在 Laravel 中附加带有搜索结果的排序路线

Question

我想将我的搜索结果 /search?allsearch= 和 url /search?sort= 排序在一起，但我还找不到解决方案。这是我的代码：

<form class="form-inline my-2 my-lg-0 rounded left-addon-search inner-addon" action="/search" method="GET">
    <i class="fas fa-search"></i>
    <input type="text" name="allsearch" class="search-field rounded" placeholder="Search" aria-label="Search" aria-describedby="search-addon" />
</form>

<select id="sort" name="sort">
    <option value="">Relevance</option>
    <option value="product_price_low_high" @if(isset($_GET['sort']) && $_GET['sort']=="product_price_low_high") selected="" @endif>Price: Low to High</option>
    <option value="product_price_high_low" @if(isset($_GET['sort']) && $_GET['sort']=="product_price_high_low") selected="" @endif>Price: High to Low</option>
    <option value="product_latest" @if(isset($_GET['sort']) && $_GET['sort']=="product_latest") selected="" @endif>Latest Arrivals</option>
</select>

我的控制器：

$search = $request->allsearch;

$product = DB::table('brands')
    ->join('products', 'brands.id', '=', 'products.brandid')
    ->where('productname','like','%'.$search.'%')
    ->OrWhere('name','like','%'.$search.'%');

// sorting product
if (isset($_GET['sort']) && !empty($_GET['sort'])) {
    if ($_GET['sort'] == "product_price_low_high") {
        $product->orderBy('productprice', 'asc');
    } elseif ($_GET['sort'] == "product_price_high_low") {
        $product->orderBy('productprice', 'desc');
    } elseif($_GET['sort'] == "product_latest") {
        $product->orderBy('id', 'desc');
    }
}

$product = $product->get();

我的路线：

Route::get('/search','ProductController@search')->name('allsearch', 'sort');

独立地，/search?allsearch= 和 /search?sort= 将起作用。但是如果我尝试搜索某些东西，然后对结果进行排序，它会清除搜索请求。知道如何让它工作吗？

您必须将请求值设置为表单，以便您可以同时使用它们。您可以对每种形式的缺失值使用隐藏输入搜索表单

<form class="form-inline my-2 my-lg-0 rounded left-addon-search inner-addon" action="{{ route('search') }}" method="GET">
    <i class="fas fa-search"></i>
    <input type="text" name="allsearch" value="{{ request()->allsearch }}" class="search-field rounded" placeholder="Search" aria-label="Search" aria-describedby="search-addon" />
    <input type="hidden" name="sort" value="{{ request()->sort }}" />
</form>

排序形式

<form class="form-inline my-2 my-lg-0 rounded left-addon-search inner-addon" action="{{ route('search') }}" method="GET">
    <select id="sort" name="sort">
        <option value="">Relevance</option>
        <option value="product_price_low_high" @if (request()->sort == "product_price_low_high") selected @endif>Price: Low to High</option>
        <option value="product_price_high_low" @if (request()->sort == "product_price_high_low") selected @endif>Price: High to Low</option>
        <option value="product_latest" @if (request()->sort == "product_latest") selected @endif>Latest Arrivals</option>
    </select>
    <input type="hidden" name="allsearch" value="{{ request()->allsearch }}" />
</form>

为什么你的路线有两个名字？？路线应该有一个唯一的名字

Route::get('search', 'ProductController@search')->name('search');

并在控制器中

use Illuminate\Http\Request;
public function search(Request $request)
{
    $search = $request->allsearch;

    $product = DB::table('brands')
        ->join('products', 'brands.id', '=', 'products.brandid')
        ->where('productname', 'like', '%'.$search.'%')
        ->orWhere('name', 'like', '%'.$search.'%');

    if ($request->sort == "product_price_low_high") {
        $product->orderBy('productprice', 'asc');
    } elseif ($request->sort == "product_price_high_low") {
        $product->orderBy('productprice', 'desc');
    } elseif ($request->sort == "product_latest") {
        $product->orderBy('id', 'desc');
    }

    $product = $product->get();
    return response/view
}

you are using laravel, so try to code as the laravel way
