Creating new completely custom reports
First of all, you need to generate a custom module, create the following files:
/app/etc/modules/Mycompany_Mymodule.xml
/app/design/adminhtml/default/default/layout/mymodule.xml
/app/code/local/Mycompany/Mymodule/Block/adminhtml/Mymodule/Grid.php
/app/code/local/Mycompany/Mymodule/Block/adminhtml/Mymodule.php
/app/code/local/Mycompany/Mymodule/Block/Mymodule.php
/app/code/local/Mycompany/Mymodule/controllers/Adminhtml/MymoduleController.php
/app/code/local/Mycompany/Mymodule/etc/config.xml
/app/code/local/Mycompany/Mymodule/Helper/Data.php
/app/code/local/Mycompany/Mymodule/Model/Mymodule.php
Define your module on /app/etc/modules/Mycompany_Mymodule.xml:
<?xml version="1.0"?>
<config>
<modules>
<Mycompany_Mymodule>
<active>true</active>
<codePool>local</codePool>
</Mycompany_Mymodule>
</modules>
</config>
Complete the layout file which will update the admin view (I always do this first because I don't want to forget it). /app/design/adminhtml/default/default/layout/mymodule.xml
<?xml version="1.0"?>
<layout version="0.1.0">
<mymodule_adminhtml_mymodule_index>
<reference name="content">
<block type="mymodule/adminhtml_mymodule" name="mymodule" />
</reference>
</mymodule_adminhtml_mymodule_index>
</layout>
Create the config file with this content /app/code/local/Mycompany/Mymodule/etc/config.xml:
<?xml version="1.0"?>

Here we define the controller, the menu access and permissions, the model, the blocks and the helper.
Create the grid and specify all the columns /app/code/local/Mycompany/Mymodule/Block/adminhtml/Mymodule/Grid.php:
<?php
class Mycompany_Mymodule_Block_Adminhtml_Mymodule_Grid extends Mage_Adminhtml_Block_Report_Grid {
public function __construct() {
parent::__construct();
$this->setId('mymoduleGrid');
$this->setDefaultSort('created_at');
$this->setDefaultDir('ASC');
$this->setSaveParametersInSession(true);
$this->setSubReportSize(false);
}
protected function _prepareCollection() {
parent::_prepareCollection();
$this->getCollection()->initReport('mymodule/mymodule');
return $this;
}
protected function _prepareColumns() {
$this->addColumn('ordered_qty', array(
'header' =>Mage::helper('reports')->__('Quantity Ordered'),
'align' =>'right',
'index' =>'ordered_qty',
'total' =>'sum',
'type' =>'number'
));
$this->addColumn('item_id', array(
'header' => Mage::helper('mymodule')->__('Item ID'),
'align' => 'right',
'index' => 'item_id',
'type' => 'number',
'total' => 'sum',
));
$this->addExportType('*/*/exportCsv', Mage::helper('mymodule')->__('CSV'));
$this->addExportType('*/*/exportXml', Mage::helper('mymodule')->__('XML'));
return parent::_prepareColumns();
}
public function getRowUrl($row) {
return false;
}
public function getReport($from, $to) {
if ($from == '') {
$from = $this->getFilter('report_from');
}
if ($to == '') {
$to = $this->getFilter('report_to');
}
$totalObj = Mage::getModel('reports/totals');
$totals = $totalObj->countTotals($this, $from, $to);
$this->setTotals($totals);
$this->addGrandTotals($totals);
return $this->getCollection()->getReport($from, $to);
}
}
This file is clearest but I give you some tips about specific lines:
// this line indicates the model to use for get the data.
$this->getCollection()->initReport('mymodule/mymodule'); // it's used to indicate that this field must be totalized at the end.
'total' =>'sum', // this is executed when you click on the rows grid, in case you return false (like the example) nothing will happen when you click on the rows grid.
public function getRowUrl($row) {
For the next step, create the grid container block /app/code/local/Mycompany/Mymodule/Block/adminhtml/Mymodule.php:
<?php
class Mycompany_Mymodule_Block_Adminhtml_Mymodule extends Mage_Adminhtml_Block_Widget_Grid_Container {
public function __construct() {
$this->_controller = 'adminhtml_mymodule';
$this->_blockGroup = 'mymodule';
$this->_headerText = Mage::helper('mymodule')->__('Mymodule Report');
parent::__construct();
$this->_removeButton('add');
}
}
Here we add this line to remove the add button: // This must be always after the parent::__construct(); line. $this->_removeButton('add');
Create the block container /app/code/local/Mycompany/Mymodule/Block/Mymodule.php:
<?php
class Mycompany_Mymodule_Block_Mymodule extends Mage_Core_Block_Template {
public function _prepareLayout() {
return parent::_prepareLayout();
}
public function getMymodule() {
if (!$this->hasData('mymodule')) {
$this->setData('mymodule', Mage::registry('mymodule'));
}
return $this->getData('mymodule');
}
}
Create the controller /app/code/local/Mycompany/Mymodule/controllers/Adminhtml/MymoduleController.php:
<?php
class Mycompany_Mymodule_Adminhtml_MymoduleController extends Mage_Adminhtml_Controller_Action {
protected function _initAction() {
$this->loadLayout();
return $this;
}
public function indexAction() {
$this->_initAction()
->renderLayout();
}
public function exportCsvAction() {
$fileName = 'mymodule.csv';
$content = $this->getLayout()->createBlock('mymodule/adminhtml_mymodule_grid')
->getCsv();
$this->_sendUploadResponse($fileName, $content);
}
public function exportXmlAction() {
$fileName = 'mymodule.xml';
$content = $this->getLayout()->createBlock('mymodule/adminhtml_mymodule_grid')
->getXml();
$this->_sendUploadResponse($fileName, $content);
}
protected function _sendUploadResponse($fileName, $content, $contentType='application/octet-stream') {
$response = $this->getResponse();
$response->setHeader('HTTP/1.1 200 OK', '');
$response->setHeader('Pragma', 'public', true);
$response->setHeader('Cache-Control', 'must-revalidate, post-check=0, pre-check=0', true);
$response->setHeader('Content-Disposition', 'attachment; filename=' . $fileName);
$response->setHeader('Last-Modified', date('r'));
$response->setHeader('Accept-Ranges', 'bytes');
$response->setHeader('Content-Length', strlen($content));
$response->setHeader('Content-type', $contentType);
$response->setBody($content);
$response->sendResponse();
die;
}
}
Then the empty helper /app/code/local/Mycompany/Mymodule/Helper/Data.php:
<?php
class Mycompany_Mymodule_Helper_Data extends Mage_Core_Helper_Abstract
{
}
And for the last we create the model that will bring the data /app/code/local/Mycompany/Mymodule/Model/Mymodule.php:
<?php
class Mycompany_Mymodule_Model_Mymodule extends Mage_Reports_Model_Mysql4_Order_Collection
{
function __construct() {
parent::__construct();
$this->setResourceModel('sales/order_item');
$this->_init('sales/order_item','item_id');
}
public function setDateRange($from, $to) {
$this->_reset();
$this->getSelect()
->joinInner(array(
'i' => $this->getTable('sales/order_item')),
'i.order_id = main_table.entity_id'
)
->where('i.parent_item_id is null')
->where("i.created_at BETWEEN '".$from."' AND '".$to."'")
->where('main_table.state = \'complete\'')
->columns(array('ordered_qty' => 'count(distinct `main_table`.`entity_id`)'));
// uncomment next line to get the query log:
// Mage::log('SQL: '.$this->getSelect()->__toString());
return $this;
}
public function setStoreIds($storeIds)
{
return $this;
}
}
?>
This is a custom model that get the data from Magento core models, here you can define any model or if you already got your own DB/tables you can get the report data from it. // this line reset the original query that comes by default. $this->_reset();
I tried to add all these files but once I click on the new menu item of the report a blank page appears.
