File upload via Webbrowser

Hello,

after many tries in finished to understand that the first parameter doesn't reference an uniface field but the name of an input of the form.

for instance:

uniface code:

fileload/web "fichier",lv_contenu

html code:

<form target="_self" action="hguw0002.op_upload" enctype="multipart/form-data" method="post" name="formulaire">
    <input name="fichier" type="file" />
    <input value="Upload" type="submit" />
</form>

Hi Philippe,

thnx for the hint! Good to know that I'm not the only one digging around with this. I did some studies on this an found the following:

Uniface painting:
-8<-------------

<x-entity name="DUMMY.DUMMY">

<x-subst name="DATEI.DUMMY.DUMMY" type="file">
  <input value="" name="DATEI.DUMMY.DUMMY" type="file">
</x-subst>

</x-entity>
-8<-------------

the marked lines are the important in the painting, DUMMY.DUMMY is just included to get it compiled ;)

My HTML looks like:
-8<-------------

<h1>File-Upload</h1>

<form action="!THISUSP!.upload" method="post" enctype="multipart/form-data">
    <input type="file" name="DATEI">
   <br />
  <button type="submit">Senden</button>
</form>

-8<-------------

Uniface operation:

;###################################################################
operation upload
;###################################################################
variables
  ;### Parameter ###
  string  lv_bin_file
endvariables

;### UPLOADS handled here (Field "DATEI" has to be painted to let it happen!)  ###
DATEI = $item("DATEI",$webinfo("input"))
fileload/web "DATEI", lv_bin_file

$webinfo("output") = $concat("OK! loaded ",$length(lv_bin_file)," Bytes")

end

-8<-------------

In my testset this only works aslong the stuff is painted in UNIFACE aswell ! Leaving the code in the Uniface painting away lets you -300 the code! Can you confirm this? I tried this with the TECH-GUYS in Amsterdam.

Somehow it seems that FILELOAD/WEB needs the painting to know what to do! Further more the names have to be similiar ... :/

I'm waiting for the reply from the TECH GUYS so i can finish my part 04 ("HOW TO RIA with USP - handling Inputs in the right way").

cheers,

you are right,

the field "fichier" is drawn in the component in my sample.

Hi Ghan,

Please have a look at the Uniface servlet settings "Maxuploadsize" and "maxfileuploads". By default you can upload a file with size 64kb. If your file is bigger and the setting 'maxuploadsize" is not properly set, then the file gets corrupted.

Regards,

Arno

Dear Arno,

the filesize in this case won't matter ...

... the problem is that I need to "paint" a INPUT FILE in order to get it running instead of taking the data directly from $webinfo("INPUT").

any solutions on that?!

cheers,

-GHAN-

Note: for large files, uploading can be a bit memory intensive therefore, you may want to do these operations via a dedicated UST with a low maxreq/maxidle.

Thx Jas,

I'll try to keep that in mind.

Cheers,

-GHAN-
