WooCommerce 教程：状态选择 Checkout 页面后显示消息

我的一个 WooCommerce 定制客户端请求了这个很棒的功能。他们希望在选择状态时，在结帐页面上有条件地显示 DIV 。

代码段：显示条件内容 @ WooCommerce Checkout

/**

// 1. Create the text box and place it over the order review. Notice the display:none!

function add_checkout_notice() {

echo '<p class="checkout_notice" style="color:red;float:left;display:none">This text here will show when one of the chosen states is selected</p>';
}

add_action( 'woocommerce_review_order_before_cart_contents', 'add_checkout_notice', 10 );

// 2. Function to show/hide the text box by US State

add_action( 'woocommerce_review_order_before_cart_contents', 'show_checkout_notice', 12 );

function show_checkout_notice() {

global $woocommerce;

$msg_states = array( 'AL','FL','GA','SC','NC','MD','DC','PA','NJ','NY','CT','RI','MA','VT','NH','ME','VA' );

if( in_array( WC()->customer->shipping_state, $msg_states ) ) {

echo '<style>.checkout_notice{display:block !important}</style>';

} else {

echo '<style>.checkout_notice{display:none !important}</style>';

}

}
