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>
{$vo.id}
{$vo.name}
</volist>

Output even records

<volist>
<eq>{$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>
{$vo.name}
<eq><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>
{$k}.{$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>
{$i}.{$vo.name}
</volist>

Comprehensive case:

<volist>
<p>
<input>checked="checked"><label></label><span>{sh:$vo.name} 电话({sh:$vo.tel})</span>
</p>
{sh:$mod}
<eq><br></eq>
</volist>
