<DIV>Great, Anthony. I suggest that you write up a little snippet page for the Handbooks so it can be found with a search.</DIV>
<DIV> </DIV>
<DIV>BTW, remember the array_unshift technique, because you will need it again, especially if you do any node_form alters. I worked that same one out some time ago and am amazed at how many times I have to get my submit handlers to fire first. I just had to do it again a couple of days ago on the comment_form. So documenting this in the handbooks could save people a lot of time in the future.<BR> </DIV>

Worked it out, will describe what I ended up doing in case it's useful to anyone.<BR><BR>Nancy and Earnie, I was using MultiBlock and the core of the problem for me was that they *don't* change the $form_id so there is nothing to differentiate them. Alex, yep, I'd started to look at hook_forms so your tip was a good kick in the right direction. Lee, by the time I got your email I'd worked it out :)<BR><BR>So as an example, I had to throw away MultiBlock and generate the blocks on my own but it was pretty easy to do. My
application is a timesheet application and there is a role called 'candidate' that needed a separate login. The only real problems I had after getting the hang of all that is for some reason I had to shift my validation function into the first slot (see comments in hook_form_alter) to get it to fire, and if I do a form_set_error(), because the elements are the same name the red error border appears on both, but hey I can live with that.<BR><BR>in my hook_block:<BR><BR>case 'view':<BR>$block['subject'] = 'Candidate Login';<BR>$block['content'] = drupal_get_form('candidate_login_block');<BR>return $block;<BR><BR>Now because 'candidate_login_block' doesn't exist as a function that can be called by drupal_get_form I want drupal_get_form to be called as drupal_get_form('user_login_block') and to make this happen I set up a hook_forms (note, not hook_form) as below:<BR><BR>function timesheet_forms($form_id, $args)
{<BR>$forms['candidate_login_block']['callback'] = 'user_login_block';<BR>return $forms;<BR>}<BR><BR>This all means that in my hook_form_alter I can do:<BR><BR>switch($form_id) {<BR>case 'candidate_login_block':<BR>// $form['#validate'][] = '_timesheet_candidate_login_validate';<BR>// The line above doesn't seem to result in my validation function getting called so had to use the form below.<BR>array_unshift($form['#validate'], '_timesheet_candidate_login_validate');<BR>break;<BR><BR>In my function _timesheet_candidate_login_validate I can do whatever I want to invalidate the form (I called user_load with the entered field and checked its roles). Done.<BR><BR>Thanks,<BR>Anthony.<BR><BR>On 14/05/2010 3:37 PM, Lee Rowlands wrote:<BR>> <BR>> For a decent Hook_forms example look to ubercart’s uc_product, it uses hook_forms to register the ‘add to cart’ forms : http://api.lullabot.com/uc_product_forms<BR>> <BR>> *>* I think the answer
