Add PHTML file into another PHTML file in Magento

<?php echo $this->getLayout()->createBlock('catalog/product_view')->setTemplate('catalog/product/quickview.phtml')->toHtml(); ?>

Magento’s MVC Architecture

First of all, what is MVC?
MVC stands for Model-View-Controller. Any application that separates it’s data access, business logicand user interface is called MVC. There can be two types of MVC: convention-based and configuration-based. Example, cakePHP is convention-based, i.e. you just need to follow the instructions of the core system to get your module ready in just few lines. Magento is configuration-based, i.e. you need to specify each and every thing to your module’s config file in order to get it work. Magento has Controller (for Routing), Block (for Business Logic), Model (for DB access, sql) and Template file (for Presentation i.e. View).

How Magento’s MVC works:
1. When you enter the URL (something like, this URL is intercepted by one PHP file called index.php which instantiates Magento application
2. Magento application instantiates Front Controller object
3. Further, front controller instantiates Router objects (specified in module’s config.xml, global tag)
4. Now, Router is responsible to “match” the frontname which is in our URL
5. If “match” is found, it sees controller name and method name in the URL, which is finally called.
6. Now depending on what is written in action name (method name), it is executed. If any models are called in it, the controller method will instantiate that model and call the method in it which is requested.
7. Then the controller action (method) instantiate the Layout object, which calls Block specified for this action (method) name (Each controller action name have block and template file associated with it, which can be found at app/design/frontend or adminhtml/namespace/module/layout/module.xml file, name of layout file (module.xml) can be found in config.xml of that module, in layout updates tag).
8. Template file (.phtml) now calls the corresponding block for any method request. So, if you write $this->methodName in .phtml file, it will check “methodName” in the block file which is associated in module.xml file.
9. Block contains PHP logic. It references Models for any data from DB.
10. If either Block, Template file or Controller need to get/set some data from/to database, they can call Model directly like Mage::getModel(‘modulename/modelname’).

No square (white background) product images

<img src="<?php echo $this->helper('catalog/image')->init($this->getProduct(), 'thumbnail', $_image->getFile())->keepFrame(false)->resize(100); ?>" width="100"  ... />

Load Products by Category ID

$_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());

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

$class_name = get_class($object);
$methods = get_class_methods($class_name);
foreach($methods as $method)

Get Product Collection by Type

Here, I will be showing how you can get product collection from product type i.e. simple, configurable, bundle, grouped, and virtual.

$collectionSimple = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'simple'));

$collectionConfigurable = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'configurable'));

$collectionBundle = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'bundle'));

$collectionGrouped = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'grouped'));

$collectionVirtual = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'virtual'));

Send Email in Magento


$mail = Mage::getModel('core/email');
$mail->setToName('Your Name');
$mail->setToEmail('Youe Email');
$mail->setBody('Mail Text / Mail Content');
$mail->setSubject('Mail Subject');
$mail->setFromEmail('Sender Mail Id');
$mail->setFromName("Msg to Show on Subject");
$mail->setType('html');// YOu can use Html or text as Mail format
try {
Mage::getSingleton('core/session')->addSuccess('Your request has been sent');
catch (Exception $e) {
Mage::getSingleton('core/session')->addError('Unable to send.');
