Magento PDF Invoice Content Layout Issues - magento

Question

I am not good with PDF's at all. I have added two secions below that are commented called "Invoice Comments and Order Comments". The trouble I am having is that I cannot put these two sections in a nice cell. When I try things like $pdf->Cell and etc. I just get the dreaded white screen. For some reason it seems that only drawText works with rendering the text. Also, the comments are extending off of the PDF page. I have tried to enter line breaks with no success. I guess its b/c the comments are Arrays. Any help would be great.

Answer 1

I have completed the Invoice Comments section for you so you'll be able to apply the same technique to the Order Comments. I tested this on my sandbox and it worked. You can change the value of 120 in the $textChunk = wordwrap($comm->getData('comment'), 120, "\n"); line to be whatever works best for your Invoice. I added a table header to the Internal Invoice Comments but you can remove that if you want.
/*************************** 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;
}
}
}

P.S. Part of the new-line in Magento PDF routine was adapted from PHP + PDF Line Break. Thanks #shaune!
