Already exist

I'm working on my project http://accoglienza.eservers.it/join.html

When I am creating a new entry I have to check if name and surname already exist, how I can do it?

Hi,

With a single field you would be able to use the unique validator that is built into Editor. However, with it being the combination of two fields, you would need to write a custom validation method.

I don't know how to validate both columns with an AND operator

example: if persone.nome AND persone.cognome is unique

Field::inst( 'persone.nome' ),
Field::inst( 'persone.cognome' ),
    ->validator( 'Validate::unique', array('required'=>true,'message'=>'duplicated')),

You need to write a custom validator, detailed which you can find at the link I gave above. As I say, there isn't a built in validator that will check the uniqueness of two values combined.

I really don't know how to do it, I need an example to understand.

Can you do it for me, I can pay your service.
If I can deal directly with you write me an email to info@eservers.it

Certainly - I'd be happy to write an example of this under the DataTables support options. The Quick Support 60 option would cover it.
