<code><span class="badge">{$vo.tags}</span>
</code>
Copy after login
Copy after login

{$vo.tags} 是一个a|b|c 这种形式的字符串,我要把它切分成3个字符串,用三个span显示,应该怎么写?

要查出tags字段对应的哪些值,怎么写?

控制器:

<code>  $str='abc|efg|hij';
  $arr=explode('|',$str);
  $this->assign('arr',$arr);
</code>
Copy after login

视图:

<code> <foreach name="arr" item="var">
        <span>{$var}</span>
    </foreach>
    </code>
Copy after login

楼上写的完全正确 只是我喜欢用 foreach 比较简单, volist 中很多属性都没用过

先要在控制器处理一下吧

<code>foreach($list as $k=>$v){
    $v['tags'] = explode("|",$v['tags']);
}</code>
Copy after login
<code><volist name="vo.tags" id="sub">
<span class="badge">{$sub}</span>
</volist></code>
Copy after login

$str='abc|efg|hij';
$arr=explode('|',$str);
$this->assign('arr',$arr);

view中:


{$sub}

数组中有几个值就生成几个span

我的意思,是说,一条数据表记录,有一个字段,叫tags,tags的内容是a|b|c|, 怎么把tags分成三个span显示在页面上?
有没有路过的高手指点下?
究竟应该怎么写?
