  EMBEDDING FLASH article | 17.06.2006 | print There seems to be a lot of confusion about the code needed to properly embed Flash objects within a website: it's the most frequently asked question at this site's forum. The rise of profiling sites like Myspace (who filter lots of codes) and the recent Eolas patent enforcement have thrown even more confusion into the mix. In this article, I'll try to clearly align the best options for Flash embedment. I'll also mention the most common pitfalls, and their workarounds. Let's start with the most common way to embed Flash in a website, with the code that is exported from the Flash authoring tool when one chooses to publish a file. In this example, we choose to embed mp3player.swf, which resides in the same directory as the HTML file in which the code is put. The code will consist of two parts, object and embed. The object part is used by Microsoft's Internet Explorer and the embed part is used by, well, all other browsers. Because of this twofold, all parameters are also listed twice. <object width="250" height="400" classid="clsid:d27cdb6e-ae6d-11cf-96b8-4… codebase="http://fpdownload.macromedia.c… shockwave/cabs/flash/swflash.cab#version… <param name="movie" value="mp3player.swf" /> <embed src="mp3player.swf" width="250" height="400" type="application/x-shockwave-flash" pluginspage= "http://www.macromedia.com/go/getflashpl… /> </object>Of these parameters, the most important one is the movie (or src in the embed part). This contains the location of the SWF file to include, here mp3player.swf. If the SWF file resides in another directory, we can point to it with a relative path (eg. "../flash/mp3player.swf" or an absolute path (eg. "http://www.myserver.com/flash/mp3player… The width and height parameters comply with the width and height of the SWF in pixels, but they can also be entered as a percentage of the document's size (eg: width="100%"). Last, the classid and codebase parameters (type and pluginspage for embed) tell the browsers what type of plugin is needed and where it can be downloaded. Extra Parameters The code listed above uses the minimum amount of parameters needed to properly embed the SWF file. There are a lot of other parameters available though. Each of these parameters is added to the code in the same way the SWF URL is listed; with an extra <param name="paramName" value="paramValue" /> line for the object part and with a single paramName="paramValue" for the embed part. The entire list of parameters can be found at Adobe's website, but let's show the most interesting ones here: bgcolor (#rrggbb): set the SWF's background color using a hexadecimal value. menu (true, false): show or hide the rightclick menu. quality (low,medium,high): the rendering quality of the SWF. scale (showall, noborder, exactfit): how the SWF should scale in the HTML block. wmode (transparent, opaque): set the background of the SWF transparent or not. Let's say we want to show our SWF movie with a red background, without rightclick menu and at low quality. The embed code will then end up like this: <object width="250" height="400" classid="clsid:d27cdb6e-ae6d-11cf-96b8-4… codebase="http://fpdownload.macromedia.c… shockwave/cabs/flash/swflash.cab#version… <param name="movie" value="mp3player.swf" /> <param name="bgcolor" value="#ff0000" /> <param name="menu" value="false" /> <param name="quality" value="low" /> <embed src="mp3player.swf" width="250" height="400" bgcolor="#ff0000" menu="false" quality="low" type="application/x-shockwave-flash" pluginspage= "http://www.macromedia.com/go/getflashpl… /> </object>Flashvars By now, one more extremely handy parameter remains to be discussed. It's the parameter flashvars, which allows you to send variables to the SWF file on startup. All of my Flash scripts offer the possibility of receiving flashvars, making them easy to customize and reuse (a list of all supported flashvars can be found in the readme.html files of my script's downloads). Our example's mp3player.swf accepts three flashvars: file (url): the location of an mp3 file or xml playlist file. config (url): the location of an xml configuration file. autostart (true, false): set the mp3player to automatically start or not. Flashvars have to be entered in HTML as a single string, with an "=" symbol separating the flashvar's name and value and with an "&" symbol separating subsequent flashvars. So when we want to use our mp3player.swf to automatically play the file my_cool_song.mp3, we need to enter the following embed code: <object width="250" height="400" classid="clsid:d27cdb6e-ae6d-11cf-96b8-4… codebase="http://fpdownload.macromedia.c… shockwave/cabs/flash/swflash.cab#version… <param name="movie" value="mp3player.swf" /> <param name="menu" value="false" /> <param name="quality" value="low" /> <param name="bgcolor" value="#ff0000" /> <param name="flashvars" value="file=my_cool_song.mp3&autostart=t… /> <embed src="mp3player.swf" width="250" height="400" menu="false" quality="low" bgcolor="#ff0000" flashvars="file=my_cool_song.mp3&autosta… type="application/x-shockwave-flash" pluginspage= "http://www.macromedia.com/go/getflashpl… /> </object>Flashvars Pitfalls Two major pitfalls populate the road to flashvars success. The first is relative linking of imported files. When relatively linking to imported files (as we did in the previous block of code with the mp3 file), you should always start from the location of the HTML file in which the SWF is embedded. So, in the previous example, if the SWF was to be put in a subdirectory, the flashvar pointing to the MP3 file would remain to be file=my_cool_song.mp3 and not file=../my_cool_song.mp3! Again, there's an exception: the path of FLV files should be given relatively from the SWF file. In order to prevent confusion, you can always point to files with the absolute URL (including the http://www part). The second pitfall concerns the importing of XML files. Due to security restrictions, Flash can only import XML files if they reside on the same domain as the SWF file. So, in our mp3player example, if the mp3player.swf is located in the domain www.myserver.com, then the imported playlist.xml or config.xml should also reside on www.myserver.com. This restriction only applies to XML files, you can happily import MP3 or FLV files from different domains than your own. There are two workaround around this feature (it's not a problem). The first one can be used if you're the owner of the domain on which the XML file resides. You can put a small file, called crossdomain.xml, in the root of your website. The file contains a list of domains that are granted access to the XML files from that domain. This technote contains more information about the use and structure of crossdomain.xml files. In the most extreme case, you can grant SWF's from all domains access to your website's XML files, in which the crossdomain.xml file will look like this: <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/ cross-domain-policy.dtd"> <cross-domain-policy> <allow-access-from domain="*" /> </cross-domain-policy>The second workaround for this security restriction is to loop the XML file through a small serverside script that resides on your own server. An example of such a script in PHP can be found in the extras/external_feeds/ folder of my mp3player download, in which case it is used to load podcasts from an external site into your mp3player. MySpace (and other profile sites) For embedding Flash files on a regular website, the previous examples should be all you need. For embedding on profile sites (like MySpace), an extra problem arises since these sites filter the object tag. An embed-only approach will do the job. Also, these profile sites don't allow you to upload files on their own server, so you'll have to look out for an external server to store your files on. Just remember to put at least the SWF and XML files at the same server, and refer to all files (SWF, XML and MP3/FLV/JPG) with a full pathname. <embed src="http://www.myserver.com/mp3player.s… width="300" height="300" type="application/x-shockwave-flash" pluginspage= "http://www.macromedia.com/go/getflashpl… flashvars="config=http://www.myserver.co… file=http://www.myserver.com/playlist.xm… scale="showall" name="index" /> </embed>Eolas, UFO & SWFObject An extra embedment problem arised a couple of months ago, after a small company named Eolas filed (and won) a lawsuit against Microsoft. Eolas enforced a patent on automatically embedding and interacting with external applications (like Flash) in webpages. As a result, Microsoft updated Internet Explorer: you'll see a grey border appearing around a Flash object when you move your mouse over it. Before interacting with it, you first have to click once to activate it. No doubt this patent is an example of one that should never have been approved. But it has, and you'll have to find a way to get around it (if you don't want to confuse your visitors with grey borders and extra clicks). Luckily, there is a way. It involves a bit of javascripting, and two of these scripts (with essentially the same functionality) are SWFObject (by Geoff Stearns) and UFO (by Bobby van der Sluis). I'll put up an example of our mp3player.swf with UFO. First upload ufo.js to your server and include it in the section of your website: <script type="text/javascript" src="embed/ufo.js"> </script>Second, give the HTML element in which the SWF should display a unique id: <div id="flashbanner"> this text will be replaced by the SWF. </div>Third, instantiate an UFO object below the named HTML element, and put all parameters in there (for a full list of parameters, read the UFO Website): <script type="text/javascript"> var FO = { movie:"upload/mp3player.swf", width:"300",height:"250",majorversion:"7… flashvars:"config=config.xml&file=playli… }; UFO.create(FO, "flashbanner"); </script>The UFO instance will create the code needed to embed the mp3player.swf. It sets it's dimensions to 300 by 250 pixels and also sends it Flashvars for the config and file variables. Last, the instance replaces the text by the SWF, so we can see a Flash movie directly embedded in our page, without borders and confusing clicks!
