JS更换class的名称
document.getElementById('idname').className='a';
document.getElementById('idname').style.display='block';
document.getElementById("idname").style.marginTop="30px";

批量替换超链接：href="[^"]*"

过滤DZ代码：
preg_replace ("/\[[a-z][^\]]*\]|\[\/[a-z]+\]/i",'',preg_replace("/\[attach\]\d+\[\/attach\]/i",'',$message));

………………………………………………………………………………………………………………………………………………………………

调用单个数据
$qishi = DB::result(DB::query("SELECT qi FROM ".DB::table('jiangchi')." WHERE id = '1'"));

调用统计数据
$qishi = DB::result(DB::query("SELECT count(*) FROM ".DB::table('jiangchi')." WHERE id = '1'"));

单数据表调用
$perpage = 20;
$curpage = empty ( $_GET['page'] ) ? 1 : intval ( $_GET['page'] );
$start = ($curpage-1)*$perpage;
$askcount = DB::result(DB::query("SELECT COUNT(*) FROM ".DB::table('forum_thread')." WHERE fid = '2' AND authorid > 1 AND FROM_UNIXTIME(dateline, '%Y%m%d') = '$jintian'"));
//$asklist
$asklist = array();
if ($askcount) {
	$query = DB::query("SELECT * FROM ".DB::table('forum_thread')." WHERE fid = '2' AND displayorder > -1 ORDER BY tid ASC LIMIT $start,$perpage");
	while ($value = DB::fetch($query)) {
		$asklist[] = $value;
	}
}
$multi = multi($askcount, $perpage, $curpage, "portal.php?mod=topic&topic=ask");


多数据表调用
$perpage = 40;
$curpage = empty ( $_GET['page'] ) ? 1 : intval ( $_GET['page'] );
$start = ($curpage-1)*$perpage;
$acount = DB::result(DB::query("SELECT count(*) FROM ".DB::table('forum_forum')." b LEFT JOIN ".DB::table('forum_forumfield')." bf ON bf.fid=b.fid WHERE b.type='sub' AND b.status = 3 AND bf.icon != ''"));
//$alist
$alist = array();
if ($acount) {
	$query = DB::query("SELECT bf.*, b.* FROM ".DB::table('forum_forum')." b LEFT JOIN ".DB::table('forum_forumfield')." bf ON bf.fid=b.fid WHERE b.type='sub' AND b.status = 3 AND bf.icon != '' ORDER BY bf.shoplevel DESC, b.commoncredits DESC, bf.fid DESC LIMIT $start,$perpage");
	while ($value = DB::fetch($query)) {
		$alist[] = $value;
	}
}
$multi = multi($acount, $perpage, $curpage, "这里填写跳转地址");

前台数据显示
<!--{loop $alist $key $value}-->
<!--{eval $tupianfm = DB::result(DB::query("SELECT attachment FROM ".DB::table('forum_threadimage')." WHERE tid = '$value[tid]'"));}-->
$value[authorid]
<!--{/loop}-->

取数据表中符合条件的第一条数据
$app=array();
$app=DB::fetch_first("select * from ".DB::table('home_diy_center')." where id='{$id}'");

人性化时间戳
<!--{echo dgmdate(这里填写时间参数, 'u', '9999', getglobal('setting/dateformat'))}-->
<!--{echo date("Y-m/d H:i:s",这里填写时间参数)}-->

截取字符字数
<!--{echo cutstr(这里填写参数,40)}-->

过滤DISCUZ代码
preg_replace ("/\[[a-z][^\]]*\]|\[\/[a-z]+\]/i",'',preg_replace("/\[attach\]\d+\[\/attach\]/i",'',$message));

写入数据库
if(submitcheck('tijiao')) {
	$setarr = array(
		'tid' => $_GET['topicid'],
		'name' => $_POST['name'],
		'position' => $_GET['position'],
		'dateline' => $_G['timestamp'],
	);
	DB::insert('forum_poststick', $setarr, 1);
	$query = DB::query("UPDATE ".DB::table('forum_thread')." SET stickreply='1' 
		WHERE tid='$tid'");
	$query = DB::query("DELETE FROM ".DB::table('forum_post')." WHERE pid='$pid'");
	showmessage('成功的提示信息', "forum.php?mod=viewthread&tid=$tid");
}

表单提交：
<form action="do.php?op=jiangchi&con=yes" method="post" autocomplete="off">
	<input type="hidden" value="{FORMHASH}" name="formhash" />
	最低奖金：<input name="qi" type="text" value="$qishi" />　
	最高奖金：<input name="end" type="text" value="$zhzh" />　　
	<button value="true" name="tijiao" type="submit">提交设置</button>
	<input type="hidden" name="tijiao" value="true" />
</form>

以下两个时间格式是对等关系
date("Ymd",time());  20150212
FROM_UNIXTIME(dateline, '%Y%m%d')
前者用于PHP，后者用于数据库调用的字段的格式化

调用图片附件
<!--{eval $biaoid = substr($value[tid], -1); $cover = DB::result(DB::query("SELECT attachment FROM ".DB::table('forum_attachment_'.$biaoid.'')." WHERE tid = '$value[tid]'"));}-->

数据库循环嵌套调用
<!--{eval $slides = DB::fetch_all("SELECT * FROM ".DB::table('a')." WHERE `uid`= $_G[uid] ORDER BY `id` DESC");}-->
<!--{loop $slides $slide}-->
$slide[name]
<!--{/loop}-->

ucenter无法登录：
打开uc_server/model/admin.php
找到第22行的
$this->cookie_status = 0;
改成
$this->cookie_status = isset($_COOKIE['sid']) ? 1 : 0;

无刷新切换li标签并且同时加载框架页面：
<script type="text/javascript"> 
var jq = jQuery.noConflict();
jq(function(){ 
jq("#changemenu>li").mouseover(function(){ 
jq("#changemenu>li").each(function(i){ 
jq(this).removeClass("current"); 
}); 
jq(this).addClass("current"); 
document.getElementById("changenr").innerHTML='<iframe src="chart.php?op=index&id='+jq(this).attr('dataid')+'" height="350" width="1070" frameborder="0" scrolling="no"></iframe>';
}).mouseout(function(){ 
jq(this).addClass("current"); 
}); 
});
</script>
<ul id=“changemenu”>
   <li class=“current” dataid=“1”></li>
   <li dataid=“2”></li>
</ul>
<div id=“changenr”></div>
