ThinkPHP的View视图里怎么切分一个字符串
<code><span class="badge">{$vo.tags}</span> </code>
{$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?
显示一条数据库记录的tags字段,应该怎么写呢?
回复内容:
<code><span class="badge">{$vo.tags}</span> </code>

控制器:
<code> $str='abc|efg|hij'; $arr=explode('|',$str); $this->assign('arr',$arr); </code>
视图:
<code> <foreach name="arr" item="var"> <span>{$var}</span> </foreach> </code>
楼上写的完全正确 只是我喜欢用 foreach 比较简单, volist 中很多属性都没用过
先要在控制器处理一下吧
<code>foreach($list as $k=>$v){ $v['tags'] = explode("|",$v['tags']); }</code>
<code><volist name="vo.tags" id="sub"> <span class="badge">{$sub}</span> </volist></code>
$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?
