有关参数的完整解释，请参见get_posts()和WP_Query对象。

参数：

$args

(array) (可选) 查询条件数组

默认值: array

$output

(string) (可选) 常量对象, ARRAY_A

默认值: ARRAY_A

示例：

使用wp_get_recent_posts()函数列出最近10篇文章

<h2>Recent Posts</h2>
<ul>
<?php
	$recent_posts = wp_get_recent_posts();
	foreach( $recent_posts as $recent ){
		echo '<li><a href="' . get_permalink($recent["ID"]) . '">' .   $recent["post_title"].'</a> </li> ';
	}
?>
</ul>

如果您想限定最近的文章，您必须在函数参数中输入数字，如下例所示：

<h2>Recent Posts</h2>
<ul>
<?php
	$args = array( 'numberposts' => '5' );
	$recent_posts = wp_get_recent_posts( $args );
	foreach( $recent_posts as $recent ){
		echo '<li><a href="' . get_permalink($recent["ID"]) . '">' .   $recent["post_title"].'</a> </li> ';
	}
?>
</ul>

要排除具有特定文章形式的文章，可以使用类“Reference/WP”“Query”“Taxonomy”“参数，如下例所示，它排除具有“aside”和“image”格式的所有帖子：

<h2>Recent Posts</h2>
<ul>
<?php
	$args = array( 'numberposts' => '5', 'tax_query' => array(
			array(
				'taxonomy' => 'post_format',
				'field' => 'slug',
				'terms' => 'post-format-aside',
				'operator' => 'NOT IN'
			), 
			array(
				'taxonomy' => 'post_format',
				'field' => 'slug',
				'terms' => 'post-format-image',
 				'operator' => 'NOT IN'
			)
	) );
	$recent_posts = wp_get_recent_posts( $args );
	foreach( $recent_posts as $recent ){
		echo '<li><a href="' . get_permalink($recent["ID"]) . '">' .   ( __($recent["post_title"])).'</a> </li> ';
	}
?>
</ul>
