Register users without confirmation

Question

I'm looking to register users without requiring confirmation of their emails (and even better, no password when they register). Basically, I want them to subscribe their mails using wp registration process and then redirect to a page of my choice.

I know I can do it with CF7, or a newsletter plugin or whatever, but I actually need to use the default registration process because it connects to another plugin which uses it, and the UX flow is as follows:

user enter mails --> user gets redirected to thank you page with a ref code (provided by plugin). 

It's as simple as this, yet couldn't find the answer and I was searching for hours.

Any help really appreciated!

Answer 1

Well there is a function called wp_new_user_notification() which is pluggable you can alter it to stop user registration email:

if ( ! function_exists( 'wp_new_user_notification' ) ) {
    function wp_new_user_notification( $user_id, $plaintext_pass = '' ) {
        return false; // because we don't need to send email.
    }
}

You can register user with different plugins. For example, plugin User Registration https://wordpress.org/plugins/user-registration/ does not require any e-mail confirmation.

If you want to write a plugin by yourself there is a function wp_create_user() - https://developer.wordpress.org/reference/functions/wp_create_user/ - it will help you to create a user in DB with login,password and e-mail. You can add your rules for registration. Another function register_new_user() - https://developer.wordpress.org/reference/functions/register_new_user/ - will generate password in system.

Answer 3

As one other answer noted, you can alter the wp_new_user_notification() function since it is pluggable. But it also has a filter hook wp_send_new_user_notification_to_user in it to stop the notification email from going out at all So if you use the filter instead, you don't have to alter the function (in case it gets used by other processes). You can use WP's __return_false() function to simply return a false boolean to the filter and stop the confirmation email to the user from going out:

add_filter( 'wp_send_new_user_notification_to_user', '__return_false' );
