wordpress twentytwenty主题访问计数

也不知道为什么wordpress官方主题中从来不加入文章访问计数，就像以前的ios从来不加android功能一样。2020换了wordpress twentytwenty主题，加入文章计数。

funtions.php中加入下面code

/* 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;
}

inc/template-tags.php中找到

				// Comments link.
				if ( in_array( 'comments', $post_meta, true ) && ! post_password_required() && ( comments_open() || get_comments_number() ) ) {

					$has_meta = true;
					?>
					<li class="post-comment-link meta-wrapper">
						<span class="meta-icon">
							<?php twentytwenty_the_theme_svg( 'comment' ); ?>
						</span>
						<span class="meta-text">
							<?php comments_popup_link(); ?>
						</span>
					</li>
					<?php

				}

在其后面插入

				// Views.
				if ( in_array( 'views', $post_meta, true ) ) {

					$has_meta = true;
					?>
					<li class="post-views meta-wrapper">
						<span class="meta-icon">
							<span class="screen-reader-text"><?php _e( 'Post views', 'twentytwenty' ); ?></span>
							<?php twentytwenty_the_theme_svg( 'views' ); ?>
						</span>
						<span class="meta-text">
							<?php post_views(' ', ' views'); ?> 
						</span>
					</li>
					<?php

				}

还是在inc/template-tags.php中找到下面一段加入views
下面code中已加好

		$post_meta = apply_filters(
			'twentytwenty_post_meta_location_single_top',
			array(
				'author',
				'post-date',
				'comments',
				'sticky',
				'categories',
				'views',
			)
		);

这样就应该能看到计数了

如果还想丰富点，能加个svg图标，就需要打开classes/class-twentytwenty-svg-icons.php, 找到下面的array

public static $ui_icons = array(

在其中加入下面的code

			'views'          => '<svg xmlns="http://www.w3.org/2000/svg" width="17" height="18" viewBox="0 0 32 32	">
