ArgumentCountError - 参数太少答案

【问题标题】：ArgumentCountError - Too few argumentsArgumentCountError - 参数太少
【发布时间】：2020-08-04 13:25:26
【问题描述】：

我正在学习 codeigniter，我有一个页面可以更新我的数据库。但我收到这样的错误：

类型：ArgumentCountError

消息：函数 Inhouse::ubah() 的参数太少，在第 532 行的 D:\xampp\htdocs\slc\system\core\CodeIgniter.php 中传递了 0，而预期正好是 1

文件名：D:\xampp\htdocs\slc\application\controllers\Inhouse.php

行号：120

我该如何解决这个问题？这是我的代码：

控制器：

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);
    }

【问题讨论】：

你的路由定义是什么样的？

标签： php codeigniter error-handling

【解决方案1】：

得到这样的参数“$this->uri->segment(2)”

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

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

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

更多信息请点击这里Segments

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

【讨论】：

不好意思，看了Codeigniter的文档还是不太明白，我的代码还是不能运行……不介意的话，能不能详细解释一下？非常感谢

【解决方案2】：

我猜，这个错误只有在你尝试访问控制器时才发生，而没有像

这样的参数

http://localhost/slc/index.php/ubah

如果你像下面这样访问控制器，应该不会出错

http://localhost/slc/index.php/ubah/2

您可以通过将默认值设置为 $id 来解决此问题

public function ubah($id = -1){
    if($id != -1){
         //put your code here
    }else{
        show_404();
    }
}

【解决方案3】：

感谢您的所有回答，非常感谢你们帮助我修复我的代码.. 但是，我只是从我的 form_opener_multipart() 中删除“动作”；

从此：

<?= form_open_multipart('inhouse/ubah'); ?>

进入这个：

<?= form_open_multipart(); ?>

我真的不明白为什么会这样，但是现在我的程序可以运行了，你们能给我解释一下吗？我会很感激的。

还有一个问题，我的数据库表中除了“图像”列之外的其他列都可以更新。
