Validation Rules: Valid email, but allow null? - sevmusic - 05-19-2025
In my app I have 2 email address fields.
The first field is required because it's the main account.
The second field is optional.
Here are my rules currently.
PHP Code:
public $profile = [
'login_email' => ['label' => 'Login Email', 'rules' => 'required|valid_email'],
'login_email_2' => ['label' => '2nd Login Email', 'rules' => 'valid_email']
];
But when I leave the login_email_2 field blank it complains that it's not a valid email.
How can I ignore the valid email rule if the field is blank?
I think I solved my own problem with permit_empty
Is there a listing of all the codeigniter validation rules?
I didn't see them singled out in the docs.

Rules for General Use.

You can not have an email that is empty using that rule, you could check it an see if it has a value
in your code then set it to permit_empty and remove the valid_email one check it in your code.
