I would like to create validate unique more columns

example

id firstname lastname

1 foo foo

2 foo test

3 test test

but

insert foo , foo result validate duplication

(sorry I am not good englist

2

use unique validator for that

read here more http://www.yiiframework.com/doc/guide/1.1/en/form.model#declaring-validation-rules also there is in wiki article about it

3

try adding below to model ruels


array('firstname','unique','message'=>'Firstname {value} already in use!'),
4

this won’t work if not used from CActiveRecord…

for CFormModel it has additional parameters…

best look in wiki, there is very good article with all parameters available for every built in validation
