Hello there,

hope you are doing well 🙂

To set manual payments, you only have to follow these simple steps:
YITH -> Affiliates -> Commissions -> Bulk actions -> Create a payment manually, and the commission payment will be processed.

If you want to add a bank details field in the registration form, please add the following code to the functions.php file of your active theme:

if ( defined( 'YITH_WCAF' ) ) {
	if ( ! function_exists( 'yith_wcaf_add_custom_fields' ) ) {
		function yith_wcaf_add_custom_fields() {
			$fields = "<p class='form-row form-row-wide'>
                           <label for='bank_details'>Bank details<span class='required'>*</span></label>
                           <input type='text' class='input-text' name='bank_details' id='bank_details' value='' />
                       </p>
                       ";

			echo $fields;
		}

		add_action( 'yith_wcaf_register_form', 'yith_wcaf_add_custom_fields' );
		add_action( 'yith_wcaf_settings_form_after_payment_email', 'yith_wcaf_add_custom_fields' );
	}

	if ( ! function_exists( 'yith_wcaf_register_custom_field' ) ) {
		function yith_wcaf_register_custom_field( $id ) {
			$affiliate = YITH_WCAF_Affiliate_Handler()::get_instance()->get_affiliate_by_id( $id );

			if ( isset( $_REQUEST['bank_details'] ) ) {
				update_user_meta( $affiliate['user_id'], 'bank_details', sanitize_text_field( $_REQUEST['bank_details'] ) );
			}
		}
		add_action( 'yith_wcaf_new_affiliate', 'yith_wcaf_register_custom_field' );
	}

	if ( ! function_exists( 'yith_wcaf_register_custom_field_settings' ) ) {
		function yith_wcaf_register_custom_field_settings( $change, $id ) {
			if ( isset( $_REQUEST['bank_details'] ) ) {
				update_user_meta( $id, 'bank_details', sanitize_text_field( $_REQUEST['bank_details'] ) );
			}
		}
		add_action( 'yith_wcaf_save_affiliate_settings', 'yith_wcaf_register_custom_field_settings', 10, 2 );
	}

	if ( ! function_exists( 'yith_wcaf_show_custom_field' ) ) {
		function yith_wcaf_show_custom_field( $user ) {
			?>

		add_action( 'show_user_profile', 'yith_wcaf_show_custom_field', 21, 1 );
		add_action( 'edit_user_profile', 'yith_wcaf_show_custom_field', 21, 1 );
	}

	if ( ! function_exists( 'yith_wcaf_update_custom_field' ) ) {
		function yith_wcaf_update_custom_field( $user_id ) {
			if ( ! current_user_can( 'edit_user', $user_id ) ) {
				return;
			}

			if ( isset( $_POST['bank_details'] ) ) {
				update_user_meta( $user_id, 'bank_details', sanitize_text_field( $_POST['bank_details'] ) );
