我在函数中使用以下代码。我的主题的php，隐藏用于组织帖子的特定类别，并从帖子本身及其类别列表填充滑块：

function the_category_filter($thelist,$separator=\' \') {
 // list the IDs of the categories to exclude
 $exclude = array(1,32,42,4);
 // create an empty array
 $exclude2 = array();

 // loop through the excluded IDs and get their actual names
 foreach($exclude as $c) {
      // store the names in the second array
      $exclude2[] = get_cat_name($c);
 }

 // get the list of categories for the current post     
 $cats = explode($separator,$thelist);
 // create another empty array      
 $newlist = array();

 foreach($cats as $cat) {
      // remove the tags from each category
      $catname = trim(strip_tags($cat));

      // check against the excluded categories
      if(!in_array($catname,$exclude2))

      // if not in that list, add to the new array
      $newlist[] = $cat;
 }
 // return the new, shortened list
 return implode($separator,$newlist);
}

// add the filter to \'the_category\' tag
add_filter(\'the_category\',\'the_category_filter\', 1, 32, 42, 4);

这很好，但它也隐藏了后期编辑后端中的类别。我可以看到勾选框，但类别名称已隐藏。

是否有人可以建议对上述代码进行调整，以保留其在前端隐藏类别的功能，但保持类别在编辑后窗口/WP后端可见？

// Exclude categories.
