XQuery/Uploading Files

Motivation You want to upload files to your eXist database using simple HTML forms. Method We will use the HTML <input> element in the web form and the store function in an XQuery. HTML Form We will use a standard HTML form but we will add a enctype="multipart/form-data" attribute. <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>HTML Upload</title> </head> <body> <form enctype="multipart/form-data" method="post" action="upload.xq"> <fieldset> <legend>Upload Document:</legend> <input type="file" name="file"/> <input type="submit" value="Upload"/> </fieldset> </form> </body> </html> Screen Image: Image:Upload-image.png XQuery On the server side, we will use the request:get-uploaded-file-name() to get the name of the incoming file and the request:get-uploaded-file-data() function to get the data from the file. We can then used the xmldb:store() function to save the file. File: upload.xq let $collection := '/db/test/upload-test' let $filename := request:get-uploaded-file-name('file') (: make sure you use the right user permissions that has write access to this collection :) let $login := xmldb:login($collection, 'admin', 'my-admin-password') let $store := xmldb:store($collection, $filename, request:get-uploaded-file-data('file')) return <results> <message>File {$filename} has been stored at collection={$collection}.</message> </results> Acknowledgments This example was posted on the eXist open mailing list by Rémi Arnaud on Nov. 05, 2010.
