Module development and code questions

Upon enabling a new module, I am getting this error message:

Fatal error: Cannot redeclare _hilite_get_query_terms() (previously declared in /home/choirgee/public_html/modules/hilite/hilite.module:65) in /home/choirgee/public_html/modules/hilite/hilite.module on line 65

The only place this function appears in my drupal installation is in this module (obviously) at:

line 65

Hi everyone,

I need to query the DB for a field in the profile_values table - but im off to a very bad start :)

How do i find the users uid (or any other identifying factor) - I mean the user how is looking at the page,...

I can see a session id, and i can even see a user->uid but this does not work:

print_r($user)

So, how do i access the currnet users details?

Many thanks

I badly want attachments to be added to comments can anybody help me out with that...

I'm trying to use the walkah's new image module alongside the album module. I installed folksonomy and the rest in a clean install of drupal CVS. However, I get the error

My website at http://www.my-kart.org/web/ seems to parse the page templates and adds a few blank lines which renders an error in the xml feed.

I know I am not providing much info because I do not know what really is the info to provide.

I am running a standard Drupal 4.5 with a number of the distributed modules installed. I do not what is causing the additional blank lines inserted in the page source.

Any general thoughts as to what typically would cause these additional lines to be inserted?

I'm quite convinced that there is the need to setup the visualization of blocks based upon the role. I need to show or not some blocks on a per-role basis. I would like to implement it, but it needs a new block_access table (similar to the node_access one). It should have to be moved into CVS and not be a simple module, I guess...
