请问为什么我在控制台上收到此错误消息(500(内部服务器错误))。 table 上什么也没有出现。我想在表格上显示使用 JavaScript 发送的信息中的数据

最佳答案
首先在 Controller 中捕获ajax发送的数据，如下所示
function getPrintData(){
if($this->session->userdata('logged_in'))
{
$data = array('dateFrom' => $this->input->post('dateFrom'),
'dateTo' => $this->input->post('dateTo'),
'idsearch' => $this->input->post('idsearch'),
);
$session_data = $this->session->userdata('logged_in');
$data['email'] = $session_data['email'];
$data['idsearch'] = $this->user->printData($data);
$data['dateFrom'] = $this->user->printData($data);
$data['dateTo'] = $this->user->printData($data);
$data['query'] = $this->user->getSearch($data);
$data['print'] = $this->user->printData($data);
}
else
{
//If no session, redirect to login page
redirect('login', 'refresh');
}
}
第二，您的模型应该使用传递给模型方法的参数接收数据
但你没有传递任何参数
应该是这样的:
function printData($data = array()){
$db2 = $this->load->database('otherdb', TRUE);
$db3 = $this->load->database('pan', TRUE);
$sql = "SELECT c.id,p.name AS 'Pubname',section,pubdate,byline,headline,subheadline,TEXT,AREA,ave,linkedto,thumimage,pagenum,clipuploadpath, c.articleref,pdf,docpath,articlepartnumber,articlepartscount,keyword,logo,p.description AS 'PubInfo',circulation,m.description AS 'MediaType', r.description FROM pearhpmszm_db5.Allocation a JOIN pearhpmszm_db5.clip c ON c.id = a.idclip LEFT JOIN pearhpmszm_db3.Publication p ON c.pubid = p.id LEFT JOIN pearhpmszm_db3.ABC ab ON ab.idpub = p.id LEFT JOIN pearhpmszm_db3.mediatype m ON m.id = p.idmediatype LEFT JOIN pearhpmszm_db3.Region r ON r.id = p.idregion WHERE a.idsearch IN ('".'$data["idsearch"]'."') AND c.pubdate BETWEEN '".'$data["dateFrom"]'."' AND '".'$data["dateTo"]'."'";
$query = $this->db->query($sql);
return $query->result();
}
不要使用 $_POST，而是使用 printData($data = array()) 中的 $data
关于javascript - 使用 ajax 和 codeigniter 通过 Controller 将数据发送到模型，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38326791/
