Codeigniter Route Everything, except these Controllers

2010-06-19T19:21:00.000-07:00

another Codeigniter routes, Codeigniter Route Everything, except these Controllers

There was a recent post on the codeigniter forums trying to get urls like these:
http://yoursite.com/your-slug
This problem could have been easily resolved using this route:

$route['(:any)'] = 'articles/$1';

In this route, all characters after the domain will be passed to the controller, 'article'.

However, the problem was he also had some controllers that he didn't want to use the route for. A quick fix for the route was to use a 'simple' regex using negative lookahead

$route['^(?!controller|controller|controller)\S*'] = "article/$1";

2010-06-16T23:17:00.000-07:00

    RewriteEngine On
    RewriteBase /

    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]

2)edit your application/config.php

$config['uri_protocol'] = "AUTO";

$config['uri_protocol'] = "PATH_INFO";

3) Put to your controller

parse_str($_SERVER['QUERY_STRING'],$_GET);

3)start using $_GET or

$this->input->get('input');

codeigniter callback function to check valid username or email

2010-06-11T00:57:00.000-07:00

this post are from here http://scottblaine.com/form-validation-callbacks-and-private-functions

If you’re familiar with CodeIgniter you probably know about callbacks within form validation. Callbacks allow you to do your own validation of fields. For example, if you want to verify if a username is unique then you could create a username_check function to validate the field. You add the callback rule like this:

1 2	$this->form_validation->set_rules( 'username', 'Username', 'trim\|required\|callback_username_check' );

And then create a matching function like this:

function username_check( $username )
{
  // some code
}
?>

However, as this is currently implemented someone could access your function as a page at a URL like example.com/index.php/login/username_check/ if they guessed the function name. While that may not have any ill side-effects, it’s probably just as well if no one can access the function besides you.
In come private functions for controllers, which allow you to create a function like this:

function _utility()
{
  // some code
}

And if you try to access the function via a URL, like example.com/index.php/login/_utility/, you’ll get a 404 (page not found).
You probably see where I’m going with this. If you create your callbacks as private functions, no one will be able to access the callbacks as pages. It’s quite simple to do. You add an underscore before your callback function name:

function _username_check( $username )
{
  $valid_username = TRUE; // You would perform some kind of check on the field here
 
  if ($valid_username == FALSE)
  {
    $this->form_validation->set_message('_username_check', 'The username you have provided is not valid.');
    return FALSE;
  }
  else
  {
    return TRUE;
  }
}

And then add an underscore in your callback rule (note the two underscores after callback):

1 2	$this->form_validation->set_rules( 'username', 'Username', 'trim\|required\|callback__username_check' );

Done!
