Creating PDF Helper for CakePHP 2.0 using TCPDF

Question

I'm currently working on a PDF view for my cake application and found this tutorial.

http://www.startutorial.com/articles/view/how-to-create-pdf-helper-with-tcpdf

But currently I'm struggling over this error message:

Notice (8): Undefined variable: pdf [APP\View\Pdfs\index.ctp, line 2]
Notice (8): Trying to get property of non-object [APP\View\Pdfs\index.ctp, line 2]
Fatal error: Call to a member function addPage() on a non-object in \app\View\Pdfs\index.ctp on line 2

Can anyone help me out, what I have to adapt to CakePHP 2.0

Answer 2

For Cake 2.1, use this code:

<?php
    $this->Pdf->core->addPage('', 'USLETTER');
    $this->Pdf->core->setFont('helvetica', '', 12);
    $this->Pdf->core->cell(30, 0, 'Hello World');
    $this->Pdf->core->Output('example_001.pdf', 'D');
?>
