Multiple mod rewrites in .htaccess - .htaccess

Question

I want the following rules but I don't seem to get the right setup.
<domain>/training-courses/
both with or without the slash at the end it should go to:
<domain>/?index.php?page=training-courses
and for each variable extra after this I want it to behave like this:
<domain>/training-courses/success/another-value/and-yet-another/
to
<domain>/?index.php?page=training-courses&val1=success&val2=another-value&val3=and-yet-another-value
If it's not possible to have the option for unlimited leading variables, i'd like to have at least 2 variables after the page variable
Is this possible? and how do I get this sorted out?
I have this so far:
RewriteEngine On
RewriteRule ^test/([^/]*)/$ /test/index.php?pagina=$1&val1=$2
RewriteRule ^test/([^/]*)$ /test/index.php?pagina=$1&val1=$2
RewriteRule ^test/([^/]*)/([^/]*)/$ /test/index.php?pagina=$1&val1=$2
RewriteRule ^test/([^/]*)/([^/]*)$ /test/index.php?pagina=$1&val1=$2
RewriteRule ^test/([^/]*)/([^/]*)/([^/]*)/$ /test/index.php?pagina=$1&val1=$2&val2=$3
RewriteRule ^test/([^/]*)/([^/]*)/([^/]*)$ /test/index.php?pagina=$1&val1=$2&val2=$3

Answer 1

You're quite correct, you can't handle unlimited variables as sub-folders in the way you would like to, mod_rewrite just doesn't support it.
However, in answer to your first problem, to make the trailing / optional, change your rules to the following:
RewriteRule ^test/([^/]*)/?$ /test/index.php?pagina=$1
RewriteRule ^test/([^/]*)/([^/]*)/?$ /test/index.php?pagina=$1&val1=$2
RewriteRule ^test/([^/]*)/([^/]*)/([^/]*)/?$ /test/index.php?pagina=$1&val1=$2&val2=$3

Answer 2

After hours and hours of struggeling it just WON'T work. Since unlimited variables just isn't supported I'm ok with two variables besides the page (pagina). What I have now is this:
RewriteEngine On
RewriteRule ^(test/images|test/css|test/js|test/lib)($|/) - [L]
RewriteRule ^test/(.*)/(.*)/(.*)/ test/index.php?pagina=$1&e=$2&t=$3
RewriteRule ^test/(.*)/(.*)/(.*) test/index.php?pagina=$1&e=$2&t=$3
RewriteRule ^test/(.*)/(.*)/ test/index.php?pagina=$1&e=$2
RewriteRule ^test/(.*)/(.*) test/index.php?pagina=$1&e=$2
RewriteRule ^test/(.*)/ test/index.php?pagina=$1
RewriteRule ^test/(.*) test/index.php?pagina=$1
None of the RewriteRules work except from the first one which excludes folders from the other rewriterules. With working I mean it will actually redirect the URLs to index.php but I can't get the values in PHP through ie $_GET['pagina']
Strange thing is this WILL work, though is way too limited for my liking:
RewriteEngine On
RewriteRule ^(test/images|test/css|test/js|test/lib)($|/) - [L]
RewriteRule ^test/(.*)/ test/index.php?pagina=$1

Answer 3

I would like to come back to my own question and answer it. For a while now i'm using exactly what I want.
First off I have this in my htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
# existing folders or files
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.* - [L]
# non-existing folders or files
RewriteRule ^(.*)/? index.php?p=$1 [L]
</IfModule>
This allows to access real files at all times. If the path does not exist it will pass the entire path to index.php.
In index.php I have the following code at the top:
// Split the URL in all its components
$request = parse_url(strip_tags($_GET['p']));
// Only take the path without any leading slashes
$path = rtrim($request['path'], '/');
// Split each variable from eachother
$path_array = explode("/", $path);
if(count($path_array)){
// By default I select the first variable as the page I will include later on
$page = $path_array[0];
// Each other variable I will pass as $val[#nr] starting with 1. Just to be sure I'm going to strip tags and slashes
for($i=1;$i<count($path_array);$i++){
$path_array[$i] = strip_tags($path_array[$i]);
$path_array[$i] = stripslashes($path_array[$i]);
$val[$i] = $path_array[$i];
}
}
else{
// If $path_array doesn't contain multiple variables lets assume $path will contain the $page
$page = $path;
}
// If $page is empty let's take on the default page to include later on
if(empty($page)){
$page = "home";
}
if(file_exists($page . ".php")){
include($page . ".php");
}
else{
echo "Page " . $page . ".php does not exist.";
}
To give you some examples of the posibilities:
domain.com/ will include home.php
domain.com/product/ will include product.php
domain.com/product/298833/ will include product.php and parse 298833 as $val[1];
domain.com/product/298833/purple-candle will include product.php and parse 298833 as $val[1]; and purple-candle as $val[2]; Notice the leading slash not being included. It does not matter.
I'm open for improvement or tips in general. For now this is definitely the answer I was looking for back when I asked this question.
