以编程方式添加的变体在单击更新按钮后才会显示

这开始让我头痛，所以希望这里的人能帮助我，我们可以一起帮助其他有同样问题的人！

我构建了一个插件，可以自动为WooCommerce生成产品变体。这一切似乎都很好，除了一件事。新的变体在前端不可见，当我查看产品编辑页面时，它们如下所示：

当我点击更新按钮并保存产品时，它得到了神奇的修复。在前端和后端都可以看到变化，现在看起来是这样的：

The code

// Get the Variable product object (parent)
$product = wc_get_product($parent_id);

$variation_post = array(
    \'post_title\'  => $product->get_title(),
    \'post_name\'   => \'product-\'.$parent_id.\'-variation\',
    \'post_status\' => ($enable_variations == "yes") ? \'publish\' : \'private\',
    \'post_parent\' => $parent_id,
    \'post_type\'   => \'product_variation\',
    \'guid\'        => $product->get_permalink()
);

// Creating the product variation
$variation_id = wp_insert_post( $variation_post, true );

$fields = array(
    \'_manage_stock\'                 => \'yes\',
    \'_backorders\'                   => $backorders,
    \'_stock_status\'                 => $stock_status,
    \'_stock\'                        => $stock,
    \'_regular_price\'                => $price,
    \'_price\'                        => $price,
);

foreach ( $fields as $meta_key => $meta_value ) {
    update_post_meta($variation_id, $meta_key, $meta_value);
}

// Add attribute 1 to variation
wp_set_post_terms( $variation_id, sanitize_title($attribute_value), "pa_attribute_1", true );
update_post_meta( $variation_id, \'attribute_pa_attribute_1\', sanitize_title($attribute_value));

// Add attribute 2 to variation
wp_set_post_terms( $variation_id, sanitize_title($attribute_value), "pa_attribute_2", true );
update_post_meta( $variation_id, \'attribute_pa_attribute_2\', sanitize_title($attribute_value));

// Add attribute 3 to variation
wp_set_post_terms( $variation_id, sanitize_title($attribute_value), "pa_attribute_3", true );
update_post_meta( $variation_id, \'attribute_pa_attribute_3\', sanitize_title($attribute_value));

wc_delete_product_transients($variation_id);

我错过了什么？在产品上单击“更新”时会发生什么情况？已经尝试使用$product->save（）和删除过渡，就像web上大多数主题中回答的那样。

// Create an array of the attributes we want to add $attributes = array( "attribute_1" => array( "slug" => "attribute_1", "label" => "Name of attribute 1", ), "attribute_2" => array( "slug" => "attribute_2", "label" => "Name of attribute 2", ), "attribute_3" => array( "slug" => "attribute_3", "label" => "Name of attribute 3", ), ); // Add the attributes to WooCommerce foreach($attributes as $attribute){ if(!get_taxonomy("pa_" . $attribute["slug"])) { $result = wc_create_attribute(array( "name" => $attribute["label"], "slug" => $attribute["slug"], "type" => "select", )); } } // Create an array with all the terms $attributes_values["attribute_1"] = array("value 1", "value 2", "value 3"); $attributes_values["attribute_2"] = array("value 1", "value 2", "value 3"); $attributes_values["attribute_3"] = array("value 1", "value 2", "value 3"); // Iterate over our attributes map,containing attributes that we want to sync foreach($attributes_values as $attribute => $values ){ // Iterate over possible values for the attribute and insert them. foreach($values as $value) { if(!term_exists($value, wc_attribute_taxonomy_name($attribute))){ wp_insert_term($value, wc_attribute_taxonomy_name($attribute), array(\'slug\' => sanitize_title($term))); } } }

// Get the Variable product object (parent) $product = wc_get_product($variableProductID); $variation_post = array( \'post_title\' => $product->get_title(), \'post_name\' => \'product-\'.$variableProductID.\'-variation\', \'post_status\' => \'publish\', \'post_parent\' => $variableProductID, \'post_type\' => \'product_variation\', \'guid\' => $product->get_permalink() ); // Creating the product variation $variation_id = wp_insert_post($variation_post, true); if (is_wp_error($variation_id)) { // Error handling } // Get an instance of the WC_Product_Variation object $variation = new \\WC_Product_Variation($variation_id); // Add attributes to variation update_post_meta($variation_id, \'attribute_pa_device_brand\', sanitize_title($action["arguments"]["device_brand"])); update_post_meta($variation_id, \'attribute_pa_device_model\', sanitize_title($action["arguments"]["device_model"])); update_post_meta($variation_id, \'attribute_pa_case_type_colour\', sanitize_title($action["arguments"]["case_type_colour"])); $variation->set_price($action[\'arguments\'][\'price\']); $variation->set_regular_price($action[\'arguments\'][\'price\']); $variation->set_stock_quantity($action[\'arguments\'][\'stock\']); $variation->set_manage_stock(true); $variation->set_stock_status(); $variation->set_backorders($action[\'arguments\'][\'backorders\']); $variation->save();
