laravel- 404 未找到但路线存在

Question

我正在尝试提交一个表单来更新我在数据库中的表并测试控制器是否正常工作，我做了一些测试。我正在学习如何使用 POST 方法传递数据。这是我的代码。

路线：

Route::prefix('dashboard')->group(function () {
    // Route for panel.
    Route::prefix('panel')->group(function () {
        // Return index home page for panel.
        Route::get('/', 'Panel\DashboardController@index');
        // Update order information (delivery date and order status)
        Route::put('/update-order-information', 'Order\OrderController@update');
    });
}

panel.blade.php（视图）：

<table class="table table-light ">
    <thead class="thead-dark">
    <tr>
        <th scope="col">Order ID</th>
        <th scope="col">Delivery Date</th>
        <th scope="col">Order Info</th>
        <th scope="col">Order Status</th>
        <th scope="col">Purchase Order</th>
    </tr>
    </thead>
    <tbody>
    @foreach ($customerOrders as $customerOrder)
    <tr>
        <form action="/dashboard/panel/update-order-information/{{$customerOrder->order_id}}" method="POST">
            <input type="hidden" name="_method" value="PUT">
            <input type="hidden" name="_token" value="{{ csrf_token() }}">
            <td>{{$customerOrder->order_id}}</td>
            <td>
                <input name='delivery_date' class="date form-control" type="text" placeholder="Select delivery date"
                       autocomplete="off">
            </td>
            <td>{{$customerOrder->product_name}}</td>
            <td>
                <select id="status" name="status">
                    <option value="inProgress">In Progress</option>
                    <option value="shipped">Order Shipped</option>
                    <option value="cancelled">Cancelled</option>
                </select>
            </td>
            <td>{{$customerOrder->purchase_order}}
                <input type="submit" value="Submit">
            </td>
        </form>
    </tr>
    @endforeach
    </tbody>
</table>

OrderController.php：

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function update(Request $request, $id)
{
    $order = new Order();
    findOrFail($id);
    $order->order_id = $request->input('delivery_date');
    $order->order_status = $request->input('status');
    $order->save();
}

当我点击提交按钮时，它给了我一个 404 页面。谁能指出我的错误？

Answer 1

尝试在表单操作中使用 URL。

<form action="{{ url('dashboard/panel/update-order-information') }}" method="POST" > 
   <input type="hidden" name="_method" value="PUT">
   <input type="hidden" name="_token" value="{{ csrf_token() }}">
</form>

或者你可以定义route name如下。

Route::put('/update-order-information', 'Order\OrderController@update')->name('update.order');

<form action="{{ route('update.order') }}" method="POST" > 
   <input type="hidden" name="_method" value="PUT">
   <input type="hidden" name="_token" value="{{ csrf_token() }}">
</form>

编辑：-

在您的控制器方法中，您期望 $id 但在 URL 中您没有传递订单 ID。

<form action="{{ route('update.order',['id'=>$customerOrder->order_id]) }}" method="POST" > 
   <input type="hidden" name="_method" value="PUT">
   <input type="hidden" name="_token" value="{{ csrf_token() }}">
</form>

Route.php

Route::put('/update-order-information/{id}', 'Order\OrderController@update')->name('update.order');

控制器。

public function update(Request $request, $id)
{
    dd("hello");
    // $panel = new Order();
    // $panel->order_id = $request->input('delivery_date');
}

Answer 2

像这样在你的网址前添加/

<form action="/dashboard/panel/update-order-information/{{$customerOrder->id}}" method="POST" > 

编辑：

 /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        $panel = Order::findOrFail($id)
        $panel->column_in_your_database = $request->input('delivery_date');
        $panel->save();
    }
