同时上传文件和传参数的问题

这个例子是分析multipart/form-data按RFC1867文档的.注意我把值全部放到Session了,当然在你操作的时候可以放到别的地方,如果不想这么做,可以下载组件jspsmart

save.jsp??你是用jsp？
我不会，呵呵
不好意思
你要分成开成为两个表单.然后分别提交<form method="post" action="save.jsp" name="info" ENCTYPE="multipart/form-data" onsubmit="document.info2.submit();">
<input type="file" name="file1" onchange="document.info2.showcontent.value=this.value">
<input type="submit">
</form><form name="info2" target="_blank">
<input type="hidden" name="showcontent" value="111">
</form>
