Question

我有点不知道如何在当时只标记一种产品。我在我的产品表featured中添加了列，该列接受正常商品0和特色商品1。

只能展示一种产品

所以我在下拉列表中放入了显示所有产品的刀片

{{ Form::open() }}
<div class="form-group">
    <label for="title" class="control-block">Assign Product as Featured:</label>
        <select class="form-control" name="featured">       
            @foreach($products as $featured)                
                <option value="{{ $featured->product_id }}" {{ $featured->featured == 1 ? "selected" : ""}}>{{ $featured->title }}</option>
            @endforeach
        </select>
</div>   
<button type="submit" class="btn btn-primary">Make Product Featured</button>        
{{ Form::close() }}

<p>Current Featured Product: <strong>@if($featured->featured == 1){{ $featured->title }}@endif</strong></p>

因此，我在下拉列表中显示所有产品，管理员可以从中选择另一个产品并标记为精选。已经有市场当前的产品下降。

这就是我在控制器中的内容

public function products() {
    $products = Product::all();
    return View::make('site.admin.products', [
        'products' => $products
    ]);
}

public function featuredProduct($productId) {

    $product = Product::where('product_id', $productId)->first();
    if (!$product) {
        App::abort(404);
    }

    $product_featured = Input::get('featured', $product->featured);
    $product->featured = $product_featured;
    $product->save();
    return Redirect::to('/admin/products');
}

路线

Route::get ('/admin/products', ['uses' => 'AdminController@products', 'before' => 'admin']);
Route::post ('/admin/products/{productId}', ['uses' => 'AdminController@featuredProduct', 'before' => 'admin']);

我如何在控制器中创建逻辑，以便将我在下拉列表中选择的产品更新为1，将当前更新为0数据库？

目前错误是

production.ERROR：Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException

Answer 1

您的表单应按以下方式打开：

{{ Form::open(['url' => '/admin/products/feature', 'method' => 'post']) }}

你的路线应该是：

Route::post('/admin/products/feature', ['uses' => 'AdminController@featuredProduct', 'before' => 'admin']);

你可以把你的逻辑写成：

public function featuredProduct() {
    $product_featured_id = Input::get('featured');

    $product = Product::where('product_id', $product_featured_id)->firstOrFail();

    Product::where('featured', 1)->update(['featured' => 0]); // this will make all product of featured 0

    $product->featured = 1;
    $product->save();
    return Redirect::to('/admin/products');
}

您需要设置表单操作

{{ Form::open(array('url' => '/admin/products/' . $product_id)) }}

但我觉得这里缺少了一些东西

将产品设置为laravel中的特色
