Fields validation on submission

Hi,
is there a way in Flexi to validate (or not) fields after a form submission ?
I searched on the site and forum, but have not seen anything.
Thanks for help. Regards

... you can only use requier option for field ...
no validation type email or number ...

Yes you can validate the fields after form is submitted:

inside plugin function (of your FLEXIcontent field):

onBeforeSaveField(...){
...
}

make the checks that you need, if they fail, you can return false, (Not zero, return false)

and this will cancel new item creation or existing item save, and the user form will be reloaded with old item data

I need to document this ...
