<p>我在https://development.pittsburghconcertsociety.org上銷售活動(dòng)門票并接受捐款。當(dāng)有人購(gòu)買門票時(shí)，他們必須同意COVID政策。但是當(dāng)有人只“購(gòu)買”捐款，即他們只將捐款產(chǎn)品放入購(gòu)物車時(shí)，他們不需要同意COVID政策。WooCommerce支持聊天機(jī)器人提供了以下代碼，但是它不起作用：</p> <pre class="brush:php;toolbar:false;">function hide_terms_for_specific_product( $woocommerce_checkout_fields ) { // Check if the specific product is the only item in the cart if ( WC()->cart ) { $cart_items = WC()->cart->get_cart(); $specific_product_found = false; foreach ( $cart_items as $cart_item ) { // Replace '123' with the ID of the specific product if ( $cart_item['product_id'] == 551 ) { $specific_product_found = true; break; } } // Hide terms and conditions for the specific product if ( $specific_product_found ) { unset( $woocommerce_checkout_fields['terms'] ); } } return $woocommerce_checkout_fields; } add_filter( 'woocommerce_checkout_fields', 'hide_terms_for_specific_product' );</pre> <p>捐款產(chǎn)品的ID是551）?？偨Y(jié)一下，如果購(gòu)物車中有門票和捐款產(chǎn)品，我確實(shí)希望有T&C復(fù)選框/要求，但如果購(gòu)物車中只有捐款產(chǎn)品，則不需要T&C。在這種情況下，僅僅隱藏T&C是不夠的，它還必須不是必填項(xiàng)。</p><p>此外，如果我們銷售商品，能夠添加多個(gè)產(chǎn)品ID將會(huì)很好。</p><p><br /></p>
