Overview of checkout flow
- The video focuses on explaining the checkout flow in an e-commerce context, emphasizing its importance in the hybrid flow of online shopping.
- The typical flow starts from browsing products on the Product Detail (PD) or Product Listing Page (PLP), adding products to the cart, viewing the cart, and then proceeding to checkout.
- The checkout process consists of multiple steps:
- Address Selection/Entry – Users can select saved addresses from an address book or enter a new shipping address with country-specific address forms.
- Delivery Method – Users choose between delivery options like standard or premium (express) delivery, each with different charges.
- Payment Method – Users enter payment details. Currently, no third-party payment integration exists; mock data is used for validation.
- Final Review and Order Confirmation – Users confirm the order by checking a box and clicking a "Place Order" button.
Key Features and Validation
- The checkout flow enforces step validation: users cannot proceed to the next step without completing the current one correctly.
- Default selections are made (e.g., standard delivery if none chosen).
- Validation includes checking if the cart is empty, if address details are valid, and if payment info is correctly entered.
- If validation fails, users are redirected back to the incomplete step with an error message.
Technical Configuration and Architecture
- The checkout flow is configured in the back office under a "checkout flow group" (e.g., "responsive checkout group" for the B2C site).
- Configuration is defined in a file like
multiHyStHyCheckoutConfig.xml. - The checkout flow group acts as a container holding multiple checkout steps.
- Each checkout step has:
- A checkout step object with:
- Reference to the flow group
- Validator reference
- Transition URLs (next, previous, current)
- Progress bar ID (for breadcrumb navigation)
- A controller extending an abstract checkout step controller, implementing three mandatory methods:
enterStep()– entry logic for the stepnext()– logic for moving to the next stepback()– logic for moving to the previous step
- A GSP (JSP) page for rendering the UI of that step.
- A validator that ensures the step’s prerequisites are met before allowing progression.
- A checkout step object with:
Detailed Example: Delivery Address Step
- The delivery address controller:
- Retrieves the current cart and saved addresses.
- Dynamically adjusts the address form fields based on the selected country.
- Handles both GET (display form) and POST (submit form) requests.
- On successful validation and submission, calls the
next()method to proceed to the Delivery Method step.
- Validators check if the cart exists, if shipping items are present, and if the entered address data is valid.
- Transitions define URLs for navigation between steps and for redirection on validation failure.
Additional Notes
- There is an initial "multi" step that performs extra validations such as checking if the cart is empty before allowing access to the checkout steps.
- The progress bar or breadcrumb navigation is managed via configured request mappings in the checkout flow.
- The video discusses how to add new steps to the checkout flow by creating new checkout step objects, controllers, validators, and views, then adding them to the flow group configuration.
- The flow is designed to be extensible and modular.
Recommendations and Next Steps
- Viewers are advised to:
- Read the provided documentation on checkout steps and flow groups.
- Explore and understand the delivery address and multi-step checkout controllers.
- Study the validation logic and transitions between steps.
- Experiment with adding new steps or modifying existing ones.
- The instructor plans to provide documentation links and further guidance.
- There is a mention of upcoming review sessions and a suggested timeline for preparation.
Main Speakers / Sources
- The primary speaker appears to be a technical instructor or developer explaining the checkout flow implementation, configuration, and code structure.
- Participants include team members or trainees who ask questions or confirm understanding.
- No specific names are given, but the main presenter guides the session and shares screen/code walkthroughs.
