[Plugin: upc0ming] Google Apps
-
Good idea for a widget, but unfortunately it doesn’t seem to return any events from a Google Apps calendar. I tried it with a shared calendar, but got no results. Trying it with a publicly shared calendar ([email protected]) works fine.
Also needs some more configuration options (specifically, number of events returned).

Looks like this does work with Google apps after all; my sharing config didn’t save like I thought it had. As for specific number of events, I modified the plugin to include this functionality. I am no PHP guru, but it does work.

Hated the styling, too; not sure why it would be done this way instead of strictly by the designer. I changed the plugin a bit so that it displays the events in an unordered list, and has a message if there are no events. I’ll paste it here in case anybody else is interested. (I also commented out the CSS/DIV boxes in the widget config).

mwbarker,
Thanks for the feedback. I updated the plugin/widget a little while back and added some new features:
* Added the ability to limit the number of returned events
* Events can now be linked to their Google Calendar entriesI also fixed an issue where the events were appearing out of order.
Regarding the styling, I know it’s a bit redundant but I wanted to a) have a good place where some default CSS could be displayed and b) provide an easy way for users to rapidly alter the event CSS until they felt comfortable enough to add it to their theme (not everybody knows the joys of working with Firebug).
Let me know if you have any issues with the update.
