dedecms织梦把发布时间改成多少时间前

1、找到include/extend.func.php，在最后面添加

function conversionTime ($time) {
	$today = Floor(time()/(3600 * 24));
	$senday= Floor($time/(3600 * 24));
	$updays = $today-$senday;
	if($updays==0)
		$str = '今天';
	elseif ($updays >=1 && $updays < 31) {
        $str = $updays.'天前 ';
	}
	elseif ($updays >0 && $updays < 1 ) {
		$h = floor($updays * 24);
		$str = $h.'小时前 ';
	}
	elseif ($updays >= 31&& $updays < 365) {
		$m = floor($updays / 31);
		$str = $m.'月前 ';
	}
    elseif ($updays >= 31&& $updays < 365) {
        $y = floor($updays / (31* 365));
        $str = $y.'年前 ';
	}
	else {
        $str = $rtime;
	}
	return $str;
}

2、调用方法

列表页：[field:pubdate function="conversionTime(@me)" /]
