Magento category ID from product ID : Sometimes we need to get the category id from product id. Mage::registry(‘current_product’); is used to get the category of current product ie. selected product. Here in this tutorial we are going to explain the methods how you can get category id from product id.

Magento category ID from product ID

First load the product using the catalog product model then check if product is loaded and get category ids as below –

$productId = 100;
$product = Mage::getModel('catalog/product')->load($productId);
if ($product->getId()) {
        $categoryIds = $product->getCategoryIds();
        if (is_array($categoryIds) and count($categoryIds) >= 1) {
            $cat = Mage::getModel('catalog/category')->load($categoryIds[0]);
			echo $cat->getId()."
";
        }else{
        echo "No Category Found.";
       }
    }

The above example will give the category ids of the selected product as above.

Magento check if admin user logged in or not : While working with magento we sometimes need to decide whether user is logged from front end or admin. Mage::getSingleton(‘core/session’, array(‘name’ => ‘adminhtml’)); is used to get the admin end logged in user session. Here in this tutorial we are going to explain how you can check the customer login on magento backend ie admin.

Magento check if admin user logged in or not

You can check the customer is logged in simply as below –

Mage::getSingleton('core/session', array('name' => 'adminhtml'));

$userSession = Mage::getSingleton("customer/session");

if($userSession->isLoggedIn()) {
  echo "Is Logged In from Admin";
} else {
   echo "User Not Logged on Admin";
}

Using the above method you can check that the user is logged in from admin or not.

Magento check if customer is logged in : While working with magento we sometimes need to decide whether user is logged from front end or not. Mage::getSingleton(‘core/session’, array(‘name’ => ‘frontend’)); is used to get the front end logged in user session in Magento 1.x but In magento 2.x object manager $objectManager->get(‘Magento\Customer\Model\Session’) is used to get the customer session. Here in this tutorial we are going to explain how you can check the customer login on magento 1 and magento 2 front end.

Magento check if customer is logged in | Magento 2

It is very simple to check the looged in customer in magento 2, using the below method you can check whether the customer is logged in or not anywhere in the application. We have used object manager to get the customer session.

$customerSession = $objectManager->get('Magento\Customer\Model\Session');
if($customerSession->isLoggedIn()) {
   // customer logged in
}else{
// customer not logged in.
}

Magento 1.x

In magento 1 you can check the customer is logged in simply as below –

Mage::getSingleton('core/session', array('name' => 'frontend'));

  echo "Is Logged In";
} else {
   echo "User Not Logged";
}

Using the above method you can check that the user is logged in from front end or not.

Magento Get Payment Information : You can use order model Mage::getModel(‘sales/order’) to fetch the payment information. Using this model you can get the details about the payment method which was used while creating the order.

Magento Collection Filter : Magento collection is basically model type which contains the others models. Collections are used for loading data from data. You can join tables, add filter to them. You can perform joinInner(), joinLeft(), joinRight(), joinFull(), joinCross(),joinNatural() using collections.Varien_Data_Collection is used for collections in magento. Here in this tutorial we are going to explain how to use collection for various purpose efficiently. We will cover collection with syntax, example and uses.

Magento Collection Filter

Here are the details about the magento collection-

Magento get Collection

$collection = Mage::getModel('ModuleName/ModelName')->getCollection();

Where ModuleName – is name of module and ModelName is name of model you want to load.

Magento collection addfieldtofilter

Here a simple example to add the filter to the field –

$sku = 'testsku';
$collection = Mage::getModel('catalog/product')->getCollection()
                                               ->addFieldToFilter('sku', $sku);
$data = $collection->getData();
print_r($data);

When you will run the above example it will give you the product detail. The above example will produce the following query –

SELECT `e`.* FROM `catalog_product_entity` AS `e` WHERE (`e`.`sku` = ‘testsku’)

Magento collection addAttributeToFilter

Here a simple example to add the filter to the field –

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('status', 1); 
foreach($collection as $product){
 echo $product->getId()."
";
 echo $product->getSku()."
";
}

The example will give you all products where status is 1 ie. they are enabled.

Magento addAttributeToFilter Equal : eq (=)

The above example will give the results where status = 1;

Magento addAttributeToFilter Not Equal : neq (!=)

Here is an example to add the not equal condition in magento collection.

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('status', array('neq' => 1)); // With operator

Android Connect to Magento : While creating android application of magento we first need to understand how to connect with magento and how to pull the data from the magento using magento api. Here in this tutorial we are going to give the brief introduction how to connection with magento from andoid or ios using the soap or rest api.

Android Connect to Magento

ios

Magento provides the SOAP and REST api for application development. Here are main points which needs to start with android or ios app of magento.

1.SOAP API – http://www.magentocommerce.com/api/soap/introduction.html

2.REST API – http://www.magentocommerce.com/api/rest/introduction.html

3. Now create a New User in your Magento Store with roles. Login to magento Admin and go to system->WebServices->User&Roles.

4. Here create role and a user. Then assign the roles to this User.

Now you can call the soap method as in example below –

$client = new SoapClient('http://mydomain.com/soap/api/?wsdl');

$session = $client->login('apiUser', 'apiKey');
// get both from apiUser detail in magento.
$params = array(array(
    'status'=>array('eq'=>'pending')
));
$result = $client->call($session, 'sales_order.list', $params);

The above example will give you the sales order data.
