Module development and code questions

I'm working on our breadcrumbs this morning, and would like to find the node ID of the referring page.

We are using url aliases, so for instance on this page: http://www.realself.com/laser_resurfacing_for_facial_skin_rejuvenation.html

I'd like to be able to see what node ID referred in, and provide that back to users as a breadcrumb.

I just installed flexinode on 4.7.0b6. How do I get the author field to show up? There is no choice to add an author field? It doesn't show up on the node. I need to use the actual default Drupal author field (not just create one) because I am using tagnode to link it to the author's Drupal profile field. Similarly, how do I make the date submitted information show up?

The author and date fields are enabled for all nodes and show up on all other nodes.

Good morning,

I'm trying to figure out how to customize the upload module for use in a module that I'm writing. The main purpose of the module I'm writing is to allow users to upload XML files from their computer. The upload form doesn't need anything other than the file text box and "Attach" button from the upload module. The title and body of the node will be set programatically by the data within the XML file.

My question is this: is it possible to customize the appearance of the upload module? Ideally, I'd like to do the following:

Ok, so I'm developing a block that only shows when viewing a user's profile.

If it's the users' own profile, it says "You have...." and runs a query based upon that user's users.uid field

If someone is viewing another user's profile, it will say " has..." and run a query based upon the viewed profile's users.uid field.

I can load a logged in user's users.uid field, but how do I get the field of the user who's profile is being viewed?

thanks!

Hi,
I am attempting to make it so that my users can upload an unlimited number of files when they purchase a product from the website. Any ideas? I am thinking I can just copy and paste the correct lines from the upload.module to the store.module.

Thank you in advance for any help!
