Question

我正在开展一个项目，我需要在页面中列出所有隐藏的产品。我已经创建了一个短代码，我使用了以下元查询，但它不起作用。

$meta_query = array(
    'key'     => '_visibility',
    'value'   => array('hidden'),
    'compare' => 'IN'
);

知道为什么这不起作用？提前感谢您的帮助。

Answer 1

$args = array(
    'post_type'     => 'product',
    'meta_key'      => '_visibility',
    'meta_value'    => 'hidden'
);

$query = new WP_Query($args);

然后你通常的循环对我有效：）

Answer 2

WooCommerce 3+的可见性为changed to a taxonomy instead of post meta，如果您使用WC()->query->get_tax_query()函数调用来构建args，则只需从设置tax_query中删除该调用即可。

如果您无权访问args或它们的构建方式并且已通过get_tax_query运行，则可以使用过滤器删除NOT IN征税查询以提高可见性：

add_filter( 'woocommerce_product_query_tax_query', 'smyles_show_all_products' );
// do something that calls some fn that makes product query
remove_filter( 'woocommerce_product_query_tax_query', 'smyles_show_all_products' );

function smyles_show_all_products( $tax_query ) {

        foreach( (array) $tax_query as $t_index => $t_query ){

            if( isset( $t_query['taxonomy'], $t_query['operator'] ) && $t_query['taxonomy'] === 'product_visibility' && $t_query['operator'] === 'NOT IN' ){
                unset( $tax_query[ $t_index ] );
                break;
            }

        }

        return $tax_query;
    }

Answer 3

使用此

$f1 = -1;  // Last value read
$f2 = -1;  // second to last value
$f3 = -1;


$a = array(1, 2, 3, 17, 27, 44, 45, 47, 49);

foreach ($a as $v) {
    $f3 = $f2;
    $f2 = $f1;
    $f1 = $v;
    if ($v == 45){
        # tricky part
        print "The last three v's were: " . $f1 . ", " . $f2 . ", " . $f3 . "\n";
    }
}
