Change the select element on checkout

Hi,

To do something like that it would require removing the filter that creates the select input calling this function: https://github.com/hallme/woo-address-book/blob/dec8ed350a109cd20ec9153ac49208def74d655d/includes/class-wc-address-book.php#L613-L652

Using this:
remove_filter( 'woocommerce_checkout_fields', array( WC_Address_Book::get_instance(), 'checkout_address_select_field' ), 9999, 1 );

And then you would need to write your own custom function to do what you want instead of the checkout_address_select_field function.

The remove filter is fine, but to target a custom function in your functions.php you would run the add_filter like:

add_filter( 'woocommerce_checkout_fields', 'checkout_address_custom_function', 9999, 1 );

since it is not part of the WC_Address_Book class.

What is the actual error? My guess would be because the function uses a lot of $this so you would have to change those. This should work.

add_filter( 'woocommerce_checkout_fields', 'checkout_address_custom_function', 9999, 1 );

function checkout_address_custom_function( $fields ) {
	if ( is_user_logged_in() ) {
		$wc_address_book_plugin = WC_Address_Book::get_instance();
		foreach ( $fields as $type => $address_fields ) {
			if ( ( 'billing' === $type && $wc_address_book_plugin->get_wcab_option( 'billing_enable' ) === true ) || ( 'shipping' === $type && $wc->get_wcab_option( 'shipping_enable' ) === true ) ) {
				$address_book = $wc_address_book_plugin->get_address_book( null, $type );

				$address_selector                            = array();
				$address_selector[ $type . '_address_book' ] = array(
					'type'     => 'select',
					'class'    => array( 'form-row-wide', 'address_book' ),
					'label'    => __( 'Address Book', 'woo-address-book' ),
					'order'    => -1,
					'priority' => -1,
				);

				if ( ! empty( $address_book ) && false !== $address_book ) {
					$default_to_new_address = $wc_address_book_plugin->get_wcab_option( $type . '_default_to_new_address', 'no' );

					foreach ( $address_book as $name => $address ) {
						if ( ! empty( $address[ $name . '_address_1' ] ) ) {
							$address_selector[ $type . '_address_book' ]['options'][ $name ] = $wc_address_book_plugin->address_select_label( $address, $name );
						}
					}

					$address_selector[ $type . '_address_book' ]['options']['add_new'] = __( 'Add New Address', 'woo-address-book' );

					if ( true === $default_to_new_address ) {
						$address_selector[ $type . '_address_book' ]['default'] = 'add_new';
					} else {
						$address_selector[ $type . '_address_book' ]['default'] = $type;
					}

					$fields[ $type ] = $address_selector + $fields[ $type ];
				}
			}
		}
	}

	return $fields;
}

I just tested it out. That part was fine, just a typo in one of the variables when I was using it.

Here is the updated version of everything.

remove_filter( 'woocommerce_checkout_fields', array( WC_Address_Book::get_instance(), 'checkout_address_select_field' ), 9999, 1 );
add_filter( 'woocommerce_checkout_fields', 'checkout_address_custom_function', 9999, 1 );

function checkout_address_custom_function( $fields ) {
	if ( is_user_logged_in() ) {
		$wc_address_book_plugin = WC_Address_Book::get_instance();
		foreach ( $fields as $type => $address_fields ) {
			if ( ( 'billing' === $type && $wc_address_book_plugin->get_wcab_option( 'billing_enable' ) === true ) || ( 'shipping' === $type && $wc_address_book_plugin->get_wcab_option( 'shipping_enable' ) === true ) ) {
				$address_book = $wc_address_book_plugin->get_address_book( null, $type );

				$address_selector                            = array();
				$address_selector[ $type . '_address_book' ] = array(
					'type'     => 'select',
					'class'    => array( 'form-row-wide', 'address_book' ),
					'label'    => __( 'Address Book', 'woo-address-book' ),
					'order'    => -1,
					'priority' => -1,
				);

				if ( ! empty( $address_book ) && false !== $address_book ) {
					$default_to_new_address = $wc_address_book_plugin->get_wcab_option( $type . '_default_to_new_address', 'no' );

					foreach ( $address_book as $name => $address ) {
						if ( ! empty( $address[ $name . '_address_1' ] ) ) {
							$address_selector[ $type . '_address_book' ]['options'][ $name ] = $wc_address_book_plugin->address_select_label( $address, $name );
						}
					}

					$address_selector[ $type . '_address_book' ]['options']['add_new'] = __( 'Add New Address', 'woo-address-book' );

					if ( true === $default_to_new_address ) {
						$address_selector[ $type . '_address_book' ]['default'] = 'add_new';
					} else {
						$address_selector[ $type . '_address_book' ]['default'] = $type;
					}

					$fields[ $type ] = $address_selector + $fields[ $type ];
				}
			}
		}
	}

	return $fields;
