Forgot the code:
Some needed import:
import _root_.scala.xml.{NodeSeq, Text, Group}
The xhtml:
<lift:snippet type="data:upload" form="post" multipart="true">
<choose:post>
<p>
File name: <ul:file_name/><br />
MIME Type: <ul:mime_type/><br />
File length: <ul:length/><br />
MD5 Hash: <ul:md5/><br />
</p>
</choose:post>
<choose:get>
Select a file to upload: <ul:file_upload/><br />
<input type="submit" value="Upload File"/>
</choose:get>
</lift:snippet>
The snippet:
private object theUpload extends RequestVar[Box[FileParamHolder]]
(Empty)
def upload(xhtml: NodeSeq): NodeSeq =
if (S.get_?) bind("ul", chooseTemplate("choose", "get", xhtml),
"file_upload" -> fileUpload(ul => theUpload(Full
(ul))))
else {
bind("ul", chooseTemplate("choose", "post", xhtml),//else:
It's a POST
"file_name" -> theUpload.is.map(v => Text(v.fileName)),
"mime_type" -> theUpload.is.map(v => Box.legacyNullTest
(v.mimeType).map(Text).openOr(Text("No mime type supplied"))), // Text
(v.mimeType)),
"length" -> theUpload.is.map(v => Text
(v.file.length.toString)),
"md5" -> theUpload.is.map(v => Text(hexEncode(md5
(v.file))))
)
}
