如何修复tcpdf中的错误？
当我的报告中有1个日期时，报告正在运行。但是当我添加另一个日期（数据）时，报告显示错误。我不知道在哪里找到它。
以下是报告控制器的代码：
public function index()
{
$data["nav"]="4";
$this->load->model('report_model');
if ($this->session->userdata('position')=="Professor")
{
$data["records"]=$this->db->query("select * from tblclass WHERE CID IN (select CID from tblseatplan) AND AID=". $this->session->userdata('id'));
$this->load->view('report_view', $data);
}
else if($this->session->userdata('position')=="Department Chair")
{
$AID=$this->session->userdata('id');
$account = $this->db->query("select * from tblaccount WHERE AID='$AID'");
foreach($account->result() as $row){
$department = $row->Department;
}
$data["records"]=$this->db->query("select * from tblclass WHERE CID IN (select CID from tblseatplan) AND Course_Code_Section LIKE '%$department%'");
$this->load->view('access_department_chair_view', $data);
}
}
public function attendanceReport()
{
$this->load->library('Pdf');
$this->load->library('Pdf');
$pdf=new Pdf('L', 'mm', 'A4', true, 'UTF-8', false);
$pdf->SetTitle('Technological Institute of the Philippines');
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);
$pdf->SetAutoPageBreak(true, 15);
$pdf->SetAuthor('Author');
$pdf->SetDisplayMode('real', 'default');
$pdf->AddPage("L");
$CID=$this->input->post("CID");
$period=$this->input->post("period");
$dates=$this->db->query("SELECT date_check FROM tblattendance WHERE CID='$CID' AND period='$period'
GROUP BY date_check ORDER BY date_check ASC");
$students=$this->db->query("SELECT a.SID, s.Student FROM tblattendance a
LEFT JOIN tblstudent s ON a.SID=s.SID
WHERE a.CID='$CID' AND a.period='$period'
GROUP BY a.SID ORDER BY a.date_check ASC");
$class=$this->db->query("SELECT c.*, a.First_Name, a.Last_Name FROM tblclass c
LEFT JOIN tblaccount a ON c.AID=a.AID WHERE c.CID='$CID'");
foreach($students->result() as $s)
{
$sSID = $s->SID;
$student_at = $this->db->query("SELECT status FROM tblattendance

}
}
以下是仅有1个日期的工作报告的屏幕截图。
这是我输入2日期时的错误。
