完美去除discuz x2底部版权和去掉头部

完美去除discuz x2底部版权和去掉头部“powered by discuz!”（慎用）discuz x2自发布以来很多网友希望能够去掉discuz版权，其实做二次开发代码也要考虑discuz既然开放给大家使用了，大家也厚道一点，起码保留一下版权，这是尊重知识产权的基本原则吧。

站在网友的立场上本人放出详细去discuz版权的教程，也可以说是完美去版权了。

最后提醒大家“慎用！”如有网友侵权引起纠纷，与本人无关，我只是站在技术角度去二次开发。

谢谢配合！一、去除头部版权在原来的discuz X2版本中，标题中去掉“Powered by Discuz!”版权标识很容易，只需要修改模板文件的头部公用文件，将“Powered by Discuz!”这一行字去掉即可。

但是discuz X2 似乎对这点有所防备，把-Powered by Discuz!中的-放在了变量里，所以删除后，标题一句话结束后会有一个小-尾巴，对搜索引擎很不友好，所以也有一个好的办法完美解决，即：打开\template\default\common\header_common.htm文件，找到<title><!–{if !empty($navtitle)}–>$navtitle –<!–{/if}–><!–{if empty($nobbname)}–> $_G['setting']['bbname']-<!–{/if}–>Powered by Discuz!</title>将其中的“Powered By Discuz!”字串改为“{lang secondtitle}”。

再打开source/language/lang_template.php。

在变量的最后，也就是整个数组的目录后按以前的格式，加上“‘secondtitle’=> ‘你的论坛名称!”,”。

更新缓存即可。

二、去除底部的版本打开template\default\common，找到footer.htm文件，用deamweaver打开，点击编辑，再点击查找和替换powerd by，知道相应的位置把底部版权的相应内容改了就ok了，注意修改下面红色标记部分</div><!--{if empty($topic) || ($topic[usefooter])}--><!--{eval $focusid = getfocus_rand($_G[basescript]);}--><!--{if $focusid !== null}--><!--{eval $focus = $_G['cache']['focus']['data'][$focusid];}--><div class="focus" id="sitefocus"><div class="bm"><div class="bm_h cl"><a href="javascript:;" onclick="setcookie('nofocus_$focusid', 1,$_G['cache']['focus']['cookie']*3600);$('sitefocus').style.display='none'" class="y"title="{lang close}">{lang close}</a><h2><!--{if$_G['cache']['focus']['title']}-->{$_G['cache']['focus']['title']}<!--{else}-->{langfocus_hottopics}<!--{/if}--></h2></div><div class="bm_c"><dl class="xld cl bbda"><dt><a href="{$focus['url']}" class="xi2"target="_blank">$focus['subject']</a></dt><!--{if $focus[image]}--><dd class="m"><a href="{$focus['url']}" target="_blank"><imgsrc="{$focus['image']}" alt="$focus['subject']" /></a></dd><!--{/if}--><dd>$focus['summary']</dd></dl><p class="ptn hm"><a href="{$focus['url']}" class="xi2" target="_blank">{lang focus_show} &raquo;</a></p></div></div></div><!--{/if}--><!--{ad/footerbanner/wp a_f/1}--><!--{ad/footerbanner/wpa_f/2}--><!--{ad/footerbanner/wp a_f/3}--><!--{ad/float/a_fl/1}--><!--{ad/float/a_fr/2}--><!--{ad/couplebanner/a_fl a_cb/1}--><!--{ad/couplebanner/a_fr a_cb/2}--><!--{ad/cornerbanner/a_cn}--><!--{hook/global_footer}--><div id="ft" class="wp cl"><div id="flk" class="y"><p><!--{loop $_G['setting']['footernavs'] $nav}--><!--{if $nav['available'] &&($nav['type'] && (!$nav['level'] || ($nav['lev el'] == 1 && $_G['uid']) || ($nav['level'] == 2 && $_G['adminid'] > 0) || ($nav['level'] == 3 && $_G['adminid'] == 1)) || !$nav['type'] && ($nav['id'] == 'stat' && $_G['group']['allowstatdata'] || $nav['id'] == 'report' && $_G['uid'] || $nav['id'] == 'archiver' || $nav['id'] == 'mobile'))}--><!--{if $nav['id'] == 'mobile' && $_G['setting']['mobile']['allowmobile'] != 1}--><!--{eval continue;}--><!--{/if}-->$nav[code]<spanclass="pipe">|</span><!--{/if}--><!--{/loop}--><strong><a href="$_G['sett ing']['siteurl']"target="_blank">$_G['setting']['sitename']</a></strong><!--{if $_G['setting']['icp']}-->( <a href="/" target="_blank">$_G['setting']['icp']</a> )<!--{/if}--><!--{hook/global_footerlink}--><!--{if $_G['setting']['statcode']}-->$_G['setting']['statcode']<!--{/if}--></p><p class="xs0">{lang time_now}<span id="debuginfo"><!--{if debuginfo()}-->, Processed in $_G[debuginfo][time] second(s),$_G[debuginfo][queries] queries<!--{if $_G['gzipcompress']}-->, Gzip On<!--{/if}--><!--{if $_G['memory']}-->,<!--{echo ucwords($_G['memory'])}--> On<!--{/if}-->.<!--{/if}--></span></p></div><div id="frt"><p>Powered by <strong><a href="/" target="_blank">百度</a></strong> <em>$_G['setting']['version']</em><!--{if !empty($_G['setting']['boardlice nsed'])}--> <a href= target="_blank">Licensed</a><!--{/if}--></p><p class="xs0">&copy;
