Custom SEO URL of Product page in opencart 2.x - php

Question

I am looking for some help on writing custom dynamic SEO URLS for my product and category pages in opencart 2.x
I want to achieve www.example.com/my-keyword/product-name-keyword/ and for category www.example.com/my-cat-keyword/cat-name-keyword/
I tried modifying the code in (/catalog/controller/common/seo_url.php) as below and the URL is being generated in the front-end but when I click on the product name / image it gives 404.
if ($query->num_rows && $query->row['keyword']) {
$url .= '/product/' . $query->row['keyword'];
unset($data[$key]);
}
Here is my htaccess.
# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.
# 2. In your opencart directory rename htaccess.txt to .htaccess.
# For any support issues please visit: http://www.opencart.com
Options +FollowSymlinks
# Prevent Directoy listing
Options -Indexes
# Prevent Direct Access to files
<FilesMatch "(?i)((\.tpl|\.ini|\.log|(?<!robots)\.txt))">
Order deny,allow
Deny from all
</FilesMatch>
# SEO URL Settings
RewriteEngine On
# If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/
# RewriteBase /
RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L]

### Additional Settings that may need to be enabled for some servers
### Uncomment the commands by removing the # sign in front of it.
### If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that.
# 1. If your cart only allows you to add one item at a time, it is possible register_globals is on. This may work to disable it:
# php_flag register_globals off
# 2. If your cart has magic quotes enabled, This may work to disable it:
# php_flag magic_quotes_gpc Off
# 3. Set max upload file size. Most hosts will limit this and not allow it to be overridden but you can try
# php_value upload_max_filesize 999M
# 4. set max post size. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value post_max_size 999M
# 5. set max time script can take. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_execution_time 200
# 6. set max time for input to be recieved. Uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields
# php_value max_input_time 200
# 7. disable open_basedir limitations
# php_admin_value open_basedir none

This is the only code you have to update or any else which faces this kind of problem (mostly)
# If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/
# RewriteBase /
uncomment this line and add your Opencart path if you have any and you have (i checked in your link). So it will be
Rewritebase /projects/bnw-collections/alpha/
and rename your htaccess.txt to .htaccess . Hope this will help.
