请告诉我您知道如何为所有产品添加标签。我试过了wp_set_object_terms($post->id, array(\'nou\',\'product_tag2\',\'product_tag3\'), \'product_tag\'); 但不起作用。我的全部代码是：
function add_tags() {
$args = array(
\'post_type\' => \'product\',
\'posts_per_page\' => -1
);
$loop = new WP_Query( $args );
if ( $loop->have_posts() ): while ( $loop->have_posts() ): $loop->the_post();
wp_set_object_terms($post->id, array(\'nou\',\'product_tag2\',\'product_tag3\'), \'product_tag\');
$terms = get_the_terms( $post->ID, \'product_tag\' );
$aromacheck = array();
foreach ( $terms as $term ) {
$aromacheck[] = $term->slug;
echo $term->slug;
}
if (in_array ( "nou", $aromacheck ) ) {
echo "I have the value";
}
endwhile; endif; wp_reset_postdata();
}
add_action(\'init\', \'add_tags\');

这就是解决方案
function add_tags_products()
{
global $product;
$args = array(
\'post_type\' => \'product\', // your product post type
\'posts_per_page\' => - 1,
);
$posts = get_posts($args);
foreach ($posts as $post):
setup_postdata($post);
// check to see if the post has any tags
if( ! has_term( \'\', \'product_tag\', $post->ID ) ) :
// create the term
wp_set_object_terms($post->ID, array(\'nou\'), \'product_tag\');
endif;
wp_reset_postdata();
endforeach;
}
add_action(\'init\', \'add_tags_products\');
