Can someone assist me on the use of the is_unique function for form validation using codeigniter? Here is my code:
$this->form_validation->set_rules('email', 'email', 'trim|valid_email|is_unique[users.email]');
How do I set users.email?
is_unique was added in CI 2.1.0. If you are using lower versions, then i suggest you look at this link: is_unique Codeigniter
Hope it helps
You must have a users table in your database, containing an email field.
<input name="email" />
must corrispond with you users table
`email varchar(128) not null unique`
then your rules, no params passed if NOT A CALLBACK!!
rules=>'trim|required|max_length[128]|valid_email|is_unique'
