Laravel路由傳遞變量到控制器不一樣

Question

我發現了另一個錯誤。 我試圖按ID刪除圖書。 我有數據

--------------
| id |  name |
--------------
| 1  | book1 |
| 2  | book2 |
| 3  | book3 |

因此，當我刪除I​​D為2的書時，控制器始終會收到ID3。當我嘗試刪除ID為1時，情況仍然如此，控制器會獲得ID 3（總是最后一條記錄）

此視圖刀片

@foreach($datas as $data)
<a href="# {{ $data->id }}"
   onclick="event.preventDefault();
   document.getElementById('remove-form').submit();"
  rel="tooltip" title="Hapus" class="btn btn-danger">
</a>

<form id="remove-form" action="{{ url('/dashboard/book/delete/'. $data->id) }}" method="post">
    {{ csrf_field() }}
    {{ method_field('DELETE') }}
</form>
@endforeach

這條路線

Route::group(['namespace' => 'Backend'], function ()
{
   Route::resource('/dashboard/book', 'BookController'); //
   Route::delete('/dashboard/book/delete/{id}', 'BookController@destroy');
}

這個控制器

public function index()
    {
        $datas = Book::all();
        return view('backend.bookview', compact('datas'));
    }
public function destroy($id)
{
    Book::where('id', $id)->delete();
    return redirect('/dashboard/book')->with('ok', translate('back/book.destroyed'));
}

UPDATE

單個html頁面上不能有多個id remove-form 。 而是使用這樣的類：

@foreach($datas as $data)
    <div class="delete-block">
        <a href="# {{ $data->id }}"
          rel="tooltip" title="Hapus" class="btn btn-danger delete-btn">
        </a>

        <form class="remove-form" action="{{ url('/dashboard/book/delete/'. $data->id) }}" method="post">
            {{ csrf_field() }}
            {{ method_field('DELETE') }}
        </form>
    </div>
@endforeach

並且您的腳本應為：

$(function() {

    $('.delete-btn').on('click', function(e) {
        $(this).closest('.delete-block').find('form').submit();
    });

});

 $(function() { $('.delete-btn').on('click', function(e) { e.preventDefault(); console.log($(this).closest('.delete-block').find('form').attr('action')); // $(this).closest('.delete-block').find('form').submit(); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="delete-block"> <a href="#1" rel="tooltip" title="Hapus" class="btn btn-danger delete-btn"> Delete 1 </a> <form id="remove-form" action="/dashboard/book/delete/1" method="post"> <input type="hidden"> </form> </div> <div class="delete-block"> <a href="#2" rel="tooltip" title="Hapus" class="btn btn-danger delete-btn"> Delete 2 </a> <form id="remove-form" action="/dashboard/book/delete/2" method="post"> <input type="hidden"> </form> </div> <div class="delete-block"> <a href="#3" rel="tooltip" title="Hapus" class="btn btn-danger delete-btn"> Delete 3 </a> <form id="remove-form" action="/dashboard/book/delete/3" method="post"> <input type="hidden"> </form> </div> 

內部控制器

您應該通過從數據庫中按ID提取單個記錄來刪除圖書，如下所示：

public function destroy($id)
{
  $book = Book::find($id);
  if($book) {
    $book->delete();
    return redirect('/dashboard/book')->with('ok', translate('back/book.destroyed'));
  }
  // return error response - book deletion failed!
  return redirect('/dashboard/book')->with('Error', translate('back/book.destroyed.error'));
}

使用find()通過primary key從數據庫中獲取單個記錄。

但是，如果您知道模型的主鍵，則可以刪除模型而不檢索它。 為此，請調用destroy方法：

Book::destroy(1); // Can pass single primary key
Book::destroy([1, 2, 3]); // Can pass an array of primary keys
Book::destroy(1, 2, 3); // Can pass multiple primary keys via arguments

希望這可以幫助！

Answer 2

發生這種情況是因為document.getElementById('remove-form').submit()總是選擇id => 3的最后一個表單。

因此，將其更改為以下代碼即可使用：

@foreach($datas as $data)
    <form method="POST" action="{{ url('/dashboard/book/delete/'. $data->id) }}"  style="display: inline-block;">
        {{ csrf_field() }}
        {{ method_field('DELETE') }}
        <button onclick="return confirm('Do you really want to delete this item?');" type="submit" class="btn btn-danger" data-original-title="Delete Item" data-toggle="tooltip" data-placement="top" title="">
            Delete
        </button>
    </form>
@endforeach
