Laravel刪除按鈕拋出錯誤「頁面無法找到

Question

這是我的代碼

視圖

<form action="/categories/ {{ $category->id }}" method="POST"> 
    {{ csrf_field() }} 
    {{ method_field('DELETE') }} 

    <button>Delete Task</button> 
</form> 

控制器方法

public function destroyCategory($id) 
{ 

    Categories::findOrFail($id)->delete(); 

    return redirect('/categories'); 
} 

路線

Route::post('categories','FilesController@destroyCategory'); 

表在局部看來，可以問題

Answer 1

您發送您的形式DELETE方法，但你抓住它作爲post而不是delete您route文件&裏面還有你在自己route文件分配URL參數。

<form action="/categories/{{ $category->id }}" method="POST"> 
    {{ csrf_field() }} 
    {{ method_field('DELETE') }} 

    <button type="submit">Delete Task</button> 
</form> 

route.php

Route::delete('categories/{id}','FilesController@destroyCategory'); 

Answer 2

您/categories後有空間，你不用提交按鈕：

<form action="/categories/{{ $category->id }}" method="POST"> 
    {{ csrf_field() }} 
    <input name="_method" type="hidden" value="DELETE"> 
    <input class="btn btn-danger" type="submit" value="Delete Task"> 
</form> 

或用Laravel集體形式：

{!! Form::open(['method' => 'Delete', 'route' => ['task.delete', $category->id]) !!} 
{!! Form::submit('Delete Task') !!} 
{!! Form::close() !!} 

此外，您正在使用post路線而不是delete。而且，正如@Rimon汗說，你不抓一個類別的ID：

Route::delete('categories/{id}', ['as' => 'task.delete', 'uses' => 'FilesController@destroyCategory']); 

Answer 3

你可以這樣說：

你的路線應該是這樣的：

Route::post('categories/{id}','FilesController@destroyCategory')->name('delete_categories'); 

控制器應該是這樣的：

public function destroyCategory($id) 
{ 
    Categories::findOrFail($id)->delete(); 
    return redirect()->to('/'); 
} 

和HTML會是這樣的：

<form action="{{ route('delete_categories', ['id' => $category->id]) }}" method="POST"> 
    {{ csrf_field() }} 
    {{ method_field('DELETE') }} 

    <button type="submit">Delete Task</button> 
</form> 

希望這有助於
