form with confirmation (sometimes)

[Lluís Forns Puigmartí-2]

I have a form to allow deleting some variables. If the deleted item is
'empty' it should be possible to delete it without any problem; but
full items should have a 'confirmation' step before deleting them.

I have read http://drupal.org/node/387674 and
http://drupal.org/node/385640; but in my case I need to pass an array
to the confirmation form, and I think it has to be an easier way to
allow a "Are you sure you want to do this?".

Any hint is welcome.

Look at node module, specifically node_admin_nodes() and  
node_admin_nodes_validate() and node_admin_nodes_submit() which are  
all found in node.admin.inc in Drupal 6. It provides this same  
functionality - it only shows a confirmation form if the operation is  
to delete nodes.

I have taken a look to these funcions but I cannot see how
$form_state['rebuild'] = TRUE;
make confirmation appear.

BTW, I don't like the node.module implementation of config_form on
delete workflow.

Even worst in comment.module, they do the same stuff accessible directly
to $_POST superglobal.

They should properly do this using a multistep form, I.E. by accessing
variables in the $form_state and playing with the $form_state['rebuild']
option, which they are not apparently doing.

The $form_state['rebuild'] forces the form API to rebuild the same form,
using the same processing function, but instead of giving a empty
$form_state, it gives a full filled array with values you set into.

Somehow, in validate then submit, you do a $form_state['delete'] =
array(<your nid's here>), then, in you processing form function, you can
catch the $form_state if not empty (and filled with your 'delete'
attribute), then you can use a if statement to build a different form
(in your case, a simple config_form(), with an altered '#submit' which
will be the real delete operation submit callback).

Hope it helps.
