How to use a variable in: $this->index(); ?

[eluser]mddd[/eluser]
You could also user call_user_func(). Check the php manual for that.
Example:

Code:

// call index() with argument 'hello'
call_user_func('index', 'hello');

// call $this->index with argument 'hello'
call_user_func(array($this, 'index'), 'hello');

// call mymodel->index with argument 'hello'
call_user_func(array('mymodel','index'), 'hello');
