if(!isset($_GLOBAL_NEWS_QIKAN_TYPES)){
$_GLOBAL_NEWS_QIKAN_TYPES=array('1'=>'卷首语',
'2'=>'管理层专栏',
        '3'=>'研发?技术',
'4'=>'市场速递',
'5'=>'小蜜蜂家园',
        '6'=>'推荐?分享',
'7'=>'旅行?生活'
);
}



$global_news_type_inc =array();
$global_news_type_inc['1']='行业新闻';
$global_news_type_inc['2']='期刊';
?>
以上是2个数组的,然后在当我选择期刊的时候,出现上面那数组的下拉框?求大神指点,用php哦


回复讨论(解决方案)

js控制了,先把上面那个select框设置display:none 属性。然后当第二个select框选择期刊时设置它为display:block 就可以了

同意楼上说法,在select中添加onclick,调用js函数进行标签的属性处理,显示设置disply:block否则dispau:none

这用PHP真没法解决,JS可以动态处理页面,而PHP没办法,而且JS也很容易,两三句就搞定了...
楼上方法正解~
都是新手,受教了!

网上搜一下,JS多级联动,有很多例子。。。
