根据 WooCommerce 结账中的分类术语限制支付网关

Question

在我的 WooCommerce 商店中，只有当产品具有类别 ID 为“266”的特定产品类别时，我才想限制和显示支付网关（支票）。现在我有了这个片段，但它的作用正好相反——它禁用了特定产品类别结账时的网关：

add_filter( 'woocommerce_available_payment_gateways', 'bbloomer_unset_gateway_by_category' );

  

function bbloomer_unset_gateway_by_category( $available_gateways ) {

    if ( is_admin() ) return $available_gateways;

    if ( ! is_checkout() ) return $available_gateways;

    $unset = false;

    $category_ids = array( 8, 37 );

    foreach ( WC()->cart->get_cart_contents() as $key => $values ) {

        $terms = get_the_terms( $values['product_id'], 'product_cat' );    

        foreach ( $terms as $term ) {        

            if ( in_array( $term->term_id, $category_ids ) ) {

                $unset = true;

                break;

            }

        }

    }

    if ( $unset == true ) unset( $available_gateways['cheque'] );

    return $available_gateways;

}

使用has_term()WordPress 条件函数将简化代码使其更有效，这样：add_filter( 'woocommerce_available_payment_gateways', 'filter_available_payment_gateways' );function filter_available_payment_gateways( $available_gateways ) {    // Only on checkout page    if ( is_checkout() && ! is_wc_endpoint_url() ) {        // Here define your product categories        $product_categories = array( 't-shirts', 'posters' ); // Can be term names, term slugs or term ids        $taxonomy = 'product_cat'; // For WooCommerce product category terms (or 'product_tag' for WooCommerce product tag terms)        $payment_method     = 'cheque'; // Here define your payment method id to be removed        $hide_payment       = false;        // Loop through cart items        foreach ( WC()->cart->get_cart_contents() as $item ) {            if ( ! has_term( $product_categories, $taxonomy, $item['product_id'] ) ) {                $hide_payment = true;            }        }                if ( $hide_payment ) {            unset( $available_gateways[$payment_method] );        }    }    return $available_gateways;}代码位于活动子主题（或活动主题）的 functions.php 文件中。测试和工作。改为处理产品标签只需将代码中的分类法替换'product_cat'为'product_tag'.也针对父产品类别如果您还需要定位父产品类别，则必须改用它：// Custom conditional function that handle parent product categories toofunction 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;}add_filter( 'woocommerce_available_payment_gateways', 'filter_available_payment_gateways' );function filter_available_payment_gateways( $available_gateways ) {    // Only on checkout page    if ( is_checkout() && ! is_wc_endpoint_url() ) {        // Here define your product categories        $product_categories = array( 't-shirts', 'posters' ); // Can be term names, term slugs or term ids        $taxonomy = 'product_cat'; // For WooCommerce product category terms (or 'product_tag' for WooCommerce product tag terms)        $payment_method     = 'cheque'; // Here define your payment method id to be removed        $hide_payment       = false;        // Loop through cart items        foreach ( WC()->cart->get_cart_contents() as $item ) {            if ( ! has_product_categories( $product_categories, $item['product_id'] ) ) {                $hide_payment = true;            }        }                if ( $hide_payment ) {            unset( $available_gateways[$payment_method] );        }    }    return $available_gateways;}代码位于活动子主题（或活动主题）的 functions.php 文件中。测试和工作。

你能在你的代码中改变你的条件吗if ( $unset == true ){     $index = 0;    foreach($available_gateways as $single){        if($single != "cheque"){            unset($available_gateways[$index]);        }           $index++;    } }
