I have a cakePHP app with my DB servers configured in the app/config/
database.php file. However, I need to use the get_cfg_var ('mysql.default_host') to get the host name because the client does not want the name hardcoded.
In the /app/config/bootstrap.php file, add a new constant like so:
<?php
// get the default host name set in php.ini
$defaultHost = get_cfv_var('mysql.default_host');
// might want it to try using localhost if get_cfv_var is not set
if(!$defaultHost) {
$defaultHost = "localhost";
}
define("DB_HOST_NAME", $defaultHost);
?>
Then in /app/config/database.php, in the default array (or whatever DB array you are using for production) use the constant:
<?php
// set up the database connection
var $default = array(
'driver' => 'mysql',
'persistent' => false,
'host' => DB_HOST_NAME, // use the default set by get_cfv_var()
'login' => 'username',
'password' => 'password',
'database' => 'database',
'prefix' => '',
);
?>
Hope this helps!

I connect to a remote database from within my symfony2 app with this code
$connectionFactory = $this->container->get('doctrine.dbal.connection_factory');
$conn = $connectionFactory->createConnection(array(
'driver' => 'pdo_mysql',
'user' => 'mattias',
'password' => 'fdfsdf',
'host' => 'fs1.rrtgy.se',
'dbname' => 'csmedia',
));
return $conn;
Is there a parameter I can set to do it using SSL?
The equivalent of something like this:
$link = mysql_connect("192.112.7.18","test","testpass",false,MYSQL_CLIENT_SSL)
You could try add to createConnection array 'driverOptions'
$conn = $connectionFactory->createConnection(array(
'driver' => 'pdo_mysql',
'user' => 'mattias',
'password' => 'fdfsdf',
'host' => 'fs1.rrtgy.se',
'dbname' => 'csmedia',
'driverOptions' => array(
PDO::MYSQL_ATTR_SSL_CA =>'/path/to/ssl-ca.pem'
),
));
More info about MYSQL SSL constants.
Notice, that some constants were added at php 5.3.7
However, SSL options are silently ignored in (at least) version 5.3.8: see the bug report.
I'm building a Website in Cakephp with variable databases.
I did this with the following code:
CONTROLLER:
$db_host = $DB_SET['Project']['db_host']; //From other database
$db_user = $DB_SET['Project']['db_user'];
$db_pass = $DB_SET['Project']['db_pass'];
$db_database = $DB_SET['Project']['db_database'];
ConnectionManager::create("client_db", array(
'datasource' => 'Database/Mysql',
'driver' => 'mysql',
'persistent' => false,
'host' => $db_host,
'login' => $db_user,
'password' => $db_pass,
'database' => $db_database,
'prefix' => '',
'encoding' => 'UTF8',
'port' => '',
));
$DB_LINE = $this->Page->findPage('3');
MODEL:
class Page extends Model {
public $useDbConfig = 'client_db';
function findPage($pagenr) {
$page = $this->find('first', array(
'conditions' => array (
'Page.id' => $pagenr)
));
return $page;
}
}
Now I also need to change of tables in the database on the Fly.
I do this using(Controller):
$tbl_current = array('tbl_cheques', 'tbl_wishes');
$this->Modelname->useTable = $tbl_current[$pageid]; //Getting the pageID from an url parameter.
Everything works fine, only if I don't wait a while before clicking another page I get this error:
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Page.fqlkdf' in 'field list'
This because Cake still have the previous table in his Cache.
If I wait a minute and then I change the page it works fine.
Any suggestions for this problem?
Thanks in advance,

Like you said, the table info is cached. So you just need to remove that cache:
Cache::clear(false, '_cake_model_');
Or, you can just temporarily disable cache
Configure::write('Cache.disable', false);
I was wondering is there a way i can set up the config where i can have two database entries that work when the environment is Local and when on Server.
I had come across a solution long time back on doing the switch through the code. Not able to find it now. How do you guys do it ?
I have a setup with local config files. I add the following lines at the bottom of app/config/core.php:
if(file_exists(ROOT.'/app/config/core.local.php')) {
include_once(ROOT.'/app/config/core.local.php');
}
In core.local.php I can override all the settings that differ on the local machine. The same goes for database.php.
I use a config class which does exactly that:
http://www.dereuromark.de/2010/08/17/development-vs-productive-setup
Recently I rewrote it for 2.0 as a plugin version.
It now takes care of test environments and cuts down the number of lines of configuration you will have to write:
http://www.dereuromark.de/2012/02/25/dynamic-database-switching/
I think it based on IP
at local environment IP is 127.0.0.1
and at live environment IP is never 127.0.0.1

Thanks
check with the lib/Cake/Utility/String.php see the function named
public static function uuid()
cheers
Thanks again
This worked
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'username',
'password' => 'password',
'database' => 'database_name',
'prefix' => '',
//'encoding' => 'utf8',
);
public $live = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'db.HOST.net',
'login' => 'username',
'password' => 'password',
'database' => 'database_name',
'prefix' => '',
//'encoding' => 'utf8',
);
public function __construct(){
if (isset($_SERVER) && isset($_SERVER['SERVER_NAME'])) {
if (strpos($_SERVER['SERVER_NAME'], 'localhost') === false) {
$this->default = $this->live;
}
}
}
}
I used this in my UserController
require_once 'Zend/Controller/Action.php';
AND
public function processAction()
{
$params = array('host' =>'localhost',
'username' =>'root',
'password' =>'',
'dbname' =>'zend'
);
$DB = new Zend_Db_Adapter_Pdo_Mysql($params);
$request = $this->getRequest();
$data = array('first_name' => $request->getParam('first_name'),
'last_name' => $request->getParam('last_name'),
'user_name' => $request->getParam('user_name'),
'password' => md5($request->getParam('password'))
);
$DB->insert('user', $data);
$this->view->assign('title','Registration Process');
$this->view->assign('description','Registration succes');
}
Which displayed following error. I do not have the php.ini access.
Fatal error: Class 'Zend_Db' not found in D:\xampp\xampp\htdocs\zend-test\zend-demo\application\controllers\UserController.php on line 42
i.e. on this line
$params = Zend_Db::factory('Pdo_Mysql', array(
'host' => 'localhost',
'username' => 'root',
'password' => '',
'dbname' => 'zend'
));
Thanks in advance!

Maybe this will help.
Tutorial on how to setup a working Zend framework
http://usingzendframework.blogspot.com/2007/01/setting-up-zend-framework.html
You need to include all of the Zend libraries you use - not just
equire_once 'Zend/Controller/Action.php';
Also, you need to do what Jurka specified - a much better and cleaner practice.
I would like to write a cake shell to do a nightly backup of my database using mysqldump. I could do this as a shell script, but if I can cram it into a CakePHP shell, then I will get the added benefit of it working across both the development and live server, if I can get it to automagically read my database config settings. I will cron the cake shell and have some peace-of-mind knowing that I have frequent backups of my DB.
In my shell I'm trying to build up a string which starts with "mysqldump --user=" and I'd like to get the username from app/config/database.php. How can I get at the data in database.php?
In cake 2.1 the format has changed to:
App::uses('ConnectionManager', 'Model');
$dataSource = ConnectionManager::getDataSource('default');
$username = $dataSource->config['login'];
The following snippet should do the trick:
App::import('Core', 'ConnectionManager');
$dataSource = ConnectionManager::getDataSource('default');
$username = $dataSource->config['login'];
In CakePHP 3.x the format has changed to -
use Cake\Datasource\ConnectionManager;
$source = ConnectionManager::get('default');
debug($source); #Debugging the result
Result :
object(Cake\Database\Connection) {
'config' => [
'password' => '*****',
'username' => '*****',
'host' => '*****',
'database' => '*****',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'encoding' => 'utf8',
'timezone' => 'UTC',
'cacheMetadata' => true,
'quoteIdentifiers' => false,
'log' => false,
'url' => null,
'name' => 'remote'
],
'driver' => object(Cake\Database\Driver\Mysql) {
'connected' => false
},
'transactionLevel' => (int) 0,
'transactionStarted' => false,
'useSavePoints' => false,
'logQueries' => false,
'logger' => null
}
Get the Result :
debug($source->config()); #Accessing the result
Result :
[
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'username' => 'username',
'password' => 'password',
'database' => 'database',
'encoding' => 'utf8',
'timezone' => 'UTC',
'cacheMetadata' => true,
'quoteIdentifiers' => false,
'log' => false,
'url' => null,
'name' => 'remote'
]
Just for sharing.
For any cakephp project, if using php as cronjob or command line to do large data processing I would build a standalone php script without cakephp, the reason for doing this because cakephp is slow (e.g. read & process 100K records).
To make my life simple I put all my standalone scripts under app/Vendor/myscripts/ (e.g: app/Vendor/myscripts/process.php)
below also the basic code to make sure you use the same database settings in standalone script with cakephp (tested with MySQL)
require_once '/XYZ/app/Config/database.php';
$database = new DATABASE_CONFIG;
try{
$dblink = new PDO('mysql:host='.$database->default['host'].';dbname='.$database->default['database'], $database->default['login'], $database->default['password'], array(PDO::ATTR_PERSISTENT => false));
$dblink->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$dblink->exec('SET CHARACTER SET '.$database->default['encoding']);
} catch (Exception $e) {
die('DB Error'. $e->getMessage());
}
Example in controller, Change multi DB for DataSources in CakePHP 2.5.x
App::uses('AppController', 'Controller');
class DemoController extends AppController {
public $uses = array('AppModel', 'GVA21', 'GVA01', 'GVA14', 'GVA24' );
public function test_dbs(){
$this->autoRender=false;
// Load ConnectManager
App::uses('ConnectionManager', 'Model');
// DataSource ['default']
$MDM = $this->GVA14->find('count');
echo "MDM.GVA14\n<br>";
debug($MDM);
// Get DataSource Config DB ['default'] and ['SRL']
$confDeafult = ConnectionManager::$config->default;
$confSrl = ConnectionManager::$config->SRL;
// Change DataSource ['SRL']
ConnectionManager::drop('default');
ConnectionManager::create('default',$confSrl); //<== Is permanet change Find All models Down
// $this->GVA01->setDataSource('SRL'); //<== Is temp change Find model
echo "SRL.GVA14\n<br>";

debug($SRL);
$SRL = $this->GVA21->find('count');
echo "SRL.GVA21\n<br>";
debug($SRL);
// Change to DataSource ['default']
debug(ConnectionManager::drop('default'));
ConnectionManager::create('default',$confDeafult); //<== Is permanet change Find All models Down
//$this->GVA01->setDataSource('default'); //<== Is temp change Find model
$MDM = $this->GVA01->find('count');
