I'm writing a script to read a xml file from the last.fm website. I wrote a module to parse the xml into a block.
This is a part of the code:

Is there a way to check and then drop one of two identical values called from a db using php? For example, when calling up the breadcrumbs when multiple parents is enabled, the top level term is called twice into the breadcrumb, once for each parent term. How could I write an addition to the php to check and then drop the second identical value?

Any suggestions or work arounds welcome.

After using paging module realised that when I have comments on page for several pages then I can´t correctly skip to them. _GET Page param duplicates for both pages & comments.

Haven added this to issues, ćos it needs more disscussed and then added.

Q: What you think is the best implementation would be? Currently Iḿ thinking of making the paging module to link to ¨node/1¨, ¨node/1/1¨ (means 2nd node page), ¨node/1/2¨ (3rd), ¨node/1/3¨ (4th) etc. And leaving comment paging as it was.

Is this possible or does it always have to be ordered by ID?

Thanks

Hi All,

I am wanting to have some functionality added to the way Drupal handles the node author value, but as this is a modification of an existing function in Drupal I am not sure if it requires a core hack or if a new module should be developed. In a nutshell what I am wanting is;

1. Ability to set the author value of each node to username, arbitrary text (so authors don't need to have an account to submit content with their name against it) or a defined value (coontents of a "Real Name" field for example) from the profile module.
