TCPDF仅显示来自DB的第一条记录，而不显示其他记录

Question

我想将视图文件转换为pdf ..查看文件有来自db的记录...但是当它渲染为pdf时，没有数据显示php变量来自哪里.. 任何人都可以提出什么问题：

在“公司”显示其显示空白pdf

之后

这是pdf创建代码：

error_reporting(-1);
                require_once('TCPDF/tcpdf.php');        
                $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
                $pdf->SetCreator(PDF_CREATOR);
                $pdf->setPrintHeader(false);
                $pdf->setPrintFooter(false);
                $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
                $pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
                $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
                $pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
                if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
                    require_once(dirname(__FILE__).'/lang/eng.php');
                    $pdf->setLanguageArray($l);
                }
                $pdf->setFontSubsetting(true);
                $pdf->SetFont('dejavusans', '', 14, '', true);
                $pdf->AddPage();
                $pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));
                $html = $this->load->view('frontend/quotes_detail_po_pdf', $data, TRUE);
                $pdf->writeHTMLCell(0, 0, '', '', $html, 0, 1, 0, true, '', true);
                ob_end_clean();
                $pdf->Output($prorder.".pdf", 'I');
