Stop saving after a check in before save

[alextouch]

Hi

I need to do this:
After I have compiled an edit form, I want to do a check into the database on another table to see if there is a correspondence between data. If yes, the program must save, otherwise it must display an alert and avoid saving.

So it's possible to stop nuBuilder from saving data after a check in Custom Code/Before Save, like "return false" in Javascript?

Thank you
Alex

Alex,

If you attach a message to a variable named $errorMessage in the Before Save event, this message will not continue to save but return its self as a warning.

If $errorMessage remains empty a record will be saved.

Thank you for your answer.
I did the job with ajax, so that I can check correspondence directly from javascript.
