Php wordpress-保存后自动插入术语slug作为标记

更新，代码正在运行

我有下面的代码，但它并没有像预期的那样工作。它应该采用分类法分类法名称中的术语，仅适用于自定义文章类型自定义文章类型和添加为标记

这是未经测试的，但它应该是朝着正确方向迈出的一步，我已经做了一些调整，并将发表评论：

<?php
add_action('save_post','add_tags_auto');
function add_tags_auto($post_id) {
    $post = get_post($post_id);

    // bail if this isn't a type of post we want to auto-tag
    if($post->post_type != 'CUSTOM_POST_TYPE')
        return false;

    // --------------------------------------------------
    // get the list of tag names from the post
    // --------------------------------------------------
    $tagNames = array();
    $tags     = get_the_tags($post_id);

    foreach($tags as $tag)
        $tagNames[] = $tag->name;

    // --------------------------------------------------
    // get the list slugs from terms in the post, any
    // slugs that aren't alredy a tag, will be marked for
    // addition automatically
    // --------------------------------------------------
    $tagsToAdd = array();
    foreach(get_the_terms($post_id, 'TAXONOMY_NAME') as $term)
        if(!in_array($term->slug, $tagNames))
            $tagsToAdd[] = $term->slug;

    // if we have some new tags to add, let's do that now
    if(!empty($tagsToAdd))
        wp_add_post_tags($post_id, implode(',', $tagsToAdd));
}

是否有限制标签数量的方法，您可以退出调用
$tagsToAdd[]=$term->slug的foreach。假设您有一个变量，称它为
$iMaxTags
（例如，您可以从数据库中填充它），如果（$i<$iMaxTags&&！in_array（$term->slug，$tagNames）），循环中的条件将变为
；然后还记得将foreach更改为
为$i=>$term
。但是，请注意，这是一种相当粗糙的限制方法。一个实用的解决方案可能会尝试以某种方式更智能地过滤它们。
<?php
add_action('save_post','add_tags_auto');
function add_tags_auto($post_id) {
    $post = get_post($post_id);

    // bail if this isn't a type of post we want to auto-tag
    if($post->post_type != 'CUSTOM_POST_TYPE')
        return false;

    // --------------------------------------------------
    // get the list of tag names from the post
    // --------------------------------------------------
    $tagNames = array();
    $tags     = get_the_tags($post_id);

    foreach($tags as $tag)
        $tagNames[] = $tag->name;

    // --------------------------------------------------
    // get the list slugs from terms in the post, any
    // slugs that aren't alredy a tag, will be marked for
    // addition automatically
    // --------------------------------------------------
    $tagsToAdd = array();
    foreach(get_the_terms($post_id, 'TAXONOMY_NAME') as $term)
        if(!in_array($term->slug, $tagNames))
            $tagsToAdd[] = $term->slug;

    // if we have some new tags to add, let's do that now
    if(!empty($tagsToAdd))
        wp_add_post_tags($post_id, implode(',', $tagsToAdd));
