Php 如何在Laravel中注册后将用户重定向到上一个URL

使用Laravel 5.6中的内置身份验证系统，我的网站上有多个页面，需要用户注册或登录以执行购买等操作

我让我的登录重定向回用户登录前所在的上一页，但似乎无法使其与注册一起工作

我正在寻找的示例：

//protected $redirectTo = '/'; (Originally Returning Back To Home)

//WHAT I'M USING NOW TO TRY AND REDIRECT BACK TO PREVIOUS PAGE

    protected function redirectTo()
    {
    return url()->previous();
    }

// Guards/Redirects user to home if logged in and tries to access register page again.

    public function __construct()
    {
        $this->middleware('guest');
    } 


// If users email exists in my transaction database, I show them a Thank you message upon registering. And Still want to redirect them back to previous page.

    public function registered($request, $user) {
        $where = [
            ['customer_email', $user->email],
            ['user_id', null],
        ];

        if (Transaction::where($where)->exists()) {
            Transaction::where($where)->update(['user_id' => $user->id]);

            return url()->previous()
                ->with('success', 'Thank you for your previous transaction! Go to your Profile to review your transaction history.');
        }
    }

用户从第X页单击“注册”

用户进入注册页面

然后，用户被重定向回第X页，而不是主页

用户总是被重定向回以前所在的页面

这是我的RegisterController.php:

//protected $redirectTo = '/'; (Originally Returning Back To Home)

//WHAT I'M USING NOW TO TRY AND REDIRECT BACK TO PREVIOUS PAGE

    protected function redirectTo()
    {
    return url()->previous();
    }

// Guards/Redirects user to home if logged in and tries to access register page again.

    public function __construct()
    {
        $this->middleware('guest');
    } 


// If users email exists in my transaction database, I show them a Thank you message upon registering. And Still want to redirect them back to previous page.

    public function registered($request, $user) {
        $where = [
            ['customer_email', $user->email],
            ['user_id', null],
        ];

        if (Transaction::where($where)->exists()) {
            Transaction::where($where)->update(['user_id' => $user->id]);

            return url()->previous()
                ->with('success', 'Thank you for your previous transaction! Go to your Profile to review your transaction history.');
        }
    }

下面是我如何在使用登录控制器时得到这个结果的，但是没有使用注册控制器

public function showLoginForm()
{
    if (session('link')) {
        $myPath     = session('link');
        $loginPath  = url('/login');
        $previous   = url()->previous();

        if ($previous = $loginPath) {
            session(['link' => $myPath]);
        }else{
            session(['link' => $previous]);
        }
    }
    else{
        session(['link' => url()->previous()]);
    }
    return view('auth.login');
}

protected function authenticated(Request $request, $user)
{
    return redirect(session('link'));      
}

如果您有任何帮助，我们将不胜感激。

好的，您可以用与登录控制器类似的方式进行操作

public function showLoginForm()
{
    if (session('link')) {
        $myPath     = session('link');
        $loginPath  = url('/login');
        $previous   = url()->previous();

        if ($previous = $loginPath) {
            session(['link' => $myPath]);
        }else{
            session(['link' => $previous]);
        }
    }
    else{
        session(['link' => url()->previous()]);
    }
    return view('auth.login');
}

protected function authenticated(Request $request, $user)
{
    return redirect(session('link'));      
}

您首先需要在Register Controller中创建以下函数，以覆盖默认值并将URL保存到会话中

/**
* Show the application registration form.
*
* @return \Illuminate\Http\Response
*/
public function showRegistrationForm()
{
    if (session('link')) {
        $myPath     = session('link');
        $registerPath  = url('/register');
        $previous   = url()->previous();

        if ($previous = $registerPath) {
            session(['link' => $myPath]);
        }else{
            session(['link' => $previous]);
        }
    } else{
        session(['link' => url()->previous()]);
    }
    return view('auth.register');
}

然后再次在注册控制器中创建以下函数

protected function redirectTo()
{
    return redirect(session('link'))->with('success', 'Thank you for your previous transaction! Go to your Profile to review your transaction history.');
}

您可能还希望在其中设置默认路由，以防他们直接访问注册表表单。所以

protected function redirectTo()
{
    if(session('link')){
        return redirect(session('link'))->with('success', 'Thank you for your previous transaction! Go to your Profile to review your transaction history.');
    }
    return redirect('/home')->with('success', 'Thank you for your previous transaction! Go to your Profile to review your transaction history.');
}

你说的链接是重复的，这是我用来让登录正确重定向回上一页的链接。我想问的是，注册后我如何为用户做同样的事情。页面X只是一个视图吗？您是否向其传递了任何数据？因此，根据您所说的，用户位于/page1，然后转到/register并填写注册并提交。如果注册成功，您希望他们返回到/page1？@ColinMD是的，这是正确的。无论用户从哪个页面访问注册页面，都是我希望他们返回的页面。@UkraineInTheMembrane是的，第X页只是一个视图。关于我们的示例视图/页面。我正在通过数据库和foreach循环将数据传递到我的大多数页面。没问题，很高兴我能帮助hi ColinMd，我使用的代码完全相同，在提交注册表时出现了这个错误。ErrorException标头不能包含多个标头，新行检测到，知道原因吗？感谢您发现，您不能在函数redirectTo（）中使用redirect，您可以返回'home'；
