今天在论坛发布了一个excel文档，发现有一个大问号，搜索了一下遇见这个问题的还挺多，不过还好有大神，所以我的问题也解决了，特此记录一下。
Discuz！ x3.2 附件图标问号的解决方法
1、将图标上传到目录：static\image\filetype 保存为你需要的名字，比如我的，xls.gif
2、打开文件，路径为：\source\function\function_attachment.php
其实打开就能看到下面这些内容，：
function attachtype($type, $returnval = ‘html’) {
static $attachicons = array(
1 => ‘unknown.gif’,
2 => ‘binary.gif’,
3 => ‘zip.gif’,
4 => ‘rar.gif’,
5 => ‘msoffice.gif’,
6 => ‘text.gif’,
7 => ‘html.gif’,
8 => ‘real.gif’,
9 => ‘av.gif’,
10 => ‘flash.gif’,
11 => ‘image.gif’,
12 => ‘pdf.gif’,
13=> ‘torrent.gif’
);
修改为你要添加的图标名称，例如我的，在12和13中间加上这些：
function attachtype($type, $returnval = ‘html’) {
static $attachicons = array(
1 => ‘unknown.gif’,
2 => ‘binary.gif’,
3 => ‘zip.gif’,
4 => ‘rar.gif’,
5 => ‘msoffice.gif’,
6 => ‘text.gif’,
7 => ‘html.gif’,
8 => ‘real.gif’,
9 => ‘av.gif’,
10 => ‘flash.gif’,
11 => ‘image.gif’,
12 => ‘pdf.gif’,
13 => ‘xls.gif’,
14 => ‘doc.gif’,
15 => ‘ppt.gif’,
16 => ‘torrent.gif’
);
上面添加图标的修改完了，下面的也需要修改，搜索：
if(is_numeric($type)) {
$typeid = $type;
} else {
if(preg_match(“/bittorrent|^torrent\t/”, $type)) {
$typeid = 13;
} elseif(preg_match(“/pdf|^pdf\t/”, $type)) {
$typeid = 12;
} elseif(preg_match(“/image|^(jpg|gif|png|bmp)\t/”, $type)) {
$typeid = 11;
} elseif(preg_match(“/flash|^(swf|fla|flv|swi)\t/”, $type)) {
$typeid = 10;
} elseif(preg_match(“/audio|video|^(wav|mid|mp3|m3u|wma|asf|asx|vqf|mpg|mpeg|avi|wmv)\t/”, $type)) {
$typeid = 9;
} elseif(preg_match(“/real|^(ra|rm|rv)\t/”, $type)) {
$typeid = 8;
} elseif(preg_match(“/htm|^(php|js|pl|cgi|asp)\t/”, $type)) {
$typeid = 7;
} elseif(preg_match(“/text|^(txt|rtf|wri|chm)\t/”, $type)) {
$typeid = 6;
} elseif(preg_match(“/word|powerpoint|^(doc|ppt)\t/”, $type)) {
$typeid = 5;
} elseif(preg_match(“/^rar\t/”, $type)) {
$typeid = 4;
} elseif(preg_match(“/compressed|^(zip|arj|arc|cab|lzh|lha|tar|gz)\t/”, $type)) {
$typeid = 3;
} elseif(preg_match(“/octet-stream|^(exe|com|bat|dll)\t/”, $type)) {
$typeid = 2;
} elseif($type) {
$typeid = 1;
} else {
$typeid = 0;
}
}
修改为：
if(is_numeric($type)) {
$typeid = $type;
} else {
if(preg_match(“/bittorrent|^torrent\t/”, $type)) {
$typeid = 16;
} elseif(preg_match(“/office|^(ppt)\t/”, $type)) {
$typeid = 15;
} elseif(preg_match(“/office|^(doc|docx)\t/”, $type)) {
$typeid = 14;
} elseif(preg_match(“/office|^(xls|xlsx)\t/”, $type)) {
$typeid = 13;
} elseif(preg_match(“/pdf|^pdf\t/”, $type)) {
$typeid = 12;
} elseif(preg_match(“/image|^(jpg|gif|png|bmp)\t/”, $type)) {
$typeid = 11;
} elseif(preg_match(“/flash|^(swf|fla|flv|swi)\t/”, $type)) {
$typeid = 10;
} elseif(preg_match(“/audio|video|^(wav|mid|mp3|m3u|wma|asf|asx|vqf|mpg|mpeg|avi|wmv)\t/”, $type)) {
$typeid = 9;
} elseif(preg_match(“/real|^(ra|rm|rv)\t/”, $type)) {
$typeid = 8;
} elseif(preg_match(“/htm|^(php|js|pl|cgi|asp)\t/”, $type)) {
$typeid = 7;
} elseif(preg_match(“/text|^(txt|rtf|wri|chm)\t/”, $type)) {
$typeid = 6;
} elseif(preg_match(“/word|powerpoint|^(doc|ppt)\t/”, $type)) {
$typeid = 5;
} elseif(preg_match(“/^rar\t/”, $type)) {
$typeid = 4;
} elseif(preg_match(“/compressed|^(zip|arj|arc|cab|lzh|lha|tar|gz)\t/”, $type)) {
$typeid = 3;
} elseif(preg_match(“/octet-stream|^(exe|com|bat|dll)\t/”, $type)) {
$typeid = 2;
} elseif($type) {
$typeid = 1;
} else {
$typeid = 0;
}
}
修改完成，登陆后台，更新缓存，上传文件测试一下就可以了。

修改后：
到这里大家应该能看明白了，需要哪些图标就自己添加就可以了，这个还是比较简单的哈。
附上我的图标，有需要的小伙伴可以一并带走哈
（右键另存为就可以了）
