Module development and code questions

Has anyone ever created a basic AJAX module for a rotating banner? I know Joomla has one, but I could not find anything for Drupal. I would like to find something similar to what you see at this site http://www.phpied.com/ajax-banner-rotation/. I'm very new to Drupal, and I don't have the necessary skills to create a module on my own, but if someone could point me in the right direction or assist me in creating such a module, that would be great.

Hello,
I saw this information on the form API : Adding your own extra _submit or function using hook_form_alter

Does anyone has an example of this?? I've tried to implement it on my own module but I guess I'm not doing it right.

Thanks for your help,
MP.

Hello, all.
I found this module and i must say that it rocks. It is also pretty easy to add new buttons with different actions... (i am a dummie in programing).

But there i have a problem and i am quite sure that it can be solved.
There is a button to add a link. You get a popup to enter a link and then it gives a html code in the text box.

Now, i have an overlib in my site and a code of normal link with overlib included is like that:

I downloaded the CountdownTimer module and installed it as per the instructions (at least I think). I activated the module, updated the database, added a new block and in the block body I put this:

<?php 
drupal_add_js('countdowntimer/timerjs');
?>
<b>Thanksgiving is in</b>
<span id="TG1" class="countdowntimer">2007-11-23 20:30:00</span>

And it does absolutely nothing. Just sits there. I wish I had a dog this obedient LOL
Can someone help me please?
Thanks

I'm thrilled to have found the Views module. It solves a few headaches I've been having trying to learn all of drupal in one go.

I'm messing with some content and I want a very limited view in a block (I only want title and body) only View type "List View" and "tables" lets you limit fields so I'm going with List View as I don't want tables. The thing it adds content as Unordered lists, thus creating indents and bullets where I don't want them.

Hi,

I've found the PHP code snippet to display tags by category:

drupal_set_html_head('<style type="text/css">@import url('.drupal_get_path('module','tagadelic').'/tagadelic.css);</style>');
$vocs[] = 1; //  id of the vocabulary of which you want to display a tag cloud
$output = theme('tagadelic_weighted',tagadelic_get_weighted_tags($vocs));
print $output;

However, some of my vocabularies are used by different content types. I would like to display the tags by content type.
