apache url rewrite with multiple parameters keep parameter=value

Question

I have a url like this

fullarticle.php?sID=3&ssID=21&id=1496
sID = category (Forums, entertaiment, news, sports etc)
ssID = sub category (businnes, health, crime, etc)
id = article id

My goal is to make that url look like this

fullarticle/News/Crimes/title

I've tried this at .htaccess:

RewriteRule ^([^/]+)/([^/]+)/([^\.]+)/([^\.]+)/([^\.]+)/([^\.]+)$ fullarticle.php?$1=$2&$3=$4&$5=$6 [L,NC,QSA]

another one

RewriteRule ^/([a-zA-Z\+]+)/([a-zA-Z\+\-]+)/([0-9]+)$ fullarticle.php?sID=3&ssID=21&id=1496

And some other with no luck.

How can I write a rule/condition to accomplish that? If there is an easier way to do this I am open to suggestions.

Thanks for taking the time to look into this.

"I have a url like this" ... "to make that url look like this" - to make it look like that you first need to change the URL in your application to make it look like that. Have you already done that? (Apologies, but I have to ask, since so many ask the same question, without doing this first step, expecting to do the whole thing in .htaccess.) — MrWhite

no worries. in my php i generate urls like fullarticle.php?sID=3&ssID=21&id=1496. I have tried many RewriteRules trying to make it look like fullarticle/news/crime with no luck. stackoverflow.com/questions/16816342/… mod-rewrite-cheatsheet.com statichtml.com/2010/mod-rewrite-baseon-on-query-string.html — tito_santana

(Your PHP should be generating the URLs in the format you want them to look to your users.) How would you intend to convert /news/crime to sID=3&ssID=21 etc.? Where do you get the numeric ID's from? — MrWhite

I don't want confrontation but I believe that is what RewriteRule is for. The problem is that all the rules/condition I tried still don't work. Any constructive reply would be appreciated. — tito_santana

You could try RewriteMap to map from names to numeric ids. But this requires to set up such a map before, e.g.

categories.txt:

news 1
sports 2
entertainement 3

subcategories.txt:

crime 11
baseball 21
football 22
movie 31

titles.txt:

rewrite-rules-solved 83
stackoverflow-rocks 77
you-are-the-greatest 27

and then use that in a RewriteRule

RewriteMap cat "txt:/path/to/categories.txt"
RewriteMap sub "txt:/path/to/subcategories.txt"
RewriteMap title "txt:/path/to/titles.txt"

RewriteRule ^/(.*?)/(.*?)/(.*)$ fullarticle.php?sID=${cat:$1}&ssID=${sub:$2}&id=${title:$3} [L]

Instead of txt files, you can also use prg or dbd mappings. This would allow to retrieve the name to id mapping from a program or an SQL select statement. See the RewriteMap manual for more details.

Thanks Olaf. That actually works. However; it is going to be lot of work for maintenance. Our Categories, sub Categories, and title come from the database and keeps on adding/changing. I was thinking into converting the urls to fullarticle/News-3/Crimes-21/title-1496 and get the values from it. I am the process of separating News and 3, Crimes and 21, etc. Thanks again

If you have these already in a database, you could try a prg or dbd mapping instead of a txt file. See updated answer.

Thanks for your time and suggestions Olaf. I appreciate that. However; I needed this working right away. I promise thought that I will look into prg or dbd which are topics out of my league at this point but looks promising for future reference.

What I ended up doing was build my dynamic URLs like this:

fullarticle/3/21/1496/title.html

where 3 = category, 21 = sub category and 1496 = title id

My rewrite looks like this:

RewriteRule ^fullarticle/([^/]+)/([^/]+)/([^\.]+)/([a-zA-Z0-9-]+).html$ fullarticle.php?sID=$1&ssID=$2&id=$3 [L,NC,QSA]

I am a novice and it only took me 6 hours to figure it out. I am proud of my self!
