[Zope] - Newbie alert - how to upload multiple images at once with manage_add_image

Tue, 27 Feb 2001 16:24:17 +0100

HI,
I am trying to set up a form when a user can upload three images at 
once: one for a logo, one for a city map and one for a country map.

These images are used by a ZClass (Base classes: ZCatalog Aware, Object 
Manager) to display a hotel web page, with info about this hotel.

Authorised users are supposed to create this hotel instance.

I created a Hotel_add_form:

<HTML>
<BODY>

<p><h2>Here you can upload hotel logo and maps into the hotel 
file.</h2></p>

<form action="map_add" method="post"
enctype="multipart/form-data">
<p><b>Logo</b></p>
<input type="hidden" name="logo_id" value="logo26"> 
<p>Title: <input type="text" name="logo_title"> </p>
<p>File: <input type="file" name="file"></p><br>
<p><b>City map</b></p>
<input type="hidden" name="citymap_id" value="map26"> 
<p>Title: <input type="text" name="citymap_title"> </p>
<p>File: <input type="file" name="file"></p><br>

<input type="submit">
</form>
</BODY>
</HTML>

and a method map_add

<dtml-call
  expr="manage_addImage(
    id=logo_id, file=file, title=logo_title)">

<dtml-call
  expr="manage_addImage(
    id=citymap_id, file=file, title=citymap_title)">

<p>Thanks for your photo submission.</p>

Unfortunately when I try to use it I get the following error:
