以下函数通常在类别循环中使用，以返回每个类别的描述。我试图在查看类别登录页（mysite/category/somecategory）时使用它返回单个类别的描述。

如何传递表示类别的等效对象？

在页眉上。php

if(is_archive()) {
//get the category description
echo get_cat_desc(get_query_var( \'category\' ))
}

function get_cat_desc($category){
  $the_description = strip_tags($category->description);
  if(strlen($the_description) > 200 ) 
return  SUBSTR( $the_description,0,STRPOS( $the_description,".",200)+1);
else return  $the_description;
}

function my_category_index(){
$categories=get_categories(\'exclude=1&exclude_tree=1\');
foreach($categories as $category) {echo ce4_get_cat_desc($category);}
}
