php - Turn text after slashes into variables with HTACCESS

Question

I need to pass 3 variables with a URL but using slashes. So for example I would use this URL:

http://www.example.com/variable1/variable2/variable3

I have this in my HTACCESS which allows the text after the first variable to be passed but I can't get the other two to come through, even if I add &$2

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule /?([A-Za-z0-9_-]+)/?$ process.php?width=$1&height=$2 [QSA,L]

Any links or help would be great

Answer 1

You are only capturing one variable in your rewrite rule.

You need something like:

RewriteRule ^([A-Za-z0-9_-]+)/([A-Za-z0-9_-]+)/([A-Za-z0-9_-]+)/?$ process.php?width=$1&height=$2&third=$3 [QSA,L]

or, a bit shorter:

RewriteRule ^([w-]+)/([w-]+)/([w-]+)/?$ process.php?width=$1&height=$2&third=$3 [QSA,L]

(the w word character includes letters, digits and underscores)

I have made only the ending slash optional so this rewrite rule would only do something if there are exactly 3 variables.
