BBS\templates\lang\zh-cn\dispbbs.lang.php

找到  

,'tpl.str210' => '<b>个人贴子管理</b>：'

在其下面增加

 ,'tpl.str301' => '上传附件'

BBS\templates\default\dispbbs.tpl.php

大约800行左右 查找

<form id="Dvform" name="Dvform" action="savepost.php?action=sre&method=fastreply&boardid={$TopicInfo['boardid']}&star={$GLOBALS['star']}&page={$GLOBALS['page']}{$fragment}"disabled_by_dv__onkeydown="ctlent();"disabled_by_dv__onsubmit="Dvbbs_CopyData('Body');" method="post">

在下面增加三行如下：

<input type="hidden" name="upfilerename" />
<input type="hidden" name="__upload_subdir" />
<input type="hidden" name="__upfileinfo" />

继续往下 7行，找到
<div class="th" style="margin-top : 20px;"><div style="float:left;">&nbsp;&nbsp;{$lang['tpl.str182']}</div>{$gettitle}</div>

在下面增加几行 如下

<div id="dv_topic_1" class="postlary2" style="border-bottom:0px;display:none;">
<div class="postuserinfo" style="border-right: 1px solid #6E98C5;text-align:left;height:30px;line-height:30px;">
<b>{$lang['tpl.str300']}：</b>
</div>
<div class="postie" style="padding:0px;height:30px;text-align:left;background-color:#FFFFFF;"><input name="topic" id="topic" size="53" class="FormClass" value="" style="margin-top:3px;" />&nbsp;{$lang['tpl.str300.1']}
</div>
</div>
<div id="dv_topic_2" class="postlary2" style="border-bottom:0px;display:none;">
<div class="postuserinfo" style="border-right: 1px solid #6E98C5;text-align:left;height:30px;line-height:30px;">

<div class="postie" style="padding:0px;height:30px;text-align:left; "><iframe name="ad" frameborder="0" width="100%" height="28" scrolling="no" src="post_upload.php?boardid={$boardid}"></iframe>
</div>
</div>

然后继续向下找20多行左右，找到

<img src="images/post/icon_alipay.gif" alt="{$lang['tpl.str155']}" class="icoover"disabled_by_dv__onmouseover="this.className='icoovermouseover';"disabled_by_dv__onmouseout="this.className='icoover';"disabled_by_dv__onclick="Dvbbs_UserDialog('InsertAlipay');this.className='icoonclick';"/>
</div>
</div>

在两个</div>上面插入如下面红色代码！

<img src="images/post/icon_alipay.gif" alt="{$lang['tpl.str155']}" class="icoover"disabled_by_dv__onmouseover="this.className='icoovermouseover';"disabled_by_dv__onmouseout="this.className='icoover';"disabled_by_dv__onclick="Dvbbs_UserDialog('InsertAlipay');this.className='icoonclick';"/>

<div style="float:left;height:30px;line-height:30px;">
<input type="checkbox" id="dv_checkb3" name="dv_checkb3" style="margin:5px;"disabled_by_dv__onclick="if(this.checked){document.getElementById('dv_topic_2').style.display='';}else{document.getElementById('dv_topic_2').style.display='none';}" class="chkbox"><label for="dv_checkb3" style="cursor:hand">{$lang['tpl.str301']}</label></div>

<input type="hidden" name="uploadrepl" value="">

如果这样查看不方便，我提供TXT文本，大家可以查看文本说明！

如果想让大家点击后系统能记住显示状态，就需要增加记录cookies，请设置完毕上面的按照下面继续设置：

找到 

function LoadMagicEmot(MMID,MagicID,topicid){
 var cookiesstr=readCookie('mofaface_'+ topicid);
 if (cookiesstr ==null){
  createCookie('mofaface_'+ topicid,MagicID,30)
  DispMagicEmot(MMID,MagicID,350,500)
 }
}
</script>

，在</script>上一行增加

function LoadMagicEmot(MMID,MagicID,topicid){
 var cookiesstr=readCookie('mofaface_'+ topicid);
 if (cookiesstr ==null){
  createCookie('mofaface_'+ topicid,MagicID,30)
  DispMagicEmot(MMID,MagicID,350,500)
 }
}
function Set_Cookie(name,value)
{
    var Days = 365;
    var exp  = new Date();
    exp.setTime(exp.getTime() + Days*24*60*60*1000);
    document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function get_Cookie(name)
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;
}
</script>

然后继续找到

<div style="float:left;height:30px;line-height:30px;">
<input type="checkbox" id="dv_checkb1" name="dv_checkb1" style="margin:5px;"disabled_by_dv__onclick="if(this.checked){document.getElementById('dv_topic_1').style.display='';}else{document.getElementById('dv_topic_1').style.display='none';}" class="chkbox"><label for="dv_checkb1" style="cursor:hand">{$lang['tpl.str300']}</label></div>
<div style="float:left;height:30px;line-height:30px;">
<input type="checkbox" id="dv_checkb3" name="dv_checkb3" style="margin:5px;"disabled_by_dv__onclick="if(this.checked){document.getElementById('dv_topic_2').style.display='';}else{document.getElementById('dv_topic_2').style.display='none';}" class="chkbox"><label for="dv_checkb3" style="cursor:hand">{$lang['tpl.str301']}</label></div>

改为

<div style="float:left;height:30px;line-height:30px;">
<input type="checkbox" id="dv_checkb1" name="dv_checkb1" style="margin:5px;"disabled_by_dv__onclick="if(this.checked){document.getElementById('dv_topic_1').style.display='';Set_Cookie('retitle','1');}else{document.getElementById('dv_topic_1').style.display='none';Set_Cookie('retitle','0');}" class="chkbox"><label for="dv_checkb1" style="cursor:hand">{$lang['tpl.str300']}</label></div>
<div style="float:left;height:30px;line-height:30px;">

然后继续找到

<script language="Javascript" type="text/javascript">
var Dvbbs_bIsIE5=document.all;
var Dvbbs_Mode = 3;
if (Dvbbs_bIsIE5)
{var IframeID=frames["Dvbbs_Composition"];}
else
{
var IframeID=document.getElementById("Dvbbs_Composition").contentWindow;
}
function Gopreview()
{
document.preview.theBody.value=IframeID.document.body.innerHTML;
var popupWin = window.open('', 'preview_page', 'scrollbars=yes,width=750,height=450');
document.preview.submit()
}
Dvbbs_InitDocument('Body','gb2312');
</script>

改为

<script language="Javascript" type="text/javascript">
var Dvbbs_bIsIE5=document.all;
var Dvbbs_Mode = 3;
if (Dvbbs_bIsIE5)
{var IframeID=frames["Dvbbs_Composition"];}
else
{
var IframeID=document.getElementById("Dvbbs_Composition").contentWindow;
}
function Gopreview()
{
document.preview.theBody.value=IframeID.document.body.innerHTML;
var popupWin = window.open('', 'preview_page', 'scrollbars=yes,width=750,height=450');
document.preview.submit()
}
Dvbbs_InitDocument('Body','gb2312');
if(get_Cookie("retitle")=="1"){document.getElementById('dv_topic_1').style.display='';document.getElementById('dv_checkb1').checked=true;}
if(get_Cookie("reupload")=="1"){document.getElementById('dv_topic_2').style.display='';document.getElementById('dv_checkb3').checked=true;}
</script>

OK了！！！

再次补充：

修改完毕，上传文件可能会有JS脚本错误，请打开 BBS\templates\default\dispbbs.tpl.php  找到

<input style="margin:3px;" type="reset" name="Clear" value="{$lang['tpl.str185']}"disabled_by_dv__onclick="ClearReset()" class="button"/>

改为

<input style="margin:3px;" type="reset" name="Submit2" value="{$lang['tpl.str185']}"disabled_by_dv__onclick="ClearReset()" class="button"/>

 即可！！！
