Question

I am trying to connect to multiple databases in cakephp 3. I have tried many times but all questions and answers are in cakephp 2

Answer 1

I get a solution of my problem. And it's working good. Please refer the below code and comment if I am wrong at any place.

--> app.php

'Datasources' => [
'default' => [
    'className' => 'Cake\Database\Connection',
    'driver' => 'Cake\Database\Driver\Mysql',
    'persistent' => false,
    'host' => 'localhost',
    //'port' => 'nonstandard_port_number',
    'username' => 'your_username',
    'password' => 'your_password',
    'database' => 'tracking_system', // This is my default database
    'encoding' => 'utf8',
    'timezone' => 'UTC',
    'cacheMetadata' => true,
    'quoteIdentifiers' => false,
    //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
],

'db2' => [
    'className' => 'Cake\Database\Connection',
    'driver' => 'Cake\Database\Driver\Mysql',
    'persistent' => false,
    'host' => 'localhost',
    //'port' => 'nonstandard_port_number',
    'username' => 'your_username',
    'password' => 'your_password',
    'database' => 'tracking_system2', // This is my second database
    'encoding' => 'utf8',
    'timezone' => 'UTC',
    'cacheMetadata' => true,
    'quoteIdentifiers' => false,
    //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
 ]
]

--> TodolistsController.php

database name: tracking_system2

table name: todolists

• add this line to your controller

use Cake\Datasource\ConnectionManager;

my TodolistsController.php code is:

execute('SELECT * FROM todolists')->fetchAll('assoc');
    $this->set('results', $results);
    if($this->request->is('post')){
        $connection->insert('todolists', [
            'title' => $this->request->data['title'],
            'description' => $this->request->data['description']
        ]);
        $this->redirect($this->referer);
    }
}
}

--> TodolistsTable.php

addBehavior('Timestamp');
    }
}

That's it.

Thank You...
