Laravel传递数据到控制器 [英] Laravel Passing Data to Controller

问题描述

我刚开始学习laravel，想知道如何将与路由无关的数据传递给控制器​​。我想要完成的是创建一个能够嵌套项目的todo项目。

I just starting learning laravel and was wondering how to pass data unrelated to the route to a controller. What I'm trying to accomplish is create a todo item that is able to have nested items.

<a class="btn btn-success" href="{{route('lists.items.create',4)}}">Create New Item</a>

4只是一个硬编码的例子，看看它是否工作。

The 4 is just a hard-coded example to see if it was working.

public function create(TodoList $list, $item_id = null)
{
    dd($item_id);
    return view('items.create', compact('list'));
}

所以如果你创建一个项目， ，它将默认为 null ，否则设置它传递的任何内容。但我得到一个 NotFoundHttpException 。我将如何做到这一点。

So if your creating an item and don't pass in a parameter for id, it will default to null otherwise set it to whatever was passed in. However I'm getting a NotFoundHttpException. How would I be able to accomplish this.

任何帮助欢迎：）

推荐答案

路由，例如：

Route::get('create-item/{id}', [
    'as' => 'lists.items.create', 
    'uses' => 'MyController@create'
])

现在，像下面这样调用路由：

Now, call the route like:

<a class="btn btn-success" href="{{route('lists.items.create', ['id' => 4])}}">Create New Item</a>
