I am using CakePHP 2.xx and the following component -
https://github.com/segy/Mpdf to render pdf's.
I have 2 Controller methods, the first method *request_pdf* calls a second
method *send_pdf* in the same Controller. The second method creates and
saves a pdf to file, and will then email the pdf (but for simplicity I have
omitted this part of the code).
Once the second method *send_pdf* finishes creating the pdf control should
be passed back to the first method *request_pdf* where it should then
render on screen the view file in *view/Documents/request_pdf*.
The pdf correctly saves to the TMP directory, BUT when *request_pdf* renders
in the browser, it renders the pdf on screen. The saving of the pdf seems
to interfere with the rendering of the view.
Here is my Controller code
App::uses('AppController', 'Controller');
App::uses('CakeEmail', 'Network/Email');
class DocumentsController extends AppController {
public $components = array('Mpdf');
// --------------------------------------------------
// beforeFilter
// --------------------------------------------------
public function beforeFilter()
{
parent::beforeFilter();
}
function request_pdf()
{
$this->send_pdf();
// have also tried this as described by the author of Mpdf component
// $result = $this->requestAction(array('action' => 'send_pdf/'),
array('return', 'bare' => false));
}
function send_pdf()
{
$this->layout = null;
$this->Mpdf->init();
$response = $this->render('send_pdf');
$thebody = $response->body();
$this->Mpdf->WriteHTML($thebody);
$this->Mpdf->Output(TMP.'requested_pdf.pdf', 'F');
// have also tried this
// $this->Mpdf->setFilename(TMP.'requested_pdf.pdf');
// $this->Mpdf->setOutput('F');
}
}
I'm sure that it is something simple that I'm over looking here regarding
the rendering of the original view, but I can't work it out.
I have also tried calling different methods in both the first and second
methods without success,
$this->layout
$this->view
$this->viewPath
$this->render
$This->autoRender
If I remove $this->layout = null from send_pdf then I get both the pdf AND
view from *request_pdf*rendered on the screen overlaying each other.
All help appreciated.
