如何在woocommerce中以编程方式设置产品属性变体价格？

Question

我有一个产品属性变化，有选项-小-20美元中等-25美元大-30美元

因为商店里的所有产品都有相同的价格。

如何以编程方式设置属性值的价格？

当我将3个属性变体按钮添加为变体时，它们会显示在产品页面上。

如何更改产品的价格时，"小"选项选择编程方式，而不是设置价格的变化选项在管理面板。

根据我们的理解，想要添加不同尺寸和不同价格的产品。

有2种方式：

1.您可以从仪表板添加如下内容：https://www.ostraining.com/blog/woocommerce/product-variations/

您可以像这样以编程方式添加：

function insert_product ($product_data)
{
    $post = array( // Set up the basic post data to insert for our product

     'post_author'  => 1,
     'post_content' => $product_data['description'],
     'post_status'  => 'publish',
     'post_title'   => $product_data['name'],
     'post_parent'  => '',
     'post_type'    => 'product'
 );

 $post_id = wp_insert_post($post); // Insert the post returning the new post id

 if (!$post_id) // If there is no post id something has gone wrong so don't proceed
 {
     return false;
 }

 update_post_meta($post_id, '_sku', $product_data['sku']); // Set its SKU
 update_post_meta( $post_id,'_visibility','visible'); // Set the product to visible, if not it won't show on the front end

 wp_set_object_terms($post_id, $product_data['categories'], 'product_cat'); // Set up its categories
 wp_set_object_terms($post_id, 'variable', 'product_type'); // Set it to a variable product type

  insert_product_attributes($post_id, $product_data['available_attributes'], $product_data['variations']); // Add attributes passing the new post id, attributes & variations
  insert_product_variations($post_id, $product_data['variations']); // Insert variations passing the new post id & variations
}


 function insert_product_attributes ($post_id, $available_attributes, $variations)
{
   foreach ($available_attributes as $attribute) // Go through each attribute
   {
     $values = array(); // Set up an array to store the current attributes values.

     foreach ($variations as $variation) // Loop each variation in the file
     {
         $attribute_keys = array_keys($variation['attributes']); // Get the keys for the current variations attributes

         foreach ($attribute_keys as $key) // Loop through each key
         {
             if ($key === $attribute) // If this attributes key is the top level attribute add the value to the $values array
             {
                 $values[] = $variation['attributes'][$key];
             }
         }
     }
     $values = array_unique($values); // Filter out duplicate values

     wp_set_object_terms($post_id, $values, 'pa_' . $attribute);
 }

 $product_attributes_data = array(); // Setup array to hold our product attributes data

 foreach ($available_attributes as $attribute) // Loop round each attribute
 {
     $product_attributes_data['pa_'.$attribute] = array( // Set this attributes array to a key to using the prefix 'pa'

         'name'         => 'pa_'.$attribute,
         'value'        => '',
         'is_visible'   => '1',
         'is_variation' => '1',
         'is_taxonomy'  => '1'

     );
 }

 update_post_meta($post_id, '_product_attributes', $product_attributes_data); // Attach the above array to the new posts meta data key '_product_attributes'
}

function insert_product_variations ($post_id, $variations)
{
  foreach ($variations as $index => $variation)
   {
     $variation_post = array( // Setup the post data for the variation

         'post_title'  => 'Variation #'.$index.' of '.count($variations).' for product#'. $post_id,
         'post_name'   => 'product-'.$post_id.'-variation-'.$index,
         'post_status' => 'publish',
         'post_parent' => $post_id,
         'post_type'   => 'product_variation',
         'guid'        => home_url() . '/?product_variation=product-' . $post_id . '-variation-' . $index
     );

     $variation_post_id = wp_insert_post($variation_post); // Insert the variation

     foreach ($variation['attributes'] as $attribute => $value) // Loop through the variations attributes
     {
         $attribute_term = get_term_by('name', $value, 'pa_'.$attribute); // We need to insert the slug not the name into the variation post meta

         update_post_meta($variation_post_id, 'attribute_pa_'.$attribute, $attribute_term->slug);
     }

     update_post_meta($variation_post_id, '_price', $variation['price']);
     update_post_meta($variation_post_id, '_regular_price', $variation['price']);
    }
 }

 function insert_products ($products)
 {
    if (!empty($products)) // No point proceeding if there are no products
    {
       array_map('insert_product', $products); // Run 'insert_product' function from above for each product
    }
 }
 $json = file_get_contents('product-data.json'); // Get json from sample file
// $products_data = json_decode($json_file, true); // Decode it into an array
echo json_last_error();

// if(get_magic_quotes_gpc()){
   //  $d = stripslashes($json);
 // }else{
  //  $d = $json;
 // }
 $d = json_decode($d,true);
 $products_data = json_decode( preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $json), true );
 echo "<h1>json</h1>";
 echo "<pre>";
 print_r($json);
 echo "</pre>";
 echo "<h1>Product data</h1>";
 echo "<pre>";
 var_dump($products_data);
 echo "</pre>";

 insert_products($products_data);

其中$product_数据样本：

$product_data = array(
    'sku' => '123SKU',
    'categories' => array('size', 'color'),
    'available_attributes' => array('size', 'color'),
    'variations' => array( 
        'size' => array(
            'attributes' => array( 'XL', 'M', 'S' ), 
        ),
        'color' => array(
            'attributes' => array( 'Blue', 'Red', 'Green' )  
        )
    )
 )

 insert_products($products_data); 

注意：您可以创建product-data.json和导入产品，或者您可以创建$product_data = (); 并设置insert_products（）函数。
