Laravel从表列表/ db中删除项目

Question

I am trying to delete item from a generated table of items which are from a database table.

My Route:

Route::delete('destroy/{deviceID}', ['as' => 'destroyDevice', 'uses' => 'DeviceController@destroyDevice']);

My Controller method to delete an item:

public function destroyDevice(Request $request, $deviceId = 0)
{
    $device = Device::find($deviceId);

    if($device)
    {
        $device->delete();
        return redirect()->route('index')->with('success', 'Erfolgreich gelöscht');
    }
    else
    {
        return redirect()->route('index')->with('error', 'Fehler');
    }
}

And my blade template:

                <form action="{{ route('destroyDevice', $deviceValue->id) }}" method="post" name="delete_device">
                    <input type="hidden" name="_method" value="delete">
                    <input type="hidden" name="_token" value="{{ csrf_token() }}">
                    <input type="hidden" name="id" value="{{ $deviceValue->id }}">
                    <td>
                        <button type="submit" class="btn btn-danger" name="destroy_device">
                            <span class="glyphicon glyphicon-trash"></span>
                        </button>
                    </td>
                </form>

If I click on the button nothing happens no error no Response, what am I doing wrong.

If I click on the third delete button the form holds this:

<form action="http://localhost/app/public/device/destroy/3" method="post" name="delete_device"></form>

You can solve this by putting the form inside a td tag in that table.

Like this:

  <td> <!--  <--- put these -->
      <form action="{{ route('destroyDevice', $deviceValue->id) }}" method="post" name="delete_device">
          <input type="hidden" name="_method" value="delete">
          <input type="hidden" name="_token" value="{{ csrf_token() }}">
          <input type="hidden" name="id" value="{{ $deviceValue->id }}">

              <button type="submit" class="btn btn-danger" name="destroy_device">
                  <span class="glyphicon glyphicon-trash"></span>
              </button>

      </form>
  </td> <!--  <--- put these -->

I think the form gets ignored somehow due to not being valid, but I am not 100% sure. May people edit this answer ;)

Answer 2

该参数区分大小写，因此它应该是deviceID而不是deviceId

public function destroyDevice(Request $request, $deviceID = 0)

Answer 3

Maybe you have some script that prevents the form to submit, some prevent default maybe on button click or on form submit. Check that.
