Question

在我的wooocommerce商店中，仅当产品具有类别ID为“ 266”的特定产品类别时，我才想限制并显示付款网关（支票）。现在，我有了这个代码段，但是却相反：它在结帐时针对特定产品类别禁用了网关：

使用has_term() WordPress条件函数可以简化代码，使其更有效，方法如下：

add_filter( 'woocommerce_available_payment_gateways', 'filter_available_payment_gateways' );
function filter_available_payment_gateways( $available_gateways ) {
    // Only on checkout page
    if ( is_checkout() ) {
        // Here define your product categories
        $product_categories = array( 't-shirts', 'posters' ); // Can be term names, term slugs or term ids

        $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, 'product_cat', $item['product_id'] ) ) {
                $hide_payment = true;
            }
        }

        if ( $hide_payment ) {
            unset( $available_gateways[$payment_method] );
        }
    }
    return $available_gateways;
}

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试，可以正常工作。

如果您还需要定位父产品类别，那么您将不得不使用它：

// Custom conditional function that handle parent product categories too
function has_product_categories( $categories, $product_id = 0 ) {
     // Initializing
    $parent_term_ids = $categories_ids = array();
    $taxonomy        = 'product_cat';

    if( is_string( $categories ) ) {
        $categories = (array) $categories;
    }

    $product_id = $product_id > 0 ? get_the_id() : $product_id;

    // Convert categories term names and slugs to categories term ids
    foreach ( $categories as $category ){
        if( is_numeric( $category ) ) {
            $categories_ids[] = (int) $category;
        } elseif ( term_exists( sanitize_title( $category ), $taxonomy ) ) {
            $categories_ids[] = get_term_by( 'slug', sanitize_title( $category ), $taxonomy )->term_id;
        }
    }

    // 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() ) {
        // Here define your product categories
        $product_categories = array( 't-shirts', 'posters' ); // Can be term names, term slugs or term ids

        $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;
}

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试，可以正常工作。

您能否在代码中更改条件

if ( $unset == true ){
     $index = 0;
    foreach($available_gateways as $single){
        if($single != "cheque"){
            unset($available_gateways[$index]);
        }   
        $index++;
    }
 }
