In this case, this will create 2 entries in the core_config_data table : trans_email/ident_relance/email and trans_email/ident_relance/name.

To retrieve values, use this :

Mage::getStoreConfig('trans_email/ident_relance/email');
Mage::getStoreConfig('trans_email/ident_relance/name');

save or update a new entry :

$data = new Mage_Core_Model_Config();
$data->saveConfig('adin/ssid', 'value', 'default', 0);

and retrieve saved value :

$value = Mage::getConfig()->getNode('default/adin/ssid');

You may need to specify scope and scope code to retrieve the value

$value = Mage::getConfig()->getNode('default/sogen/file_number', 'default', 0 );

Update or create a value inside the installer (data, no sql)

  $installer->setConfigData('customer/address/prefix_show', 0);

In a setup file

 $installer->setConfigData('your/path', 'value', 'stores', 1);
 $installer->deleteConfigData('your/path', 'stores');

The post Magento using core_config_data table appeared first on Agence de Développement Informatique du Nord.

After installing a new instance, you change in the database, table core_config_data, these 2 entry : web/unsecure/base_url and web/secure/base_url. Don’t forget to change this one too : web/cookie/cookie_domain and web/cookie/cookie_path
