从视图传递无线电输入到控制器codeigniter4

Question

我想让所选值从视图传递到控制器，但它不工作，我尝试了一百种不同的方法来实现它，我试过用复选框代替单选，它工作了，但我不能选择产品，它只是一直选择第一个产品，使用set单选，我看到当我想选择产品时，它添加了checked=checked但它不传递给控制器。

Controller.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

只是一个尝试，但是根据CI的文档，set_radio的第一个参数应该是字段的name属性。

您已经给这个无线电组起了一个通用名称"product[]"但是你在传递"产品"。作为set_radio的第一个参数。

我在看set_radio的代码，它没有用方括号做任何魔术，所以我看不出这两个字符串匹配的任何原因。
