How to setup dynamically database file in cakephp 3?

I want to configure database from front-end while cakephp project first loading like as cms(wordpress,joomla).

Your help will be highly appreciated. Thanks in advance. Looking forward from anyone who expert in this issue.

You can define as many connections as you want in your configuration file. You can also define additional connections at runtime using Cake\Datasource\ConnectionManager::config() . An example of that would be:

use Cake\Datasource\ConnectionManager; ConnectionManager::config(‘default’, [ ‘className’ => ‘Cake\Database\Connection’, ‘driver’ => ‘Cake\Database\Driver\Mysql’, ‘persistent’ => false, ‘host’ => ‘localhost’, ‘username’ => ‘my_app’, ‘password’ => ‘sekret’, ‘database’ => ‘my_app’, ‘encoding’ => ‘utf8mb4’, ‘timezone’ => ‘UTC’, ‘cacheMetadata’ => true, ]);

Configuration options can also be provided as a DSN string. This is useful when working with environment variables or PaaS providers:

ConnectionManager::config(‘default’, [ ‘url’ => ‘mysql://my_app:sekret@localhost/my_app?encoding=utf8&timezone=UTC&cacheMetadata=true’, ]);

When using a DSN string you can define any additional parameters/options as query string arguments.
