wordpress 从 get_the_tag_list 中排除标签 [英] wordpress exclude tag from get_the_tag_list

问题描述

虽然我使用自定义模板标签输出单个帖子标签:

While I use custom template tag to output single post tags:

<?php
echo get_the_tag_list('<p class="text-muted"><i class="fa fa-tags"></i> ',', ','</p>');
?>

如何从标签列表中排除定义的标签名称?

How to exclude defined tag name from the tag list?

推荐答案

好吧，get_the_tag_list 中没有过滤器可以删除术语，但在内部它需要 get_the_terms，因此您可以在那里添加过滤器.

Well there is no filter to remove terms in get_the_tag_list but internally it calls for get_the_terms so you can add filter there.

考虑这个例子:-

add_filter('get_the_terms', 'exclude_terms');
echo get_the_tag_list('<p class="text-muted"><i class="fa fa-tags">',', ','</i></p>');
remove_filter('get_the_terms', 'exclude_terms');

在 get_the_terms 上添加过滤器，并在回显列表后将其删除.因为它可能在页面上被多次调用.

Add a filter on get_the_terms and remove it after echoing list. Because it may be called on the page multiple times.

并在回调函数中通过 ID 或 slug 删除术语

And in callback function remove terms by IDs or slugs

function exclude_terms($terms) {
    $exclude_terms = array(9,11); //put term ids here to remove!
    if (!empty($terms) && is_array($terms)) {
        foreach ($terms as $key => $term) {
            if (in_array($term->term_id, $exclude_terms)) {
                unset($terms[$key]);
            }
        }
    }

    return $terms;
}
