1、自动向 WordPress 编辑器插入文本
编辑当前主题目录的 functions.php 文件，并粘贴以下代码：

复制代码 代码如下:
add_filter( http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachdefault_contenthttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach, http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachmy_editor_contenthttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach );
function my_editor_content( $content ) {
$content = "芒果小站 - 这里不卖芒果，请另寻他处购买。";
return $content;
}
?>

2、获取 WordPress 注册用户数量
通过简单的 SQL 语句，即可方便获得 WordPress 注册用户的数量：

复制代码 代码如下:
$users = $wpdb->get_var("SELECT COUNT(ID) FROM $wpdb->users");
echo "总共有 ".$users." 位注册用户";

3、根据指定自定义字段获取 WordPress 文章
在 query_posts() 函数中传入自定义字段参数，即可获取对应文章列表：

复制代码 代码如下:




参数中 meta_key 是索要获取自定义字段名称，meta_value 是自定义字段取值。

4、获取某个时间段的 WordPress 文章
编辑 index.php 文件，只需在循环体之前，添加以下代码即可。当然需要根据需要更换时间段的设置：

复制代码 代码如下:
function filter_where($where = http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachhttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach) {
$where .= " AND post_date >= http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach2009-01-01http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach AND post_date <= http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach2010-01-01http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach";
return $where;
}
add_filter(http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachposts_wherehttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach, http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachfilter_wherehttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach);
query_posts($query_string);
?>

5、为某个 WordPress 标签生成 RSS 订阅源
如你所见，标签可以通过逗号分割，这样也可以获取多个标签的 RSS Feed 源：

6、防止缓存 WordPress 样式文件
通过服务器端设置以防止客户端读取缓存文件：

复制代码 代码如下:
" >

7、用户统计文章字数的 WordPress 函数
在当前主题的 functions.php 文件中粘贴以下代码：

复制代码 代码如下:
function wcount(){
ob_start();
the_content();
$content = ob_get_clean();
return sizeof(explode(” “, $content));
}

函数调用方法：



8、禁止 WordPress 自动保存文章
要禁用 WordPress 的自动保存功能，请编辑 functions.php 文件并添加以下代码：

复制代码 代码如下:
function disableAutoSave(){
wp_deregister_script(http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachautosavehttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach);
}
add_action( http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachwp_print_scriptshttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach, http://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attachdisableAutoSavehttp://www.moke8.com/data/attachment/portal/201705/03/081107zdgkq8cmmccmoq3c.attach );
