function theme_flashnode_markup in Flash Node 5.3

Same name and namespace in other branches

2. 6.3 flashnode.module \theme_flashnode_markup()
3. 6.2 flashnode.module \theme_flashnode_markup()

Generate fallback HTML if the SWF Tools module is not available

Flash node uses SWF Tools to handle JavaScript replacement but this isn't always easy to set up. To assist users Flash node will fall back to direct HTML embedding if it can't find SWF Tools. This means Flash node will work 'out of the box' in a basic fashion, and is extended when SWF Tools is available rather than being entirely dependent upon it.

This function is called with an array of parameters that define a flashnode. See the description theme_flashnode for details.
