[web2py] Re: How to do this? Obviously I need ajax but what's the exact syntax?

[Leonel Câmara]

No not exactly that Ben the images should go in the view too. It might be 
easier to simply use checkboxes next to the images if you guys are having a 
hard time. This way there's no need for hidden fields or javascript.

Lets see if I get this right. In the view, place this:

{{=clickme}}
then in the controller:

for image in imageRows:
clickme.append(TAG.button(IMG(..image..),_type="button", 
_onclick="jQuery('#xID').val('%d');ajax('%s', ['picID'])" \
% (image.id 
,URL('default','functionThatAddsToDatabase',extension='load', 
user_signature=True))) )

calls the function
def functionThatAddsToDatabase():
# get the image id
   image_id=request.vars.picID

Make a form with a hidden input and a submit button. Display all the 
images, add javascript so when one image is clicked it becomes "selected" 
and its id is added to the hidden input (for instance the hidden input can 
store the values comma separated). Submit the form and in your controller 
you should have the selected images in the hidden input's name. You can 
then validate it using something like:

values, error = IS_IN_DB(db, 'pictures.id', multiple=True, 
delimiter=',')(request.vars.hidden_input_name)

Finally after checking error is None insert the values into choices:

for value in values:
db.choices.insert(user_id=auth.user_id, choice=value)
