如何通过分类术语获得产品变体ID?

例如,如果我有两个分类法及其术语:

1) Size: medium, large
2) Color: blue, green

我的产品变体:

Variation id 1: medium > blue
Variation id 2: medium > green
Variation id 3: large > blue
Variation id 4: large > green

我想获取此词语组合medium > green的变体ID。

以下函数使用非常简单的SQL查询从变量产品中获取已定义产品属性“颜色”和“尺寸”项的变量的变体ID:

function get_product_variation_id( $size, $color, $product_id = 0 ) {
    global $wpdb;

    if ( $product_id == 0 )
        $product_id = get_the_id();

    return $wpdb->get_var( "
        SELECT p.ID
        FROM {$wpdb->prefix}posts as p
        JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
        JOIN {$wpdb->prefix}postmeta as pm2 ON p.ID = pm2.post_id
        WHERE pm.meta_key = 'attribute_pa_color'
        AND pm.meta_value LIKE '$color'
        AND pm2.meta_key = 'attribute_pa_size'
        AND pm2.meta_value LIKE '$size'
        AND p.post_parent = $product_id
    " );
}

代码进入您的活动子主题(或活动主题)的function.php文件中。经过测试,可以正常工作。


用法(2个案例)

1)从已定义的变量产品ID(其中746是父变量产品ID):

$variation_id = get_product_variation_id( 'large', 'blue', 746 );

2)在可变产品单一产品页面(无需定义可变产品ID)

$variation_id = get_product_variation_id( 'large', 'blue' );

我还没有测试过,但是应该已经准备好了或者可以发货了。

function get_variation_by($size, $color) {
  $args = array(
    'post_type' => 'product',
    'numberposts' => -1,
  );
  $product_posts = get_posts( $args );

  foreach ( $product_posts as $single_product_post ) {
    $_product = wc_get_product( $single_product_post->ID );
    if ($product_s->product_type != 'variable') continue;

    $avail_vars = $_product->get_available_variations();
    foreach ($avail_vars as $v)
      if ($v["attributes"]["attribute_pa_size"] == $size
          && $v["attributes"]["attribute_pa_color"] == $color)
        return $v;
  }
  return null;
}

$variation = get_variation_by( "large", "green");
$variation_id = $variation->variation_id;

如果已经具有变量product的product_id,则可以这样简化:

function get_variation_by($variable_product_id, size, $color) {
  $var_prod = wc_get_product( $variable_product_id );        
  $avail_vars = $var_prod->get_available_variations();

  foreach ($avail_vars as $v)
    if ($v["attributes"]["attribute_pa_size"] == $size
        && $v["attributes"]["attribute_pa_color"] == $color)
      return $v;

  return null;
}
