wordpress修改固定链接后301重定向的方法
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>以前小站的固定链接好不人性化,结构是/%year%/%monthnum%/%postname%/,这样看起来又不直观又长的,今天做了一个301重定向,然后修改了新的固定链接,现在的固定链接格式是/%postname%.html,这样看起来短了好多,也直观了好多,<br>
不过小站已经被搜索引擎收录了好多,以前的地址都无法访问了,所以要做好301重定向,跳转到新的固定链接所生成的地址中去.要不然都是404就悲剧了.下面贴出解决办法</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<div 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; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode1" 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; font-family: tahoma, arial, "Microsoft YaHei";'>

将我的$rewrite_config['oldstructure'] = “/%year%/%monthnum%/%postname%/”后面的/%year%/%monthnum%/%postname%/修改成你自己的旧的固定链接格式,然后将这段代码加入到主题的function.php中,然后设置成新的固定链接格式就搞定了.</p>
