加载Codeigniter视图文件时DOMPDF无法正常工作

我正在尝试使用DOM pdf和Codeigniter创建PDF文件。我的控制器中有以下脚本,我将DOM文件夹保存在控制器中。但是当我运行脚本时,我会收到致命的错误消息。

但是当我从我的模型中发送一个值到我控制器中的DOMPDF的$ html时......我可以生成pdf。

请帮助我如何摆脱这个错误?

    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>

根据CodeIgniter documentation on views,您必须修改对load-&gt; view()的调用,以便将数据作为字符串返回给控制器,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));

我做的唯一更改是将必要的参数添加到$this->load->view()

(我不使用CodeIgniter。任何CI用户都有什么要添加的吗?)

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));
