我正在学习codeigniter，我有一个页面可以更新我的数据库。但是我得到了一个这样的错误：
类型：ArgumentCountError
消息：函数Inhouse:：ubah((的参数太少，在第532行的D:\examplep\htdocs\slc\system\core\CodeIgniter.php中传递了0，并且正好需要1个
文件名：D:\examplep\htdocs\slc\application\controllers\Inhouse.php
线路编号：120
如何解决此问题？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);
}

获取这样的参数"$this->uri->segment(2(">
exp:-htts://localhost/ci/50/60
$this->uri->segment(2(//O/P50
$this->uri->segment(3(//O/p 60
有关更多信息，请访问此处分段
public function ubah(){
$this->uri->segment(2);
}
我想，只有当你试图访问没有之类参数的controler时，才会发生这个错误
http://localhost/slc/index.php/ubah
如果你像下面这样访问控制器，就不应该有错误
http://localhost/slc/index.php/ubah/2
您可以通过将默认值设置为$id来解决此问题
public function ubah($id = -1){
if($id != -1){
//put your code here
}else{
show_404();
}
}
谢谢你们的回答，我真的很感谢你们帮我修复代码。。但是，我只是从form_opener_multipart((中删除了"action"；
由此：
<?= form_open_multipart('inhouse/ubah'); ?>
进入：
<?= form_open_multipart(); ?>
我真的不明白为什么会这样，但现在我的程序可以运行了，你们能向我解释一下吗？我真的很感激。
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。
