</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; "><strong>三、修改dedecms程序</strong></p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
进入dedecms的后台，在“模板管理”中的“标签源码管理”，找到arclist.lib.php ，点击“编辑”，找到</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
“$titlelen = AttDef($titlelen,30); ”条语句，把其中的30改为60或者更大的数值即可。当然你也可以在</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
includetaglib 这个目录中找到arclist.lib.php，然后同样的方法修改好，再传到你的空间。</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; "><br/>
修改完数据库后，发布文章标题长度应该没问题了，但是如果更改文章后标题又变成80字节了，这是因为</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
dedeactionarticle_eidt_action.php对标题进行了限制</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; "><br/>
打开dedeactionarticle_eidt_action.php 找到44行 $title = cn_substr($title,80); 删除此行代码， 或者修改</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
为</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
</p><div class="msgheader" style="margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; "><div class="right"><span style="text-decoration:underline;">复制代码</span></div><p>
代码如下:</p></div><div class="msgborder" id="phpcode6" style="margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; ">
$title = cn_substr($title,200);</div><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
还需要在phpmyadmin里执行下面的代码</p><p style="margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; ">
</p><div class="msgheader" style="margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; "><div class="right"><span style="text-decoration:underline;">复制代码</span></div><p>
代码如下:</p></div><div class="msgborder" id="phpcode7" style="margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; ">
