I tried everything, but nothing seems to work. This is my code:
Block/Adminhtml/Customer/Group/Edit/Form.php
<?php
class Devra_Membership_Block_Adminhtml_Customer_Group_Edit_Form extends Mage_Adminhtml_Block_Customer_Group_Edit_Form
{
protected function _prepareLayout()
{
parent::_prepareLayout();
$form = $this->getForm();
$fs = $form->getElement('base_fieldset');
$fs->addField('customer_group_plan_price', 'text',
array(
'name' => 'plan_price',
'label' => 'Precio del plan',
'title' => 'Precio del plan',
'class' => '',
'required' => false
)
);
$customerGroup = Mage::registry('current_group');
if( Mage::getSingleton('adminhtml/session')->getCustomerGroupData() ) {
$form->addValues(Mage::getSingleton('adminhtml/session')->getCustomerGroupData());
Mage::getSingleton('adminhtml/session')->setCustomerGroupData(null);
} else {
$form->addValues($customerGroup->getData());
}
}
}

sql/devra_membership_setup/install-1.0.0.php
<?php
$installer = $this;
$installer->startSetup();
$conn->addColumn($installer->getTable('customer/customer_group'), 'customer_group_plan_price', array(
'type' => Varien_Db_Ddl_Table::TYPE_INTEGER,
'unsigned' => true,
'nullable' => false,
'default' => '0',
'comment' => 'Price of the plan',
));
$installer->endSetup();
I tried to add a controller with a save action, but it doesn't work too.
