Need help implementing a logic hook

[bstonehill]

I need to execute some php code when a relationship field is changed. I found a list of available logic hooks and based on that it appears that what I may have to do is execute my code on every record save using the after_save hook and then have my php code determine if my criteria is met (relationship field changed). I have two questions, first am I correct in my assumption or is there a way to only fire the logic hook on that particular field, and will the after_save hook fire with mass update?

Also any tips/hints/article links on getting started with logic hooks would be greatly appreciated since this will be my first attempt at using them.

Thanks

If you have an after_save logic hook it will be kicked off after save. It will not fire only-if one field is changed. But in your php code you can have an action only happen if.

To check whether you have a change to the field you may need two logic hooks -- one to get the relationship before the save and one to check if it is different after the save.
