In this post I will show an example of how apply the unique validation rule in CakePHP 1.2. It’s very important to do in some cases, like saving users. You must make sure that the username is unique in your system. Lets see how it works:
var $validate = array(
'username' => array(
'rule' => array('isUnique'),
'message' => 'Username already in use.'
)
);
I wrote a custom function to validate it, but thanks to Dia now I know the built-in validation rule.

CakePHP 1.2 has a built-in unique validation rule :
var $validate = array( ‘myField’ => array( ‘rule’ => ‘isUnique’, ‘message’ => ‘data already exists’ ));

Thanks for the information, I didn’t see this rule. But I already fixed the post to use it. It’s better then custom functions.

But what if you need unique validation for multiple fields? For example, a comment rating system in which a user is allowed only one vote, so a unique key is set for user_id and comment_id.

Thanks a lot! It’s very useful for version 1.2

This is a good article, I discovered your blog page checking bing for a related topic and arrived to this. I couldnt get to much additional details on this article, so it was wonderful to locate this one. I will likely end up being returning to look at some other posts that you have another time.
