HomeBackend DevelopmentPHP TutorialWordPress开发中用于获取近期文章的PHP函数使用解析_PHP

wp_get_recent_posts 函数在 WordPress 中是一个可以获取近期文章数组的函数,相较于其他的文章获取方式, wp_get_recent_posts 返回的将是一个数组而不是对象,所以在使用中对于一些新手或者是懒人,可能会更方便一些,下面我们就实例讲解一下这个函数。

描述
wp_get_recent_posts
英文解释很短,就不贴了,
中文大概意思是:获取最新文章的函数。
实际上这是一个 get_posts函数的再使用。
描述的再好也木用,下面看使用。

使用/用法

 <&#63;php 
  wp_get_recent_posts( $args ) 
 &#63;>

参数默认值

 <&#63;php $args = array(
//获取的文章数量
  'numberposts' => 10,
//从第几篇开始获取
  'offset' => 0,
//分类的ID,如果不设置则显示全部分类
  'category' => 0,
//排序规则 (注1,下详)
  'orderby' => 'post_date',
//升、降序排列
  'order' => 'DESC',
//包括的文章ID
  'include' => ,
//排除的文章ID
  'exclude' => ,
//自定义字段名称
  'meta_key' => ,
//自定义字段的值,配合上一个参数,来选择显示符合自定义字段数值的文章。
  'meta_value' =>,
//文章类型:文章或页面
  'post_type' => 'post',
//文章状态:草稿、已发布、隐藏文章等....
  'post_status' => 'draft, publish, future, pending, private',
//这个木研究
  'suppress_filters' => true ); 
&#63;>

实例
因为跟 get_posts 的使用方法实在是很相似,
所以就不给什么高深的例子了,简单的给一个官方的例子。

<h2 id="Recent-Posts">Recent Posts</h2>
<ul>
<&#63;php
 //获取最新文章
 $recent_posts = wp_get_recent_posts();
 //遍历出每一篇文章。
 foreach( $recent_posts as $recent ){
 echo '<li><a href="' . get_permalink($recent["ID"]) . '" title="Look '.esc_attr($recent["post_title"]).'" >' .  $recent["post_title"].'</a> </li> ';
 }
&#63;>
</ul>

总结
注意:因为wp_get_recent_posts函数的返回值是一个数组,
setup_postdata 函数理论上只能接受对象类型的变量,
所以按照官方文档的解释是不能使用setup_postdata函数,装载到循环中使用的。
因为用的不多,所以我也就没有去试,有兴趣的同学可以试一试看能否成功。
所以说,如果使用 setup_postdata 函数的话,
wp_get_recent_posts 函数不如 get_posts 函数使用起来方便。

注:
‘author' —— 按作者数值编号排序
‘category' —— 按类别数值编号排序
‘content' —— 按内容排序
‘date' —— 按创建日期排序
‘ID' —— 按文章编号排序
‘menu_order' —— 按菜单顺序排序。仅页面可用。
‘mime_type' —— 按MIME类型排序。仅附件可用。
‘modified' —— 按最后修改时间排序。
‘name' —— 按存根排序。
‘parent' —— 按父级ID排序
‘password' —— 按密码排序
‘rand' —— 任意排序结果
‘status' —— 按状态排序
