PHP TCPDF 多个 WriteHTML() 不工作

Question

我编写了一些代码来创建报告，然后使用 TCPDF 将其导出为 .PDF。我想将报告的不同部分发送到邮件，因此我需要多次使用 WriteHTML() 函数来创建多个 pdf 文件并将它们保存在特定目录中。

    $parts=explode("<div class='subTable'>",$html);
    pdf->writeHTML($html, true, false, false, false, '');
    $pdf->Output('exmpl/example_045.pdf', 'I');
    $pdf->Output('exmpl/example_046.pdf', 'F');
    $pdf->writeHTML($parts[2], true, 0, true, 0);
    //Close and output PDF document
    $pdf->Output('exmpl/example_048.pdf', 'F');

虽然我尝试将两个不同的文件导出到目录 exmpl ，但我实际上得到的只是一个文件 (example_046.pdf)。

我必须提到我可以多次使用 Output() 并且我已经做过这样的事情，但是我不能多次使用 writeHTML()。

任何解决方案将不胜感激，提前致谢 !

Answer 1

你的问题是在 $pdf->Output('exmpl/example_045.pdf', 'I') 之后，好像脚本到此结束。为什么要拍到文件头。

你不能拍摄两个不同的头文件，如果你想生成两个不同的 pdf，我建议你使用函数输出字符串

$pdf->Output('', 'S');

因此文件系统上的这两个文件保存并拍摄。压缩文件并拍摄包含两个pdf的压缩文件头。

更新

在您的情况下，我会使用类似的方法:

function createPDF($html, $type, $filename, $output)
    {
        $pdf = new TCPDF();
        //... code ...
        if($type == "all"){
            $pdf->writeHTML($html, true, false, false, false, '');
        } elseif($type == "partial"){
            $parts = explode("<div class='subTable'>", $html);
            $pdf->writeHTML($parts[2], true, 0, true, 0);
        }
        $pdf->Output('exmpl/' . $filename . '.pdf', $output);
    }

createPDF($html, "partial", "example_048", "F");
createPDF($html, "all", "example_046", "F");
createPDF($html, "all", "example_045", "I");
