帮助在 jQuery-ajax 中调试我的代码！？

Question

为什么我的代码在点击按钮提交并点击链接搜索后出现此错误：
我使用codeigniter。

An error has occured:
[object Object]
error

这是我的 Tour_foreign->CI_Controller：

function search_customer(){ 
    $customer_number = $this->input->post('customer_number');
    $query = $this->db->get_where('customer', array('customer_number' => $customer_number));
    if($query->num_rows()==0){
                echo '0';
            }else{
                $data = array();
                foreach ($query->result() as $row)
                {
                   $data[] = $row;
                }
                echo json_encode($data);
            }
    }

function insert_customers(){
    $customer_number = "";
    for($i = 0; $i < 10; $i++)
    $customer_number .= mt_rand(0, 9);

        $useradmin = $this->session->userdata('login');

        $nameadmin = $query->nameadmin;
        $lastnameadmin = $query->lastnameadmin;
        /*////////////////////////////////////*/
    $data = array (

当我尝试使用此脚本时，我在萤火虫的控制台中看到以下错误： NetworkError: 500 内部服务器错误

这就是出现错误的原因。修复服务器部分。 尝试清理 search_customer() 函数中的所有代码并查看它是否运行。如果这个方法永远不会被执行，那么问题就出在你的框架之外吗？

然后，逐行查看服务器上发生了什么。查询可能有问题？但通常错误 500 是当您遇到 mod_rewrite 问题时。
