每个网站底部都会出现一个版权日期,比如web建站建站的版权日期是Copyright©2019-2023
,那么如何实现每年自动更新呢?
function ipkd_copyright() { global $wpdb; $copyright_dates = $wpdb->get_results("SELECT YEAR(min(post_date_gmt)) AS firstdate, YEAR(max(post_date_gmt)) AS lastdate FROM $wpdb->posts WHERE post_status = 'publish'"); $output = ''; if( $copyright_dates ) { $copyright = "© " . $copyright_dates[0]->firstdate; if( $copyright_dates[0]->firstdate != $copyright_dates[0]->lastdate ) { $copyright .= '-' . $copyright_dates[0]->lastdate; } $output = $copyright; } return $output; }
在页面中调用一以下代码:
<?php echo ipkd_copyright(); ?>
