帝国cms随机调用N个终极栏目
帝国cms随机调用N个终极栏目方法一:(适用于栏目非常多的情况下,效率比较好)
<?php
function IslastClassid(){
global $class_r;
foreach ($class_r as $k => $v) {
if ($v['islast'] == 1) {
$all[]= $v['classid'];
}
}
$rand_key = array_rand($all , 5);//随机取5个
foreach ($rand_key as $k => $v) {
$classall.= $v.',';
}
$classall = trim($classall , ',');
$classall = $classall ? $classall : 0 ;
return $classall;
}
$class_sql=$empire->query('select * from '.$dbtbpre.'enewsclass where classid in ('.IslastClassid().') order by myorder');
while($class_row=$empire->fetch($class_sql)){
$classurl=sys_ReturnBqClassUrl($class_r[$class_row['classid']]); //栏目链接地址
?>
<li><a href="<?=$classurl?>"><?=$class_row['classname']?></a></li>
<?
}
?>
方法二:(栏目不多的情况下可以使用)<?php
$class_sql=$empire->query('select * from '.$dbtbpre.'enewsclass where islast=1 order by RAND()LIMIT 5');
while($class_row=$empire->fetch($class_sql)){
$classurl=sys_ReturnBqClassUrl($class_r[$class_row['classid']]); //栏目链接地址
?>
<li><a href="<?=$classurl?>"><?=$class_row['classname']?></a></li>
<?
}
?>
