WooCommerce：檢查優惠券是否有效

Question

我試圖檢查優惠券是否仍然有效（尚未達到其使用限制）並在此條件下顯示內容。

原因是我希望能夠向特定訪客發放優惠券代碼，但顯然不想分發已經達到其使用限制的優惠券。

我想用PHP來實現這一點，想象中的代碼是這樣的：

<?php if (coupon('mycouponcode') isvalid) { 
    echo "Coupon Valid" 
} else { 
    echo "Coupon Usage Limit Reached" 
} ?> 

:)

$code = 'test123'; 

$coupon = new WC_Coupon($code); 
$coupon_post = get_post($coupon->id); 
$coupon_data = array(
    'id' => $coupon->id, 
    'code' => $coupon->code, 
    'type' => $coupon->type, 
    'created_at' => $coupon_post->post_date_gmt, 
    'updated_at' => $coupon_post->post_modified_gmt, 
    'amount' => wc_format_decimal($coupon->coupon_amount, 2), 
    'individual_use' => ('yes' === $coupon->individual_use), 
    'product_ids' => array_map('absint', (array) $coupon->product_ids), 
    'exclude_product_ids' => array_map('absint', (array) $coupon->exclude_product_ids), 
    'usage_limit' => (!empty($coupon->usage_limit)) ? $coupon->usage_limit : null, 
    'usage_count' => (int) $coupon->usage_count, 
    'expiry_date' => (!empty($coupon->expiry_date)) ? date('Y-m-d', $coupon->expiry_date) : null, 
    'enable_free_shipping' => $coupon->enable_free_shipping(), 
    'product_category_ids' => array_map('absint', (array) $coupon->product_categories), 
    'exclude_product_category_ids' => array_map('absint', (array) $coupon->exclude_product_categories), 
    'exclude_sale_items' => $coupon->exclude_sale_items(), 
    'minimum_amount' => wc_format_decimal($coupon->minimum_amount, 2), 
    'maximum_amount' => wc_format_decimal($coupon->maximum_amount, 2), 
    'customer_emails' => $coupon->customer_email, 
    'description' => $coupon_post->post_excerpt, 
); 

$usage_left = $coupon_data['usage_limit'] - $coupon_data['usage_count']; 

if ($usage_left > 0) { 
    echo 'Coupon Valid'; 
} 
else { 
    echo 'Coupon Usage Limit Reached'; 
} 

的代碼測試完全在這裏的任何幫助將是巨大的功能。
