htaccess - insert script name into all URL requests - php

Question

I have an application which requires an htaccess file that contains the following:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(tileserver\.php)
RewriteRule ^(.*)$ tileserver.php?/$1 [L,QSA]
But I am getting 404 errors matching the following patterns:
http://107.170.120.88/tileserver/extra5/11/331/794.png
and:
http://107.170.120.88/tileserver/extra5/11/331/796.grid.json
It seems that any URL with the path:
tileserver/extra5/
needs to be instead:
tileserver/tileserver.php/extra5/
but I haven't had much luck writing an htaccess file to fix this.
If I take out the
RewriteCond $1 !^(tileserver\.php)
RewriteRule ^(.*)$ tileserver.php?/$1 [L,QSA]
the base script doesn't work, but then if I add something like:
RewriteRule ^tileserver/extra5/(.*)$ tileserver/tileserver.php/extra5/$1
it has no effect. How do I write this rule?
--- UPDATE ---
Here's the full htaccess:
DirectoryIndex tileserver.php
RewriteEngine on
RewriteBase /tileserver/
<FilesMatch "\.mbtiles$">
Order Allow,Deny
Deny from all
</FilesMatch>
RewriteRule ^(.+).jpeg$ $1.jpg [L]
RewriteRule .* - [E=HTTP_IF_MODIFIED_SINCE:%{HTTP:If-Modified-Since}]
RewriteRule .* - [E=HTTP_IF_NONE_MATCH:%{HTTP:If-None-Match}]
RewriteRule ^tileserver.php - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ tileserver.php?/$1 [L,QSA]
Note that it is sitting in a subdirectory, in which the parent (root) has this htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Which removes index.php from all URLs (for codeigniter). Maybe that's conflicting?

Answer 1

With the datastructure like this:
example.com/tileserver/tileserver.php
and the url for the matching pattern
107.170.120.88/tileserver/extra5/11/331/794.png
which should result in 107.170.120.88/tileserver/tileserver.php?/extra5/11/331/794.png
your .htaccess should look something like this:
#turn on the rewrite engine
RewriteEngine On
#use the as base for your rewrite conditions the following folder
RewriteBase /tileserver
#since we don't want to rewrite the requests pointing directly to this script, leave it
RewriteRule ^tileserver.php - [L]
#if its not a file or a folder rewrite everything to tileserver.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#everything that comes after /tileserver is passed as argument to the php script
RewriteRule ^(.*)$ tileserver.php?/$1 [L,QSA]

Answer 2

I suspect the problem might be the [L] flag.
Instead, try:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(tileserver\.php)
RewriteRule ^(.*)$ tileserver.php?/$1 [QSA]
RewriteRule ^tileserver/extra5/(.*) tileserver/tileserver.php/extra5/$1 [L,QSA]
