Be that as it may, some online saves may need to gather significant client data for additional focused on and particular communications with their clients. A few illustrations of portions that could be gathered incorporate occupation, jobtitle etc…

I will exhibit the expansion of another custom field to the information exchange shape asking new clients to enter their occupation and jobtitle.
Here I saw you logically ordered proce

Step 1: Create file app/etc/modules/Jwd_Customer.xml
Add this code

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Jwd_Customer>
        <codePool>local</codePool>
        <active>true</active>
        </Jwd_Customer>
    </modules>
</config>

Step 2: Create files and folder app/code/local/Jwd/Customer/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Jwd_Customer>
            <version>1.7.0.0</version>
        </Jwd_Customer>
    </modules>
    <global>
        <fieldsets>
            <customer_account>
                <occupation><create>1</create><update>1</update></occupation>
				<jobtitle><create>1</create><update>1</update></jobtitle>
            </customer_account>
        </fieldsets>
        <models>
            <Jwd_Customer>
                <class>Jwd_Customer_Model</class>
            </Jwd_Customer>
        </models>
        <helpers>
            <Jwd_Customer>
                <class>Jwd_Customer_Helper</class>
            </Jwd_Customer>
        </helpers>
        <resources>
            <customerattribute_setup>
                <setup>
                    <module>Jwd_Customer</module>
                    <class>Jwd_Customer_Model_Entity_Setup</class>
                </setup>
            </customerattribute_setup>
        </resources>
    </global>
</config>

Step 3: Create files and folder app/code/local/Jwd/Customer/Model/Entity/Setup.php

<?php
class Jwd_Customer_Model_Entity_Setup extends Mage_Customer_Model_Entity_Setup
{
    public function getDefaultEntities(){

        return array(

                'occupation'=>array(
                        'type'=> 'static',
                        'label'=> 'Occupation',
                        'visiable' => true,
                        'required' => true,
                        'sort_order' => 80,
                ),
				'jobtitle'=>array(
                        'type'=> 'static',
                        'label'=> 'Jobtitle',
                        'visiable' => true,
                        'required' => true,
                        'sort_order' => 80,
                )
        );
    }
}
?>

Step 4: Create files and folder app/code/local/Jwd/Customer/sql/customerattribute_setup/mysql4-install-0.1.0.php

<?php
$installer = $this;

$installer->startSetup();

$installer->addAttribute('customer', 'occupation', array(
	'label' => 'Occupation',
	'visible' => 1,
	'required' => 0,
	'position' => 1,
	'sort_order' => 80,
));
$installer->addAttribute('customer', 'jobtitle', array(
	'label' => 'Jobtitle',
	'visible' => 1,
	'required' => 0,
	'position' => 1,
	'sort_order' => 80,
));

$installer->endSetup();

$customer = Mage::getModel('customer/attribute')->loadByCode('customer', 'occupation');
$forms= array('customer_account_edit', 'customer_account_create', 'adminhtml_customer', 'checkout_register');
$customer->setData('used_in_forms', $forms);
$customer->save();

$customer = Mage::getModel('customer/attribute')->loadByCode('customer', 'jobtitle');
$forms= array('customer_account_edit', 'customer_account_create', 'adminhtml_customer', 'checkout_register');
$customer->setData('used_in_forms', $forms);
$customer->save();
?>
