将产品设置为 laravel 中的特色

Question

我对如何同时仅将一种产品标记为特色产品有些困惑。我在我的产品 table featured 中添加了列，它接受 0 用于普通产品，1 用于特色产品。

只能有一种产品具有 1

的特色

所以我在 blade 下面的下拉列表中显示了所有产品

{{ 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>

像这样，我在下拉列表中显示了所有产品，管理员可以从中 select 另一个产品并将其标记为精选产品。已在下拉列表中销售当前产品。

这是我放入控制器的内容

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');
}

和路线

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

我如何才能在控制器中创建逻辑，以便将我在下拉列表中 select 的产品更新为 1 并在数据库中更新为 0？

目前错误是

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

Answer 1

您的表单应打开为：

{{ 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']);

你可以这样写你的逻辑：

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');
}

Answer 2

您需要设置表单动作

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

但我觉得这里少了点什么

将产品设置为 laravel 中的特色

Set product as featured in laravel

php

laravel
