打开
.\include\global.func.php
查找(在最后几行)
function discuz_uc_avatar($uid, $size = '') {
return UC_API.'/avatar.php?uid='.$uid.'&size='.$size;
}
替换
function discuz_uc_avatar($uid, $size = '') {
global $db, $tablepre;
$query = $db->fetch_first("SELECT avatar FROM {$tablepre}memberfields where uid = $uid");
if($query['avatar'] != "") return $query['avatar'];
$avatar = $discuz_root.'./images/avatars/customavatars/'.$uid.'.jpg';
if(file_exists($avatar)) return $avatar;
return UC_API.'/avatar.php?uid='.$uid.'&size='.$size;
}
官方 0606 补丁修改内容
查找:
function discuz_uc_avatar($uid, $size = '', $returnsrc = FALSE) {
$size = in_array($size, array('big', 'middle', 'small')) ? $size : 'middle';
$uid = abs(intval($uid));
$uid = sprintf("%09d", $uid);
$dir1 = substr($uid, 0, 3);
$dir2 = substr($uid, 3, 2);
$dir3 = substr($uid, 5, 2);
return $returnsrc ? UC_API.'/data/avatar/'.$dir1.'/'.$dir2.'/'.$dir3.'/'.substr($uid, -2)."_avatar_$size.jpg" : '<img src="'.UC_API.'/data/avatar/'.$dir1.'/'.$dir2.'/'.$dir3.'/'.substr($uid, -2)."_avatar_$size.jpg".'" onerror="this.onerror=null;this.src=\''.UC_API.'/images/noavatar_'.$size.'.gif\'">';
}
替换为(这里解决了无头像红叉问题和flash头像失效问题)
