I have two system config fields like password and password confirm field.i need to validate both are same. for this in my system.xml file i added <backend_model> note to both fields


in my model folder i created Test.php class as below

class Mycomany_Myextension_Model_Test extends Mage_Core_Model_Config_Data

public function _afterSave()
        $licence = $this->getValue(); //get the value from our config

        return parent::_afterSave();



My system config values

<input id="filemaker_general_fburl" name="groups[general][fields][fburl][value]" value="test" class=" input-text" type="text">

<input id="filemaker_general_fbheight" name="groups[general][fields][fbheight][value]" value="123" class=" input-text" type="text">

but it only return one value instead of two.i don't know what is the issue?


$licence = $this->getValue(); return only current field value

Try following way to pick other value

$anotherValue = $this->getData('groups/[name_of_group]/fields/[name_of_field]/value');

example: echo $anotherValue = $this->getData('groups/general/fields/fbwidth/value');

  • it 's returning blank page <input id="filemaker_general_fbwidth" name="groups[general][fields][fbwidth][value]" value="abc" class=" input-text" type="text"> this is inspected code echo $anotherValue = $this->getData('groups/[general]/fields/[fbwidth]/value'); – srinath madusanka Apr 7 '16 at 8:10

Try this:

   $storeId = 2; // ID of the store you want to fetch the value of
   $storeId = Mage::app()->getStore()->getStoreId();// Gets the current store's id

 echo $configValue = Mage::getStoreConfig('groups/general/fields/fbwidth/value', $storeId);
