Hi guys

I'm having problems with Ajax and the form api. I have a module that uses Ajax to generate content dynamically into a div!

My module structure looks like this

Module-> friends.module - friends.pages.inc
its also holds a directory called inc which has the following file friends.api

Now I have my main function that does this:
function friends_default() {
drupal_set_html_head('

window.onload = function() { friendsoptions(\'?q=friends/showfriends\', \'friends_options_box\') ; }

');
return t('

');
}

When clicking the on Invite A Friend it calls the following function from friends.pages.inc

function friends_invite_form() {
global $user;
$path = drupal_get_path('module', 'friends');

require_once($path .'/inc/friends.api.inc');
print friends_invite_form();
}

function friend_invite_form(){
global $user;

$form['from'] = array(
'#type' => 'item',
'#title' => t('From'),
'#value' => t("$user->name <$user->mail>"),
);
$form['send_to'] = array(
'#type' => 'textfield',
'#title' => t('To'),
'#description' => t("(use commas to separate emails)"),
'#required' => true,
);
$form['message'] = array(
'#type' => 'textarea',
'#title' => t('Message'),
'#rows' => 4,
'#description' => t("(optional)"),
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t("Invite"),
);

return $form;

};

Now the problem I'm having is that it renders the form properly but when submit my form it escapes the div and goes back to printing the form.

Does anybody know a workaround for this. I'm planning on releasing this as an open source module for drupal as the current friend module is cool but is lacks allot of functionality.

Instead of print ...

The problem is not with print, I can do this with
friend.pages.inc

function friends_invite() {
global $user;
$path = drupal_get_path('module', 'friends');

require_once($path .'/inc/friends.api.inc');
$form = drupal_get_form('friends_invite_form');
print $form;
}

The problem lies with the submitting and validating function when I submit the form it escapes the div and displays the function friends/invite
into the menu. I'm loading the function friends_invite() into a div which calls a url ?q=friends/invite and prints the form and when I submit it kicks out of the div and goes back to the menu ?=friends/invite which just prints the the form!

I have a module that is using css to display tabs like on my default page like this:
Friends| Whos Online| Requests | Invite A Friend

Now I use AJAX to generate content and it displays into a div. The content is controlled by drupal function and menus
I.E Invite A Friend -> Menu - friends/invite from friends.module ->Function - invite friends_invite() from friend.pages.inc

Menu friends/invite the loads into a div on ?q=friends menu with ajax

the friends invite function looks like this now:

function friends_invite() {
global $user;
$path = drupal_get_path('module', 'friends');

require_once($path .'/inc/friends.api.inc');
$form = drupal_get_form('friends_invite_form');
print $form;
}

which loads this into the div from friends/inc/friends.api

function friends_invite_form($form_state) {

global $user;

$form['#redirect'] = array('friends', 'destination=friends');

$form['from'] = array(
'#type' => 'item',
'#title' => t('From'),
'#value' => t("$user->name <$user->mail>"),
);

$form['send_to'] = array(
'#type' => 'textfield',
'#title' => t('To'),
'#description' => t("(use commas to separate emails)"),
'#required' => true,
);

$form['message'] = array(
'#type' => 'textarea',
'#title' => t('Message'),
'#rows' => 4,
'#description' => t("(optional)"),
);

$form['submit'] = array(
'#type' => 'submit',
'#value' => t("Invite"),
);

return $form;

}

Now Everything displays fine but when submitting the form instead of displaying the error on ?q=friends it jumps to my form rendering function ?q=friends/invite/

Is there a way I can redirect the errors and submission to display on ?q=friends
