WP-PostViews续集：精简版代码

of.gs在前段时间发布了一段WP-Postviews的精简版，因为大多数的站长只需要它的统计和浏览数，那么我们实现这两个功能就好了。zww大神将其做出修改，可尝试在functions.php中添加以下代码：

//////// postviews - byhttp://of.gs/un-plugin-post-views.html, modify by zwwooooo|zww.me
function custom_the_views($post_id, $echo=true, $views=' views') {
	$count_key = 'views';
	$count = get_post_meta($post_id, $count_key, true);
	if ($count == '') {
		delete_post_meta($post_id, $count_key);
		add_post_meta($post_id, $count_key, '0');
		$count = '0';
	}
	if ($echo)
		echo number_format_i18n($count) . $views;
	else
		return number_format_i18n($count) . $views;
}
function set_post_views() {
	global $post;
	$post_id = $post->ID;
	$count_key = 'views';
	$count = get_post_meta($post_id, $count_key, true);
	if (is_single() || is_page()) {
		if ($count == '') {
			delete_post_meta($post_id, $count_key);
			add_post_meta($post_id, $count_key, '0');
		} else {
			update_post_meta($post_id, $count_key, $count + 1);
		}
	}
}
add_action('get_header', 'set_post_views');

参数使用说明：

1. $post_id: 文章ID，一般填 $post->ID

2. $echo: true/false，显示/获取浏览数（默认是显示-true）

3. $views: 浏览数单位（默认是：空格+views）

一般调用方法：

<?php if ( function_exists('custom_the_views') ) custom_the_views($post->ID); ?>
