Question

您好我已经在这方面工作了近2个小时了。我似乎无法找到关于jqGrid上没有显示结果的错误。我试着回应json_encode并显示出来。我的jqGrid正在我的本地网站上工作但不在现场工作。我传递一个参数，以便它不会显示其他未包含的项目。

这是我得到的：

//控制器

function all ($eid)
    {
        $page = isset($_POST['page'])?$_POST['page']:1; 
        $limit = isset($_POST['rows'])?$_POST['rows']:10; 
        $sidx = isset($_POST['sidx'])?$_POST['sidx']:'rank'; 
        $sord = isset($_POST['sord'])?$_POST['sord']:'';         
        $start = $limit*$page - $limit; 
        $start = ($start<0)?0:$start; 

        $where = ""; 
    $searchField = isset($_POST['searchField']) ? $_POST['searchField'] : false;
        $searchOper = isset($_POST['searchOper']) ? $_POST['searchOper']: false;
        $searchString = isset($_POST['searchString']) ? $_POST['searchString'] : false;

        if (isset($_POST['_search']) == 'true') {
            $ops = array(
                'eq'=>'=',

            );

        if($searchOper == 'cn' || $searchOper == 'nc' || $searchOper == 'in' || $searchOper == 'ni') $searchString = '%'.$searchString.'%';

        $where = "$searchField $ops '$searchString'"; 

    }

    if(!$sidx) 
        $sidx =1;

    $count = $this->db->count_all_results('table1'); 
    if( $count > 0 ) {
        $total_pages = ceil($count/$limit);    
    } else {
        $total_pages = 0;
    }

    if ($page > $total_pages) 
        $page=$total_pages;

            $i++;
        }

    echo json_encode($responce);
