- Newbie alert - how to upload multiple images at once with manage_add_image
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: Zope Error Zope has encountered an error while publishing this resource.

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:

[snip] For one, both file form input boxes are named "file". Try naming them "logo_file" and "citymap_file". You could also use records marsalling to eliminate the redundant coding both on the form and map_add: (Not tested) <form action="map_add" method="post" enctype="multipart/form-data"> <dtml-in expr="['Logo', 'Map']"> <p><b><dtml-var sequence-item></b></p> <input type="hidden" name="images.id:records" value="<dtml-var expr="some expr">"> <p>Title: <input type="text" name="images.title:records"> </p> <p>File: <input type="file" name="images.file:records"></p><br> </dtml-in> </form> Then map_add could be: <dtml-in images> <dtml-call expr="manage_addImage(id, file, title)"> </dtml-in> or a python script: for img in context.REQUEST['images']: context.manage_addImage(img.id, img.file, img.title) hth -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>

Then map_add could be:
<dtml-in images> <dtml-call expr="manage_addImage(id, file, title)"> </dtml-in>
or a python script:
for img in context.REQUEST['images']: context.manage_addImage(img.id, img.file, img.title)
never saw that before... cool :-) Chris
