PHPWord 到 PDF 无法加载库

Question

我整天都在努力让它工作。现在我可以将文档另存为 .docx 文件，但我希望能够将文档另存为 PDF 我已经尝试使用 DOMPDF 和 TCPDF 但我一直收到错误 'Unable to load PDF Library' 我确认路径是正确的。我错过了什么吗？谢谢你的帮助

$rendererName = \PhpOffice\PhpWord\Settings::PDF_RENDERER_TCPDF;
$rendererLibrary = 'tcpdf.php';
$rendererLibraryPath = dirname(__FILE__) .'/plugins/tcpdf/' . $rendererLibrary;

\PhpOffice\PhpWord\Settings::setPdfRenderer($rendererName,$rendererLibraryPath);

$document->saveAs('temp.docx'); // Save to temp file
$test = \PhpOffice\PhpWord\IOFactory::load('temp.docx'); // Read the temp file
$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($test, 'PDF');
$xmlWriter->save('result.pdf');  // Save to PDF
unlink('temp.docx'); // Delete the temp file

这是抛出错误的代码

  public function __construct(PhpWord $phpWord)
{
    parent::__construct($phpWord);
    $includeFile = Settings::getPdfRendererPath() . '/' . $this->includeFile;
    if (file_exists($includeFile)) {
        /** @noinspection PhpIncludeInspection Dynamic includes */
        require_once $includeFile;
    } else {
        // @codeCoverageIgnoreStart
        // Can't find any test case. Uncomment when found.
        throw new Exception('Unable to load PDF Rendering library');
        // @codeCoverageIgnoreEnd
    }
}

这是完整的错误

Answer 1

知道所有这些，我猜答案正在改变：

$includeFile = Settings::getPdfRendererPath() . '/' . $this->includeFile;

至

$includeFile = Settings::getPdfRendererPath();

Answer 2

当我将错误打印到日志中时，我意识到它正在尝试从无效位置加载 dompdf_config.inc.php。见下文。

C:\wamp\www\cccake\app\Vendor\dompdf\dompdf.php/dompdf_config.inc.php\n

与其更改 PHPExcel/PHPWord 的 class 文件，不如在您的视图中更改配置是明智的。在 $rendererLibraryPath 中完全忽略 $rendererLibrary 解决了我的问题。我认为 PHPExcel/PHPExcel 知道如何根据您的情况选择 dompdf.php 文件 (tcpdf.php)。试试下面的代码，如果它不起作用，请告诉我们。

$rendererLibrary = 'tcpdf.php'; $rendererLibraryPath = dirname(FILE) .'/plugins/tcpdf';

Answer 3

确保在以下位置发送 DOMPDF 路径：

$domPdfPath = "..vendor/dompdf/dompdf/";
Settings::setPdfRendererName(Settings::PDF_RENDERER_DOMPDF);
Settings::setPdfRendererPath($domPdfPath); //<---

然后在 AbstractRerender 构造中，如果您回显 $this->Include 文件，您应该会看到 'dompdf_config.inc.php'

如果没有dompdf_config.inc.php文件，尝试使用dompdf 0.6.2
