You’ll need to be more specific. If you mean which hook fires when the registration page loads, then the answer is there are many. See here and look for the one you need.
I am not sure. I bought a plugin from codecanyon and am trying to alter it to work with buddypress. I think this is the code I will have to alter
public function __construct() {
$this -> admin = WP_Atr_Admin :: get_instance();
# registration hooks:
add_action( 'login_enqueue_scripts', array( $this, 'initialize_registration' ) );
add_action( 'register_form', array( $this, 'add_checkboxes_to_registration' ) );
add_filter( 'registration_errors', array( $this, 'validate_registration' ), 10, 3 );
# mu
add_action( 'signup_header', array( $this, 'initialize_registration' ) );
add_filter( 'wpmu_validate_user_signup', array( $this, 'mu_validate_registration' ), 10, 3 );
add_action( 'signup_extra_fields', array( $this, 'mu_add_checkboxes_to_registration' ) );
# add button
add_filter( 'the_content', array( $this, 'add_button_to_pages' ) );
$this -> register_page_status();
if( is_multisite() ) {
add_filter( 'all_plugins', array( $this, 'hide_plugin_in_mu_sites' ) );
}
}
I would figure I would prefix bp_ to some of the code here
# registration hooks:
add_action( ‘bp_login_enqueue_scripts’, array( $this, ‘initialize_registration’ ) );
add_action( ‘bp_register_form’, array( $this, ‘add_checkboxes_to_registration’ ) );
add_filter( ‘bp_registration_errors’, array( $this, ‘validate_registration’ ), 10, 3 );
but it like there is more to it than that according to your link.
