simple mod_rewrite help

[n000bie]

Well, I am total new to mod_rewrite and can't grasp the basic. I am trying to convert my url from

 

http://localhost/mysite/activity.php?c_id=1&a_id=28

to

http://localhost/mysite/activity/components/articles

 

this is my htaccess code

 

Options +FollowSymLinks
RewriteEngine On
RewriteRule ([a-zA-z])+/([a-zA-z])\.html$ activity.php?c_id=$1&a_id=$2

 

It is not working, can anyone tell me what I am doing wrong.

 

Thanks

a.) What seriously makes you think your current rule is remotely close. Even without any understanding of mod_rewrite it should be fairly obvious that a RewriteRule that contains .html is probably not right when neither of the URIs you have listed include .html.

 

b.) A rewrite is impossible given those two URLs, there is no possible way to convert one of those to the other using mod_rewrite.

Thanks, I am new to this mod_rewrite (it is like a nightmare). I will check some tutorials first.

 

anyway thanks for replying

Just to clarify what I meant by it's not possible. A RewriteRule does exactly what the name suggests it 'Rewrites' the URL. This allows you to use either fixed values or values found in the URL that you are rewriting. Since your pretty URL doesn't include the numbers 1 or 28 you can't possibly redirect to that URL (unless you always want the value 1 & 28, but that would seem pretty pointless).
