Question

我正在寻找一种方法来定位产品差异，并根据每个变体的属性修改其价格。下面的代码在某种程度上正朝着正确的方向发展，但我不是使用产品属性来定位变体，而是依靠将变体的当前价格与变量相匹配来定位它。它有效，但它留下了很大的错误空间，它有多模糊。

add_filter('woocommerce_get_price','change_price', 10, 2);
function change_price($price, $productd){

if (  $productd->product_type == 'variation' || $productd->product_type == 'variable' ) {

$basicmp3 = 25;

$vprice = get_post_meta( $productd->variation_id, '_regular_price',true);

    if ($vprice == $basicmp3) {

            $vprice2 = $vprice * .5;    
            return $vprice2;
    }
    else{           
         return $vprice;
    } 
}
}

Answer 1

当你在一个函数中运行一个woocommerce类时，需要调用一些全局函数。

 global $woocommerce; $product;
 $product_variation = new WC_Product_Variation($_POST['variation_id']);
 $regular_price = $product_variation->regular_price;

在另一个词中，不是因为你有$product作为参数，你可以使用类功能（它只是一个扁平的对象，如数组可）。您需要初始化类的新对象以使用$ newproductobject-＆gt; regular_price（）。

可能，如果您的代码是woocommerce类尚未加载的插件的一部分，那么您需要包含包含WC_Product _Variation类的文件。（不要以为它就是这样）

希望它有所帮助！

找到了一个有效的解决方案因为我不是代码大师，所以它可能有点臃肿，但我做到了！以下是基本版本，但这种灵活性将允许更多有用的功能，例如，对于共享某些属性的产品，按用户角色自动批量折扣变化价格。

add_filter('woocommerce_get_price','change_price', 10, 2);
function change_price($price, $productd){


global $post, $woocommerce;
$post_id = $variation->ID;


    $args = array(
                 'post_type'     => 'product_variation',
                 'post_status'   => array( 'private', 'publish' ),
                 'numberposts'   => -1,
                 'orderby'       => 'menu_order',
                 'order'         => 'asc',
                 'post_parent'   => $post->ID
             );
             $variations = get_posts( $args ); 

    //declare variables for later use        
    $demomp3 = '';
    $basicmp3 = '';

    foreach ( $variations as $variation ) {

                $variation_id           = absint( $variation->ID );$variable_id = $this['variation_id'];

使用以下脚本更新产品差异。点击此处获取详细说明。 https://www.pearlbells.co.uk/bulk-update-product-variation-price-woocommerce/

function getExistingProducts($updatedPrices,$skuArray) {

$loop = new WP_Query(array('post_type' => array('product', 'product_variation'), 'posts_per_page' => -1));

while ($loop->have_posts()) : $loop->the_post();

    $id = get_the_ID();
    $product = wc_get_product( $id );
    $sku = get_post_meta($id, '_sku', true);

    if( in_array( $sku, $skuArray  ) ) {

        $attributes = $product->get_attributes();
        $attributes['medium-quantity-price']['value'] = $updatedPrices[$sku][4];
        $attributes['low-quantity-price']['value'] = $updatedPrices[$sku][3];
      //  $attributes['v-low-quantity-price']['value'] = $updatedPrices[$sku][2];
        update_post_meta( $id,'_product_attributes',$attributes);
        echo ' Update Sku : '.$sku.' '.PHP_EOL;

    }

endwhile;
