I add validator to email element:
$usr_email->addValidator('Db_NoRecordExists', true, array('users', 'usr_email'));
And now have error message: A record matching 'admin@example' was found
I want change this error, but I want that will display inserted email
A email 'admin@example' already exist in database I try , but email not disply ant html tags
addErrorMessage("**This email **strong text** address already exist.**");
