Laravel: How to redirect after controller method execution

问题

web.php:

Route::post('caption/{id}/delete', 'DetailController@deleteCaption');

DetailController.php:

public function deleteCaption(Request $request, $id) {
    $caption = Caption::findOrFail($id);
    $caption->delete(); //doesn't delete permanently

    return response(204);
}

admin.blade.php:

<p value='{{$caption->id}}'>{{$caption->content}}</p>
<form action="caption/{{$caption->id}}/delete" method="post">
<button type="submit">Delete caption</button>
</form> 
<form action="caption/{{$caption->id}}/approve" method="post">
<button type="submit">Accept caption</button>
</form>

I want to make it so that after I delete an image, the user is redirected back to the admin page, located at localhost:8000/admin.

How can I do this? Documentation isn't understandable to me.

回答1:

You can redirect like

public function deleteCaption(Request $request, $id) {
    $caption = Caption::findOrFail($id);
    $caption->delete(); //doesn't delete permanently

    return redirect()->to('link/to/anywhere');
}

OR
You can redirect like this

return redirect()->back();

to your last state.

return route('yourRouteName');
//if there's parameters
return route('yourRouteName', ['id' => 1]);

回答2:

You can simply redirect to your defined route in your web.php:

public function deleteCaption(Request $request, $id) {
    $caption = Caption::findOrFail($id);
    $caption->delete(); //doesn't delete permanently

    return redirect('admin');
}

Checking out the routing and blade docs may assist as well.

回答3:

Since you want to return back to the same page. You can use Laravel's back function.

 return back();

To redirect user back to the page it came from.

回答4:

To redirect back use

return redirect()->back();

To redirect to specific route use

return return redirect()->route('route-name');
