For my WC product pages, I need to add a class to the body tag so that I can perform some custom styling. Here's the function I'm creating for this...

function my_add_woo_cat_class($classes) {

    $wooCatIdForThisProduct = "?????"; //help!

    // add 'class-name' to the $classes array

    // Add specific CSS class by filter
    add_filter('body_class','my_add_woo_cat_class');
}

...但是我如何获得 WooCommerce cat ID?

...but how do I get the WooCommerce cat ID?

推荐答案

一个 WC 产品可能不属于一个、一个或多个 WC 类别.假设您只想获得一个 WC 类别 ID.

A WC product may belong to none, one or more WC categories. Supposing you just want to get one WC category id.

global $post;
$terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($terms as $term) {
    $product_cat_id = $term->term_id;
    break;
}

请查看 WooCommerce 插件templates/single-product/"文件夹中的 meta.php 文件.

Please look into the meta.php file in the "templates/single-product/" folder of the WooCommerce plugin.

<?php echo $product->get_categories( ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', sizeof( get_the_terms( $post->ID, 'product_cat' ) ), 'woocommerce' ) . ' ', '.</span>' ); ?>
