最近在使用wordpress做网站的时候在列表页文章的发布时间需要显示为发布于xx之前的时候没有找到合适的方法,网上的调用方法几乎都是一样。但是没有发现自己想要的格式。正好前段时间我们的同事博客中想添加一个文章发布时间,但是不想用常规发布时间年月日来显示,显示为发布于xx前这种样式,我就用自定义了一个函数计算当前和发布的时间差来实现这一功能,今天偶然发现,wordpress主题已经内置这个函数了,代码如下
while (have_posts()) : the_post();
echo '发布于' . human_time_diff( get_the_time( 'U' ), current_time( 'timestamp' ) ) . ' 前';
endwhile;
实现这一功能的函数就是human_time_diff();把实现代码也贴出来,以供大家在其他非wordpress项目中使用做参考,写的还是很不错的
function human_time_diff( $from, $to = 0 ) {
if ( empty( $to ) ) {
$to = time();
}
$diff = (int) abs( $to - $from );
if ( $diff < MINUTE_IN_SECONDS ) {
$secs = $diff;
if ( $secs <= 1 ) {
$secs = 1;
}
/* translators: Time difference between two dates, in seconds. %s: Number of seconds. */
$since = sprintf( _n( '%s second', '%s seconds', $secs ), $secs );
} elseif ( $diff < HOUR_IN_SECONDS && $diff >= MINUTE_IN_SECONDS ) {
$mins = round( $diff / MINUTE_IN_SECONDS );
if ( $mins <= 1 ) {
$mins = 1;
}
/* translators: Time difference between two dates, in minutes (min=minute). %s: Number of minutes. */
$since = sprintf( _n( '%s min', '%s mins', $mins ), $mins );
} elseif ( $diff < DAY_IN_SECONDS && $diff >= HOUR_IN_SECONDS ) {
$hours = round( $diff / HOUR_IN_SECONDS );
if ( $hours <= 1 ) {
$hours = 1;
}
/* translators: Time difference between two dates, in hours. %s: Number of hours. */
$since = sprintf( _n( '%s hour', '%s hours', $hours ), $hours );
} elseif ( $diff < WEEK_IN_SECONDS && $diff >= DAY_IN_SECONDS ) {
$days = round( $diff / DAY_IN_SECONDS );
if ( $days <= 1 ) {
$days = 1;
}
/* translators: Time difference between two dates, in days. %s: Number of days. */
$since = sprintf( _n( '%s day', '%s days', $days ), $days );
} elseif ( $diff < MONTH_IN_SECONDS && $diff >= WEEK_IN_SECONDS ) {
$weeks = round( $diff / WEEK_IN_SECONDS );
if ( $weeks <= 1 ) {
$weeks = 1;
}
/* translators: Time difference between two dates, in weeks. %s: Number of weeks. */
$since = sprintf( _n( '%s week', '%s weeks', $weeks ), $weeks );
} elseif ( $diff < YEAR_IN_SECONDS && $diff >= MONTH_IN_SECONDS ) {
$months = round( $diff / MONTH_IN_SECONDS );
if ( $months <= 1 ) {
$months = 1;
}
/* translators: Time difference between two dates, in months. %s: Number of months. */
$since = sprintf( _n( '%s month', '%s months', $months ), $months );
} elseif ( $diff >= YEAR_IN_SECONDS ) {
$years = round( $diff / YEAR_IN_SECONDS );
if ( $years <= 1 ) {
$years = 1;
}
/* translators: Time difference between two dates, in years. %s: Number of years. */
$since = sprintf( _n( '%s year', '%s years', $years ), $years );
}
