適應(yīng)于： 已使用layui的頁面 && 想用后端生成頁碼 && 又使用了 webman的 這種illuminate數(shù)據(jù)庫 的情況

我的使用的部分示例：

function index(Request $request){
    $limit=$request->get('limit',8);
    $model = new XXXModel();
    // 
    $min_price = $request->get("min_price", '');
    if (is_numeric($min_price)) {
        $model = $model->where("price", '>=', $min_price);
    }
    // 
    $category = $request->get("category", '');
    if ($category) {
        $model = $model->where("category", '=', $category);
    }
    //省略  ...

    $paginate = $model->paginate($limit); 

    return $this->layout('', [
        'items' => $paginate->items(),
        'pager'=>\app\services\LayuiPaginate::make($paginate),//這里這里這里
        "category" => $category,
        "keyword" => $keyword,
        'min_price' => $min_price,
        //...
    ]);
}

html部分：

    <div>
        <?=var_dump($items)?>   
    </div>
    <div class="layui-row">
        <div class="layui-col-md12" style="text-align: center; margin-top: 30px;">
            <?=$pager?><!--這里這里這里-->
        </div>
    </div>

get參數(shù)有很多：
