Export /Import tools to include widget contents
I'd like to see the built-in export and import (wxr) format to support widgets and their contents. Widgets have become very important to the setup of any WordPress site and its a shame that these can't easily be moved from one site to another.
I think this is very useful to anyone, but also in my case I'm a theme designer and want to be able to include widgets in my page samples wxr file for easy theme setup.
I agree, though its a hard one as the way plugin's data is stored varies from plugin to plugin. I guess it would be possible if the plugin uses only the Settings API.
That's a good point about third-party widgets potentially saving data in different ways. It would be fine to just support the normal Settings API as you suggest. I believe there is a common location that a specific widget instance's data is stored as well... like the wp_cache. As long as all the core WordPress widgets were supported, that would be fine.
Then if a 3rd-party widget stores its data in the same way as the core widgets do, then they should work as well.
For example, I wrote my own recent comments and recent posts widgets and modeled them directly off the core widgets. So they would probably export and import just fine.
yep, and now that I think of it, if a plugin uses a custom table, the export code could provide an action to hook to so the plugin can add its own data to the exported xml file.
