[英]Add custom checkout field based on product category in Woocommerce
我需要根據產品類別添加自定義結帳字段。 我發現這段代碼適用於產品,但是從特定類別的每個新產品中添加 Id 非常耗時。
function is_in_cart() {
// Add your special product IDs here
$ids = array( 12468, 9687, 9693);
foreach( WC()->cart->get_cart() as $cart_item ){
$product_id = version_compare( WC_VERSION, '3.0', '<' ) ? $cart_item['data']->id : $cart_item['data']->get_id();
if( in_array( $cart_item['data']->get_id(), $ids ) )
return true;
}
return false;
}
/**
* Add the field to the checkout
*/
add_action( 'woocommerce_before_order_notes', 'custom_checkout_field', 20 );
function custom_checkout_field( $checkout ) {
if( ! is_in_cart() ){
woocommerce_form_field( 'special_field', array(
'type' => 'textarea',
'class' => array('form-row-wide'),
'label' => pll__('Special text'),
'required' => false,
'label_class' => array('specialfieldclass'),
'clear' => false,
), $checkout->get_value( 'special_field' ));
}
}
如何修改此代碼以使用產品類別?
嘗試以下方法來處理產品類別(也處理父術語) :
// Custom conditional function that handle parent product categories too
function has_product_categories( $categories, $product_id = 0 ) {
$parent_term_ids = $categories_ids = array(); // Initializing
$taxonomy = 'product_cat';
$product_id = $product_id == 0 ? get_the_id() : $product_id;
if( is_string( $categories ) ) {
$categories = (array) $categories; // Convert string to array
}
// Convert categories term names and slugs to categories term ids
foreach ( $categories as $category ){
$result = (array) term_exists( $category, $taxonomy );
if ( ! empty( $result ) ) {
$categories_ids[] = reset($result);
}
}
// Loop through the current product category terms to get only parent main category term
foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
if( $term->parent > 0 ){
$parent_term_ids[] = $term->parent; // Set the parent product category
$parent_term_ids[] = $term->term_id; // (and the child)
} else {
$parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
}
}
return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}
// Custom conditional function that check for product categories
function is_in_cart() {
// HERE your product categories
$categories = array( 'clothing' );
foreach( WC()->cart->get_cart() as $cart_item ){
if( has_product_categories( $cart_item['product_id'], $categories ) )
return true;
}
return false;
}
// Add a checkout field before order notes
add_action( 'woocommerce_before_order_notes', 'custom_checkout_field', 20 );
function custom_checkout_field( $checkout ) {
if( ! is_in_cart() ){
woocommerce_form_field( 'special_field', array(
'type' => 'textarea',
'class' => array('form-row-wide'),
'label' => pll__('Special text'),
'required' => false,
'label_class' => array('specialfieldclass'),
'clear' => false,
), $checkout->get_value( 'special_field' ));
}
}
代碼位於活動子主題(或活動主題)的 functions.php 文件中。 它應該有效。
