有些商品用郵局寄送比用宅配便宜，所以較大的商品希望可以限制客人只能用郵局郵寄。修改後的畫面如下：
其他無大面積商品時：
設定方式，目前是「純手工」，在商品的編輯畫面裡增加metadata:
shipping_post_only = 1
純手工去加入欄位太不人性化，增加 3個副程式，就可以在 WooCommerce 裡增加新的Tab.

我的 functions.php
function dynamically_show_shipping_rates( $rates ) {
$free = array();
$is_shipping_post_only = 0;
foreach (WC()->cart->get_cart() as $item_key => $item) {
if ($item['data']->needs_shipping()) {
$val = get_post_meta($item['product_id'], 'shipping_post_only', true);
if ($val==1) {
$is_shipping_post_only=1;
break;
}
}
}
if ($is_shipping_post_only==1) {
unset($rates['flat_rate:5']);
unset($rates['flat_rate:3']);
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'dynamically_show_shipping_rates', 100 );
有沒有方法可以讓每一訂單金額大於指定數目,只能選用指定付款方式,如over$500 只能銀行轉帳,under 500 ,可以paypal/銀行轉帳.
解法：
add_filter('woocommerce_available_payment_gateways', 'woocs_filter_gateways', 1);
function woocs_filter_gateways($gateway_list)
{
if (WC()->cart->subtotal > 1000)
{
unset($gateway_list['cod']);
}
return $gateway_list;
}
動態增加貨運方式的方法：
/**
* Developers can add additional flat rates based on this one via this action since @version 2.4.
*
* Previously there were (overly complex) options to add additional rates however this was not user.
* friendly and goes against what Flat Rate Shipping was originally intended for.
*
* This example shows how you can add an extra rate based on this flat rate via custom function:
*
* add_action( 'woocommerce_flat_rate_shipping_add_rate', 'add_another_custom_flat_rate', 10, 2 );
*
* function add_another_custom_flat_rate( $method, $rate ) {
* $new_rate = $rate;
* $new_rate['id'] .= ':' . 'custom_rate_name'; // Append a custom ID.
* $new_rate['label'] = 'Rushed Shipping'; // Rename to 'Rushed Shipping'.
* $new_rate['cost'] += 2; // Add $2 to the cost.
*
* // Add it to WC.
* $method->add_rate( $new_rate );
* }.
*/
作法二號：
/**
* Hide paid shipping rates when free shipping is available. Also remove the
* 'Free Shipping with Signature' option when the order total < 500.
*
* @param array $rates Array of rates found for the package.
* @return array
*/
function dynamically_show_shipping_rates( $rates ) {
$free = array();
$cart_subtotal = WC()->cart->subtotal;
// Only display the free option and pseudo-free option when free shipping is eligible
foreach ( $rates as $rate_id => $rate ) {
if ( 'free_shipping' === $rate->method_id || $rate_id === 'flat_rate:7' ) {
$free[ $rate_id ] = $rate;
}
}
// Always remove the pseudo-free rate from $rates; it will always be in $free array if
// if free shipping is enabled, and that will always be returned below when appropriate
unset($rates['flat_rate:7']);
return $cart_subtotal >= 500 ? $free : $rates;
}
add_filter( 'woocommerce_package_rates', 'dynamically_show_shipping_rates', 100 );
