有没有办法把“Y中的X”放进我的侧边栏？我想我只能在一篇博客文章（比如检查内容是否为单篇）时显示它，但我希望能够看到我正在查看的文章。在过去的20分钟里，谷歌搜索“wordpress post x of y”给了我很多关于y页中x类或类似内容的信息，所以我想在这里问一下。
在single.php/sidebar.php中发布X of Y

class MY_Post_Numbers {
private $count = 0;
private $posts = array();
public function display_count() {
$this->init(); // prevent unnecessary queries
$id = get_the_ID();
echo sprintf( \'<div class="post-counter">Post number<span class="num">%s</span><span class="slash">/</span><span class="total">%s</span></div>\', $this->posts[$id], $this->count );
}
private function init() {
if ( $this->count )
return;
global $wpdb;
$posts = $wpdb->get_col( "SELECT ID FROM $wpdb->posts WHERE post_status = \'publish\' AND post_type = \'post\' ORDER BY post_date " ); // can add or change order if you want
$this->count = count($posts);
foreach ( $posts as $key => $value ) {
$this->posts[$value] = $key + 1;
}
unset($posts);
}
}
$GLOBALS[\'my_post_numbers\'] = new MY_Post_Numbers;
function my_post_number() {
$GLOBALS[\'my_post_numbers\']->display_count();
}
<?php my_post_number(); ?>
