form_validation->set_rules('make', 'Vehicle Make', 'required');
        $this->form_validation->set_rules('model', 'Vehicle Model', 'required');
        $this->form_validation->set_rules('start_date', 'Start Date', 'required');
        $this->form_validation->set_rules('promise_date', 'Promise Date', 'required');
        $this->form_validation->set_rules('body_hours', 'Body Labor Hours', 'required');
        $this->form_validation->set_rules('paint_hours', 'Paint Labor Hours', 'required');
        $this->form_validation->set_rules('body_tech', 'Body Technician', 'required');
        $this->form_validation->set_rules('paint_tech', 'Paint Technician', 'required');

            if($this->form_validation->run())
            {
                $data = array(
                'repair_order'      => $this->input->post('repair_order'),
                'first_name'        => $this->input->post('first_name'),
                'last_name'         => $this->input->post('last_name'),
                'address'           => $this->input->post('address'),
                'city'              => $this->input->post('city'),
                'state'             => $this->input->post('state'),
                'zip_code'          => $this->input->post('zip_code'),
                'phone'             => $this->input->post('phone'),
                'vin'               => $this->input->post('vin'),
                'year'              => $this->input->post('year'),
                'make'              => $this->input->post('make'),
                'model'             => $this->input->post('model'),
                'start_date'        => $this->input->post('start_date'),
                'promise_date'      => $this->input->post('promise_date'),
                'body_hours'        => $this->input->post('body_hours'),
                'paint_hours'       => $this->input->post('paint_hours'),
                'insurance'         => $this->input->post('insurance'),
                'body_tech'         => $this->input->post('body_tech'),
                'paint_tech'        => $this->input->post('paint_tech')
                );
                $this->db->insert('jobs', $data);

                $this->session->set_flashdata("success", "New job has been successfully created.");
                redirect('main');
            }
            else
            {
                redirect('jobs/new');
            }
    }

Я новичок в CodeIgniter, просто пытаюсь научиться. Я был бы очень признателен, если бы кто-нибудь мог понять, в чем заключается проблема, и помочь мне найти ответ.

Answer 1

Ваше перенаправление не будет передавать сообщения form_error. Вам нужно загрузить представление (вашу форму), чтобы вызвать form_error, используя $this->load->view()

Попробуйте это:

function create_job()
{
    // validate each form field
    $this->form_validation->set_rules('repair_order', 'Repair Order', 'required');
    $this->form_validation->set_rules('first_name', 'First Name', 'trim|required');
    $this->form_validation->set_rules('last_name', 'Last Name', 'trim|required');
    $this->form_validation->set_rules('phone', 'Phone', 'required');
    $this->form_validation->set_rules('vin', 'VIN', 'trim|required');
    $this->form_validation->set_rules('year', 'Vehicle Year', 'trim|required|min_length[4]');
    $this->form_validation->set_rules('make', 'Vehicle Make', 'required');
    $this->form_validation->set_rules('model', 'Vehicle Model', 'required');
    $this->form_validation->set_rules('start_date', 'Start Date', 'required');
    $this->form_validation->set_rules('promise_date', 'Promise Date', 'required');
    $this->form_validation->set_rules('body_hours', 'Body Labor Hours', 'required');
    $this->form_validation->set_rules('paint_hours', 'Paint Labor Hours', 'required');
    $this->form_validation->set_rules('body_tech', 'Body Technician', 'required');
    $this->form_validation->set_rules('paint_tech', 'Paint Technician', 'required');

        if($this->form_validation->run())
        {
            $data = array(
            'repair_order'      => $this->input->post('repair_order'),
            'first_name'        => $this->input->post('first_name'),
            'last_name'         => $this->input->post('last_name'),
            'address'           => $this->input->post('address'),
            'city'              => $this->input->post('city'),
            'state'             => $this->input->post('state'),
            'zip_code'          => $this->input->post('zip_code'),
            'phone'             => $this->input->post('phone'),
            'vin'               => $this->input->post('vin'),
            'year'              => $this->input->post('year'),
            'make'              => $this->input->post('make'),
            'model'             => $this->input->post('model'),
            'start_date'        => $this->input->post('start_date'),
            'promise_date'      => $this->input->post('promise_date'),
            'body_hours'        => $this->input->post('body_hours'),
            'paint_hours'       => $this->input->post('paint_hours'),
            'insurance'         => $this->input->post('insurance'),
            'body_tech'         => $this->input->post('body_tech'),
            'paint_tech'        => $this->input->post('paint_tech')
            );
            $this->db->insert('jobs', $data);

            $this->session->set_flashdata("success", "New job has been successfully created.");
            redirect('main');
        }
        else
        {
            $this->load->view('yournewjobform');
        }
}
