php - 获取 WooCommerce 中的最小变动价格

Question

我是一个初学者，试图学习 Wordpress 并拥有价格可变的产品:

鳕鱼 250 卢比

在线 200 卢比

我想在我的主题中使用最低价格 functions.php .

我将如何获取或获得最小值？

我想在下面的代码中使用:

function filter_gateways($gateways){

    $payment_NAME = 'cod'; // 
    $min_variation_price = ''; <--------------- minimum variation price

    global $woocommerce;

    foreach ($woocommerce->cart->cart_contents as $key => $values ) {
        // Get the terms, i.e. category list using the ID of the product
        $terms = get_the_terms( $values['product_id'], 'product_cat' );
        // Because a product can have multiple categories, we need to iterate through the list of the products category for a match
        foreach ($terms as $term) {
            // 20 is the ID of the category for which we want to remove the payment gateway
            if($term->term_id == $min_variation_price){
                unset($gateways[$payment_NAME]);
                // If you want to remove another payment gateway, add it here i.e. unset($gateways['cod']);
                break;
            }
            break;
        }
    }
    return $gateways;
}

从 中获取 WooCommerce 中的最小变化事件价格WC_Product_Variable 目的:

$variation_min_price = $product->get_variation_price();

It seems that you are trying here to unset 'cod' payment gateway when a cart item min variation price is matching with his product category ID.

使用 WordPress 条件函数 has_term() 将真正简化您的代码(它接受任何分类法的术语 Id、术语 slug 或术语名称(如这里的产品类别的“product_cat”)。
我想你的函数是在 中 Hook 的woocommerce_available_payment_gateways 过滤钩…
我对您的代码进行了一些更改，因为它有点过时并且有一些错误:

add_filter('woocommerce_available_payment_gateways', 'conditional_payment_gateways', 10, 1);
function conditional_payment_gateways( $available_gateways ) {
    // Not in backend (admin)
    if( is_admin() ) 
        return $available_gateways;

    foreach (WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        // Get the WC_Product object
        $product = wc_get_product($cart_item['product_id']);
        // Only for variable products
        if($product->is_type('variable')){
            // Get the Variation "min" price
            $variation_min_price = $product->get_variation_price();
            // If the product category match with the variation 'min" price
            if( has_term( $variation_min_price, 'product_cat', $cart_item['product_id'] ) ){
                // Cash on delivery (cod) payment gateway
                unset($available_gateways['cod']); // unset 'cod'
                break; // stop the loop
            }
        }
    }
    return $available_gateways;
}

代码位于您的事件子主题(或主题)的 functions.php 文件中或任何插件文件中。
这应该有效(但我无法真正测试它，因为它对产品类别 ID 和最小变化价格非常具体)......

可变产品类型的所有相关价格方法:

// All prices: multidimensional array with all variation prices (including active prices, regular prices and sale prices). 
$prices = $product->get_variation_prices();
$prices_for_display = $product->get_variation_prices( true ); // For display

// The min or max active price.
$min_price = $product->get_variation_price(); // Min active price
$min_price_for_display = $product->get_variation_price('min', true); // Min active price for display
$max_price = $product->get_variation_price('max'); // Max active price
$max_price_for_display = $product->get_variation_price('max', true); // Max active price for display

// The min or max regular price.
$min_price = $product->get_variation_regular_price(); // Min regular price
$min_price_for_display = $product->get_variation_regular_price('min', true); // Min regular price for display
$max_price = $product->get_variation_regular_price('max'); // Max regular price
$max_price_for_display = $product->get_variation_regular_price('max', true); // Max regular price for display

// The min or max sale price.
$min_price = $product->get_variation_sale_price(); // Min sale price
$min_price_for_display = $product->get_variation_sale_price('min', true); // Min sale price for display
$max_price = $product->get_variation_sale_price('max'); // Max sale price
$max_price_for_display = $product->get_variation_sale_price('max', true); // Max sale price for display
