Question

我想在按下编辑按钮时获取该ID的数据。我的所有字段都为空。我在同一页面上创建和编辑。

更新功能

price

编辑按钮

 public function update(Request $request)
{

    $user = User::findOrFail($request->user_id);

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

    return back();
}

admin.form

 <div class="modal fade" id="edit" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title" id="myModalLabel">Edit user</h4>
            </div>
            <form action="{{route('user.update','test')}}" method="post">
                {{method_field('patch')}}
                {{csrf_field()}}
                <div class="modal-body">
                    <input type="hidden" name="user_id" id="cat_id" value="">
                    @include('admin.form')
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                    <button type="submit" class="btn btn-primary">Save Changes</button>
                </div>
            </form>
        </div>
    </div>
</div>

我在其他一些表上使用了相同的函数技术，有些工作正常，有些却没有。谁能告诉我我在哪里做错了。

Answer 1

您应该传递变量 $ user

返回您的视图，以便您可以再次传播它，例如：

<input type="text" class="form-control" name="name" id="name" value={{$user->name}}>

所以你应该做这样的事情

public function update(Request $request){
    $user = User::findOrFail($request->user_id);
    $user->update($request->all());
    return back();
}

到 return view ('admin.form, compact('user'));

或者您也可以使用会话，以便检索数据，然后将其显示在想要显示的刀片上
