Usually the result returned by the select method of the model is a two-dimensional array, and the volist tag can be used directly for output.
$User = M('User'); $list = $User->select(); $this->assign('list',$list); <volist name="list" id="vo"> {$vo.id} {$vo.name} </volist>
Output even records
<volist name="list" id="vo" mod="2" > <eq name="mod" value="1">{$vo.name}</eq> </volist>
mod starts counting from 0, here the mod loops The count is 0,1
Mod attribute is also used to control the line wrapping of certain records, for example:
<volist name="list" id="vo" mod="5" > {$vo.name} <eq name="mod" value="4"><br/></eq> </volist>
mod loop count, 0,1 ,2,3,4 wrap when the value is 4. That is, 5 pieces of data are changed to one row.
Output loop variable
<volist name="list" id="vo" key="k" > {$k}.{$vo.name} </volist>
The loop variable starts from 1 1, 2, 3, 4
If the key attribute is not specified, the loop variable i is used by default, for example:
<volist name="list" id="vo" > {$i}.{$vo.name} </volist>
Comprehensive case:
<volist name="agentData" id="vo" mod="3" key="k" empty="暂时没有数据"> <p style="display:inline-block;width:280px;margin:3px;"> <input type="radio" class="regular-radio" value="{sh:$vo.agent_id}" name="agent_id" id="agent_{sh:$k}" <eq name="k" value="1">checked="checked"</eq>><label for="agent_{sh:$k}"></label><span style="display:inline-block;padding:0px 0px 5px 5px;">{sh:$vo.name} 电话({sh:$vo.tel})</span> </p> {sh:$mod} <eq name="mod" value="2"><br/></eq> </volist>
