Detailed explanation of the use case of volist tag in thinkphp
This time I will bring you a detailed explanation of the use case of the volist tag in thinkphp. What are the precautions when using the volist tag in thinkphp. The following is a practical case, let's take a look.
Attributes:
name (required): data template variable to be output
id (required): loop variable
offset (optional): the offset of the data to be output
length (optional): the length of the output data
key (optional): the key variable of the loop, the default value is i
mod (optional): modulo the key value, the default is 2
empty (optional): the string displayed if the data is empty
The result returned by the select method of the usual model is a two-dimensional array, which can be output directly using the volist tag.
$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">{$vo.name}</eq>
</volist>mod starts counting from 0, here the mod loop count is 0,1
The Mod attribute is also used to control the line wrapping of certain records, for example:
<volist name="list" id="vo" mod="5" >
{$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 will be used by default Variable i, for example:
<volist name="list" id="vo" >
{$i}.{$vo.name}
</volist><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>Effect
