Question

我发现了一个不同的错误。我试图通过id删除书籍。我有数据，例如

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

所以，当我删除id为2的书籍时，控制器总是会收到id 3。当我试图删除id 1时，情况仍然如此，控制器获得id 3（总是最后一条记录）

此视图刀片

@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

这条路线

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

这个控制器

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'));
}

您无法在单个html页面上拥有多个ID remove-form。而是使用这样的类：

@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

你的脚本应该是：

$(function() {

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

});

＆＃13;

$(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();
  });

});

＆＃13;

<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>

内部控制器

您应该通过从数据库中获取id的单个记录来删除该书，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()从数据库中通过primary key获取单个记录。

但是，如果您知道模型的主键，则可以删除模型而不检索它。为此，请调用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

Answer 2

这种情况正在发生，因为document.getElementById('remove-form').submit()始终选择具有id =＆gt;的最后一个表单3。

因此，将其更改为以下代码，它将起作用：

@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

Laravel路由传递变量到控制器不一样
