space_userabout.htm里也有，和上面的代碼形式相同。
{lang }有區(qū)別，取消收聽{lang follow_del}，收聽{lang follow_add}TA。
space_card也有這個東西，但是代碼稍有不同，不同uid有區(qū)分，如下。
<!--{if helper_access::check_module('follow')}-->
<a href="home.php?mod=spacecp&ac=follow&op={if !empty($follow)}del{else}add{/if}&hash={FORMHASH}&fuid=$space[uid]" id="card_followmod_$space[uid]" onclick="showWindow(this.id, this.href, 'get', 0)" class="xi2"><!--{if !empty($follow)}-->{lang follow_del}<!--{else}-->{lang follow_add}TA<!--{/if}--></a>
<!--{/if}-->
