[development] links

[Ashraf Amayreh]

Hello all,

Don't know if this is the best place for this, so if it's already discussed
elsewhere, I'll be thankful if you could point me to the URL cause I
couldn't find anything myself. I'm really having a tough time when creating
URLs to other parts of a Drupal site. Especially when I'm using clean URLs
and even more when I have Drupal as a subfolder like
http://example.com/mydrupalsite (in which case the internal node page could
be something like http://example.com/drupal/node/5)

As far as I've noticed, there are three cases of referencing, this is how I
do it, but I'm positive that there's something wrong or else I wouldn't get
broken links and/or images when I toggle clean-urls on and off and when I
have my site as a domain opposed to a subfolder:

1. Referencing another page, in this case I use l() or url() with relative
paths to get the link
2. Referencing a file in the themes folder in which case I use src="<?php
print path_to_theme().'/images/whatever.gif';?>
3. Referencing a file in the files folder in which case I use href="<?php
print file_directory_path().'/whatever.zip';?>

The main headache cause is the second one. If I have clean URLs on and the
site as a domain (http://example.com/) then the paths are wrong on node
pages. Although this may be a bug or something, I need to know the standard
way of referencing any and all paths before I jump to conclusions. Would be
grateful if someone could shed the light on this :-)
