获取 WooCommerce 中的所有产品类别

Get all product categories in WooCommerce

我正在尝试在 WooCommerce 中获取产品类别,但 get_terms() 功能对我不起作用。我得到一个空数组。

我做错了什么?如何获取所有 Woocommerce 产品类别术语?

产品类别是 WooCommerce 产品使用的 "custom taxonomy" product_cat

您需要使用get_terms(),使用正确的分类法,这样:

// Get Woocommerce product categories WP_Term objects
$categories = get_terms( ['taxonomy' => 'product_cat'] );

// Getting a visual raw output
echo '<pre>'; print_r( $categories ); echo '</pre>';

您还可以使用 get_terms() 获取空产品类别,例如:

$categories = get_terms( ['taxonomy' => 'product_cat', 'hide_empty' => false] );

经过测试并有效(WordPress 3.5+ 和 WooCommerce 2.4+)……两者都应该适合您。

你会得到类似的东西:

Array
(
    [0] => WP_Term Object
        (
            [term_id] => 83
            [name] => Uncategorized
            [slug] => uncategorized
            [term_group] => 0
            [term_taxonomy_id] => 83
            [taxonomy] => product_cat
            [description] => 
            [parent] => 0
            [count] => 5
            [filter] => raw
            [meta_value] => 1
        )

    [2] => WP_Term Object
        (
            [term_id] => 11
            [name] => Tshirts
            [slug] => tshirts
            [term_group] => 0
            [term_taxonomy_id] => 11
            [taxonomy] => product_cat
            [description] => 
            [parent] => 0
            [count] => 13
            [filter] => raw
            [meta_value] => 2
        )
    // … and so on …
)

我从所有产品类别中取出我的,也排除了我不想显示的类别

$taxonomy = "product_cat";
$terms = get_terms($taxonomy, array('orderby' => 'slug', 'hide_empty' => false, 'exclude' => array( 19 ))); //Exclude Specific Category by ID

foreach ($terms as $term) {
    $thumbnail_id = get_woocommerce_term_meta($term->term_id, 'thumbnail_id', true);
    $image = wp_get_attachment_url($thumbnail_id); ?>

    <div class="col-12 col-md-3">
        <div class="cat-item drop-shadow white-b padding-20 align-center margin-bottom-30">
            <?php 
                echo '<h3 class="uppercase strong blue-2-c margin-bototm-20 equal-height">' . $term->name . '</h3>';
                echo '<div class="item-thumbnail" style="background: url('.$image.');height:150px"></div>'; 
                echo '<a href="' . get_term_link($term->name, $taxonomy) . '" class="button color-blue-2-radial">View Range</a>';
            ?>
        </div>
    </div>
