Question

我使用文本框和下拉菜单创建了一些搜索过滤器，所以当我点击搜索按钮时，我想使用这些过滤器来查询雄辩的关系。

搜索工作正常，我得到了正确的结果，但问题在于分页。当我点击下一页按钮（或任何其他页面）时，结果是结果，我再次获得所有内容。

我知道这是因为我在点击分页时没有做请求所以我的问题是我如何执行相同的查询但使用分页？

这是我的控制器功能

public function index(Request $request)
{
    if(!empty($request)) {

        $products = Product::with(['supplier', 'carrier', 'name']);

        if($request->name) {
            $products = $products->whereHas('Name', function ($query) use ($request) {
                $products = $query->where('Name', $request->name);
            });
        }
        if($request->subtype) {
            $products = $products->whereHas('SubType', function ($query) use ($request) {
                $products = $query->where('SubTypeId', $request->subtype);
            });
        }
        if($request->supplier) {
            $products = $products->whereHas('Supplier', function ($query) use ($request) {
                $products = $query->where('SupplierId', $request->supplier);
            });
        }
        if($request->carrier) {
            $products = $products->whereHas('Carrier', function ($query) use ($request) {
                $products = $query->where('CarrierId', $request->carrier);
            });
        }

        $products = $products->paginate(8);
    }
    else {
        $products = Product::with(['supplier', 'carrier', 'name'])->paginate(8);
    }

    $suppliers = Supplier::all();
    $carriers = Carrier::all();
    $subtypes = SubType::all();

    $options = array(
        'products' => $products,
        'suppliers' => $suppliers,
        'subtypes' => $subtypes,
        'carriers' => $carriers
    );

    return view('products.index')->with($options);
}

我可以通过更改控制器功能来修复它。我没有IF声明

$products = Product::with(['supplier', 'carrier', 'name']);

if($request->name) {
    $products = $products->whereHas('Name', function ($query) use ($request) {
        $query->where('Name', $request->name);
    });
}
if($request->subtype) {
    $products = $products->whereHas('SubType', function ($query) use ($request) {
        $query->where('SubTypeId', $request->subtype);
    });
}
if($request->supplier) {
    $products = $products->whereHas('Supplier', function ($query) use ($request) {
        $query->where('SupplierId', $request->supplier);
    });
}
if($request->carrier) {
    $products = $products->whereHas('Carrier', function ($query) use ($request) {
        $query->where('CarrierId', $request->carrier);
    });
}

$products = $products->paginate(8);

$suppliers = Supplier::all();
$carriers = Carrier::all();
$subtypes = SubType::all();

$options = array(
    'products' => $products,
    'suppliers' => $suppliers,
    'subtypes' => $subtypes,
    'carriers' => $carriers
);

return view('products.index')->with($options);

在我看来，我放置了分页链接，我替换了

{{ $products->links() }}

与

{{ $products->appends(\Request::except('_token'))->render() }}

Laravel 5搜索结果分页
