如果购物车中的产品类别,WooCommerce 条件自定义字段
WooCommerce Conditional Custom Fields if Product Category in Cart
好吧,我被难住了。我已经搜索并阅读了几个 post,包括相关的 post Checking products in cart based on category name woocommerce? from where I derived much of this code, and Woocommerce - Add filter to display (or hide) custom checkout field if product ID == #,它特定于产品 ID,而不是类别 ID。
当且仅当目标类别 ID(在本例中为 237)在购物车中时,我想显示 sdc_custom_checkout_field。
我尝试注释掉 sdc_custom_checkout_field 函数并使用如下所示的简单测试,但一直得到 "Nope!",因此我认为查询不正确。
add_action( 'woocommerce_before_order_notes', 'sdc_custom_checkout_field' );
function sdc_custom_checkout_field( $checkout ) {
//Check if Product in Cart
//$product_in_cart = check_product_in_cart();
//Product is in cart so show additional fields
if ( $product_in_cart === true ) {
echo '<div id="my_custom_checkout_field"><h3>' . __( 'Duplicate Card Information' . '</h3><br>');
woocommerce_form_field( 'dupecard_location', array(
'type' => 'text',
'class' => array( 'dupecard-location form-row-wide' ),
'label' => __( 'Course Location' ),
), $checkout->get_value( 'dupecard_location' ) );
woocommerce_form_field( 'dupecard_instructor', array(
'type' => 'text',
'class' => array( 'dupecard-instructor form-row-wide' ),
'label' => __( 'Instructor Name' ),
), $checkout->get_value( 'dupecard_instructor' ) );
woocommerce_form_field( 'dupecard_requestor_name', array(
'type' => 'text',
'class' => array( 'dupecard-requestor-name form-row-wide' ),
'label' => __( 'Requestor Name' ),
), $checkout->get_value( 'dupecard_requestor_name' ) );
woocommerce_form_field( 'dupecard_requestor_email', array(
'type' => 'text',
'class' => array( 'dupecard-requestor-email form-row-wide' ),
'label' => __( 'Requestor Email' ),
), $checkout->get_value( 'dupecard_requestor_email' ) );
woocommerce_form_field( 'dupecard_requestor_phone', array(
'type' => 'text',
'class' => array( 'dupecard-requestor-phone form-row-wide' ),
'label' => __( 'Requestor Phone' ),
), $checkout->get_value( 'dupecard_requestor_phone' ) );
echo '</div>';
}
}
function check_product_in_cart() {
//Check to see if user has product in cart
global $woocommerce;
//assign default negative value
$product_in_cart = false;
// start cart items fetch loop
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
$terms = get_the_terms( $_product->id, 'product_cat' );
// second level loop search, in case some items have several categories
$cat_ids = array();
foreach ($terms as $term) {
$cat_ids[] = $term->term_id;
}
if(in_array(237, (array)$cat_ids)) {
//category is in cart!
$product_in_cart = true;
}
}
return $product_in_cart;
}
这是测试片段:
if ($item_in_cart === true) {echo 'YES';}
else {echo 'Nope!';}
我也换了
$item_in_cart
和
$product_in_cart
但没有区别。
