如何让woocommerce的产品标签层次化？

Question

我希望将woocommerce中的产品标签更改为分层显示。我试图寻找一个函数或钩子来改变这一点，但没有找到任何东西。

将感谢任何帮助或建议，以实现这一点。

谢谢。

Answer 1

在woocommerce 3.0.4上测试

function my_woocommerce_taxonomy_args_product_tag( $array ) {
    $array['hierarchical'] = true;
    return $array;
};
add_filter( 'woocommerce_taxonomy_args_product_tag', 'my_woocommerce_taxonomy_args_product_tag', 10, 1 );

找到了解决方案，如果有人想做同样的事情，请看这里：

function reregister_taxonomy_pro_tags() {
    # the post types that the taxonomy is registered to
    $post_types = array('product');
    # set this to the taxonomy name
    $tax_name = 'product_tag';
    # load the already created taxonomy as array so we can
    # pass it back in as $args to register_taxonomy
    $tax = (array)get_taxonomy($tax_name);

    if ($tax) {
        # adjust the hierarchical necessities
        $tax['hierarchical'] = true;
        $tax['rewrite']['hierarchical'] = true;

        # adjust the hierarchical niceties (these could be ignored)
        $tax['labels']['parent_item'] = sprintf(__("Parent %s"),
        $tax->labels->singular_name);
        $tax['labels']['parent_item_colon'] = sprintf(__("Parent %s:"),
        $tax->labels->singular_name);

        # cast caps to array as expected by register_taxonomy
        $tax['capabilities'] = (array)$tax['cap'];
        # cast labels to array
        $tax['labels'] = (array)$tax['labels'];
        # register the taxonomy with our new settings
        register_taxonomy($tax_name, array('product'), $tax);
    }
}

初始化具有延迟优先级的操作，以便加载其他分类

add_action('init'，'reregister_taxonomy_pro_tags'，9999)；

感谢上面的回答，为我节省了大量的研究，但您应该替换

    $tax['labels']['parent_item'] = sprintf(__("Parent %s"),
    $tax->labels->singular_name);
    $tax['labels']['parent_item_colon'] = sprintf(__("Parent %s:"),
    $tax->labels->singular_name);

至

$tax['labels']->parent_item = sprintf(__("Parent %s"),
$tax['labels']->singular_name);
$tax['labels']->parent_item_colon = sprintf(__("Parent %s:"),
$tax['labels']->singular_name);
