php validation laravel-5

Php 将表单验证程序传递到控制器'；的构造函数导致控制器无法正确执行,php,validation,laravel-5,controllers,laravel-validation,Php,Validation,Laravel 5,Controllers,Laravel Validation,我仍在学习拉维5，并且正在学习拉维5。我一直在学习这一课，我发现这很有帮助，但是我发现代码库需要做一些细微的更改，以适应视频课程录制后对Laravel的更改。我想知道我的问题是否是由于某些必要的特征、说明或惯例而取代了本课程 当我单击“配置文件”链接时，页面会明显刷新，但我不会导航到“显示配置文件”页面 这是我的app/Http/routes.php <?php /* |-----------------------------------------------------------

我可以登录和注销没有问题。配置文件管理的一切都会发生，我已经隔离了作为配置文件控制器的问题：：\u构造（ProfileForm$ProfileForm）。当我从构造函数中删除参数时，ProfilesController将执行，但是我不再提供基于表单请求的验证

我删除了该参数以进入Show Profile页面，然后在页面内重新安装它一次，以查看它对单击上面Show.blade.php中的“Edit Profile”链接的影响。网站响应失败，出现“重定向您太多次”错误

我使用PHP版本5.5.12和Apache版本2.4.9运行WAMPServer

有人能帮忙吗？

这里的问题是，您不应该将表单请求类作为控制器的构造函数参数，因为一旦解决了此类对象，就会触发验证

因此，您应该从
profilescoontroller
类中删除构造函数，并修改此控制器的
update
方法，如下所示：

public function update(ProfileForm $request,$username)
{
    $user = User::with('profile.country')->whereName($username)->firstOrFail();
    /**
     * Restricting input data to the values posted from the form
     */
    $input = $request->only('address1', 'address2', 'city', 'postcode');

    $user->profile->fill($input)->save();

    return view('profiles.show')->withUser($user);

}

}
构造函数会在所有操作中自动启动，在这些操作中，您需要获取或发布参数。但它们只需要在中更新操作

看到我的答案了吗？它有什么区别？你的答案是正确的，但我认为你的例子显示了一个错误。变量是结束你的->公共功能更新（$username，ProfileForm$request）我的->公共功能更新（ProfileForm$request，$username）你看到我的答案了吗？它有什么区别？你的答案是正确的，但我认为你的例子显示了一个错误。变量是结束你的->公共功能更新（$username，ProfileForm$request）我的->公共功能更新（$ProfileForm request，$username）
