Validate Across Columns

[mudmin]

The validate class won't do that by itself, so basically you'll have to run a query like

Code:

$checkQ = $db->query("SELECT * FROM users WHERE

.... //fill in your conditions here

Code:

$checkC = $checkQ->count();

//get a count of the results

Code:

if($checkC < 1) {

//No results found, therefore it is unique)
//do something

Code:

}
