Here in this tutorial we are going to explain how you can get the last inserted in table using the magento model.

Magento get last insert id

If you are using magento model you can get last inserted id simply as below. Suppose we are adding data using the model Mage::getModel(‘user/profile’). For this model here is an example –

     
     $model = Mage::getModel('user/profile');
     $model->setFirstname($firstName); 
     $model->setLastname ($lastName); 
     $model->save();

$customer->loadByEmail($email);
if($customer->getId()){     
     $customer->setFirstname($firstName); 
     $customer->setLastname ($lastName);

Magento Add / Update customer address programmatically

Mage::getModel(‘customer/address’) is used to update the customer address. Here is an example in which we are going to update the customer address.

$customerId = 101;
$shippingData = array(
    'firstname' => $firstName,
    'middlename' => $middleName,
    'lastname' => $lastName,
    'prefix' => $prefix,
    'suffix' => $suffix,
    'company' => $company,
    'street' => $street,
    'country_id' => $country,
    'city' => $city,
    'region_id' => '',
    'region' => $region,
    'postcode' => $postal,
    'country_id' => $country, 
    'telephone' => $telephone,
    'fax' => $fax,
);

$customerAddress = Mage::getModel('customer/address');

if ($customer->getDefaultShipping()){
    $defaultShippingId = $customer->getDefaultShipping()
    $customerAddress->load($defaultShippingId); 
} else {   
    $customerAddress
        ->setCustomerId($customerId)
        ->setIsDefaultBilling('0')
        ->setIsDefaultShipping('1')
        ->setSaveInAddressBook('1');
}

try {
    $customerAddress->setData($shippingData);
    $customerAddress->save();
} catch (Exception $e) {
    Mage::log('Error .' . $e->getMessage());
}

The above example will update the customer address. ->setIsDefaultBilling() is used to save the default billing address. If you set ->setIsDefaultBilling(1) it will save customer address as default billing address. ->setIsDefaultShipping() is used to set the default shipping address if you set ->setIsDefaultBilling(1) it will save the default shipping address as customer address. If you want to save this address in address book then set ->setSaveInAddressBook(‘1’) else set ->setSaveInAddressBook(‘0’).

Magento update product programmatically :Working with magento we sometimes need to update the products programmatically instead of updating the product from magento admin. Mage::getModel(‘catalog/product’) is used to load the product object and then set the new value which you want to update. In this tutorial we are going to cover various scenarios with example.

Magento update product programmatically

Suppose we have product id and Let us update product name, description & sku as below-

public function updateProduct(){
try{
$productId = 100;
$product = Mage::getModel("catalog/product")->load($productId); 
$product->setStatus(1);      
$product->setName('Test Product');
$product->setSku('test-sku');
$product->setDescription("This is test product description.");
$product->setShortDescription("This is short description of product.");
$product->save();
}catch (Exception $e) {
 Mage::logException($e->getMessage());            
}
}

The above example loads the product id with 100 and updates the product name, sku, description and short description.

magento update product attribute programmatically

Here is another example to update the product’s attribute.

public function updateProduct(){
try{
$productId = 100;
$product = Mage::getModel("catalog/product")->load($productId); 
$attrCode = 'my_attr';
$attrVal = "someVal";
$product->setData($attrCode, $attrVal)
         ->getResource()
         ->saveAttribute($product, $attributeCode);
}catch (Exception $e) {
 Mage::logException($e->getMessage());            
}
}

The above example will update the attribute my_attr with new value $attrVal. Thus you can update any attribute of product.

Magento update product Quantity programmatically

public function updateProduct(){
try{
$productId = 100;
$product = Mage::getModel("catalog/product")->load($productId); 
$product->setQty(99);  
$product->save();
}catch (Exception $e) {
 Mage::logException($e->getMessage());            
}
}

The above example loads the product and updates the quantity.

Magento Delete Products Programmatically : Some times we need to delete the products in magento. You can delete products programmatically from magento catalog. Before deleting products make sure you have set the store id because you can have multiple stores. In this example we are going to cover how to delete products programmatically in magento.

Magento Delete Products Programmatically

Here are the methods to delete products in magento –

Delete Single Product –

load( $productId )->delete(); 
 
 }catch(Exception $e){
 echo $e->getMessage();
 } 
 ?>

The above method loads products & Deletes the product.

Magento Delete all Products Programmatically –

If you want to delete all the products. Create a new file at root and add the below lines of code which will delete all products one by one from magento.
1. Create a file at root – deleteProducts.php
2. Add the below code in this file.
3. Run this file as : www.yourdomain.com/deleteProducts.php

 setCurrentStore( Mage_Core_Model_App :: ADMIN_STORE_ID );
	$storeId = 1;
    $products = Mage :: getResourceModel('catalog/product_collection')->setStoreId($storeId)->getAllIds();
    if(is_array($products))
    {
        foreach ($products as $key => $productId)
        {
            try
            {
                $product = Mage::getModel('catalog/product')->load($productId)->delete();
                
            } 
            catch (Exception $e) 
            {
                Mage::log("Unable to delete product with ID: ". $productId .");
            }
        }
    }
  
 ?>

set_time_limit(0); & ini_set(‘memory_limit’,’512M’); is set to fix timeout and memory limit problems. The above example will delete all products from magento so be sure before running the above script.

Magento send transactional email programmatically: In Magento, we know emails are automatically sent on certain actions such as order creation, invoice generation etc. Each email has a template which is used in that email. You can find the template in admin under the tag – System->Transaction Email where you can manage them. We sometimes need to send transactional email in another module programmatically. Here in this tutorial, we are going to explain how you can send transactional emails.

Magento send transactional email programmatically

Here in this example we assume that you have created an email template. So in this example we will use template id ie. 10 . Here is an example –

 $senderName,'email' => $senderEmail);
//recepient
$email = "customer@example.com";
$name = "Kelly";

// Set variables that can be used in email template
$variables = array('custom_var' => $yourCustomVariable);

$translate = Mage::getSingleton('core/translate');
$storeId = Mage::app()->getStore()->getId();
// Now Send Transactional Email
try{
Mage::getModel('core/email_template')->sendTransactional($templateId, $sender, $email, $name, $variables , $storeId);
}
catch(Exception $e){
 echo $e->getMessage();
}
?>

$variables = array(‘custom_var’ => $yourCustomVariable); You use this to pass the custom variables to your email template if you want in template. Using the above example you can send the transactional email easily.
