早上改了一下有玩社区的标题字数限制，还专门写了篇文章来做笔记，现在想了想，以后要改的东西还有很多，如果每改一次就写一篇，很明显效率不高，也不方便以后查阅。
所以决定用这篇文章来持续记录改过的文件，也方便给有需要的人进行参考。下面所有的修改都是基于 Discuz 3.4 版本，如果是以前的版本，可能代码位置不一样，只能以本文作为参考。
因为仅仅是做个记录，所以不会写得很详细，如果小伙伴看不懂的，欢迎下方留言，我会认真回复你的。

2、限制发帖标题字数
文件路径 /static/js/forum_post.js
if(($('postsubmit').name != 'replysubmit' && !($('postsubmit').name == 'editsubmit' && !isfirstpost) && theform.subject.value == "") || !sortid && !special && trim(message) == "") {
showError('抱歉，您尚未输入标题或内容');
return false;
} else if(mb_strlen(theform.subject.value) > 80) {
showError('您的标题超过 80 个字符的限制');
return false;
}下面插入
else if(mb_strlen(theform.subject.value) < 20 && mb_strlen(theform.subject.value) > 0) {
showError('您的标题不足 20 个字符的限制');
return false;
}2019.07.30
1、去除标题 Powered by Discuz!
文件路径 /template/default/common/header_common.htm
<title><!--{if !empty($navtitle)}-->$navtitle - <!--{/if}--><!--{if empty($nobbname)}--> $_G['setting']['bbname'] - <!--{/if}--> Powered by Discuz!</title>改为
<title><!--{if !empty($navtitle)}-->$navtitle - <!--{/if}--><!--{if empty($nobbname)}--> $_G['setting']['bbname']<!--{/if}--></title>2019.07.16
