我是 PHP 和 JEasy UI 的新手。我实际上正在运行 JEasy UI Grid 的演示应用程序。而我没有从 Php 文件中获取数据到网格。

任何想法或建议请...！

以下是我的代码：

索引.php

要从数据网格中获取数据，您需要像这样编写代码

   public function get_user(){

    /*Default request pager params from jeasyUI*/
    $offset = isset($_POST['page']) ? intval($_POST['page']) : 1;
    $limit  = isset($_POST['rows']) ? intval($_POST['rows']) : 10;
    $search = isset($_POST['search']) ? $_POST['itemid'] : '';
    $offset = ($offset-1)*$limit;

    //change this line to yours
    $data   = $this->user_model->get_user($offset,$limit,$search); 
    $i  = 0;
    $rows   = array(); 
    foreach ($data ['data'] as $r) {

       $rows[$i]['first_name'] = $r->first_name;
       $rows[$i]['last_name'] = $r->last_name;
       $rows[$i]['phone'] = $r->phone;
       $rows[$i]['email'] = $r->email;

     $i++;
    }

    //keys total & rows is required on jEasyUI
    $result = array('total'=>$data['count'],'rows'=>$rows);
    echo json_encode($result);
 }
