Canceling saving of an item via onBeforeSaveField function

mmm, we could do this:

1. If any onBeforeSaveField() call returns false then the declare the saving process as failed
2. Then the saving controller task, will call delete TASK for new items and restore version TASK for existing items

Yes. It is exactly the wished behavior

I have opened a enhancement issue in bug tracker for this.

Currently, you should onBeforeSaveItem Event and examine the posted data that i proposed above, and thus stopping item changes before they happen.

Regards

This is a an interesting feature, but it was more tricky than i first thought


I have added this feature in r1348,r1349

If any FLEXIcontent field returns false IN ITS function onBeforeSaveField(...) then the item will not be created or altered

NOTE:
1. you must return false !!! not zero
e.g return (boolean) $counted_data;

2. The posted data of the new item or the changed data of the existing item are not reloaded YET !!! sorry did not have time for this

Great news !!!

To me, it is the expected behavior ("wrong" data does not have to be reloaded)

Yes but you may have changed several fields before clicking save,

so it would make sense to load old form values just before clicking,

but this would be a little tricky to do for elements that have multiple values added via Javascript , nevertheless it is possible
