php - ArgumentCountError-参数太少

标签 php codeigniter error-handling

我只是在学习codeigniter，并且有一个页面可以更新我的数据库。但我收到这样的错误:

Type: ArgumentCountError

Message: Too few arguments to function Inhouse::ubah(), 0 passed in D:\xampp\htdocs\slc\system\core\CodeIgniter.php on line 532 and exactly 1 expected

Filename: D:\xampp\htdocs\slc\application\controllers\Inhouse.php

Line Number: 120



我该如何解决这个问题？这是我的代码:

Controller :
public function ubah($id)
    {
        $data['title'] = 'Change Form - Data IHT Program';
        $data['inhouse'] = $this->Inhouse_model->getInhouseById($id);
        $data['user'] = $this->db->get_where('user', ['email' => $this->session->userdata('email')])->row_array();

        $this->form_validation->set_rules('title', 'Title', 'required');
        $this->form_validation->set_rules('subtitle', 'Subtitle', 'required');
        $this->form_validation->set_rules('overview', 'Overview', 'required');
        $this->form_validation->set_rules('goals', 'Goals', 'required');
        $this->form_validation->set_rules('agenda1', 'Agenda 01', 'required');
        $this->form_validation->set_rules('agenda2', 'Agenda 02', 'required');
        $this->form_validation->set_rules('agenda3', 'Agenda 03', 'required');
        $this->form_validation->set_rules('agenda4', 'Agenda 04', 'required');
        $this->form_validation->set_rules('agenda5', 'Agenda 05', 'required');
        $this->form_validation->set_rules('agenda6', 'Agenda 06', 'required');
        $this->form_validation->set_rules('agenda7', 'Agenda 07', 'required');
        $this->form_validation->set_rules('agenda8', 'Agenda 08', 'required');
        $this->form_validation->set_rules('trainer', 'Trainer', 'required');

        if ($this->form_validation->run() == FALSE) {
            if (!$this->session->userdata('email')) {
                $this->load->view('templates/header', $data);
            } else {
                $this->load->view('templates/login_header', $data);
            }
            $this->load->view('inhouse/ubah', $data);
            $this->load->view('templates/footer');
        } else {
            // cek jika ada gampar yg diupload
            $upload_image = $_FILES['image']['name'];

            if ($upload_image) {
                $config['allowed_types'] = 'gif|jpg|png';
                $config['max_size'] = '5048';
                $config['upload_path'] = './assets/img/inhouse/';

                $this->load->library('upload', $config);

                if ($this->upload->do_upload('image')) {
                    $old_image = $data['inhouse']['image'];
                    if ($old_image != 'default.jpg') {
                        unlink(FCPATH . 'assets/img/inhouse/' . $old_image);
                    } else {
                        $new_image = $this->upload->data('file_name');
                        $this->db->set('image', $new_image);
                    }
                } else {
                    echo $this->upload->display_errors();
                }
            }

            $this->db->set('image', $new_image);
            $this->db->where('id', $id);
            $this->db->update('inhouse', $data);

            $this->Inhouse_model->ubahInhouseProgram();
            $this->session->set_flashdata('flash', 'Diubah!');
            redirect('admin/product');
        }
    }

型号:
public function ubahInhouseProgram()
    {
        $data = [
            "image" => $this->input->post('image', true),
            "title" => $this->input->post('title', true),
            "subtitle" => $this->input->post('subtitle', true),
            "overview" => $this->input->post('overview', true),
            "goals" => $this->input->post('goals', true),
            "agenda1" => $this->input->post('agenda1', true),
            "agenda2" => $this->input->post('agenda2', true),
            "agenda3" => $this->input->post('agenda3', true),
            "agenda4" => $this->input->post('agenda4', true),
            "agenda5" => $this->input->post('agenda5', true),
            "agenda6" => $this->input->post('agenda6', true),
            "agenda7" => $this->input->post('agenda7', true),
            "agenda8" => $this->input->post('agenda8', true),
            "trainer" => $this->input->post('trainer', true)
        ];
        $this->db->where('id', $this->input->post('id'));
        $this->db->update('inhouse', $data);
    }

最佳答案

像这样获取参数“$ this-> uri-> segment(2)”

exp:-htts://localhost/ci/50/60

$ this-> uri-> segment(2)//O/P 50

$ this-> uri-> segment(3)//O/P 60

欲了解更多信息，请点击这里Segments

public function ubah(){
 $this->uri->segment(2);
}
