我遇到过一个需要更改需要验证的数据的实例,即没有提交slug时,从标题创建一个,然后验证它是唯一的。
请求有一个方法replace()
,它应该替换请求中的输入数据,但它似乎不起作用。任何人都可以对此发光吗?这就是我所拥有的:
<?php namespace Purposemedia\Pages\Http\Requests;
use Dashboard\Http\Requests\Request;
use Illuminate\Auth\Guard;
class PageRequest extends Request {
/**
* [authorize description]
* @return {[type]} [description]
*/
public function authorize( Guard $auth) {
return true;
}
/**
* [rules description]
* @return {[type]} [description]
*/
public function rules() {
// Get all data from request
$data = $this->request->all();
if( $data['slug'] === '' ) {
// if the slug is blank, create one from title data
$data['slug'] = str_slug( $data['title'], '-' );
// replace the request data with new data to validate
$this->request->replace( $data );
}
return [
'title' => 'required|min:5|max:255',
'slug' => 'min:5|max:255|alpha_dash|unique:pages,slug' . $this->getSegmentFromEnd(),
];
}
}
答案 0 :(得分:5)
您应该使用formatInput
方法执行此操作。您在此方法中返回的数据将用于验证器检查:
例如:
protected function formatInput()
{
$data = $this->all();
if( $data['slug'] === '') {
// if the slug is blank, create one from title data
$data['slug'] = str_slug( $data['title'], '-' );
}
return $data;
}
修改强>
这个方法在Laravel 2个月前(我还在使用这个版本),这很奇怪它被删除了。
将上述方法更改为:
时应该收到的效果相同public function all()
{
$data = parent::all();
if( $data['slug'] === '') {
// if the slug is blank, create one from title data
$data['slug'] = str_slug( $data['title'], '-' );
}
return $data;
}

我把整个工作TestRequest
课程放在这里。我发送空数据,因为修改后的all()
方法,即使是空数据,验证也会通过,因为我手动设置这些数据进行验证。如果我删除此all()
方法并发送空数据,我会收到错误
<?php namespace App\Http\Requests;
use App\Http\Requests\Request;
class TestRequest extends Request {
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
//
'title' => 'required|min:2|max:255',
'slug' => 'min:2|max:255'
];
}
public function response(array $errors){
dd($errors);
}
public function all(){
$data = parent::all();
$data['title'] = 'abcde';
$data['slug'] = 'abcde';
return $data;
}
}
