Question

I have found several ways online but none seem to work. Does anyone know how to add the customer email to the grid for orders in Magento 1.4

Answer 1

copy
app/code/core/Mage/Adminhtml/Block/Sales/Order/Grid.php
to

app/code/local/Mage/Adminhtml/Block/Sales/Order/Grid.php

then under the following line

$collection = Mage::getResourceModel($this->_getCollectionClass());

add

$collection->getSelect()->joinLeft(array('sfo'=>'sales_flat_order'),'sfo.entity_id=main_table.entity_id',array('sfo.customer_email'));

then in the _prepareColumns() method add

    $this->addColumn('customer_email', array(
        'header' => Mage::helper('sales')->__('Customer Email'),
        'index' => 'customer_email',
        'filter_index' => 'sfo.customer_email',
    ));

note. you will need to add a ‘filter_index’ to all calls to addColumn pointing to main_table.field_name
