How to create routes using the MySQL database

I think arma7x is correct btw.

Why not use the :any command?

Code:

$route['rigatos/(:any)'] = "rigatos/cucuru/$1";.

Now your rigatos controller checks to see if the collected variable is in your database.

Code:

class Rigatos extends CI_Controller {

  public function cucuru($word='')
  {
      // check to see if $word is in the database (or file, or array of acceptable terms, or whatever)
      ....

     // it is, great, do something
     ....

     // it is not, then deal with that
     ....

  }
}

You said

What I want to do is to have the same content of the "cucuru" method also for other methods, without the need to write other methods.

That is a little confusing, but perhaps the curcuru function needs to be in a library, so other functions can call it at will?

Perhaps if you give a little more information about what you are trying to achieve someone can suggest a better way to achieve it.

Best wishes,

Paul.
