No database selected error in CodeIgniter running on MAMP stack
- by Apophenia Overload
First off, does anyone know of a good place to get help with CodeIgniter?  The official community forums are somewhat disappointing in terms of getting many responses.
I have ci installed on a regular MAMP stack, and I’m working on this tutorial.  However, I have only gone through the Created section, and currently I am getting a No database selected error.
Model:
<?php 
class submit_model extends Model {
    function submitForm($school, $district) {
        $data = array(
            'school' => $school,
            'district' => $district
        );
        $this->db->insert('your_stats', $data);
    }
} 
View:
<?php $this->load->helper('form'); ?>
<?php echo form_open('main'); ?>
    <p>
        <?php echo form_input('school'); ?>
    </p>
    <p>
        <?php echo form_input('district'); ?>
    </p>
    <p>
        <?php echo form_submit('submit', 'Submit'); ?>
    </p>
<?php echo form_close(); ?> 
Controller:
<?php
class Main extends controller {
    function index() {
        // Check if form is submitted
        if ($this->input->post('submit')) {
            $school = $this->input->xss_clean($this->input->post('school'));
            $district = $this->input->xss_clean($this->input->post('district'));
            $this->load->model('submit_model');
            // Add the post
            $this->submit_model->submitForm($school, $district);
        }
        $this->load->view('main_view');
    }
} 
database.php
$db['default']['hostname'] = "localhost:8889";
$db['default']['username'] = "root";
$db['default']['password'] = "root";
$db['default']['database'] = "stats_test";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci"; 
config.php
$config['base_url']    = "http://localhost:8888/ci/";
...
$config['index_page'] = "index.php";
...
$config['uri_protocol']    = "AUTO"; 
So, how come it’s giving me this error message?
A Database Error Occurred
Error Number: 1046
No database selected
INSERT INTO `your_stats` (`school`, `district`) VALUES ('TJHSST', 'FairFax') 
Is there any way for me to test if CodeIgniter can actually detect the mySQL databases I've created with phpMyAdmin in my MAMP stack?
