加载 Codeigniter 的视图文件时，DOM PDF 不起作用

发布于 2024-12-23 17:11:46 字数 1633 浏览 2 评论 0原文

我正在尝试使用 DOM pdf 和 Codeigniter 创建 PDF 文件。我的 Controller 中有以下脚本，并且我将 DOM 文件夹保留在我的控制器中。但是当我运行脚本时，我收到致命错误消息。

但是当我将模型中的值发送到控制器中的 DOMPDF 的 $html 时..我可以生成 pdf。

您能帮我解决这个错误吗？

    include_once('dompdf/dompdf_config.inc.php'); 
    $html= $this->load->view('view_pdf');
    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->set_paper("a4", "landscape" ); 

    $dompdf->render();
    $dompdf->stream("my_pdf.pdf", array("Attachment" => 0));

这是我的查看文件；

<html>
 <head>
<style>
    #header { position: absolute; left: 0; top: -50px; right: 0; height: 140px; text-align:  center;  }
    #footer {position: fixed ; left: 0px; bottom: -20px; right: 0px; height: 30px; font-size:10; }
    #footer .page:after { content: counter(page, upper-roman); }


        #table-6 {
        width: 100%
        border: 1px solid #B0B0B0;
        }
        #table-6 tbody {
        /* Kind of irrelevant unless your .css is alreadt doing something else */
        margin: 0;
        padding: 0;
        border: 0;
        outline: 0;
        font-size: 100%;
        vertical-align: baseline;
        background: transparent;
        }


        #table-6 td {
        padding: 3px 10px;
        font-size: 12px;
        font-weight: normal;
        text-align:center;
        }
        #table-6 tr:nth-child(even) {
        background: #F2F2F2;
        font-size: 12px;
        font-weight: normal;
        }




 </style>

  </head>

I am trying to create PDF file using DOM pdf and Codeigniter. I have the following script in my Controller and I have kept the DOM folder inside my controller . But when I run the script I get fatal error message.

But when I send a value from my model to DOMPDF's $html which is in my controller .. I can generate the pdf.

Could you please kindly help me how to get rid of this error?

    include_once('dompdf/dompdf_config.inc.php'); 
    $html= $this->load->view('view_pdf');
    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->set_paper("a4", "landscape" ); 

    $dompdf->render();
    $dompdf->stream("my_pdf.pdf", array("Attachment" => 0));

This is my View File ;

<html>
 <head>
<style>
    #header { position: absolute; left: 0; top: -50px; right: 0; height: 140px; text-align:  center;  }
    #footer {position: fixed ; left: 0px; bottom: -20px; right: 0px; height: 30px; font-size:10; }
    #footer .page:after { content: counter(page, upper-roman); }


        #table-6 {
        width: 100%
        border: 1px solid #B0B0B0;
        }
        #table-6 tbody {
        /* Kind of irrelevant unless your .css is alreadt doing something else */
        margin: 0;
        padding: 0;
        border: 0;
        outline: 0;
        font-size: 100%;
        vertical-align: baseline;
        background: transparent;
        }


        #table-6 td {
        padding: 3px 10px;
        font-size: 12px;
        font-weight: normal;
        text-align:center;
        }
        #table-6 tr:nth-child(even) {
        background: #F2F2F2;
        font-size: 12px;
        font-weight: normal;
        }

根据 CodeIgniter 关于视图的文档，您必须修改对 load->view 的调用() 以便数据作为字符串返回到控制器，而不是推送到 Web 浏览器。尝试按如下方式修改控制器代码：

include_once('dompdf/dompdf_config.inc.php');
$html= $this->load->view('view_pdf','',true);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper("a4", "landscape" );

$dompdf->render();
$dompdf->stream("my_pdf.pdf", array("Attachment" => 0));

我所做的唯一更改是将必要的参数添加到 $this->load->view()。

（我不使用 CodeIgniter。CI 用户有什么要补充的吗？）

According to the CodeIgniter documentation on views you have to modify your call to load->view() so that the data is returned as a string to the controller rather than pushed to the web browser. Try modifying your controller code as follows:

include_once('dompdf/dompdf_config.inc.php');
$html= $this->load->view('view_pdf','',true);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper("a4", "landscape" );

$dompdf->render();
$dompdf->stream("my_pdf.pdf", array("Attachment" => 0));

The only change I made was to add the necessary parameters to $this->load->view().

(I don't use CodeIgniter. Do any CI users have anything to add?)

include_once('dompdf/dompdf_config.inc.php'); 
$this->load->view('view_pdf');
$html = $this->output->get_output();
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper("a4", "landscape" ); 
$dompdf->render();
$dompdf->stream("my_pdf.pdf", array("Attachment" => 0));
