我是新的WordPress插件开发人员。我正在开发一个插件，其中我创建了一个自定义购物车页面，比如woo commerce购物车。我还添加了wc add notice，当商品从购物车页面中删除时，它会在此页面上显示一个通知，以及当我刷新店铺/拱形页面上的店铺显示时。我不知道怎么处理。对不起，英语不好，提前谢谢你。
public function WhatsApp_cart_page_setting1() {
if ( empty( WC()->session->get( \'WhatsApp_cart\' ) ) ) {
return;
}
if ( isset( $_GET[\'index_to_remove\'] ) ) {
$index = sanitize_text_field( wp_unslash( $_GET[\'index_to_remove\'] ) );
$cart_session = WC()->session->get( \'WhatsApp_cart\' );
unset( $cart_session[ $index ] );
WC()->session->set( \'WhatsApp_cart\', $cart_session );
$page = get_page_by_path( \'whatsapp-cart\' );
global $post;
$whatsapp_slug = $post->post_name;
if ( $whatsapp_slug === \'whatsapp-cart\' ) {
wc_add_notice( \'Item removed from whatsapp cart successfully\', \'success\' );
}
}
?>

我下面解决这个问题的是代码。
add_action( \'woocommerce_init\', array( $this, \'afwo_add_notices\' ) );
public function afwo_add_notices() {
if ( isset( $_POST[\'whatsapp_cart_nonce_field\'] ) && wp_verify_nonce(
sanitize_text_field( wp_unslash( $_POST[\'whatsapp_cart_nonce_field\'] ) ),
\'whatsapp_cart_field\' ) ) {
echo \'\';
}
if ( empty( WC()->session->get( \'WhatsApp_cart\' ) ) ) {
return;
}
if ( isset( $_GET[\'index_to_remove\'] ) ) {
$index = sanitize_text_field( wp_unslash( $_GET[\'index_to_remove\']
) );
$cart_session = WC()->session->get( \'WhatsApp_cart\' );
if ( isset( $cart_session[ $index ] ) ) {
unset( $cart_session[ $index ] );
WC()->session->set( \'WhatsApp_cart\', $cart_session );
wc_add_notice( \'Item removed from whatsapp cart successfully\',
\'success\' );
}
}
}
