Wordpress 在分类中使用逗号

问题描述 投票:0回答:1

在 PHP 8 发布之前,我可以在自定义标签中用逗号替换“--”。使用以下代码。

if(!is_admin()){ // make sure the filters are only called in the frontend
    
    $custom_taxonomy_type = 'winners_name'; // here goes your taxonomy type
    
    function comma_taxonomy_filter($tag_arr){
        global $custom_taxonomy_type;
        $tag_arr_new = $tag_arr;
        if($tag_arr->taxonomy == $custom_taxonomy_type && strpos($tag_arr->name, '--')){
            $tag_arr_new->name = str_replace('--',', ',$tag_arr->name);
        }
        return $tag_arr_new;    
    }
    add_filter('get_'.$custom_taxonomy_type, comma_taxonomy_filter);
    
    function comma_taxonomies_filter($tags_arr){
        $tags_arr_new = array();
        foreach($tags_arr as $tag_arr){
            $tags_arr_new[] = comma_taxonomy_filter($tag_arr);
        }
        return $tags_arr_new;
    }
    add_filter('get_the_taxonomies',    comma_taxonomies_filter);
    add_filter('get_terms',             comma_taxonomies_filter);
    add_filter('get_the_terms',         comma_taxonomies_filter);
}

PHP 更新后,出现以下错误。 PHP 致命错误: 未捕获的错误: /nas/content/live/stagelask/wp-content/themes/Avada-Child-Theme/functions.php:31 中未定义常量“comma_taxonomy_filter” 堆栈跟踪: #0 /nas/content/live/stagelask/wp-settings.php(591): include() #1 /nas/content/live/stagelask/wp-config.php(119): require_once('/nas/content/li...') #2 /nas/content/live/stagelask/wp-load.php(50): require_once('/nas/content/li...') #3 /nas/content/live/stagelask/wp-blog-header.php(13): require_once('/nas/content/li...') #4 /nas/content/live/stagelask/index.php(17): require('/nas/content/li...') #5 {主要} 扔在第 31 行 /nas/content/live/stagelask/wp-content/themes/Avada-Child-Theme/functions.php 中,参考:https://stagelask.wpengine.com

我首先做了一些研究,看看是否有解决办法。然后我尝试(未成功)定义常量 comma_taxonomy_filter。

如有任何帮助,我们将不胜感激。

谢谢, 马克

只需将

add_filter()
调用的第二个参数固定为字符串即可:

add_filter('get_the_taxonomies',    'comma_taxonomies_filter');
add_filter('get_terms',             'comma_taxonomies_filter');
add_filter('get_the_terms',         'comma_taxonomies_filter');
