纯代码实现WORDPRESS阅读量统计，省去WP-POSTVIEWS插件！

作为一个小白，玩wordpress主题的时候经常喜欢安装一些插件来增加wordpress的功能性，比如说wordpress阅读量统计功能，比如说WP-PostViews插件。。。之后发现，插件安装的越多，wordpress速度越来越慢，之后经过度娘的查询后发现，安装过多的插件对wordpress主题速度影响非常大，因为会产生很多的查询，造成了数据变慢，而最近小编的网站正在渐渐的代码化了，把能够代码完成尽可能的去代码完成，wordpress瘦身，从wordpress插件的减少使用开始！

那么今天小编要讲的就是通过代码实现wordpress阅读统计功能，就有一个必须要安装的插件WP-PostViews，而且还不能升级。今天闲来无事，捣鼓了一番，整理出来了解决方案，下面说重点了！

基本我们使用WP-PostViews插件都是想有统计和阅读数的功能，那么下面的一段代码就是来实现这两个功能的！

首先在寻找到functions.php文件，在最后面加入下面的代码

/* 访问计数 */
function record_visitors()
{
    if (is_singular())
    {
      global $post;
      $post_ID = $post->ID;
      if($post_ID)
      {
          $post_views = (int)get_post_meta($post_ID, 'views', true);
          if(!update_post_meta($post_ID, 'views', ($post_views+1)))
          {
            add_post_meta($post_ID, 'views', 1, true);
          }
      }
    }
}
add_action('wp_head', 'record_visitors');
/// 函数名称：post_views
/// 函数作用：取得文章的阅读次数
function post_views($before = '(点击 ', $after = ' 次)', $echo = 1)
{
  global $post;
  $post_ID = $post->ID;
  $views = (int)get_post_meta($post_ID, 'views', true);
  if ($echo) echo $before, number_format($views), $after;
  else return $views;
}

/* 访问计数 */

function record_visitors()

{

if (is_singular())

{

global $post;

$post_ID = $post->ID;

if($post_ID)

{

$post_views = (int)get_post_meta($post_ID, 'views', true);

if(!update_post_meta($post_ID, 'views', ($post_views+1)))

{

add_post_meta($post_ID, 'views', 1, true);

}

add_action('wp_head', 'record_visitors');

/// 函数名称：post_views

/// 函数作用：取得文章的阅读次数

function post_views($before = '(点击 ', $after = ' 次)', $echo = 1)

{

global $post;

$post_ID = $post->ID;

$views = (int)get_post_meta($post_ID, 'views', true);

if ($echo) echo $before, number_format($views), $after;

else return $views;

}

代码放好后，保存，然后到主题前端位置添加调用

阅读：<?php post_views(' ', ' 次'); ?>

1	阅读：<?php post_views(' ', ' 次'); ?>

获取阅读次数最多的文章
如果要获取上面的函数统计出来的阅读次数最多的文章，可以在 functions.php文件的最后添加下面的代码：

// get_most_viewed_format
// 函数作用：取得阅读最多的文章
function get_most_viewed_format($mode = '', $limit = 10, $show_date = 0, $term_id = 0, $beforetitle= '(', $aftertitle = ')', $beforedate= '(', $afterdate = ')', $beforecount= '(', $aftercount = ')') {
  global $wpdb, $post;
  $output = '';
  $mode = ($mode == '') ? 'post' : $mode;
  $type_sql = ($mode != 'both') ? "AND post_type='$mode'" : '';
  $term_sql = (is_array($term_id)) ? "AND $wpdb->term_taxonomy.term_id IN (" . join(',', $term_id) . ')' : ($term_id != 0 ? "AND $wpdb->term_taxonomy.term_id = $term_id" : '');
  $term_sql.= $term_id ? " AND $wpdb->term_taxonomy.taxonomy != 'link_category'" : '';
  $inr_join = $term_id ? "INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)" : '';
  // database query
  $most_viewed = $wpdb->get_results("SELECT ID, post_date, post_title, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON ($wpdb->posts.ID = $wpdb->postmeta.post_id) $inr_join WHERE post_status = 'publish' AND post_password = '' $term_sql $type_sql AND meta_key = 'views' GROUP BY ID ORDER BY views DESC LIMIT $limit");
  if ($most_viewed) {
   foreach ($most_viewed as $viewed) {
    $post_ID    = $viewed->ID;
    $post_views = number_format($viewed->views);
    $post_title = esc_attr($viewed->post_title);
    $get_permalink = esc_attr(get_permalink($post_ID));
    $output .= "<li>$beforetitle$post_title$aftertitle";
    if ($show_date) {
      $posted = date(get_option('date_format'), strtotime($viewed->post_date));
      $output .= "$beforedate $posted $afterdate";
    }
    $output .= "$beforecount $post_views $aftercount</li>";
   }
  } else {
   $output = "<li>N/A</li>n";
  }
  echo $output;
}

// get_most_viewed_format

// 函数作用：取得阅读最多的文章

function get_most_viewed_format($mode = '', $limit = 10, $show_date = 0, $term_id = 0, $beforetitle= '(', $aftertitle = ')', $beforedate= '(', $afterdate = ')', $beforecount= '(', $aftercount = ')') {

global $wpdb, $post;

$output = '';

$mode = ($mode == '') ? 'post' : $mode;

$type_sql = ($mode != 'both') ? "AND post_type='$mode'" : '';

$term_sql = (is_array($term_id)) ? "AND $wpdb->term_taxonomy.term_id IN (" . join(',', $term_id) . ')' : ($term_id != 0 ? "AND $wpdb->term_taxonomy.term_id = $term_id" : '');

$term_sql.= $term_id ? " AND $wpdb->term_taxonomy.taxonomy != 'link_category'" : '';

$inr_join = $term_id ? "INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)" : '';

// database query

$most_viewed = $wpdb->get_results("SELECT ID, post_date, post_title, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON ($wpdb->posts.ID = $wpdb->postmeta.post_id) $inr_join WHERE post_status = 'publish' AND post_password = '' $term_sql $type_sql AND meta_key = 'views' GROUP BY ID ORDER BY views DESC LIMIT $limit");

if ($most_viewed) {

foreach ($most_viewed as $viewed) {

$post_ID = $viewed->ID;

$post_views = number_format($viewed->views);

$post_title = esc_attr($viewed->post_title);

$get_permalink = esc_attr(get_permalink($post_ID));

$output .= "<li>$beforetitle$post_title$aftertitle";

if ($show_date) {

$posted = date(get_option('date_format'), strtotime($viewed->post_date));

$output .= "$beforedate $posted $afterdate";

}

$output .= "$beforecount $post_views $aftercount</li>";

}

} else {

$output = "<li>N/A</li>n";

}

echo $output;

}

然后使用下面的函数调用：

<?php get_most_viewed_format(); ?>

1	<?php get_most_viewed_format(); ?>
