empty() and null are very different. empty() will be true for a blank string, zero, or an empty array. In this particular case you have a HABTM relationship, and when saving a HABTM all existing connections are destroyed, and replaced with those passed.
So, if $this->data['Tag']['Tag'] is empty, it may be an empty array, and would delete all the HABTM joins. Replacing this with null will mean the existing joins are not affected. But the other parts - I'm not sure either. There must be some similar issue with the Tag being set to an empty, but not null value. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Cake PHP" group.
