1、使用PHPMYADMIN 修改 MYSQL数据结构
CODE: ALTER TABLE `dede_archives` CHANGE `title` `title` VARCHAR( 250 ) [Copy to clipboard]
2、打开/dede/action_article_save.php
找到39行 CODE: $title = cn_substr($title,60); [Copy to clipboard]
修改为 CODE: $title = cn_substr($title,250) [Copy to clipboard] ;
3、打开/dede/action_archives_edit_save.php
找到32行 CODE: $title = cn_substr($title,60); [Copy to clipboard]
修改为 CODE: $title = cn_substr($title,250) [Copy to clipboard] ;
OK，这样你的文章标题支持125个中文字符了！
