參考“僅當(dāng)在 Woocommerce 中應(yīng)用優(yōu)惠券時(shí)才允許購(gòu)買(mǎi)特定產(chǎn)品”對(duì)我之前的一個(gè)問(wèn)題的回答代碼，優(yōu)惠券代碼在函數(shù)中硬編碼，需要與 Woocommerce 中現(xiàn)有的優(yōu)惠券代碼匹配。但我想從 Woocommerce 動(dòng)態(tài)選擇優(yōu)惠券。如何從woocommerce動(dòng)態(tài)獲取優(yōu)惠券？

以下代碼擴(kuò)展了我之前的答案，并將在 WooCommerce > 優(yōu)惠券部分添加一個(gè)復(fù)選框，使任何優(yōu)惠券代碼對(duì)于特定定義的項(xiàng)目都是“強(qiáng)制性的”：
因此，這樣您就不必在函數(shù)中定義任何優(yōu)惠券代碼。
整個(gè)代碼：
// Add a custom checkbox to Admin coupon settings pages
add_action( 'woocommerce_coupon_options', 'add_coupon_option_checkbox', 10 );
function add_coupon_option_checkbox() {
woocommerce_wp_checkbox( array(
'id' => 'items_mandatory',
'label' => __( 'Force specific items', 'woocommerce' ),
'description' => __( 'Make this coupon mandatory for specific items.', 'woocommerce' ),
'desc_tip' => false,
) );
}
// Save the custom checkbox value from Admin coupon settings pages
add_action( 'woocommerce_coupon_options_save', 'save_coupon_option_checkbox', 10, 2 );
function save_coupon_option_checkbox( $post_id, $coupon ) {
update_post_meta( $post_id, 'items_mandatory', isset( $_POST['items_mandatory'] ) ? 'yes' : 'no' );
}
add_action( 'woocommerce_check_cart_items', 'mandatory_coupon_for_specific_items' );
function mandatory_coupon_for_specific_items() {
$targeted_ids = array(37); // The targeted product ids (in this array)
$applied_coupons = WC()->cart->get_applied_coupons();
$coupon_applied = false;
if( sizeof($applied_coupons) > 0 ) {
// Loop through applied coupons
foreach( $applied_coupons as $coupon_code ) {
$coupon = new WC_Coupon( $coupon_code );
if( $coupon->get_meta('items_mandatory') === 'yes' ) {
$coupon_applied = true;
break;
}
}
}
// Loop through cart items
foreach(WC()->cart->get_cart() as $cart_item ) {
// Check cart item for defined product Ids and applied coupon
if( in_array( $cart_item['product_id'], $targeted_ids ) && ! $coupon_applied ) {
wc_clear_notices(); // Clear all other notices
// Avoid checkout displaying an error notice
wc_add_notice( sprintf( 'The product"%s" requires a coupon for checkout.', $cart_item['data']->get_name() ), 'error' );
break; // stop the loop
}
}
}

試試這個(gè)，更改被評(píng)論：
add_action( 'woocommerce_check_cart_items', 'mandatory_coupon_for_specific_items' );
function mandatory_coupon_for_specific_items() {
// The targeted product ids (in this array)
$targeted_ids = array(37);
// Get applied $coupon_names
$cart_applied_coupons = WC()->cart->get_applied_coupons()
// Set the variable $coupon_applied to false
$coupon_applied = false;
// Create an array to save all coupon names
$coupon_names = array();
// Get the available coupons
$args = array(
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'asc',
'post_type' => 'shop_coupon',
'post_status' => 'publish',
);
$all_coupons = get_posts( $args );
if( !empty($all_coupons) ){
// Loop through the available coupons
foreach ( $all_coupons as $coupon ) {
// Get the name for each coupon and add to the previously created array
$coupon_name = $coupon->post_title;
array_push( $coupon_names, $coupon_name );
}
// If one on the coupons is applied change the value of $coupon_applied to true
foreach($coupon_names as $coupon_code){
if( in_array( strtolower($coupon_code), $cart_applied_coupons) ){
$coupon_applied = true;
break;
}
}
}
// Loop through cart items
foreach(WC()->cart->get_cart() as $cart_item ) {
// Check cart item for defined product Ids and applied coupon
if( in_array( $cart_item['product_id'], $targeted_ids ) && ! $coupon_applied ) {
wc_clear_notices(); // Clear all other notices
// Avoid checkout displaying an error notice
wc_add_notice( sprintf( 'The product"%s" requires a coupon for checkout.', $cart_item['data']->get_name() ), 'error' );
break; // stop the loop
}
}
}
