在WordPress仪表盘的“概况（Right Now）”小工具会显示文章、分类、评论等数据，今天倡萌就分享下在WordPress仪表盘“概况”小工具显示自定义文章类型的数据的方法。

将下面的代码添加到当前主题的 functions.php 文件即可：

//在WordPress仪表盘“概况”显示自定义文章类型数据（在WP 3.5.2 测试通过）
function wph_right_now_content_table_end() {
	$args = array(
		'public' => true ,
		'_builtin' => false
	);
	$output = 'object';
	$operator = 'and';
	$post_types = get_post_types( $args , $output , $operator );
	foreach( $post_types as $post_type ) {
		$num_posts = wp_count_posts( $post_type->name );
		$num = number_format_i18n( $num_posts->publish );
		$text = _n( $post_type->labels->singular_name, $post_type->labels->name , intval( $num_posts->publish ) );
		if ( current_user_can( 'edit_posts' ) ) {
			$num = "<a href='edit.php?post_type=$post_type->name'>$num</a>";
			$text = "<a href='edit.php?post_type=$post_type->name'>$text</a>";
		}
		echo '<tr><td class="first num b b-' . $post_type->name . '">' . $num . '</td>';
		echo '<td class="text t ' . $post_type->name . '">' . $text . '</td></tr>';
	}
	$taxonomies = get_taxonomies( $args , $output , $operator ); 
	foreach( $taxonomies as $taxonomy ) {
		$num_terms  = wp_count_terms( $taxonomy->name );
		$num = number_format_i18n( $num_terms );
		$text = _n( $taxonomy->labels->singular_name, $taxonomy->labels->name , intval( $num_terms ));
		if ( current_user_can( 'manage_categories' ) ) {
			$num = "<a href='edit-tags.php?taxonomy=$taxonomy->name'>$num</a>";
			$text = "<a href='edit-tags.php?taxonomy=$taxonomy->name'>$text</a>";
		}
		echo '<tr><td class="first b b-' . $taxonomy->name . '">' . $num . '</td>';
		echo '<td class="t ' . $taxonomy->name . '">' . $text . '</td></tr>';
	}
}
add_action( 'right_now_content_table_end' , 'wph_right_now_content_table_end' );
