Magento PDF 发票内容布局问题

Question

我根本不擅长PDF。我在下面添加了两部分，称为“发票注释和订单注释”。我遇到的问题是我无法将这两个部分放在一个好的单元格中。当我尝试诸如 $pdf->Cell 等时，我只是看到可怕的白屏。由于某种原因，似乎只有 drawText 可以渲染文本。此外，评论也延伸到了 PDF 页面之外。我尝试输入换行符但没有成功。我猜是因为注释是数组。任何帮助都会很棒。

                //Get product image and resize it

我已经为您完成了发票注释部分，以便您能够将相同的技术应用于订单注释。我在我的沙箱上测试了它并且它有效。您可以将 $textChunk = wordwrap($comm->getData('comment'), 120, "\n"); 行中的 120 值更改为最适合您发票的方式。我在内部发票注释中添加了一个表格标题，但您可以根据需要将其删除。

/*************************** This Is The Invoice Comments ***********************************/

    $this->_setFontRegular($page, 10);

    // Begin table header
    $page->setFillColor(new Zend_Pdf_Color_RGB(0.93, 0.92, 0.92));
    $page->setLineColor(new Zend_Pdf_Color_GrayScale(0.5));
    $page->setLineWidth(0.5);
    $page->drawRectangle(25, $this->y, 570, $this->y -15);
    $this->y -= 10;
    $page->setFillColor(new Zend_Pdf_Color_RGB(0, 0, 0));
    // end table header


    $_tempY = $this->y;

    $commentsCollection = $invoice->getCommentsCollection(true);

    $internalcomments = "Internal Invoice Comments";
    $page->drawText($internalcomments, 35, $this->y, 'UTF-8');

    $this->y -= 15;

    foreach($commentsCollection as $comm)
    {
            $textChunk = wordwrap($comm->getData('comment'), 120, "\n");
            foreach(explode("\n", $textChunk) as $textLine){
                    if ($textLine!=='') {
                            $page->drawText(strip_tags(ltrim($textLine)), 35, $this->y, 'UTF-8');
                            $this->y -= 15;
                    }
            }

     }
