Hi,I'm trying to implement the front controller pattern for a simple PHP site, while simultaneously leveraging mod_rewrite for some run-of-the- mill rewriting beforehand as well. Apache 2.2.4 & PHP 5.2.2. My simplified rules in .htaccess at present are as follows:
----- # Rewrite any requests ending with '.htm', '.html' to end with '.php'. RewriteRule ^(.*)\.htm[l]?$ $1.php [NS]# Verify the requested file exists, and if so end by sending the request to our front controller. # The front controller will be injecting the requested page into a layout, so grab the request URI # as it was rewritten just prior to the rewrite to the front controller itself, and stuff it in the
# server environment variable "REWRITTEN_REQUEST_URI".
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.+)$ frontcontroller.php [NS,E=REWRITTEN_REQUEST_URI:$1]
# Serve anything left directly, 404 with Apache's ErrorHandler if not
found, or the like.
-----My issue is that for a request such as "index.html" REWRITTEN_REQUEST_URI ends up being "frontcontroller.php", not "index.php" as I had hoped.
My rewrite log is below. As I understand it the issue is the two phase processing mod_rewrite must do for per-directory context rules as described here: <http://httpd.apache.org/docs/2.2/rewrite/ rewrite_tech.html>. Despite my hopes the nosubreq flag doesn't seem to apply in this special case, and so my variable is being overwritten with the undesired value from the second pass.
I tried a using a conditional rewrite that wouldn't match for the second "frontcontroller.php" pass:
RewriteCond %{REQUEST_FILENAME} !frontcontroller.php
RewriteRule ^(.+)$ - [E=REWRITTEN_REQUEST_URI:$1]
The variable set according to the logs, and was not overwritten on
the second pass, but it wasn't available to my PHP script. I'm
assuming that implies that first pass really is a "fake" one,
environment variables set in it are only scoped private to the first
pass itself?
To get to my question is there any way to capture the rewritten URI part way through the first pass?
A workaround would be to not do the .htm[l] to .php rewriting and the like in Apache, but instead handle it all in my PHP front controller, but I'd rather leverage the existing functionality than duplicate it from scratch. Moving the rewriting to the per-server context is also very undesirable as it prevents use of the pattern by those who don't have access to the server config.
