WooCommerce get products by attribute查询

Question

我有一个具有颜色属性的产品。属性值为红色、蓝色和绿色。我正在尝试创建自定义搜索，但我无法获取用于拉取任何产品的查询。

$args =  array(
    'post_type'      => array('product'),
    'post_status'    => 'publish',
    'posts_per_page' => -1,
    'meta_query'     => array( 
        array(
            'key' => '_visibility',
            'value' => array('catalog', 'visible'),
            'compare' => 'IN',  
        ) 
    ),
    'tax_query'      => array( 
        array(
            'taxonomy'        => 'product',
            'field'           => 'slug',
            'terms'           =>  array('blue', 'red', 'green'),
            'operator'        => 'IN',
        ),
    )
);

$products = new WP_Query( $args );

我哪里错了？

Answer 1

产品属性颜色的正确分类是'pa_color'，，因此正确的工作查询是：

// The query
$products = new WP_Query( array(
   'post_type'      => array('product'),
   'post_status'    => 'publish',
   'posts_per_page' => -1,
   'meta_query'     => array( array(
        'key' => '_visibility',
        'value' => array('catalog', 'visible'),
        'compare' => 'IN',
    ) ),
   'tax_query'      => array( array(
        'taxonomy'        => 'pa_color',
        'field'           => 'slug',
        'terms'           =>  array('blue', 'red', 'green'),
        'operator'        => 'IN',
    ) )
) );

// The Loop
if ( $products->have_posts() ): while ( $products->have_posts() ):
    $products->the_post();
    $product_ids[] = $products->post->ID;
endwhile;
    wp_reset_postdata();
endif;

// TEST: Output the Products IDs
print_r($product_ids);

这段代码已经过测试，可以正常工作。您将获得所有具有颜色属性的产品，这些产品的值(术语)为'blue‘、'red’和'green'…

从WooCommerce 3开始，产品可见性由自定义分类法product_visibility处理。您可以看到以下相关线程：
