hello there.

building a site which has content for each section.

urls range from;
/work/
/work/print/
/work/print/folders etc.

however, at any point a user can click on an article so;
/work/article/1066
/work/print/article/1066
/work/print/folders/article/1066

using .htaccess i need to detect when there is 'article' in the url and set some different variables.

RewriteRule ^([a-zA-Z0-9\-]+)/([a-zA-Z0-9\-]+)/([a-zA-Z0-9\-]+)/([a-zA-Z0-9\-]+)/$ 
sets  index.php?level1=$1&level2=$2&level3=$3&level4=$4

but if 'article/([0-9-]+)' is in the url, say /work/print/article/1066 return index.php?level1=$1&level2=$2&articleID=1066

basically the amount of levels will always be different but i'd like to return those as needed. another example would /work/print/folder/archive/article/1066 return

index.php?level1=$1&level2=$2&level3=$3&level4=$4&articleID=1066

any help appreciated! Dan
