exist-upload

xquery version "1.0";

declare function local:upload() {

let $filename := request:get-uploaded-file-name('file')

return
<results>
   <message>File {$filename} has been stored.</message>
</results>

};

local:upload()

Something like this?

declare function app:upload($node as node(), $model as map(*)) {
   
let $collection := 'db/apps/NiC/inReview'
let $filename := request:get-uploaded-file-name('file')
let $file := util:binary-to-string($filename)

(: make sure you use the right user permissions that has write access to this collection :)
let $login := xmldb:login($collection, 'username', 'superhardpassword')
let $store as xs:string? := xmldb:store($collection, $filename, request:get-uploaded-file-data($file), 'application/octet-stream')
(:let $store := xmldb:store($collection, $filename, request:get-uploaded-file-data('file')):) 

I'm sure the syntax is incorrect--I figured I'd try to break something, but I am still receiving the "problem accessing form1.html" SAX exception. So I'm not sure the app:upload is even being run. I'll continue to play with it!

(untested)

declare function app:upload($node as node(), $model as map(*)) {
   
let $collection := 'db/apps/NiC/inReview'
let $filename := request:get-uploaded-file-name('file')
let $file := util:binary-to-string(request:get-uploaded-file-data('file'))

(: make sure you use the right user permissions that has write access to this collection :)
let $login := xmldb:login($collection, 'username', 'superhardpassword')
let $store as xs:string? := xmldb:store($collection, $filename, $file)
(:let $store := xmldb:store($collection, $filename, request:get-uploaded-file-data('file')):) 

Okay, so I got it to work--but in a very strange way. Do you have any insight? I think it's a controller/path issue, but why it works now and doesn't if I trust the controller to do what it's supposed to do is frustrating to no end: https://stackoverflow.com/questions/47182646/uploading-documents-to-a-server-using-xql-exist-db
