Magento - Quote/order product item attribute based on user input
Introduction
Magento allows for custom attributes that are not displayed on product pages or attribute sets, but can be saved to quote/order items. This article will guide you through creating such an attribute, adding a frontend form element for user input, saving its value to quote/order items, and displaying it on order and invoice templates.
Steps to Create the Attribute:
-
Add Event Observer:
- Use catalog_product_load_after event to add the form element to the product page.
- Add the custom options to the additional_options option of the product model.
-
Save to Quote Item:
- Use sales_convert_quote_item_to_order_item event to copy the options from quote item to order item.
-
Display on Order Template:
- Modify the order view template (e.g., app/design/frontend/base/default/sales/order/view.phtml) to display the custom attribute.
Additional Features:
- Validation: Validate user input on the frontend using PHP code or a JS library.
- Template Control: Use a custom template to generate the HTML for the form element or control how the value is displayed on the frontend.
- Filtering Collections: Filter order collections using $collection->addFieldToFilter('additional_options.label', array('eq' => 'My Label'));.
Important Notes:
- Additional options are not product attributes or custom options.
- They are stored in the additional_options option field.
- Observer events are used to handle the process of adding, saving, and displaying the custom attribute.
- Translating the label and value of the custom attribute requires custom code or template modifications.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
