Tp5的 多项搜索框（下拉框+输入框）

1.静态页面  注意静态的下拉框的name值跟显示的下拉框变量值 相同，不同于字段名，id可以为字段名

<span style="font-size: 16px;font-family: '微软雅黑';float: left;line-height: 34px;">分类</span>
<select name="result1" id="product_special_id" style=" 240px;height: 36px;float: left;margin-left: 10px;">
    <option value="0"></option>
    {php} for($i=0;$i<count($result1);$i++){ {/php}
    <option value="{$result1[$i]['id']}">{$result1[$i]['product_category_name']}</option>
    {php} } {/php}
</select>
<input style="160px;margin-left: 32px;" value="" name="product_name" id="product_name" type="text" class="form-control" placeholder="输入商品名称"/>
<span class="input-group-btn" style="margin-left: -10px !important;">
    <a href="javascript:void(0)" onclick="selectsome()" class="btn btn-primary"><i class="fa fa-search"></i> 搜索</a>
</span>
2.js里面

function selectsome() {
    var product_name = $('#product_name').val();
    var product_special_id = $('#product_special_id').val();
    // console.log(product_special_id);
    window.location.href = "__ROOT__/index.php/admin/Youpro/index/product_special_id/"+product_special_id+
        "/product_name/"+product_name;
}

3.控制器内

public function index(){
        $article = new YouproModel();
        //下拉框
        $result1 = $article->getProSelect();
        $this->assign('result1', $result1);
        $map = [];
        //拿到了title
        $title = input('product_name');
        //拉取下拉框值
        $ket_select = input('product_special_id');
        if($ket_select != 0){
            $map['product_special_id'] = ['=',$ket_select];
        }
        //        var_dump($title);
        if($title&&$title!=""){
            $map['product_name'] = ['like',"%" . $title . "%"];
            $count = Db::table('think_product')->where($map)->order('id asc')->count();
            $this->assign('count', $count);
        }
        $this->assign('title', $title);
        $count = $article->getProIndex($map);
        // 查询状态为1的用户数据 并且每页显示10条数据 总记录数为$count(总共有多少条数据)
        $product = $article->getProIndexState($map,$map);
        // 获取分页显示
        $page = $product->render();
        // 把分页数据赋值给模板变量list
        $this->assign('product', $product);
        // 模板变量赋值
        $this->assign('page', $page);
        $this->assign('count', $count);
//        echo Db::table('think_product')->getLastSql();
        return $this->fetch();
    }
