@error 未显示 Laravel 中的错误

Question

在 Blade 中，不显示单个

@error

，但在

@foreach ($errors->all() as $error)

中显示所有错误。 这是验证

public function updateAthlete(){
        $pass = Hash::make($this->password);
        $info = Athlete::find($this->athlete_id);
    if($this->profile_photo_path){
        File::delete('storage/' . $this->filePath);
        $this->filePath = $this->profile_photo_path->store('AthletesProfile', 'public');
    }

    $this->validate([
        'name'               =>'required|max:70|min:3',
        'name_fa'            =>'required|max:70|min:3',
        'name_pa'            =>'required|max:70|min:3',
    ]);
    
    $info->update([
        'name'               => $this->name,
        'name_fa'            => $this->name_fa,
        'name_pa'            => $this->name_pa,
   ]);

   session()->flash('updated', 'Post successfully updated.');

}

这就是表格

<div class="form-group form-group-default">
    <label>Name in Farsi</label>
    <input type="text" class="form-control" dir="RTL" wire:model="name_fa">
  @error('name_fa') <span class="error" style="color:red">{{ $message }}</span> @enderror
</div>

它没有在控制台中显示任何错误，或者它与样式无关

Answer 1

你不能像这样使用验证功能。

您需要传递一个 Request 实例才能使其工作:

public function updateAthlete(Request $request) 
{
    // .....

    $request->validate([
        'name'               =>'required|max:70|min:3',
        'name_fa'            =>'required|max:70|min:3',
        'name_pa'            =>'required|max:70|min:3',
    ]);

    // or :

    $this->validate($request, [
        'name'               =>'required|max:70|min:3',
        'name_fa'            =>'required|max:70|min:3',
        'name_pa'            =>'required|max:70|min:3',
    ]);
}

实现此目的的一种方法是通过

php artisan make:request UpdateAthleteRequest

创建表单请求验证，该文件将位于

app\Http\Requests

文件夹中，并将您的规则添加到 Rules() 方法中。

public function rules()
{
    return [
        'name'               =>'required|max:70|min:3',
        'name_fa'            =>'required|max:70|min:3',
        'name_pa'            =>'required|max:70|min:3',
    ];
}

在您的控制器中，使用该文件并：

public function updateAthlete(UpdateAthleteRequest $request){
$pass = Hash::make($this->password);
        $info = Athlete::find($this->athlete_id);
    if($this->profile_photo_path){
        File::delete('storage/' . $this->filePath);
        $this->filePath = $this->profile_photo_path->store('AthletesProfile', 'public');
    }
    
    $info->update($request->validated());

   session()->flash('updated', 'Post successfully updated.');
}

完成后您必须重定向到视图文件。就目前而言，您的访问者在更新数据后将看到一个空白页面。

`$data = array_merge($data, [
    'name'               => $this->name,
    'name_fa'            => $this->name_fa,
    'name_pa'            => $this->name_pa,

]）；`

`$validateData = array_merge($validateData, [
    'name'               =>'required|max:70|min:3',
    'name_fa'            =>'required|max:70|min:3',
    'name_pa'            =>'required|max:70|min:3',
]);`

`$validation = Validator::make($data, $validateData)->validate();`

`$info->update($validation);`

`session()->flash('updated', 'Post successfully updated.');`
