kandi X-RAY | wkpdf Summary

wkpdf is a Ruby library typically used in Editor, Document Editor, macOS applications. wkpdf has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Command line tool for rendering HTML to PDF using WebKit and RubyCocoa on Mac OS X. Although there are plenty of browsers available for Mac OS X, I could not find a command-line tool that allows for downloading a website and storing the rendered website as PDF. This was my motivation for creating wkpdf. The application uses Apple WebKit for rendering the HTML pages, thus the result should look similar to what you get when printing the webpage with Safari.

How to bulk generate PDF from HTML templates ready for double-sided printing in PHP?

QUESTION

How to bulk generate PDF from HTML templates ready for double-sided printing in PHP?

Asked 2018-Aug-16 at 16:17

I've been struggling with this for a while and feel helpless. Prestashop uses tcpdf to generate invoices and delivery slips from HTML templates filled using Smarty. We are working on updating the invoice design and found tcpdf to be lacking in CSS support. After some research we settled for wkhtmltopdf as the right tool from converting the HTML/CSS templates to PDF.

The problem

The store has a feature for exporting multiple invoices into a single PDF. Using TCPDF I was able to make the batch file ready for double sided printing by inserting a blank page after each invoice that had odd number of pages before the file was generated. But now that we switched to wkhtmltopdf I cannot achieve the same result.

The crucial problem is that while wkhtmltopdf allows for the usage of multiple HTML templates there seems to be no reliable way to determine the number of pages they are each going to have before the file is generated. The header and footer templates can receive the page count that the invoice ends up being but they are separate from the main content and therefore I cannot insert a page break accordingly.

I've also tried to calculate the height of the content / PDF page height but there were various issues with that once I started exporting multiple templates (worked alright with a single template). This approach isn't great either because inserting a blank page into the content itself causes the footer to appear on the new page as well which is not what I want.

My best attempt

The only way I've figured out that could get me around these issues is very inefficient. Each time a template is added to the batch I could pre-generate it using a separate instance of a wrapper for wkhtmltopdf, get the temporary file name, determine how many pages it has using pdfinfo and add a blank HTML template to the main instance accordingly. Here's a draft of a function to get the number of pages of the last template added (from a class that extends the wrapper, based on some other pdfinfo questions I found on SO):

Unfortunately wkhtmltopdf is the library, which is written in C language and we can not dynamically add one page on the fly like in PHP libraries.

Citate from your comment: Due to number of items ordered or ammount of customer data each invoice can be anywhere from 1 to 3 pages long.

And because of this we can not precalculate the number of pages and write it to a database.

I think you have only one possibility / solution: you have to write behind each invoice a blank page and after the whole PDF was generated you have to edit it with free PHP library like FPDI. In combination with FPDI it is even possible to edit PDF documents.

By PDF editing you could delete all blank pages which you do not need if they starts with odd page number (like 3, 5, etc.). And in FPDI you have the possibility to detect a page number. It is much faster than the solution which you use now.

And the blank(or empty) pages you could detect on content length with FPFI like follows:
