        }
        
        // THIS CODE I NEED LOAD AUTOMATICALLY
        $this->load->model('registro_paciente/Registro_model');
        $clinicas = $this->Registro_model->obtener_clinicas( );

what you need is a HOOK

http://ellislab.com/codeigniter/user-gui...hooks.html

More specifically, the "display_override" Hook :

Code:

display_override
Overrides the _display() function, used to send the finalized page to the web browser at the end of system execution. This permits you to use your own display methodology. Note that you will need to reference the CI superobject with $this->CI =& get_instance() and then the finalized data will be available by calling $this->CI->output->get_output()

of course, the hook runs on every load of the system, so if you wanna do the "AUTOMATICALLY" part only for that controller, you must condition it by url

Uh... or just use set_value()

No because I need, that the select in the form charged after if generated error.

Search "display_override" in the forums, there's an example of this.

Code:

<?php echo form_dropdown('field_name', $field_options, set_value('field_name')); ?>

Will give you a select field named "field_name", with the options $field_options, and if the form has been posted (form validation failed) the default value will be whatever was selected

thanks!

Last question, a app with login user and permissions per page, where I found?
