我想制作更新功能，但该功能不起作用，请帮我解决这个问题，这是我的代码：

这是路线

Route::resource('ItemName', 'ItemNameController');

这是控制器

public function update(Request $request, ItemName $itemName)
{
    request()->validate([
        'inc'            => 'required',
        'item_name'      => 'required',
        'short_name'     => 'required',
        'definition_eng' => 'max:1000', 
        'definition_ind' => 'max:1000',
    ]);

    $itemName->update($request->all());

    return redirect('ItemName')->with('success', 'Item Name Updated Successfully');
}

这是视图

<form action="{{ action('ItemNameController@update', $ItemName->id) }}" method="post">
    @csrf
    @method('PUT')
    <input class="form-control col-4" type="text" name="inc" placeholder="INC" value="{{$ItemName->inc}}">
    <input class="form-control mt-2" type="text" name="item_name" placeholder="Item Name" value="{{$ItemName->item_name}}">
    <input class="form-control mt-2" type="text" name="short_name" placeholder="Short Name" value="{{$ItemName->short_name}}">
    <input class="form-control mt-2" type="text" name="definition_eng" placeholder="English Definition" value="{{$ItemName->definition_eng}}">
    <input class="form-control mt-2" …

这是我的代码：

路线

Route::resource('ItemName', 'ItemNameController');

控制器

public function destroy(ItemName $itemName)
{
    $itemName->delete();
    return redirect('ItemName')->with('success', 'Item Has Been Delete');
}

看法

<form action="{{ route('ItemName', $ItemName->id) }}" method="post">
    @csrf
    @method("DELETE")
    <input type="submit" class="btn btn-danger btn-sm" href="{{ $ItemName- 
    >id }}" value="Delete" onclick="return confirm('Are You Sure To Delete 
    This Item? #{{ $ItemName->inc }} ')">
</form>

问题是代码无法删除表中的项目，有什么帮助吗？谢谢

FROM chatting, users
WHERE
CASE 
WHEN user_one = 36 
THEN user_two = 55
WHEN user_two = 55 
THEN user_one = 36 
END

but i get this error after "THEN user_two = 55" The error is "Incorrect syntax near '='."
