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?

    First check the obvious – is there a database stats_test, and can you connect using the details in your config? You may have a problem with user permissions. Also check that you have a line $active_group = 'default'; at the beginning of the database.php file, which says to use those connection parameters.

    By the way, I’d suggest setting $db['default']['pconnect'] to false instead of true. Lots of people have had connection problems using that, particularly if you have other non-CI parts of the website using a regular connection.
