Added code formatting for print_r
Feb 15, 2015 at 17:00 comment added alex @birgire wow never looked into the add_action function, that indeed is suprising. Thanks for the class_exists suggestion!
Feb 15, 2015 at 16:34 comment added birgire ps: it's rather surprising at first to see that the add_action function definition is actually only a single line of code, namely a call to the add_filter() function ;-)

Feb 15, 2015 at 16:17 comment added birgire You should consider using the hook mentioned by @PieterGoosen and additionally you might want to add a if( class_exists( 'Attachments' ) ) check into your code so it won't break if the corresponding external plugin is removed.
