使用自定义刷新的会话数据注册后的Laravel自定义重定向

Question

I am building an app with Laravel 5.8 where, after registration or login, the user is redirected to a custom page along with a flashed session data, displayed on the page, that says "Welcome!".

I noticed that default redirect behavior in the RegisterController is a simple string, that does not allow me to add my custom redirect.

  * Where to redirect users after registration.
     *
     * @var string
     *
      protected $redirectTo = '/custompage';

I tried modifying this default behavior replacing the string with a function:

protected function redirectTo()
{
    /* generate URL dynamically */
     return redirect('/custompage')->with('status', 'Welcome!');
}

But I get the Warning

ErrorException (E_WARNING) Header may not contain more than a single header, new line detected

So, how to redirect to the custom page AND add my custom flashed data? Of course without modifying any vendor code.

Thanks in advance

Answer 1

change this to

protected function redirectTo()
{
    /* generate URL dynamicaly */
     return '/custompage';
}

It only returns path not the and you do not need redirect() here.

and added session data using Session::flash() or Session::put() depending on your requirement.

You can achieve what you described in different ways. A simple way will be to use the url of your custom route in the RegisterController, then add that route to your route and define a controller function accordingly.

You will keep your RegisterController like this:

* Where to redirect users after registration.
     *
     * @var string
     *
      protected $redirectTo = '/custompage';

Then add a route for it:

Route::any('custompage', array('as' => 'custompage', 'uses' => 'HomeController@custompage'));

And Define a controller function as you desire.

You can do that in the redirectTo method. This method should return a string not a response object. So it should be like this

protected function redirectTo()
{
    /* flash data to the session here */
    session(['status', 'Welcome']);
     return '/custompage';
 }
