I uploaded the code to the server. It started the homepage correctly . But when I press any link , I get 404 not found error. I discovered that I need to add index.php to my url for it to work. so it will be like that:
mydomain.somee.com/myWebsite/index.php/anotherPage
When I was working locally using Xamp as a server, I didn't get any of those problems. I got those problems after I uploaded the website to some.com which apparently doesn't use .htaccess file (editing or removing has no effect).
How to add this index.php automatically and hide it from the user?
I didn't change any of the system files or the htaccess please tell me if you need anymore files or description.
You need to redirect all your all pages through index.php file but remove it from URL.
Write below rules in your root .htaccess
file:-
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L]
OR
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1 [L,QSA]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s(.*)/index\.php [NC]
RewriteRule ^ %1 [R=301,L]
To understand, How htaccess rules are working, This link will help you :)
Hope it will help you :)
