EE, SafeCracker, Ajax and updating multiple channels / entries

FYI => The UX called for a clean Ajax based updated within an ExpressionEngine SafeCracker form. That was fairly straightforward (aside from a quirk in the EE docs.) What wasn’t so standard was having to update two (or more) EE channels / entries via a single form submit. And this is where the alchemist magic started to happen.

http://expressionengine.com/user_guide/modules/safecracker/index.html

In the comments at the bottom of the page JT Thompson runs down a few examples on using Javascript to manipulate key form fields / values. What I did was use jQuery’s ajaxSuccess method and then do the necessary manipulation. That is, I changed the channel_id and then did a second submit. The other key thing to know is that ExpressionEngine / SafeCracker will ignore any fields that don’t apply to a given channel / submit. In other words, you can have fields on a form for two or more channels and not pull and errors. If the fields don’t apply to a channel update they simply get ignored.

In summary it went like this…Set up the SafeCracker form with fields for two different channel. Do the first submit. If / when there’s an ajaxSuccess change the channel_id to the second channel. Submit again. Ideally, there’s a second success*. Done.

* I haven’t yet tried to figure out what to do if the first update is a success and the second is not.
