Question

As you might know, when you create a new project with CI you’ll have to manually enter base url, encryption key in config/config.php. I’m trying to overcome this and is hence looking for a way to read those values from a database instead – making the installation for a customer and the set up time as a whole decrease a lot.

A customer isn’t able to edit a PHP file’s variables, but is most likely able to, with some guidance, enter base url and have a encryption key automatically filled in by the system.

Is there any way to accomplish this?

Of course! Add a hook – post_controller and set these config values through that file.

config/hooks.php

$hook['pre_controller'][] = array(  'class'    => 'MyOtherClass',
                                    'function' => 'MyOtherfunction',
                                    'filename' => 'Myotherclass.php',
                                    'filepath' => 'hooks');

hooks/myotherclass.php

<?

class MyOtherClass {

    function MyOtherfunction() {

        $CI =& get_instance();

        $row = $CI->db->get_where('configs', array('site_id' => 1))->row();

        $CI->config->set_item('base_url', $row->base_url);

    }

}

Basicly you set these values before they’re used in any controller or similiar.
