Want to do server side validation in system.xml file in Magento config
I am new to Magento. I created a custom config page in the admin panel in the system config. I have given some fields using the system.xml file. Now I want to do server side validation for the phone number column, but I am struggling to do so.
I have provided the following code in the following path: Application / Code / Local / Envato / CustomConfig / etc. /config.xml
<?xml version="1.0"?>
<config>
<modules>
<Envato_CustomConfig>
<version>0.0.1</version>

My helper file: /app/code/local/Envato/CustomConfig/Helper/Data.php
<?php
class Envato_CustomConfig_Helper_Data extends Mage_Core_Helper_Abstract
{
}
My model file: app / code / local / Envato / CustomConfig / Model / Options.php
<?php
class Envato_CustomConfig_Model_Options
{
public function toOptionArray()
{
return array(
array('value'=>1, 'label'=>'One'),
array('value'=>2, 'label'=>'Two'),
array('value'=>3, 'label'=>'Three'),
array('value'=>4, 'label'=>'Four')
);
}
}
My model file: app / code / local / Envato / CustomConfig / Model / Options.php
<?php
class Envato_CustomConfig_Model_Number extends Mage_Core_Model_Abstract
{
public function save()
{
$number = $this->getValue(); //get the value from our config
$number = preg_replace('#[^0-9]#','',$number); //strip non numeric
if(strlen($number) < 10) //exit if we're less than 10 digits long
{
Mage::getSingleton('core/session')->addNotice('Phone Numbers need 10 digits.');
}
return parent::save();
}
}
My tag works in the system.xml file. But I am getting an error with datastore. I want to do server side validation before the data is stored in the db ... Can anyone help me do server side validation for these fields.
Thanks in Advance ......

I think there is a problem in your model class. Check out this detailed tutorial:
http://alanstorm.com/magento_system_config_validation
Updated:
class Envato_CustomConfig_Model_Number extends Mage_Core_Model_Config_Data{
public function save() {
$number = $this->getValue(); //get the value from our config
$number = preg_replace('#[^0-9]#','',$number); //strip non numeric
if(strlen($number) < 10) //exit if we're less than 10 digits long
{
Mage::getSingleton('core/session')->addError('Phone Numbers need 10 digits.');
return true;
}
return parent::save();
}
}
Use this model .. It will not save data until it is valid.
