将无线电输入从视图传递到控制器codeigniter4

Question

我希望选定的值从视图传递到控制器，但它不起作用，我尝试了一百种不同的方法来实现它，我尝试使用复选框而不是无线电，它有效，但我不能选择产品，它只是一直选择第一个产品，使用 set radio，我看到当我想选择产品时，它添加了 checked=checked 但它没有传递给控制器​​。

控制器.php

public function form()


    {


            helper(['form']);

    
            $projectModel = new ProjectsModel();


            if ($this->request->getMethod() == 'post') {


                    $rules = [


                            'firstname' => 'required|min_length[3]|max_length[20]',
                            'lastname' => 'required|min_length[3]|max_length[20]',
                            'email' => 'required|min_length[6]|max_length[60]|valid_email|is_unique[accounts.email]',
                            'company' => 'required|min_length[3]|max_length[20]',
                            'location' => 'required|min_length[3]|max_length[20]',
                            'address' => 'required|min_length[3]|max_length[20]',
                            'product' => 'required',
                            


                    ];


                    if(!$this->validate($rules)) {
                            $data['validation'] = $this->validator;
                    }

                    else {

                            $newData = [
                                    'id' => session()->get('os_id'),
                                    'firstname' => $this->request->getVar('firstname'),
                                    'lastname' => $this->request->getVar('lastname'),
                                    'email' => $this->request->getVar('email'),
                                    'company' => $this->request->getVar('company'),
                                    'location' => $this->request->getVar('location'),
                                    'address' => $this->request->getVar('address'),
                                    'product' => $this->request->getVar('product'),

                            ];

                            $projectModel->save($newData);

                            session()->setFlashdata('success', 'Successful updated');
                            return redirect()->to('form/success');
                    }

            }


            $data['user'] = $projectModel->where('id', session()->get('id'))->first();
            
            echo view('templates/header', $data);
            echo view('form', $data);
            echo view('templates/footer', $data);
    }

Answer 1

只是一个刺，但根据CI's documentation，set_radio 的第一个参数应该是字段的名称属性。

您已为该无线电组指定了一个通用名称“product[]”，但您将“product”作为第一个参数传递给 set_radio。

我正在查看set_radio 的代码，它对方括号没有任何作用，所以我看不出这两个字符串匹配的任何原因。
