从数据库读取CodeIgniter配置值，而不是配置文件 [英] Reading CodeIgniter config values from database instead of config file

问题描述

您可能知道，当您使用CI创建新项目时，必须在config / config.php中手动输入基本URL，加密密钥。我想解决这个问题，因此希望能够从数据库 中<读取 这些值。

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.

客户无法编辑PHP文件的变量，但最常见的是

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.

有没有办法做到这一点？

Is there any way to accomplish this?

推荐答案

当然！添加 hook-post_controller 并通过该文件设置这些配置值。

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);

    }

}

这些值在用于任何控制器或类似操作之前。

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