Magento 2 : Add Custom Message On Checkout Page On Shipping Address Change
Introduction
Magento 2 provides a robust and flexible platform for e-commerce businesses to manage their online stores. One of the key features of Magento 2 is its checkout process, which allows customers to easily and securely complete their purchases. However, sometimes, businesses may need to display custom messages to customers based on specific conditions, such as changes to their shipping address. In this article, we will discuss how to add a custom message on the checkout page when the shipping address changes in Magento 2.
Why Display Custom Messages on the Checkout Page?
Displaying custom messages on the checkout page can be beneficial for businesses in several ways:
- Improved customer experience: Custom messages can provide customers with relevant information about their order, such as shipping details or any issues with their address.
- Increased transparency: By displaying custom messages, businesses can keep customers informed about the status of their order, which can help build trust and loyalty.
- Enhanced security: Custom messages can be used to notify customers of any security issues or concerns related to their order.
Adding Custom Message on Checkout Page on Shipping Address Change
To add a custom message on the checkout page when the shipping address changes, you will need to create a custom module in Magento 2. Here's a step-by-step guide to help you achieve this:
Step 1: Create a Custom Module
First, you need to create a custom module in Magento 2. You can do this by running the following command in your terminal:
php bin/magento module:create --module-name="CustomMessage"
This will create a new directory called CustomMessage in the app/code directory of your Magento 2 installation.
Step 2: Create a Model
Next, you need to create a model that will handle the logic for displaying the custom message. Create a new file called Model.php in the CustomMessage/Model directory:
// app/code/CustomMessage/Model/Model.php
namespace CustomMessage\Model;
use Magento\Framework\Model\AbstractModel;
class Model extends AbstractModel
{
protected $_eventPrefix = 'custom_message';
public function __construct(
\Magento\Framework\Model\Context $context,
\Magento\Framework\Registry $registry,
\Magento\Framework\Model\ResourceModel\AbstractResource $resource = null,
\Magento\Framework\Data\Collection\AbstractDb $resourceCollection = null,
array $data = []
) {
parent::__construct($context, $registry, $resource, $resourceCollection, $data);
}
public function getCustomMessage()
{
// Get the shipping address
$shippingAddress = $this->_objectManager->get(\Magento\Checkout\Model\ShippingAddress::class);
// Get the selected shipping method
$shippingMethod = $shippingAddress->getShippingMethod();
// Check if the shipping method is 'columbia'
if ($shippingMethod == 'columbia') {
// Return the custom message
return 'Custom message for Columbia shipping method';
} else {
// Return an empty string if the shipping method is not 'columbia'
return '';
}
}
}
Step 3: Create a Block
Next, you need to create a block that will display the custom message on the checkout page. Create a new file called Block.php in the CustomMessage/Block directory:
// app/code/CustomMessage/Block/Block.php
namespace CustomMessage\Block;
use Magento\Framework\View\Element\Template;
use Magento\Framework\View\Element\Template\Context;
use Magento\Checkout\Model\ShippingAddress;
class Block extends Template
{
protected $_objectManager;
public function __construct(
Context $context,
\Magento\Framework\ObjectManager\ObjFactory $objectManager,
array $data = []
) {
parent::__construct($context, $data);
$this->_objectManager = $objectManager;
}
public function getCustomMessage()
{
// Get the shipping address
$shippingAddress = $this->_objectManager->get(ShippingAddress::class);
// Get the selected shipping method
$shippingMethod = $shippingAddress->getShippingMethod();
// Check if the shipping method is 'columbia'
if ($shippingMethod == 'columbia') {
// Return the custom message
return 'Custom message for Columbia shipping method';
} else {
// Return an empty string if the shipping method is not 'columbia'
return '';
}
}
}
Step 4: Create a Layout File
Next, you need to create a layout file that will display the custom message on the checkout page. Create a new file called checkout_index_index.xml in the CustomMessage/etc/frontend/layout directory:
<!-- app/code/CustomMessage/etc/frontend/layout/checkout_index_index.xml -->
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="shipping-methods">
<block class="CustomMessage\Block\Block" name="custom_message" template="CustomMessage::block.phtml"/>
</referenceContainer>
</body>
</page>
Step 5: Create a Template File
Finally, you need to create a template file that will display the custom message on the checkout page. Create a new file called block.phtml in the CustomMessage/view/frontend/templates directory:
<!-- app/code/CustomMessage/view/frontend/templates/block.phtml -->
<?php
/**
- @var \CustomMessage\Block\Block $block
*/
?>
<div class="custom-message">
<?php echo $block->getCustomMessage(); ?>
</div>
Step 6: Register the Custom Module
Finally, you need to register the custom module in the etc/module.xml file:
<!-- app/code/CustomMessage/etc/module.xml -->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="CustomMessage" setup_version="1.0.0"/>
</config>
Step 7: Run the Setup Script
To run the setup script, navigate to the Magento 2 root directory and run the following command:
php binagento setup:upgrade
Step 8: Run the Di Compile
To run the di compile, navigate to the Magento 2 root directory and run the following command:
php bin/magento di:compile
Step 9: Run the Deployment
To run the deployment, navigate to the Magento 2 root directory and run the following command:
php bin/magento setup:static-content:deploy
Step 10: Clear the Cache
To clear the cache, navigate to the Magento 2 root directory and run the following command:
php bin/magento cache:clean
Step 11: Clear the Cache Again
To clear the cache again, navigate to the Magento 2 root directory and run the following command:
php bin/magento cache:flush
That's it! You have now successfully added a custom message on the checkout page when the shipping address changes in Magento 2.
