[field:senddate runphp='yes']

$ntime = time();

$oneday = 3600 * 24;

if(($ntime - @me)<$oneday)

@me = "<font color='red'>(new)</font>";

else @me = "";

[/field:senddate]

{dede:field name=typeid runphp="yes"}

global $dsql;

$sql = "SELECT id From `dede_arctype` WHERE reid='@me' And ishidden<>1 order by sortrank asc limit 0, 100 ";

    $row = $dsql->GetOne($sql); 

if(@me=is_array($row))

@me="有子栏目";

else @me = "没子栏目";
