Want to welcome your users nicely? you can send them a message. Add following code in your theme’s (child theme’s if any) functions.php
add_action( 'user_register', 'fep_cus_user_register_send_messaage', 10, 1 );
function fep_cus_user_register_send_messaage( $user_id ){
if ( $user_id < 1 )
return;
if ( ! function_exists( 'fep_send_message' ) )
return;
// Prepare message data
$message = array(
'message_title' => 'Welcome ' . fep_get_userdata( $user_id, 'display_name', 'id' ), //change with message title
'message_content' => 'CONTENT', //change with message content
'message_to_id' => $user_id
);
$override = array(
'mgs_author' => 1, //change with message sender id
);
// Send message
fep_send_message( $message, $override );
}
