使用php codeigniter创建一个电子邮件检查器

Question

Please help me in creating a form which allows a user to submit valid email.

When someone try to enter an email id, it should be validated before submitted to data base. Some of the examples for junk email ids are [e-mail], [e-mail] etc.

If an user try to enter an email id as mentioned in the above example, it should be verified whether it is a valid email id or not and also check if the user with the email id already exists?

Kindly help me building a code in php codeigniter.

There is a build-in functionality in CI handling this for you. It is in the form validation library.

See: https://ellislab.com/codeigniter/user-guide/libraries/form_validation.html

$this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');

note the valid_email rule which is already provided for you.

Hope it helps.
