Drupal 4.7.x

Hi.

I have come across something very odd. I have a callback function which is set in the hook_menu function for my module. In the callback, I change the breadcrumb like this:

$breadcrumb = array();
$breadcrumb[] = array('path' => 'competitions', 'title' => t('competitions'));
$breadcrumb[] = array('path' => 'node/'.$node->nid, 'title' => $title);
$breadcrumb[] = array('path' => 'node/'.$node->nid.'/competition/mosaic', 'title' => t('Mosaic'));
menu_set_location($breadcrumb);

Currently I have a site that is on it's last throws. I need to migrate it to another server; however, the problem is that the new server will already have a newer version of PHP, MySQL, and Drupal.
My question is, What do I need to do to migrate my site with the least amount of problems?

Technical info:
- Old Site:
Drupal 4.7.2
MySQL 4.0.21

- New Site
Drupal 5.1
MySQL 5.0.15

Will this create a problem? If so, what needs to be done in order to fix/avoid those problems.

Many Thanks!

Is there a way to have the site map module display the links as absolute links, so instead of /some_page, it would be http://www.somesite.com/some_page? Our SEO guy is quite a stickler for absolute links in site maps and footer links.

Thanks,

I need to put a select input field in my cck content type. How I Can do this? I want a simple select input field...

Thank you in advance

I have recently been asked to administer a Drupal site for one of my clients. Have worked with lots of web sites, content managers, etc. but this is my first experience with Drupal. The site is currently using 4.7. The site is getting lots of bot posts to a form that is emailed for publication orders, and apparently there is a captcha module that might help. The client wants to include a graphic on the page that requires the user to read the characters and type them in. It does not need to be a rotating image, just a feature that will stop most of the bots from posting.
