JS跳转

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 ("/\[[^\]]*\]|\[\/+\]/i",'',preg_replace("/\\d+\[\/attach\]/i",'',$message));
调用单个数据
$a = DB::result(DB::query("SELECT qi FROM ".DB::table('abc')." WHERE id = '1'"));
调用统计数据
$a = DB::result(DB::query("SELECT count(*) FROM ".DB::table('abc')." WHERE id = '1'"));
单数据表调用
$perpage = 20;
$curpage = empty ( $_GET['page'] ) ? 1 : intval ( $_GET['page'] );
$start = ($curpage-1)*$perpage;
$askcount = DB::result(DB::query("SELECT COUNT(*) FROM ".DB::table('forum_thread')." WHERE fid = '2' AND authorid > 1"));
//$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, "这里填写跳转地址");
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'"));}-->
<img src="$tupianfm"><br>$value
<!--{/loop}-->
取数据表中符合条件的第一条数据
$app=array();
$app=DB::fetch_first("select * from ".DB::table('abc')." where id='{$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 ("/\[[^\]]*\]|\[\/+\]/i",'',preg_replace("/\\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('abc', $setarr, 1);
$query = DB::query("UPDATE ".DB::table('abc')." SET stickreply='1' WHERE tid='$tid'");
$query = DB::query("DELETE FROM ".DB::table('abc')." WHERE pid='$pid'");
showmessage('成功的提示信息', "跳转地址");
}
表单提交
<form action="do.php" method="post" autocomplete="off">
<input type="hidden" value="{FORMHASH}" name="formhash" />
最低奖金：<input name="qi" type="text" value="" />
最高奖金：<input name="end" type="text" value="" />
<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, -1); $cover = DB::result(DB::query("SELECT attachment FROM ".DB::table('forum_attachment_'.$biaoid.'')." WHERE tid = '$value'"));}
数据库循环嵌套调用
{eval $slides = DB::fetch_all("SELECT * FROM ".DB::table('a')." WHERE `uid`= $_G ORDER BY `id` DESC");}
{loop $slides $slide}
$slide
{/loop}

$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="do.php?id='+jq(this).attr('dataid')+'" height="350" width="1070" frameborder="0" scrolling="no"></iframe>';

DISCUZ JSON数据解析获取
$str = 'a:2:{s:8:\"sitename\";s:8:\"学院\";s:3:\"pic\";s:12:\"banbanso.jpg\";}';
$newstr = str_replace("\\","",$str);
$data = unserialize($newstr);
