源代碼，循環(huán)了11遍。
{php $data = get_childcat(1);}
{loop $data $val}
<div class="index_st_list none">
<ul>
{m:lists field="title,url,yangyin,laoshi" catid="$val['catid']" limit="15" order="id DESC"}
{loop $data $v}
<li>
<div class="fl index_st_list_head">
<img src="<?php echo get_category($v['laoshi'], 'catimg');?>" alt="{$v[title]}"/>
</div>
<div class="fr index_st_list_txt">
<p><a href="{$v[url]}">{$v[title]}</a></p>
<div class="play paused" >
<audio preload="none" src="{$v[yangyin]}"></audio>
</div>
<span><a href="<?php echo get_category($v['laoshi'], 'pclink');?>">{php echo get_catname($v['laoshi']);}</a></span>
</div>
</li>
{/loop}
</ul>
<div class="index_st_list_more"><a href="{get_category($val['catid'], 'pclink')}">查看更多</a></div>
</div>
{/loop}仔細(xì)寫個自定義函數(shù) 限制調(diào)用字段，我需要四個字段catid，pclink，catname，catimg
/*獲取欄目信息*/
function get_cat($id,$fi){
$where = 'catid ='.$id;
$d = D('category')->field('catid,pclink,catname,catimg')->where($where)->select();
foreach ($d as $v){
return $v["$fi"];
}
}修改后代碼
{m:nav field="catid,pclink" where="parentid=1" limit="15"}
{loop $data $val}
<div class="index_st_list none">
<ul>
{m:lists field="title,thumb,url,yangyin,laoshi" catid="$val['catid']" limit="15" order="RAND()"}
{loop $data $v}
<li>
<div class="fl index_st_list_head">
<img src="{get_cat($v['laoshi'],'catimg')}" alt="{$v[title]}"/>
</div>
<div class="fr index_st_list_txt">
<p><a href="{$v[url]}">{$v[title]}</a></p>
<div class="play paused" >
<audio preload="none" src="{$v[yangyin]}"></audio>
</div>
<span><a href="{get_cat($v['laoshi'],'pclink')}">{get_cat($v['laoshi'],'catname')}</a></span>
</div>
</li>
{/loop}
</ul>
<div class="index_st_list_more"><a href="{$val['pclink']}">查看更多</a></div>
</div>
{/loop}這樣調(diào)用也會慢：
{get_category($val['catid'], 'pclink')}改成
$val['pclink']}
以前用虛擬主機(jī)的時候打開是不慢的。可能換了服務(wù)器配置不太好，打開速度很慢。瞎弄了一天，現(xiàn)在可以對付了。
