如何验证更新 laravel 中的唯一电子邮件和唯一名称?

how validate unique email and unique name in update laravel?

这是我的代码:

public function update(User $user)
{
    $this->validate(request(), [
        'name'   => 'required|min:3|max:50|unique:users,name,' . $user->id,
        'email'  => 'required|email|max:255|unique:users,email,' . $user->id,
        'origin' => 'max:50',
        'about'  => 'max:5000',
    ]);
    $user = User::find($user);
    $user->name = request('name');
    $user->original = request('origin');
    $user->email = request('email');
    $user->about = request('about');
    $user->save();

    return back();
}

我收到这个错误:

Illuminate\Database\QueryException
SQLSTATE[HY093]: Invalid parameter number (SQL: select * from .... ?))

验证函数期望第一个参数作为请求输入数组而不是请求对象。以下代码可以正常工作。

$this->validate (request()->all(), $rules)

您还可以为验证消息传递第三个参数。

错误可能源于$user = User::find($user);

由于您正在使用 Route model binding,因此您不需要再次加载 User

public function update(User $user)
{
    $this->validate(request(), [
        'name'   => 'required|min:3|max:50|unique:users,name,' . $user->id,
        'email'  => 'required|email|max:255|unique:users,email,' . $user->id,
        'origin' => 'max:50',
        'about'  => 'max:5000',
    ]);

    $user->name = request('name');
    $user->original = request('origin');
    $user->email = request('email');
    $user->about = request('about');
    $user->save();

    return back();
}
