Compatibility with FlashObject ↑

This document is intended for users of FlashObject, a (much older) swf embedding plugin that inspired swf_fu.

You can choose to:

1) keep both. They won’t interfere and flashobject_tag will continue to use the older SWFObject 1.5 library.

2) remove FlashObject:

script/plugin remove flashobject_helper

You can also manually remove javascripts/flashobject.js

swf_fu will take over the flashobject_tag and will use the new SWFObject 2.2 library. This should not have impacts as long as:

  • your swf path is absolute (e.g. “/path/to/my_flash.swf”). If it is relative, move your swf file from ‘public/’ to the new ‘public/swfs/’ asset folder

  • you include the default javascripts (otherwise you need to include ‘swfobject’ explicitely and stop including ‘flashobject’)

  • you don’t use the javascript object before the page is loaded. SWFObject 2.2 makes the changes to the web page later

  • you don’t rely on the verify_file_exists option (it doesn’t do anything anymore)

In either case 1 or 2, you change existing calls to flashobject_tag for swf_tag at your leisure. The interface is similar and the main differences are some options name changes:

:flash_id  => :id
:variables => :flashvars
:background_color => options[:parameters][:bgcolor]

Moreover, the following defaults are gone:

:flashvars[:lzproxied]
:parameters[:scale]
:parameters[:bgcolor]
