Dev Guide: Shopware 6.5/6.6 Class & Namespace Updates

Shopware 6.5 and 6.6 introduced several significant changes to classes, namespaces, data attributes, and security mechanisms that developers need to be aware of when updating or maintaining their Shopware projects. This article provides a concise yet comprehensive overview of these changes, along with observations on their impact and how to adapt your code accordingly.

Introduction

As Shopware evolves, updates often bring improvements, optimizations, and new features. However, they may also introduce changes that can affect existing codebases. Understanding these changes is crucial for ensuring a smooth transition and leveraging the new capabilities effectively.

This article focuses on the following key areas:

• Elasticsearch namespace migration
• Media path handling updates
• Method changes in AvailableCombinationLoader
• Symfony framework upgrade to version 6
• Stock handling updates
• Storefront Bootstrap upgrade
• Offcanvas Cart data attribute changes
• CSRF protection changes
• Rule Builder enhancements

Let's delve into each of these changes in detail.

1. Elasticsearch Namespace Migration

Change Overview

• Previous Namespace: ONGR\ElasticsearchDSL
• New Namespace: OpenSearchDSL

Impact

All classes and methods that interact with Elasticsearch need to update their namespaces to reflect the migration from ONGR\ElasticsearchDSL to OpenSearchDSL.

Action Required

Update import statements and references in your code to use the new namespace.

Example

// Before
use ONGR\ElasticsearchDSL\Query\MatchQuery;

$query = new MatchQuery('field', 'value');

// After
use OpenSearchDSL\Query\MatchQuery;

$query = new MatchQuery('field', 'value');

Observations

This change aligns with the broader industry shift towards OpenSearch, a community-driven fork of Elasticsearch. Updating to the new namespace ensures compatibility with ongoing developments and support.

2. Media Path Handling

Change Overview

Media paths are now stored directly in the database instead of being generated dynamically.

Impact

Classes and services that previously relied on dynamic path generation need to access media paths from the database.

Action Required

Adjust your code to use the getPath() method from the MediaEntity.

Example

// Before (dynamic path generation)
$mediaPath = $mediaService->getPath($mediaId);

// After (database-stored path)
$mediaPath = $mediaEntity->getPath();

Observations

Storing media paths in the database improves performance by reducing computation overhead. It also provides more consistency and reliability in media handling.

3. Method Update in AvailableCombinationLoader

Change Overview

The load() method in AbstractAvailableCombinationLoader has been replaced with loadCombinations().

Impact

Any custom classes that extend AbstractAvailableCombinationLoader must implement the new loadCombinations() method instead of the old load() method.

Action Required

Rename or refactor your method implementations to align with the new method name and signature.

Example

// Before
$combinations = $combinationLoader->load($productId);

// After
$combinations = $combinationLoader->loadCombinations($productId);

Observations

This change enhances clarity by providing a more descriptive method name. It may also involve additional parameters or return types, so reviewing the method signature is essential.

4. Symfony Framework Upgrade to Version 6

Change Overview

Shopware has upgraded its Symfony components to version 6.

Impact

The upgrade introduces some breaking changes due to deprecated features and changes in method signatures. Custom code relying on older Symfony features may break or produce warnings.

Action Required

Review your code for any deprecated Symfony features and update them to be compatible with Symfony 6.

Observations

Staying up-to-date with the latest Symfony version ensures better performance, security, and access to new features. However, it requires careful code review and testing to ensure compatibility.

5. Stock Handling Updates

Change Overview

A new Stock API has been introduced, available behind the STOCK_HANDLING feature flag.

Impact

Classes and services related to stock management may need to adapt to the new API structure, especially if they interact directly with stock data.

Action Required

Use the new stock handling methods provided by the API and ensure that any stock-related logic aligns with the updated structure.

Example

// Before
$stock = $productEntity->getStock();

// After
$stock = $stockService->getStock($productId);

Observations

The new Stock API provides a more robust and flexible way to manage stock, potentially simplifying customizations and integrations with external systems.

6. Storefront Bootstrap Upgrade

Change Overview

The Storefront has been upgraded from Bootstrap 4 to Bootstrap 5, and jQuery has been removed as a dependency.

Impact

Custom JavaScript code and templates that rely on jQuery or Bootstrap 4 components need to be refactored to align with Bootstrap 5 and use native JavaScript where necessary.

Action Required

• Replace jQuery usage with native JavaScript or Bootstrap 5 utilities.
• Update Bootstrap classes and components to match Bootstrap 5 naming and structure.

Observations

Bootstrap 5 brings improvements in performance, reduced dependencies, and modernized components. While updating can be time-consuming, it offers long-term benefits in terms of maintainability and user experience.

7. Offcanvas Cart Data Attribute Changes (Shopware 6.6)

Change Overview

In Shopware 6.6, there has been a subtle but significant change in the data attribute used to trigger the offcanvas cart functionality.

• Previous Data Attribute: data-offcanvas-cart
• New Data Attribute: data-off-canvas-cart

Impact

Custom templates or themes that use the data-offcanvas-cart attribute without hyphens may find that the offcanvas cart no longer functions as expected because the JavaScript listener in Shopware 6.6 looks for the hyphenated version.

Action Required

Update the data-offcanvas-cart attribute in your templates to data-off-canvas-cart.

Example

<!-- Before -->
<div class="header-cart" data-offcanvas-cart="true">
    <!-- Cart content -->
</div>

<!-- After -->
<div class="header-cart" data-off-canvas-cart="true">
    <!-- Cart content -->
</div>

Observations

This change is not well-documented in the official Shopware 6.6 release notes but is crucial for the proper functioning of the offcanvas cart. The JavaScript responsible for initializing the cart functionality relies on the data-off-canvas-cart attribute, and any deviation can prevent the cart from working.

Additional Notes

• Consistency is Key: Ensure all instances where the offcanvas cart attribute is used are updated.
• Test Thoroughly: After making the change, test the cart functionality to confirm it works as expected.
• Check for Similar Changes: Other data attributes or event listeners may have undergone similar updates; review your custom templates accordingly.

8. CSRF Protection Changes

Change Overview

Shopware 6.5 and later versions have removed the explicit CSRF token handling in templates, transitioning to a SameSite cookie strategy for CSRF protection.

Impact

Templates and forms that previously included CSRF tokens using the sw_csrf function will encounter errors because this function no longer exists.

Action Required

• Remove CSRF Token Functions: Eliminate the usage of {{ sw_csrf('route_name') }} from your templates.
• Rely on SameSite Cookies: Trust the built-in SameSite cookie strategy for CSRF protection, which doesn't require explicit tokens in forms.
• Adjust Form Attributes: Ensure that forms and AJAX requests are configured correctly to work with the new CSRF protection mechanism.

Example

<!-- Before -->
<form action="{{ path('frontend.checkout.line-item.add') }}" method="post">
    {{ sw_csrf('frontend.checkout.line-item.add') }}
    <!-- Form fields -->
    <button type="submit">Add to Cart</button>
</form>

<!-- After -->
<form action="{{ path('frontend.checkout.line-item.add') }}" method="post">
    <!-- Form fields -->
    <button type="submit">Add to Cart</button>
</form>

Observations

• Error Resolution: Removing the sw_csrf function resolves the "Unknown 'sw_csrf' function" error.
• Security Maintenance: The SameSite cookie strategy continues to protect against CSRF attacks without additional tokens.
• Simplified Templates: Forms become cleaner and slightly simpler without the need for CSRF tokens.

Additional Notes

• Testing is Crucial: After making these changes, thoroughly test form submissions to ensure they work correctly.
• Understand the New Mechanism: Familiarize yourself with how the SameSite cookie strategy operates to maintain a secure application.
• Update Documentation: Ensure any internal documentation reflects this change to prevent future confusion.

9. Handling Issues with the Offcanvas Cart

Scenario Overview

After updating templates and removing the sw_csrf function, developers may still encounter issues where clicking the "Add to Cart" button opens the offcanvas cart, but it appears empty.

Root Cause

The offcanvas cart may not display the added items due to missing or incorrect parameters in the form submission, specifically the absence of the redirectTo input field.

Action Required

• Add the redirectTo Parameter: Include a hidden input field named redirectTo with the value frontend.cart.offcanvas in your add-to-cart forms.
• Ensure Correct Data Attributes: Verify that all necessary data attributes are present and correctly named.

Example

<form action="{{ path('frontend.checkout.line-item.add') }}" method="post">
    <input type="hidden" name="redirectTo" value="frontend.cart.offcanvas"/>
    <input type="hidden" name="lineItems[{{ product.id }}][id]" value="{{ product.id }}">
    <!-- Other form fields -->
    <button type="submit">Add to Cart</button>
</form>

Observations

• Functionality Restoration: Adding the redirectTo parameter informs Shopware to load the offcanvas cart upon adding an item, ensuring the cart displays correctly.
• Attention to Detail: Small omissions like missing input fields can lead to significant functionality issues, highlighting the importance of thorough code review.

Additional Notes

• Consistency in Data Attributes: Double-check that data attributes like data-product-id are correctly set.
• Review JavaScript Dependencies: Ensure that any JavaScript plugins or components related to the cart are properly loaded and initialized.
• Clear Cache: After making changes, clear the Shopware cache and your browser cache to prevent outdated files from causing issues.

10. Rule Builder Enhancements

Change Overview

The Rule Builder API has been expanded to support more complex conditional logic.

Impact

Custom rules and conditions may need adjustments to align with the new interfaces or methods provided by the enhanced Rule Builder.

Action Required

Review the Rule Builder documentation and update custom rule implementations to ensure compatibility.

Observations

Enhanced rule capabilities allow for more precise targeting and customization within Shopware. Leveraging these new features can lead to better adaptability and personalized experiences for end-users.
