CRUD Laravel 5 how to link to destroy of Resource Controller?

Question

I have a link

Answer 1

If you really want to visit the destroy action on delete route by HTML, then there is an approach to use HTTP Method Spoofing which means that you could visit a delete HTTP method by adding a hidden input named _method with the value of `"DELETE". Same way can be used for "PUT" and "PATCH" HTTP method.

Below is a sample for DELETE method.

<form action="/tasks/5" method="POST">
<input type="hidden" name="_method" value="DELETE">
</form>

will get the route

DELETE  /tasks/{id}  destroy     tasks.destroy

if you use laravel collective, you can write this way in your views.

{!! Form::open(['url' => '/tasks/'.$cat->id, 'method' => 'delete']) !!}
{!! Form::submit('Delete', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}

You need to send a DELETE request instead of a GET request. You can't do that with a link, so you have to use an AJAX request or a form.

Here is the generic form method:

<form action="{{ URL::route('user.destroy', $members['id'][$i]) }}" method="POST">
    <input type="hidden" name="_method" value="DELETE">
    <input type="hidden" name="_token" value="{{ csrf_token() }}">
    <button>Delete User</button>
</form>

If you're using Laravel 5.1 or later then you can use Laravel's built-in helpers to shorten your code:

<form action="{{ route('user.destroy', $members['id'][$i]) }}" method="POST">
    {{ method_field('DELETE') }}
    {{ csrf_field() }}
    <button>Delete User</button>
</form>

If you're using Laravel 5.6 or later then you can use the new Blade directives to shorten your code even further:

<form action="{{ route('user.destroy', $members['id'][$i]) }}" method="POST">
    @method('DELETE')
    @csrf
    <button>Delete User</button>
</form>

My, non-ajax version. I use it in dropdowns (bootstrap) in resource list (datatables as well). Very short and universal.

Global jQuery method:

$('.submit-previous-form').click(function (e) {
    e.preventDefault();
    $($(this)).prev('form').submit();
});

And then we can use everywhere something like this:

{{ Form::open(['route' => ['user.destroy', $user], 'method' => 'delete']) }} {{ Form::close() }}
<a href="#" class="dropdown-item submit-previous-form" title="Delete user"><i class="icon-trash"></i> Delete him</a>

Recommend: It's easy to integrate with confirms scripts for example swal.

Answer 4

If you're looking to do this via a regular link instead of through AJAX or another type of form request you can set up a special route that will respond to a normal GET request:

In your routes, define this in addition to the resource:

Route::get('user/{site}/delete', ['as' => 'user.delete', 'uses' => 'UserController@destroy']);

In your view:

<a href="{{ route('user.delete', $user->id) }}">Delete this user</a>

In your controller:

public function destroy(User $user)
{
  $user->delete();
  return redirect()->route('users.index');
}

If you want to use a link, you can use a library I have created that lets people make links that behave like POST, DELETE... calls.

If we need to use an anchor to trigger the destroy route, and we don't want to use ajax, we can put a form inside our link, and submit the form using the onclick attribute:

<a href="javascript:void(0);" onclick="$(this).find('form').submit();" >
    <form action="{{ url('/resource/to/delete') }}" method="post">
        <input type="hidden" name="_method" value="DELETE">
    </form>
</a>
