    ### Canonicalize codeigniter URLs

    # If your default controller is something other than
    # "welcome" you should probably change this
    RewriteRule ^(index(/index)?|index(\.php)?)/?$ / [L,R=301]
    RewriteRule ^(.*)/index/?$ $1 [L,R=301]

    # Removes trailing slashes (prevents SEO duplicate content issues)
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.+)/$ $1 [L,R=301]

    ###
    # Removes access to the system folder by users.
    # Additionally this will allow you to create a System.php controller,
    # previously this would not have been possible.
    # 'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php/$1 [L]

    # Checks to see if the user is attempting to access a valid file,
    # such as an image or css document, if this isn't true it sends the
    # request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # Without mod_rewrite, route 404's to the front controller
    ErrorDocument 404 /index.php
</IfModule>

now I need to owerwrite - to _ so the real url will be like this

/my_controller/my_function/my_value1/other_value2/other_value3/value4

how can I do this?

Answer 1

In your config/routes.php file:

You can define this URL:

/my-controller/my-function/(:any)/other_value2/other_value3/value4

As:

$route['my-controller/my-function/(:any)/(:any)/(:any)'] = "my_controller/my_function/$1/$2/$3";

Here, these 3 (:any) means your three params rest url you can use any thing do you.

One more example with simple route:

$route['about-us'] = "aboutus";

Here aboutus is my controller name, and i want to access it as

http://localhost/project/about-us

Than i can use like that.

Side Note: You can get URL values by using uri->segment().
