WordPress主题中添加文章列表页页码导航的PHP代码实例

WordPress 默认给主题开发者的建议是在文章列表底部提供上下页按钮，所以没有提供直接用在文章列表下的分页导航的函数。这里我提供一个比较完善的分页导航函数。

然后在需要使用分页导航的地方添加下边的代码：
<div>
<div>
<div id="highlighter_503085">

?
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>
1</div>
</td>
<td>
<div>
<div>
<code><?php </code><code>if</code><code>( function_exists( </code><code>'Bing_get_pagenavi'</code> <code>) ) Bing_get_pagenavi(); ?></code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
