Using CakePdf data not showing - cakephp

Question

I am in a problem with CakePDF. I am using CakePHP 2.3.6. I setup everything alright, bootstrap & core files are ok.
Now, I want to generate many pdf files and download them. Downloading is ok, but when I download the files, I see that the generated pdf files say that Undefined $data, where I send $data to the view file.
Here is my Controller code:
App::uses('CakePdf', 'CakePdf.pdf');
// ...
public function createPdf($id) {
$data = $this->DBTable->find('all', array(
'conditions' => array(
'DBTable.id' => $id
)
));
$CakePdf = new CakePdf();
$path = APP . DS . 'pdf' . DS;
foreach($data as $key => $var) {
$CakePdf->template('create', 'default');
$this->set('var', $var);
$this->pdfConfig = array(
'orientation' => 'portrait',
'filename' => $var['id'] . ".pdf"
);
$CakePdf->write($path . $var['id'] . ".pdf");
}
}
Here, I am downloading the files some other way, not related to this problem, because downloading is ok. When I run this, all files are downloaded, and when I see the files, they say "Udefined var", looks like they didn't receive and variable called "$var".
I put the view file & the layout exactly where ceeram said.
What should I do now ? Please help me.

Answer 1

At last I got a solution to this. In the Controller function :
$data=$this->ModelName->find('all');
$CakePdf=new CakePdf();
$CakePdf->template('view_file','default');
$this->pdfConfig=array('orientation'=>'portrait','filename'=>$data['name']);
$CakePdf->viewVars(array('data'=>$data));
$CakePdf->write($path.$data['name'].".pdf");
Here, we have to store view_file.ctp in View/Pdf/, and default in View/Layouts/pdf/, where view_file.ctp is the view file which we want to convert in pdf, and default is the layout for this specific view file.
Here, viewVars() function passes the data to the view file, just like :
$this->set->('data',$data);
Let me know if anything is not clear here.
Thanks.
