Module development and code questions

Not sure if this is an installation problem, an upgrade problem or a module problem . . .

Is there a simple way to implement a registration forms to the events? In contrast to RSVPs I'd like not to invite people to my event, but, first, let them find my event and by filling in the registration form, which would collect additional to user's profile data, apply for the invitation to the event. Then I, based on their submitted data, could send them RSVP.

If anyone could help be debug this situation, I would greatly appreciate it. I'm getting 3 error messages any time I go to a page with node/add in the path. I've modified some existing modules ... adding an additional node_load call or two, and I think it stems from that, but I can't track down the root cause of this problem. Is there any way to identify the code that was calling these functions? Any help would be GREATLY appreciated.

xajax is an open source PHP class library that allows you to easily create powerful, web-based, Ajax applications using HTML, CSS, JavaScript, and PHP. (from http://xajax.sourceforge.net/)

It has a nice and straightforward implementation. It's still in alpha but that should be enough for most purposes.

So, here's a short howto for your own modules, f you like to implement some ajax stuff.

1. Download the class and place it into your module directory

2. Include it into your module file

 require_once('inc/xajax.inc.php' ); 

3. Write the code
Your website should do something when the user clicks the button ;)
We just take the function 'my_function'.

// place this into your php code
function my_function() {
  // code comes later
}

4. Register your functions
Place the following code into your [module_name]_menu() function ( What's this?)

    // initialise xajax
    $xajax = new xajax();
    
    // register functions for ajax
    $xajax->registerFunction("my_function");
    
    // include javascript in html header
    drupal_set_html_head($xajax->getJavascript()); 

    // let xajax process ajax requests
    $xajax->processRequests();

5. Write your javacript code
Wrong ;). We are not required to write any javascript code. Xajax is doing the dirty work for us.

Hi,
I'm trying to limit access to users, based on a custom addition to the user object, a userstatusid.
If the userstatusid is not 0, the user isnt allowed to log in normally, they need to be redirected to one of a number of pages
(we have a complicated signup and verification process, as well as various other user states which requre the user to fill in a form before they can continue).

I've implemented hook_user so that when the user logs in, i check their status, and if its not 0, i call a function. This function should be able to prevent them from accessing any part of the site except a particular page (which is different for each ID)

This is where i have the problem:
if i call user_logout, i have no control over the page they are redirected to. Also their user object is lost so even if i did recirect them, the destination page doesnt know who they are.

if i do a simple redirect, they're still logged in and can just click a link and avoid my destination page.

There are too many states for me to set up a different role for each one, it needs to be something i do at login time, preferably while having full access to the $user object

Basically, once i've verified username and password through the standard login form, i want to know how I can redirect the user, whilst also preventing them from simply returning to the site.

I don't mind if i have to pass the userid manually, such as by redirecting to /somepage/$userid, but i do want the new page to be themed
