分享JAVASCRIPT动态添加表单，多个文件上传问题
问题是用IE浏览器，上传，始终最后一个文件没法上传上成功，获取的TMP_NAME,NAME都为空，用Firefox更坏，始终只能上传一个文件，其它所有添加的文件都上传不了，郁闷

var aElement=document.createElement("input");
aElement.name=nm;
aElement.id=nm;
aElement.type="file";
aElement.size="50";
aElement.value="30000";
=====================================
这个要改一下：
try{
var aElement=document.createElement("<input type='file' name='"+nm+"' id='"+nm+"'>");
}catch(e){
var aElement=document.createElement("input");
aElement.name=nm;
aElement.id=nm;
aElement.type="file";
}
aElement.size="50";
aElement.value="30000";
aElement.name=nm;
aElement.id=nm;
aElement.type="file";
aElement.size="50";
aElement.value="30000";

别的没细看,不过不久前才遇过firefox里同样的问题,
你要把<form>和</form>移到<table>外面,不要放在<table>里,
这样firefox里的问题就好了

把表单定义为数组吧！然后再循环！

给你端js，如果去掉option这个功能就可以兼容火狐，ie，opera，safari，如果不去的只能兼容ie，safari，opera
<span id='idfilespan'></span><br />
<a id=attach onclick="addFile('idfilespan','filename')" href="javascript:;">添加内容</a>
var i1 = 1;
function addFile(dvID,inputNamePrefix)
{
var dv = document.getElementById(dvID);
var file = document.createElement("label");
file.innerHTML = "第"+i1+"集 ";
var file1 = document.createElement("select");
file1.name = "ftype[]";
file1.id=i1;
file1.onchange = function() {

给你个现成的，上传的表单name是guide[]是一个数组啊，别写错了
$f_type=strtolower("flv,swf,jpg,png");//设置可上传的文件类型
$file_size_max=500*1024*1024;//限制单个文件上传最大容量500M
$overwrite = 0;//是否允许覆盖相同文件,1:允许,0:不允许
$f_input="guide";//设置上传域名称，数组的名称
$m=0;
foreach($_FILES[$f_input]["error"] as $key => $error){
$up_error="no";
if ($error == UPLOAD_ERR_OK){
if(!$ftype[$m]){
$up_error="yes";
}
$f_name=$_FILES[$f_input]['name'][$key];//获取上传源文件名
$uploadfile=$uploaddir.strtolower(basename($f_name));
$tmp_type=substr(strrchr($f_name,"."),1);//获取文件扩展名
$tmp_type=strtolower($tmp_type);
if(!stristr($f_type,$tmp_type)){
echo "对不起,不能上传".$tmp_type."格式文件, ".$f_name." 文件上传失败!<br
/>";
$up_error="yes";
}
if ($_FILES[$f_input]['size'][$key]>$file_size_max) {
echo "对不起,你上传的文件 ".$f_name." 容量为".round($_FILES[$f_input]
['size'][$key]/1024)."Kb,大于规定的".($file_size_max/1024)."Kb,上传失败!<br />";
$up_error="yes";
}
if (file_exists(".".$uploadfile)&&!$overwrite){
echo "对不起,文件 ".$f_name." 已经存在,上传失败!<br />";
$up_error="yes";
}
$string = 'abcdefghijklmnopgrstuvwxyz0123456789';
$rand = '';
for ($x=0;$x<12;$x++)
$rand .= substr($string,mt_rand(0,strlen($string)-1),1);
$t=date("ymdHis").substr($gettime[0],2,6).$rand;
$attdir=$flash_path.$sort."/";
if(!is_dir(".".$attdir))
{ mkdir(".".$attdir);}
$uploadfile=$attdir.$t.".".$tmp_type;
if(($up_error!="yes") and (move_uploaded_file($_FILES[$f_input]['tmp_name']
[$key],".".$uploadfile))){
$temp[$m]=$uploadfile;//上传文件地址
echo "文件 ".$f_name." 上传成功!<br />";
}
}
$m++;
}

你是想用php同时上传多个文件吗，写个循环就行了，我写过的，要是用到js那我就不怎么会了。你先把意图说清楚！！！！
