In Drupal 6, there are several problems with having 2 forms on a page using the same form id. You will probably need to implement hook_forms() to create a new form id (e.g., 'YOURMODULE_user_login_block_premium') that maps to the 'user_login_block' callback (see http://api.drupal.org/api/function/user_forms/6 for an example of how this is done). Then you can drupal_get_form() the two forms using different ids, and hook_form_alter() them differently based on the $form_id. I'm hoping Drupal 7 fixes the remaining bugs with multiple instances of the same form on a page. I'm not sure what all of them are yet, but for starters: http://drupal.org/node/766146. Alex.

Hi Earnie,
Thanks for the answer and that's one of the things to do, but my problem at the moment with that path is that in hook_form_alter there doesn't seem to be anything that I can use to identify which block it is. Am I missing something obvious?
If there is nothing in the $form then what I think I actually want to do is use some code to generate the form and as I have access to the $form array to put in my own validation rule or hidden $form element or whatever to distinguish between the different blocks. So I'm trying to generate the user_login_block myself so I can alter the $form array but can't get it to work. In my block code if I call drupal_get_form('user_login_block') for the block content everything is fine but I can't alter the form object. So I'm trying to do the same steps as drupal_get_form, i.e. the code below and the user login block displays but there is a bunch of stuff missing from it so it doesn't actually submit.
Am I making this harder than I need to for what I'm trying to achieve?
Regards, Anthony.
$form_state = array(); $form = drupal_retrieve_form('user_login_block', $form_state); drupal_prepare_form('user_login_block', $form, $form_state); $block['content'] = drupal_render_form('user_login_block', $form);

Hi, Does anyone have ideas on how to implement the function in the subject? Basically I want a page with two login blocks, one for general users and one for premium users. I've used multiblock to get the two blocks up there but I need the two different blocks to work different for the different user types. That is if a general user tries to login on the premium login it fails and vice versa. Is there any easy way to do this or do I have to recreate my forms manually?
You don't need to start from scratch but you do need to code using hook_form_alter to add the appropriate form elements and also a hook_user to capture the user operations and operate on the appropriately.
