Module development and code questions

HOWTO: Hide or display a form element using javascript?

Hi,

I already installed the ldap modules previously and the ldap_module on others drupals with php5 with no problem.

Hi,
I've installed the event module in a private drupal site. When I say private, it means that only authenticated members can have access to it. The Event module offers the possibility to subscribe to the calendar with a webcal link. However, this operation is performed in anonymous mode, I think, and I receive an access error mode. Is there a way to circumvent that?

Fatal error: lmo_admin_common() [function.require]: Failed opening required '/init.php' (include_path='.:/php/lib/php/') in /web/htdocs/www.hopfrog.it/home/modules/lmo/lmo.module_cmn.inc on line 91

Why?

Hi,

I have a multi-sites installation, I need to retrieve the sub-directory of drupal installation from a module I have created.
Is there a constant to get the current installation directory (~drupal/sites/my_site1/ for instance), since I need to get information from settings.php file.

Thanks for your support.

I've d'loaded and installed the lightbox module (with scriptculaous/prototype js), but It doesn't want to seem to work at all. I followed the readme, and when I try to create a lightbox link, when I click the link, it just opens the actual .jpg page in a seperate window instead of in the lightbox div.

Any ideas what may be wrong?

Much thanks.
