下面的代码似乎根本没有返回图像url，chrome inspector表示源代码未知
foreach ($subcategories as $subcategory) {
$link = get_term_link( $subcategory->slug, $subcategory->taxonomy );
$thumbnail_id = get_term_meta( $subcategory->term_id, \'thumbnail_id\', true );
$image= wp_get_attachment_url( $thumbnail_id );
echo \'<img src="\' . $image . \'" width="50" height="50" />\';
完整代码
// Adding Child Category List to Main Category Display Grid
add_action(\'woocommerce_after_subcategory\', \'woocommerce_subcats_from_parentcat_by_ID\', 20);
function woocommerce_subcats_from_parentcat_by_ID($category) {
$parent_category_ID = $category->term_id;
$args = array(
\'hierarchical\' => 1,
\'show_option_none\' => \'\',
\'hide_empty\' => 0, // Set to 0 to show empty categories and 1 to hide them
\'parent\' => $parent_category_ID,
\'taxonomy\' => \'product_cat\'
);
$subcategories = get_categories($args);
echo \'<ul class="woo_subcategory_list">\';
foreach ($subcategories as $subcategory) {
$link = get_term_link( $subcategory->slug, $subcategory->taxonomy );
$thumbnail_id = get_term_meta( $subcategory->term_id, \'thumbnail_id\', true );
$image= wp_get_attachment_url( $thumbnail_id );
echo \'<img src="\' . $image . \'" width="50" height="50" />\';
}
echo \'</ul>\';
}

然后检查如下：
$thumb_id = get_woocommerce_term_meta( $subcategory->term_id, \'thumbnail_id\', true );
$term_img = wp_get_attachment_url( $thumb_id );
像这样检查
$meta = get_term_meta( $subcategory->term_id );
var_dump($meta);
$thumb_id = $meta[\'thumbnail_id\'][0];
$term_img = wp_get_attachment_url( $thumb_id );
你也会这样
$thumbnail_id = get_term_meta( $subcategory->term_id, \'thumbnail_id\', true );
$image = wp_get_attachment_url( $thumbnail_id );
