DOMPDF,我不能创建两个pdf

Question

当我尝试一次创建两个pdf时,它会抛出错误......

致命错误:未捕获异常'DOMPDF_Exception',消息'找不到块级父级.不好.' 在第38行的C:\ wamp\www\si2i\application\libraries\dompdf\include\inline_positioner.cls.php中(!)DOMPDF_Exception:找不到块级父级.不好.在第38行的C:\ wamp\www\si2i\application\libraries\dompdf\include\inline_positioner.cls.php中

这是代码:

$this->load->library('pdf');
                    $this->pdf->set_base_path($data['path']);
                    $this->pdf->load_view('adm/invoice/si2i',$data);
                    $this->pdf->render();
                    $output = $this->pdf->output();
                    file_put_contents("uploads/invoice/invoice_".$invoice_file_name.".pdf", $output);

$this->load->library('pdf');
                    $this->pdf->set_base_path($data['path']);
                    $this->pdf->load_view('adm/invoice/si2i',$data);
                    $this->pdf->render();
                    $output = $this->pdf->output();
                    file_put_contents("uploads/invoice/invoice_".$invoice_file_name.".pdf", $output);

请帮帮我..

提前致谢...

我刚遇到同样的问题.解决方案是codeigniter pdf库$ this-> load-> library('pdf'); 创建一个每次调用的DOMPDF实例,但是该类本身不能正常清理,因此如果需要生成多个pdf,则会崩溃.

解决方案是根据需要手动实例化DOMPDF类.不要使用codeigniter pdf包装器.

//require at the top of our script
require_once(APPPATH .'libraries/dompdf/dompdf_config.inc.php');

//get the html first (base dompdf cant do the combined load/render)
$view = $this->load->view("viewname", $viewData, true);
//create a new dompdf instance (this is the crucial step)
$this->pdf = new DOMPDF();
//render and output our pdf
$this->pdf->load_html($view);
$this->pdf->render();
$pdf = $this->pdf->output(array("compress" => 0));
file_put_contents("some/file/path.pdf", $pdf );
