Caching

Clear cache/reindex

<?php
// clear cache
Mage::app()->removeCache('catalog_rules_dirty');

// reindex prices
Mage::getModel('index/process')->load(2)->reindexEverything();
/*
1 = Product Attributes
2 = Product Attributes
3 = Catalog URL Rewrites
4 = Product Flat Data
5 = Category Flat Data
6 = Category Products
7 = Catalog Search Index
8 = Tag Aggregation Data
9 = Stock Status
*/

// Recreate a single index programmatically
Mage::getModel('index/process')->load(Mage_Catalog_Helper_Product_Flat::CATALOG_FLAT_PROCESS_CODE, 'indexer_code')->reindexEverything();
?>

Categories and Products

<?php
$_category = Mage::getModel('catalog/category')->load(89);
$_category_url = $_category->getUrl();
?>

Load product by id or sku

<?php
$_product_1 = Mage::getModel('catalog/product')->load(12);
$_product_2 = Mage::getModel('catalog/product')->loadByAttribute('sku','cordoba-classic-6-String-guitar');
?>

Get Configurable product's Child products

<?php
// input is $_product and result is iterating child products
$childProducts = Mage::getModel('catalog/product_type_configurable')->getUsedProducts(null, $product);
?>

Get Configurable product's Children's (simple product) custom attributes

<?php
// input is $_product and result is iterating child products
$conf = Mage::getModel('catalog/product_type_configurable')->setProduct($_product);
$col = $conf->getUsedProductCollection()->addAttributeToSelect('*')->addFilterByRequiredOptions();
foreach($col as $simple_product){
	var_dump($simple_product->getId());
}
?>

Is product purchasable?

<?php if($_product->isSaleable()) { // do stuff } ?>

Load Products by Category ID

<?php
$_category = Mage::getModel('catalog/category')->load(47);
$_productCollection = $_category->getProductCollection();
if($_productCollection->count()) {
	foreach( $_productCollection as $_product ):
		echo $_product->getProductUrl();
		echo $this->getPriceHtml($_product, true);
		echo $this->htmlEscape($_product->getName());
	endforeach;
}
?>

Get The Root Category

<?php
$rootCategoryId = Mage::app()->getStore()->getRootCategoryId();
$_category = Mage::getModel('catalog/category')->load($rootCategoryId);
// You can then get all of the top level categories using:
$_subcategories = $_category->getChildrenCategories();
?>

Return Product Attributes

<?php
$_product->getThisattribute();
$_product->getAttributeText('thisattribute');
$_product->getResource()->getAttribute('thisattribute')->getFrontend()->getValue($_product);
$_product->getData('thisattribute');
// The following returns the option IDs for an attribute that is a multiple-select field: 
$_product->getData('color'); // i.e. 456,499
// The following returns the attribute object, and instance of Mage_Catalog_Model_Resource_Eav_Attribute: 
$_product->getResource()->getAttribute('color'); // instance of Mage_Catalog_Model_Resource_Eav_Attribute
// The following returns an array of the text values for the attribute: 
$_product->getAttributeText('color') // Array([0]=>'red', [1]=>'green')
// The following returns the text for the attribute
if ($attr = $_product->getResource()->getAttribute('color')):
    echo $attr->getFrontend()->getValue($_product); // will display: red, green
endif;
?>

Get Simple Products of a Configurable Product

<?php
if($_product->getTypeId() == "configurable") {
    $ids = $_product->getTypeInstance()->getUsedProductIds();
?>
<ul>
    <?php
    foreach ($ids as $id) {
        $simpleproduct = Mage::getModel('catalog/product')->load($id);
    ?>
        <li>
        	<?php
        	echo $simpleproduct->getName() . " - " . (int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($simpleproduct)->getQty();
        	?>
        </li>				
    <?php
    }
    ?>
</ul>
<?php
}
?>

Getting Configurable Product from Simple Product ID in Magento 1.5+

<?php
$simpleProductId = 465;
$parentIds = Mage::getResourceSingleton('catalog/product_type_configurable')
    ->getParentIdsByChild($simpleProductId);
$product = Mage::getModel('catalog/product')->load($parentIds[0]);
echo $product->getId(); // ID = 462 (aka, Parent of 465)

# Generate URL to variant of configurable by $sku
$simple = Mage::getModel('catalog/product')->loadByAttribute('sku', $sku);
$productId = array_shift(Mage::getModel('catalog/product_type_configurable')->getParentIdsByChild($simple->getId()));
$url = Mage::getUrl('catalog/product/view', array( 'id' => $productId, 'option_id' => $simple->getVariant() ));

?>

Get the current category/product/cms page

<?php
$currentCategory = Mage::registry('current_category');
$currentProduct = Mage::registry('current_product');
$currentCmsPage = Mage::registry('cms_page');
?>

Get associated products

In /app/design/frontend/default/site/template/catalog/product/view/type/

<?php $_helper = $this->helper('catalog/output'); ?>
<?php $_associatedProducts = $this->getAllowProducts() ?>
<?php //var_dump($_associatedProducts); ?>
<br />
<br />
<?php if (count($_associatedProducts)): ?>
	<?php foreach ($_associatedProducts as $_item): ?> 
		<a href="<?php echo $_item->getProductUrl() ?>"><?php echo $_helper->productAttribute($_item, $_item->getName(), 'name') ?> | <?php echo $_item->getName() ?> | <?php echo $_item->getPrice() ?></a>
		<br />
		<br />
	<?php endforeach; ?>
<?php endif; ?>

Blocks

Call Static Block

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block-name')->toHtml(); ?>

Add JavaScript to page

First approach: page.xml - you can add something like

<action method="addJs"><script>path/to/my/file.js</script></action>

Second approach: Find page/html/head.phtml in your theme and add the code directly to page.html.

Third approach: If you look at the stock page.html mentioned above, you'll see this line

<?php echo $this->getChildHtml() ?>

Normally, the getChildHtml method is used to render a specific child block. However, if called with no paramater, getChildHtml will automatically render all the child blocks. That means you can add something like

<!-- existing line --> <block type="page/html_head" name="head" as="head">
<!-- new sub-block you're adding --> <block type="core/template" name="mytemplate" as="mytemplate" template="page/mytemplate.phtml"/>
...

to page.xml, and then add the mytemplate.phtml file. Any block added to the head block will be automatically rendered. (this automatic rendering doesn't apply for all layout blocks, only for blocks where getChildHtml is called without paramaters).

Customer handling

Check if customer is logged in

<?php $logged_in = Mage::getSingleton('customer/session')->isLoggedIn(); // (boolean) ?>

Logging and Exception handling

Log to custom file

<?php Mage::log('Your Log Message', Zend_Log::INFO, 'your_log_file.log'); ?>

Send success / errors to session

<?php Mage::getSingleton('core/session')->addSuccess($this->__('Hello world.')); ?>
<?php Mage::getSingleton('core/session')->addError($this->__('Bad world!!')); ?>

Configuration

Programmatically change or read Magento’s core config data

<?php
// find 'path' in table 'core_config_data' e.g. 'design/head/demonotice'
$my_change_config = new Mage_Core_Model_Config();
// turns notice on
$my_change_config->saveConfig('design/head/demonotice', "1", 'default', 0);
// turns notice off
$my_change_config->saveConfig('design/head/demonotice', "0", 'default', 0);


?>

Changing the Admin URL

Open up the /app/etc/local.xml file, locate the <frontName> tag, and change the ‘admin’ part it to something a lot more random, eg:

<frontName><![CDATA[supersecret-admin-name]]></frontName>

Clear your cache and sessions.

Magento: Mass Exclude/Unexclude Images

By default, Magento will check the 'Exclude' box for you on all imported images, making them not show up as a thumbnail under the main product image on the product view.

# Mass Unexclude
UPDATE`catalog_product_entity_media_gallery_value` SET `disabled` = '0' WHERE `disabled` = '1';
# Mass Exclude
UPDATE`catalog_product_entity_media_gallery_value` SET `disabled` = '1' WHERE `disabled` = '0';

Category Navigation Listings in Magento

Make sure the block that you’re working is of the type catalog/navigation. If you’re editing catalog/navigation/left.phtml then you should be okay.

<div id="leftnav">
	<?php $helper = $this->helper('catalog/category') ?>
	<?php $categories = $this->getStoreCategories() ?>
	<?php if (count($categories) > 0): ?>
		<ul id="leftnav-tree" class="level0">
			<?php foreach($categories as $category): ?>
				<li class="level0<?php if ($this->isCategoryActive($category)): ?> active<?php endif; ?>">
					<a href="<?php echo $helper->getCategoryUrl($category) ?>"><span><?php echo $this->escapeHtml($category->getName()) ?></span></a>
					<?php if ($this->isCategoryActive($category)): ?>
						<?php $subcategories = $category->getChildren() ?>
						<?php if (count($subcategories) > 0): ?>
							<ul id="leftnav-tree-<?php echo $category->getId() ?>" class="level1">
								<?php foreach($subcategories as $subcategory): ?>
									<li class="level1<?php if ($this->isCategoryActive($subcategory)): ?> active<?php endif; ?>">
										<a href="<?php echo $helper->getCategoryUrl($subcategory) ?>"><?php echo $this->escapeHtml(trim($subcategory->getName(), '- ')) ?></a>
									</li>
								<?php endforeach; ?>
							</ul>
							<script type="text/javascript">decorateList('leftnav-tree-<?php echo $category->getId() ?>', 'recursive')</script>
						<?php endif; ?>
					<?php endif; ?>
				</li>
			<?php endforeach; ?>
		</ul>
		<script type="text/javascript">decorateList('leftnav-tree', 'recursive')</script>
	<?php endif; ?>
</div>

Environment and Debugging

Helpful Debug watches

<?php
file_put_contents(sprintf('/tmp/layout_%s.xml', $this->getAction()->getFullActionName()), $this->getLayout()->getXmlString())
?>

Debug using zend

<?php echo Zend_Debug::dump($thing_to_debug, 'debug'); ?>

Run Magento Code Externally

<?php
require_once('app/Mage.php'); //Path to Magento
umask(0);
Mage::app();
// Run you code here
?>

Turn template hints on/off via database

UPDATE
`core_config_data`
SET
`value` = 0
WHERE
`path` = "dev/debug/template_hints"
OR
`path` = "dev/debug/template_hints_blocks";

Get methods of an object

First, use get_class to get the name of an object's class.

<?php $class_name = get_class($object); ?>

Then, pass that get_class_methods to get a list of all the callable methods on an object

<?php
$class_name = get_class($object);
$methods = get_class_methods($class_name);
foreach($methods as $method)
{
	var_dump($method);
}
?>

Check if module is installed/active

<?php
Mage::getConfig()->getModuleConfig('Sitewards_B2BProfessional')->is('active', 'true');
?>

Read and write configuration values

<?php
// Read data
$mailTemplateId = Mage::getStoreConfig('YOUR/PATH/HERE', $storeId);

// Write data
Mage::getModel('core/config')->saveConfig('YOUR/PATH/HERE', $value );
?>

Update all subscribers into a customer group (e.g. 5)

UPDATE
	customer_entity,
	newsletter_subscriber
SET
	customer_entity.`group_id` = 5
WHERE
	customer_entity.`entity_id` = newsletter_subscriber.`customer_id`
AND
	newsletter_subscriber.`subscriber_status` = 1;

<?php
$countryList = Mage::getResourceModel('directory/country_collection')
                    ->loadData()
                    ->toOptionArray(false);
