WordPress文章添加阅读次数统计,会用到wp-postviews或者wp-postviews-plus插件,本着插件能不用就不用的原则,在这里介绍一个不用插件实现文章阅读次数显示的方法.
将下面代码加到主题functions模版文件中:
//postviews
function get_post_views ($post_id) {
$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');
$count = '0';
}
echo number_format_i18n($count);
}
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, $count + 1);
}
}
}
add_action('get_header', 'set_post_views');
将调用显示阅读次数代码加到single模版适当的位置:
<?php get_post_views($post -> ID); ?> views
调用显示阅读次数代码也可以加到其它模版文件的适当位置.
