PDF Generation via DOMPDF Library

http://code.google.com/p/dompdf/

Input:

• HTML string (which could be rendered template)
• HTML File

Output

• PDF File location
• SS File
• PDF binary stream to browser

Quickly getting started

Find the ID number of a page (ie 1) and go to; /pdf/1

Customize your tempalte by copying DefaultPDF to your theme directory.

View raw output by going to; /pdf/1?show

Example usage

$pdf = new SS_DOMPDF();
$pdf->setHTML($mydataobject->renderWith('MyTemplate'));
$pdf->render();
$pdf->toFile('mypdf.pdf');

Debugging

The $pdf->streamdebug(); function is useful for quickly viewing pdfs, particularly if your browser supports displaying pdfs, rather than downloading.

You can check your html before it is converted like this:

echo $mydataobject->renderWith('MyTemplate');die();

Once this has been installed then you need to; parse your PDF templates to a .html file get dompdf to convert the saved .html file

A more advanced solution would be something like;

class CustomPage_Controller extends Page_Controller {

public function mypdf(){
	if($member = Member::currentUser()){
		Requirements::clear();
		
		if(!file_exists(ASSETS_PATH."/private")) mkdir(ASSETS_PATH."/private");
		
		require_once 'Zend/Date.php';
		$defaultDateFormat =Zend_Date::now()->toString($member->DateFormat);
		$defaultTimeFormat = Zend_Date::now()->toString($member->TimeFormat);			
		
		$content = $this->customise(array(
			'Member'	=> $member
		))->renderWith(array('pdf'));

		$filename=ASSETS_PATH."/private/current-pdf-{$member->ID}.html";
		$baseFile = preg_replace('/\\.pdf$/','',$filename);

		$fh = fopen($baseFile, "w+") or user_error("Couldn't open $baseFile.html for writing", E_USER_ERROR);
		fwrite($fh, $content) or user_error("Couldn't write content to $baseFile.html", E_USER_ERROR);
		fclose($fh);

		$dompdf = new SS_DOMPDF();
		$dompdf->load_html_file(ASSETS_PATH."/private/current-pdf-{$member->ID}.html");

		if ( isset($base_path) ) {$dompdf->set_base_path($base_path);}

		$paper = DOMPDF_DEFAULT_PAPER_SIZE;
		$orientation = "portrait";

		$dompdf->set_paper($paper, $orientation);
		$dompdf->render();
		
		
		$outfile = substr("{$member->FullName()}_{$defaultDateFormat}_{$defaultTimeFormat}", 0, 250).".pdf";

		$dompdf->stream(Convert::raw2xml($outfile));
	}	
}

/**

public function testpdf(){
	if($member = Member::currentUser()){
		Requirements::clear();
		require_once 'Zend/Date.php';

		$property=$member->SavedProperty();
		$content = $this->customise(array(

		))->renderWith(array('pdf'));
		return $content;
	}
}
