wordpress文章浏览量的实现方法
我们在网上找到很多使用插件来实现,但个人学喜欢插件怕不安全或代码太多了,后来找到一个朋友写的一段代码,wordpress不用插件来实现功能方法.
第一种, 找到functions模板,加入以下代码:
function getPostViews( $postID ){ $count_key = ‘post_views_count’; $count = get_post_meta( $postID , $count_key , true); if ( $count ==]){ delete_post_meta( $postID , $count_key ); add_post_meta( $postID , $count_key , ’0′); return [0 View]; } return $count .’ Views’; } function setPostViews( $postID ) { $count_key = ‘post_views_count’; $count = get_post_meta( $postID , $count_key , true); if ( $count ==]){ $count = 0; delete_post_meta( $postID , $count_key ); add_post_meta( $postID , $count_key , ’0′); } else { $count ++; update_post_meta( $postID , $count_key , $count ); } }然后将下面代码加到主题single模版主循环的中,代码如下:
<?php setPostViews(get_the_ID()); ?>
也就是类似这句的下面,代码如下:
<?php if (have_posts()):while (have_posts()):the_post(); ?>
最后,将调用显示阅读次数代码加到single模版适当的位置,代码如下:
<?php echo getPostViews(get_the_ID()); ?>
如果想在其它位置显示阅读次数,可以将下面代码也加到functions模版中:
remove_action(’wp_head’,’adjacent_posts_rel_link_wp_head’,10,0);
这样就实现了wordpress不用插件来显示文章浏览量的功能了.
第二种, 比较简单—找到functions模板,加入以下代码:
//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 , $count + 1); } } } add_action(‘get_header’, ‘set_post_views’);加入到主题functions模版文件中,直接调用<?php get_post_views($post -> ID); ?> views 到文章页面即可.
