Question

我试图根据GET中的内容添加我的查询：

public function index($type_id) {
    $Product = new Product;
    $Product->where('type_id', $type_id);
    if(array_key_exists('ages', Input::get())) {
        $Product->where('age_id', $_GET['ages']);
    }
    $products = $Product->get();
    $productsPaginated = $Product->where('type_id', $type_id)->paginate(2);
    return View::make('products.products', array(
                'products' => $products,
                'productsList' => $productsPaginated
                    )
    );
}

但它所做的只是带回每一条记录。

我做错了什么？

这就是我渲染过滤器的方式：

    $brands = $prices = $ages = $brandsUsed = $agesUsed = array();
    $out = '';
    foreach ($productsList as $product) {
        $brands[$product->brands->id] = $product->brands->brand;
        $brandsUsed[] = $product->brands->id;
        $prices[] = $product->price;
        $ages[$product->ages->id] = $product->ages->age;
        $agesUsed[] = $product->ages->id;
    }

    $brandsUsed = array_count_values($brandsUsed);
    $brands = array_unique($brands);
    $params = Input::get();
    $lastParams = http_build_query($params);
    unset($params['brand']);
    $params = http_build_query($params);
    if (count($brands) > 0) {
        $out .= '<h5>Brands</h5>';
        foreach ($brands as $brandId => $brandName) {

            if (stristr($lastParams, '&brand=' . $brandId) || stristr($lastParams, 'brand=' . $brandId)) {
                $out .= '<a class="filter-link" href="' . Request::path() . '?' . $params . '">';
            } else {
                $out .= '<a class="filter-link" href="' . Request::path() . '?' . $params . '&brand=' . $brandId . '">';
            }
            $out .= '<span class="cbox">';

            if (stristr($lastParams, '&brand=' . $brandId) || stristr($lastParams, 'brand=' . $brandId)) {
                $out .= '<span class="cbox-checked"></span>';
            }

            $out .= '</span>';
            $out .= $brandName;
            $out .= ' (' . $brandsUsed[$brandId] . ')';
            $out .= '</a>';
        }
    }

你无法在对象上创建查询，你应该这样做：

public function index($type_id) {
    $product = Product::where('type_id', $type_id);
    if(array_key_exists('ages', Input::get())) {
        $product->where('age_id', $_GET['ages']);
    }
    $productsAll = $product->get();
    $productsPaginated = $product->where('type_id', $type_id)->paginate(2);
    return View::make('products.products', array(
                'products' => $productsAll,
                'productsList' => $productsPaginated
                    )
    );
}

您还应该考虑获取所有产品和分页产品是否有意义。如果您的数据库中有许多产品，则需要很长时间才能获得所有产品。

我也不确定你想要获得$productsPaginated的确切内容。我想你需要在这里建立新的查询：

$productsPaginated = Product::where('type_id', $type_id)->paginate(2);

编辑

如果您只想使用一个过滤器来计算产品数量，请在此处使用：

public function index($type_id) {
    $product = Product::where('type_id', $type_id);

    $productCount = $product->count();

    if(array_key_exists('ages', Input::get())) {
        $product->where('age_id', $_GET['ages']);
    }
    $productsPaginated = $product->paginate(2);

    return View::make('products.products', array(
                'productsCount' => $productCount,
                'productsList' => $productsPaginated
                    )
    );
}

Laravel查询不起作用
