显示具有特定woo Commerce类别的产品的自定义文本

我正在尝试显示特定woo Commerce类别中产品的自定义文本。这是我添加到function.php的代码, 但它在类别页面而非产品页面中显示了文本。

add_action( 'woocommerce_after_main_content', 'add_my_text' );
function add_my_text() {
    if ( is_product_category( 'category1' ) ) {
        echo '<p>This is my extra text.</p>';
    }    
}

ps。在开头添加” if(function_exists(add_action))”有什么好处？

要在此特定类别的”产品”页面上显示文本, 你应添加条件标签is_product()并使用has_term()函数检查其是否具有正确的类别, 如下所示：

add_action( 'woocommerce_after_main_content', 'add_my_text' );
function add_my_text() {
    //1st grab the product/post object for the current page if you don't already have it:
    global $post;
    //2nd you can get the product category term objects (the categories) for the product
    $terms = wp_get_post_terms( $post->ID, 'product_cat' );
    foreach ( $terms as $term ) $categories[] = $term->slug;
    //Then we just have to check whether a category is in the list:
    if ( is_product_category( 'category1' ) || is_product() && in_array( 'category1', $categories ) ) {
        echo '<p>This is my extra text.</p>';
    }    
}

对于if(function_exists(…问题, 这是出于向后兼容性的问题, 如此答案中所述：https://wordpress.stackexchange.com/a/111318/136456

这有效：

add_action( 'woocommerce_after_single_product_summary', 'add_text' );

function add_text() {

if ( has_term( 'nail', 'product_cat' ) ) {
echo 'Something';
} elseif ( has_term( 'tables', 'product_cat' ) ) {
echo 'Something else';
}

}
