我可以知道为什么我在控制台上收到此错误消息（500（内部服务器错误））。桌上没有任何东西出现。我想根据将使用JavaScript发送的信息在表格上显示数据

答案 0 :(得分：1)
首先捕获ajax在控制器中发送的数据，如
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');
}
}
秒您的模型应使用传递给模型方法的参数
来接收数据但您没有通过任何论据
它应该是这样的：
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 $query->result();
}
而不是使用$ _POST在printData中使用$ data（$ data = array（））
答案 1 :(得分：0)
首先在控制器中获取数据：
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'),
);
$this->user->printData($data);
$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');
}
}
您将获得模型中的数据：
public function printData($data){
//your code here
}
