提交后的 Ajax 格式 - Laravel

Question

我正在做项目，我遇到了一些问题

如果我填写所有字段然后提交，则没有问题并将其保存到数据库中，但如果某些字段为空，则验证消息错误会以 JSON 格式显示在另一个页面中。

我的视图文件中没有使用任何 AJAX 代码。

这是控制器代码：

public function store(RegisterRequest $request){
    $user = User::create($request->all());
    $user->password = Hash::make($request['password']);

    if ($request->file('avatar')) {
        $image = $request->file('avatar');
        $destinationPath = base_path() . '/public/uploads/default';
        $path = time() . '_' . Str::random(10) . '.' . $image->getClientOriginalExtension();
        $image_resize = Intervention::make($image->getRealPath());
        $image_resize->resize(300, 300);
        $image_resize->save($destinationPath . '/' . $path);
    } else {
        $path = $user->avatar;
    }
    $user->avatar = $path;

    $user->save();

    return redirect()->route('admin.user.index')->with('message','User created successfully');

这里是RegisterRequest 代码：

public function rules()
{
    return [
        'name'         => 'required',
        'email'        => 'required|email|unique:users,email',
        'password'     => 'required|min:6|confirmed',
        'country_code' => 'sometimes|required',
        'phone'=>Rule::unique('users','phone')->where(function ($query) {
            $query->where('country_code', Request::get('country_code'));
        })
    ];

你能帮帮我吗？

您的错误应该可以在带有 $errors 变量的刀片文件中访问，您需要迭代并显示错误。 链接到将帮助您处理渲染部分的文档 - https://laravel.com/docs/7.x/validation#quick-displaying-the-validation-errors

显然也来自文档

If validation fails, a redirect response will be generated to send the user back to their previous location. The errors will also be flashed to the session so they are available for display. If the request was an AJAX request, a HTTP response with a 422 status code will be returned to the user including a JSON representation of the validation errors.

https://laravel.com/docs/7.x/validation#creating-form-requests

还将代码重构如下，只运行一个查询来创建用户，而不是创建然后更新。

 public function store(RegisterRequest $request){
    if ($request->hasFile('avatar')) {
        //use try catch for image conversion might be a rare case of lib failure
        try {
            $image = $request->file('avatar');
            $destinationPath = base_path() . '/public/uploads/default';
            $path = time() . '_' . Str::random(10) . '.' . $image->getClientOriginalExtension();
            $image_resize = Intervention::make($image->getRealPath());
            $image_resize->resize(300, 300);
            $image_resize->save($destinationPath . '/' . $path);
            $request->avatar = $path;
        } catch(\Exception $e){
            //handle skip or report error as per your case
        }
    }
    $request['password'] = Hash::make($request['password']);
    $user = User::create($request->all());
    return redirect()->route('admin.user.index')->with('message','User created successfully');
}
