獲取產品變體和修改價格 - woocommerce

Question

我在尋找一種方法來定位產品變體，並根據每個變體的屬性修改其價格。下面的代碼有點朝着正確的方向前進，但是我不是使用產品屬性來定位變化，而是依靠將變體的當前價格與變量進行匹配來實現目標。它的工作原理，但它有多麼模糊的錯誤空間。

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

工作解決方案當你在一個函數運行woocommerce類，有一個需要調用一些全球性的。

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

換句話說，這不是因爲你有$product作爲參數，你可以使用類函數（它就像一個陣列中的「扁平化」的對象都可以）。您需要初始化類的新對象以使用$ newproductobject-> regular_price（）。

如果您的代碼是woocommerce類尚未加載的插件的一部分，那麼您可能需要包含包含類WC_Product _Variation的文件。 （不要認爲是這樣）

希望它有幫助！

找到了一個工作解決方案。這可能有點臃腫，因爲我不是代碼大師，但我做到了！以下是一個基本版本，但這種靈活性將允許更多有用的功能，例如自動批量折扣具有特定屬性的產品的用戶角色的變化價格。

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 = ''; 
    $basicwav = ''; 
    $premiummp3 = ''; 
    $premiumwav = ''; 
    $syncmp3 = ''; 
    $syncwav = ''; 

    foreach ($variations as $variation) { 

       $variation_id   = absint($variation->ID);$variable_id = $this['variation_id']; 
       $variation_post_status = esc_attr($variation->post_status); 
       $variation_data   = get_post_meta($variation_id); 
       $variation_data['variation_post_id'] = $variation_id; 

       //find attributes 
       $option1 = 'pa_license-options'; 
       $option2 = 'pa_delivery-format'; 
       $getmeta1 = get_post_meta($variation_id , 'attribute_'.$option1, true); 
       $getmeta2 = get_post_meta($variation_id , 'attribute_'.$option2, true);

       $license = $attribute1->name; 
       $format = $attribute2->name; 


       //get the prices of each variation by the attribute combinations they have

      if ($regprice == $demomp3) { 

        //apply price adjustment and return the new value

使用以下腳本更新產品變體。點擊這裏查看詳細說明。 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;
