discuz3.4 手机版收费附件不显示的bug修复
手机触屏版，收费附件，用户未登录时可以看到附件并有“登录后可见”的字样，但是等到登陆后却踪迹全无。有些站长反馈说在PC端购买过这个附件的，在手机端才能显示附件
这样导致手机端的附件平白无故的消失了~ 应该算是一个比较大的功能上的bug，由于不影响安全，所以官方并未急于修复。
修复起来倒是不很复杂，过程如下（如果懒得了解，可以直接拉到底部，下载懒人包，覆盖到根目录即可）
打开：/upload/source/language/lang_message.php
'attachment_buyall' => '本帖所有附件购买成功 ',
改
'attachment_mobile_buy' => '附件购买成功',
打开：/upload/source/module/forum/forum_misc.php
if(count($aids) > 1) {
showmessage('attachment_buyall', 'forum.php?mod=redirect&goto=findpost&ptid='.$attach['tid'].'&pid='.$attach['pid']);
} else {
$_G['forum_attach_filename'] = $attach['filename'];
showmessage('attachment_buy', "forum.php?mod=attachment&aid=$aidencode", array('filename' => $_G['forum_attach_filename']), array('redirectmsg' => 1));
}改
if(defined('IN_MOBILE')) {
showmessage('attachment_mobile_buy', 'forum.php?mod=redirect&goto=findpost&ptid='.$attach['tid'].'&pid='.$attach['pid']);
}else{
if(count($aids) > 1) {
showmessage('attachment_buyall', 'forum.php?mod=redirect&goto=findpost&ptid='.$attach['tid'].'&pid='.$attach['pid']);
} else {
$_G['forum_attach_filename'] = $attach['filename'];
showmessage('attachment_buy', "forum.php?mod=attachment&aid=$aidencode", array('filename' => $_G['forum_attach_filename']), array('redirectmsg' => 1));
}
