Question

我已经在常规MAMP堆栈上安装了ci，我正在使用this tutorial。但是，我只浏览了Created部分，目前我收到了No database selected错误。

型号：

<?php 
class submit_model extends Model {

    function submitForm($school, $district) {
        $data = array(
            'school' => $school,
            'district' => $district
        );

        $this->db->insert('your_stats', $data);
    }

}

查看：

<?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(); ?>

控制器：

<?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中

$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";

的config.php

$config['base_url']    = "http://localhost:8888/ci/";
...
$config['index_page'] = "index.php";
...
$config['uri_protocol']    = "AUTO";

那么，它怎么会给我这个错误信息？

A Database Error Occurred
Error Number: 1046

No database selected

INSERT INTO `your_stats` (`school`, `district`) VALUES ('TJHSST', 'FairFax')

Answer 1

尝试将密码留空。

我认为这是WAMP和XAMPP的默认值。它也适用于MAMP。

Answer 2

我假设您（自动）加载数据库类？

仔细检查这个，并检查数据库名称是否正确。

在MAMP堆栈上运行的CodeIgniter中没有数据库选择错误
