Easily integrate ezPDF (a.k.a pdf-php) into CodeIgniter Framework

Got another spare time, so, another simple tips for you. Last post I already show how to easily integrate PHPExcel in CodeIgniter so you’ll be able to create downloadable XLS report easily. We will complete our CodeIgniter reporting capability by adding PDF output feature. (Yeah, I know PHPExcel can also create a PDF output, but it sucks big, the table is badly formatted)

Why ezPDF (now pdf-php)?

Well, there’s already a guide for integrating TCPDF and DOMPDF into CodeIgniter so I present you another option by using ezPDF (pdf-php)

What’s ezPDF not good for?

Don’t use ezPDF if you are planning to use CSS or HTML codes to style your PDF. As far as I know, ezPDF does not offer easy way to parse CSS or HTML (more like it doesn’t support it). I’m not saying that you can’t style your text, in fact, some primitive text styling is supported, such as: <b>,<i>,<u>. Please read ezPDF readme file to comprehend what ezPDF has and hasn’t.

What’s ezPDF good at?

Graphic functionality, drawing (line, curve, ellipse, box, polygon), advance page numbering, paging function, automatic table-of-content generation. (On my test, ezPDF/pdf-php failed to insert a PNG image with transparency/alpha-channel rendering corrupted PDF file)

  • Create pdf-php folder in your application/third_party/ folder (let’s separate it from PHPExcel). Extract fonts folder, class.pdf.php and class.ezpdf.php inside your pdf-php folder.
Files and folder need to be extracted from ezPDF

You only need to extract these files and folder

Your application/third_party/ folder will look like this

codeigniter application/third_party structure

codeigniter application/third_party/pdf-php/ structure with ezPDF .zip content extracted there

  • Create Pdf.php inside your application/libraries/. We will name our library as Pdf class. Here’s the full library code:

Your application/libraries/ folder will look like this:

codeigniter application/libraries/ structure

codeigniter application/libraries/ structure with our new ezPDF/pdf-php library

  • It’s done. This is example on how to use our new ezPDF/pdf-php library (this code is inside a function within a controller):

Example PDF output will be like this:

codeigniter and ezPDF output result

Example ezPDF output from above codes

On above example, I show you how to:

  • call the library, select paper size, paper orientation, paper color
  • select font type, and font size
  • insert a PNG image into the PDF
  • create a table from database
  • finally, force user to download the PDF file with specific file name

Once again, for more ezPDF/pdf-php features, please read the readme on your ezPDF/pdf-php download.
