Better URL-Rewrite RegEx for .htaccess0

For a while I've been using the same .htaccess file when I create a new site. It puts 3 variables in the URL (so far i haven't needed more than 3) and uses the clean URL format that is so popular. I don't remember where I got this but I think it's time to update it. I tried to enter a url with a "-" (like "/aug-sept/") and it tried looking for the real file, and my script didn't catch it. It also broke with "/aug_sept/".

So what i'm looking for is to replace these RegEx strings that are supposed to get the URL variable with some that will accept any normal character in a standard URL. There may also be a better, more flexible way of doing this, but I really don't have the knowledge to understand how to modify it.

BTW, in the code below, variable 4 is supposed to catch anything else in the URL, but that doesn't seem to really work. I would REALLY like this script to work with ANY file OR folders, for example, all of the following would point to the same content:

/contact/email/
/contact/email.php
/contact/email.html
/contact/email.aspx
/contact/email

Does that make sense?

If it's all to point to the same content then simply do this:

RewriteCond   %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule   ^(.+)                             mynewpage.php

That should then make everything, no matter what the slashes contain etc, to point to the php file.  If you are looking for something other than that let us know what you are expecting and the appropriate code can be provided.  Hope this helps.

That sounds kinda right, but i want there to be 3 (or more) variable sent across. For example:

http://www.mysite.com/contact/
works as if it were:
http://www.mysite.com/index.php?action=contact

http://www.mysite.com/contact/email/
works as if it were:
http://www.mysite.com/index.php?action=contact&item=email

My concern with your example is I would somehow have parse through the REQUEST_URI to get what variables appear after domain name, so that I know what content to show the user.

I know a lot of URL Rewrites work similar to this:

http://www.mysite.com/action/contact/item/email/
works as if it were:
http://www.mysite.com/index.php?action=contact&item=email

However, I already want the first 3 items to be set to specific variables.

I hope that clears it up a bit.

Ok, I actually think I might have it figured out.

Thanks for the help.

Hi bdichiara, glad I was able to assist you in some way. The code you posted looks correct.  You may want to impliment at least the first two lines I posted just in case you are trying to load something other than index.  For example you may have a page called help.php which you may want called, without going through index.  The first two lines check to see that help.php exists first, and if it does, go to it, otherwise go to the clauses in your index.php.  Hope this helps.

thanks. I actually did that, but is there a more functional way. For example if they type in help.php, rather than just sending them to the index if the file doesn't exists, can i get it to try to send them to /help/ ? Then my other rules will catch it and it will forward them to my custom 404 if /help/ is not in my database.

Thanks.

Hi Bdichiara,

what I would recommend is putting the help clause before the first index clause:

RewriteRule            /help.php                  /help [L]
RewriteRule            ^$                  index.php [L]


Although your htaccess file will be quite large, you are directing your traffic to various parts of your site based on certain conditions.  

Hope this helps.

The first response sort of worked, however it affected my CSS and IMG (jpeg, gif, etc) files. I think I will just stick to what I posted. The 2nd helped, but to not clutter up my .htaccess file any more than it already is, i'll just accept a 404 for some of those pages. Thanks.
