Having some issues with htaccess mod rewrite - php

Question

Hello everyone wondering if i can pick your brains and il be as descriptive as possible.
So i am trying to create a page that will load a title and category (dynamic from database) based upon the selection that is picked by the user
sitename used as my domain name
So to be a little clearer i have a file and variables named sitename/2017/slot.php?gp=category&sn=title
the category and title are stored in the database for each row what i want to do is make a clean URL to look like this sitename/2017/slot/category/title/
So when viewing the page like this sitename/2017/slot.php?gp=category&sn=title the page loads everything in and displays correctly and the variables are being set as i can see them in my title in the browser tab
my error comes when i use the mod rewrite to make it clean, once the .htaccess has been changed and uploaded and i navigate to the new clean URL sitename/2017/slot/category/title/ it shows me the variables havent been set as they no longer appear in the title tab of the browser and also the page doesnt use my css. Below i have added my htaccess rule, any help and feedback is greatfully appreciated
#change this sitename/2017/slot.php?gp=category&sn=title
#to this sitename/2017/slot/category/title/
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^slot/([a-z-]+)/([a-z-]+)/ slot.php?gp=$1&sn=$2 [NC,L]
just incase here is the php code im using in slot.php i am connecting to my database fine no issues there and after the code below im running a while loop to get out the data for the row the user clicked on
if($_GET['gp'] && $_GET['sn']){
$gp = preg_replace('#[^a-zA-Z-]#i', '', $_GET['gp']);
$sn = preg_replace('#[^a-zA-Z-]#i', '', $_GET['sn']);
}
here is the full code i have in my htaccess
#make custom page not found
#ErrorDocument 404 /filenotfound.php
#stop directory file listing in all folders
IndexIgnore *
#make pages have www. in them
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.org

Options -MultiViews +FollowSymLinks
RewriteRule ^slot/([a-z-]+)/([a-z-]+)/ /2017/slot.php?gp=$1&sn=$2 [R=302]

Answer 1

If your URL starts with 2017 you must include it in your RewriteRule.
RewriteRule ^2017/slot/([a-z-]+)/([a-z-]+)/ slot.php?gp=$1&sn=$2 [NC,L]

Answer 2

You're misusing the ^, which matches the very start of the path (the part after sitename/. That is, a rule starting with ^slot/ will match only sitename/slot/, not sitename/2017/slot/. Your rule should look like this:
#change this sitename/2017/slot.php?gp=category&sn=title
#to this sitename/2017/slot/category/title/
RewriteRule ^2017/slot/([a-z-]+)/([a-z-]+)/ slot.php?gp=$1&sn=$2 [NC,L]

Answer 3

May I join the party?
RewriteRule ^sitename/2017/slot/([a-z-]+)/([a-z-]+)/ /slot.php?gp=$1&sn=$2 [NC,L]
If the sitename the domain name, I will change my answer to :
RewriteRule ^2017/slot/([a-z-]+)/([a-z-]+)/ /slot.php?gp=$1&sn=$2 [NC,L]
Which is almost the same as Dekel's, but not exactly :)

#example.com/2017/slot.php?gp=category&sn=title
#example.com/2017/slot/category/title/
You'll need to disable MutliViews. Near the top of your .htaccess file:
Options -MultiViews
With MultiViews enabled (part of mod_negotiation) /2017/slot is being implicitly rewritten to /2017/slot.php (without any query string paramaters) before your mod_rewrite directives are being processed.
Although it's still not clear where your .htaccess file is located. So, there may still be some work to do... If your .htaccess file is located at example.com/2017/.htaccess then your existing mod_rewrite directives should be sufficient.
However, if your .htaccess file is in the document root (ie. example.com/.htaccess) then you will need to modify your RewriteRule:
RewriteRule ^2017/slot/([a-z-]+)/([a-z-]+)/ 2017/slot.php?gp=$1&sn=$2 [NC,L]
