remove lastname validation in checkout

1.要覆盖原生验证类，先定义在config文件里：

<models> 
 <customer_address>
                <rewrite>
                     <abstract>Bysoft_Mycustomer_Model_Address_Abstract</abstract>
                </rewrite>
 	</customer_address> 
</models>

 2.把文件/app/code/core/Mage/Customer/Model/Address/Abstract.php

复制到自己的模块之后类定义这样写：

class Bysoft_Mycustomer_Model_Address_Abstract extends Mage_Customer_Model_Address_Abstract
{

 3.注释掉验证lastname的地方

 /*
        if (!Zend_Validate::is($this->getLastname(), 'NotEmpty')) {
            $errors[] = Mage::helper('customer')->__('Please enter the last name.');
        }
 */

 4.注释掉checkout模板文件里填写lastname的字段

<!--  
    <div class="field name-lastname">
        <label for="<?php echo $this->getFieldId('lastname')?>" class="required"><em>*</em><?php echo $this->__('Last Name') ?></label>
        <div class="input-box">
            <input type="text" id="<?php echo $this->getFieldId('lastname')?>" name="<?php echo $this->getFieldName('lastname')?>" value="<?php echo $this->htmlEscape($this->getObject()->getLastname()) ?>" title="<?php echo $this->__('Last Name') ?>" class="input-text required-entry absolute-advice" <?php echo $this->getFieldParams() ?> />
        </div>
    </div>
-->

 

 5.覆盖后台订单列表的billing name 和shipping name 展示

 <blocks>
         <adminhtml>
              <rewrite>
                  <sales_order_grid>Bysoft_Mycustomer_Block_Adminhtml_Sales_Order_Grid</sales_order_grid>
              </rewrite>
         </adminhtml>
 </blocks>

 6.撰写覆盖类

class Bysoft_Mycustomer_Block_Adminhtml_Sales_Order_Grid extends Mage_Adminhtml_Block_Sales_Order_Grid
{


    protected function _prepareCollection()
    {
        $collection = Mage::getResourceModel($this->_getCollectionClass());       
        $collection ->getSelect()
        ->joinLeft(array('t2'=>'sales_flat_order_grid'),
        		't2.entity_id=main_table.entity_id',
        		array(
        				't2_shipping_name'=>"SUBSTRING(t2.shipping_name,1,LOCATE(' ', t2.shipping_name))",
        		)
        );
        
        
        

        $this->setCollection($collection);
        
        if ($this->getCollection()) {
        	$this->_preparePage();
        
        	$columnId = $this->getParam($this->getVarNameSort(), $this->_defaultSort);
        	$dir      = $this->getParam($this->getVarNameDir(), $this->_defaultDir);
        	$filter   = $this->getParam($this->getVarNameFilter(), null);
        
        	if (is_null($filter)) {
        		$filter = $this->_defaultFilter;
        	}
        
        	if (is_string($filter)) {
        		$data = $this->helper('adminhtml')->prepareFilterString($filter);
        		$this->_setFilterValues($data);
        	}
        	else if ($filter && is_array($filter)) {
        		$this->_setFilterValues($filter);
        	}
        	else if(0 !== sizeof($this->_defaultFilter)) {
        		$this->_setFilterValues($this->_defaultFilter);
        	}
        
        	if (isset($this->_columns[$columnId]) && $this->_columns[$columnId]->getIndex()) {
        		$dir = (strtolower($dir)=='desc') ? 'desc' : 'asc';
        		$this->_columns[$columnId]->setDir($dir);
        		$this->_setCollectionOrder($this->_columns[$columnId]);
        	}
        
        	if (!$this->_isExport) {
        		$this->getCollection()->load();
        		$this->_afterLoadCollection();
        	}
        }

        //return parent::_prepareCollection();
        return ;
    }

    protected function _prepareColumns()
    {

        $this->addColumn('real_order_id', array(
            'header'=> Mage::helper('sales')->__('Order #'),

        $this->addColumn('t2_shipping_name', array(

            'currency' => 'base_currency_code',
        ));

        $this->addColumn('grand_total', array(
            'header' => Mage::helper('sales')->__('G.T. (Purchased)'),
            'index' => 'grand_total',
            'type'  => 'currency',
            'currency' => 'order_currency_code',
        ));

        $this->addColumn('status', array(

            'width' => '70px',

        if (Mage::getSingleton('admin/session')->isAllowed('sales/order/actions/view')) {
            $this->addColumn('action',
                array(
                    'header'    => Mage::helper('sales')->__('Action'),

                    ),

        $this->addExportType('*/*/exportCsv', Mage::helper('sales')->__('CSV'));
        $this->addExportType('*/*/exportExcel', Mage::helper('sales')->__('Excel XML'));

        return $this;
    }

    
}

 值得注意的是两个方法均返回$this才能正确展示

数据库中并没有正正删除lastname字段。

此方法仅仅在展示的时候做了隐藏
