if ($form->isvalid()) {         // create event ticket         $pass = new eventticket("1234567890", "the beat goes on");         $pass->setbackgroundcolor('rgb(60, 65, 76)');         $pass->setlogotext('apple inc.');          // create pass structure         $structure = new structure();          // add primary field         $primary = new field('event', 'the beat goes on');         $primary->setlabel('event');         $structure->addprimaryfield($primary);          // add secondary field         $secondary = new field('location', 'moscone west');         $secondary->setlabel('location');         $structure->addsecondaryfield($secondary);          // add auxiliary field         $auxiliary = new field('datetime', '2013-04-15 @10:25');         $auxiliary->setlabel('date & time');         $structure->addauxiliaryfield($auxiliary);          // add icon image         $icon = new image('appassbundle/resources/images/icon.png', 'icon');         $pass->addimage($icon);          // set pass structure         $pass->setstructure($structure);          // add barcode         $barcode = new barcode(barcode::type_qr, 'barcodemessage');         $pass->setbarcode($barcode);          // create pass factory instance         $factory = new passfactory('pass.dk.mcoupons.mcoupon', '9w6x83aq63', 'ka innovation aps', '%kernel.root_dir%/resources/certificates/certificate.p12', 'hestmink09', '%kernel.root_dir%/resources/certificates/applewwdrca.pem');         $factory->setoutputpath('%kernel.root_dir%/logs/pkpass');         $factory->package($pass);         //$em = $this->getdoctrine()->getentitymanager();         //$em->persist($task);         //$em->flush();         echo 'pass generated ';         return $this->render('apbappassbundle:default:index.html.twig');      } 

but giving me error

splfileobject::__construct(appassbundle/resources/images/icon.png): failed open stream: no such file or directory 500 internal server error - runtimeexception

i have tried different ways give path failed. here hierarchy or folder structure images stored

try

 $icon = new image('%kernel.root_dir%/appassbundle/resources/images/icon.png', 'icon'); 

or maybe:

$iconpath = $this->get('kernel')->getrootdir().'/appassbundle/resources/images/icon.png'; $icon = new image($iconpath, 'icon'); 

or similar, don't see whole structure of project.
