Iframe Problem With Firefox

[Obi1-Cannabis]

heyas,i'm using an iframe to show a php page, this page gets a pdf file from database and displays it.this iframe works alright in ie7, opera9 and chrome (these are the ones i've tried) but in firefox the iframe just stay white and show nothing.i've tried to use object instead, at first it works with firefox but then it brakes the page and gives error making me close firefox, and it does not work with other browsers.is there any solution to make this work ok?

Are you sending the correct header with PHP?

header("Content-type: application/pdf");

There are various differences in the way browsers display iframes, have you got a link to the page or some code we can look at, makes problem solving a lot easier;)

yes i'm sending the corect header with php.and here is the code:xHTML & smarty

{foreach item=idioma from=$idiomas key=idiomaKey}   <div>   <iframe class="media" id="media-{$idiomaKey}" src="{$wwwroot}/ementas/ficheiroEmenta.php?idmenu={$menu.idmenu}&ididioma={$idioma.ididioma}"></iframe>   </div>{/foreach}

PHP

require_once($_SERVER["DOCUMENT_ROOT"] . "/classes/lib/menu.inc.php");$menuObj = new Menu();$menuObj->idmenu = $_REQUEST["idmenu"];$menuObj->ididioma = $_REQUEST["ididioma"];		$file = $menuObj->GetFileMenu();		$ficheiro = $file["ficheiro"];			header("Content-type: application/pdf");			print $ficheiro;
