How to Create a Dynamic Product Attribute in Magento Based on User Input During Quote/Order Creation?

Magento - Product attribute based on user input during Quote/Order creation

Introduction

This article will provide solutions to create a custom product attribute that is not stored on products or displayed on the product edit page. Instead, it will be saved to order/quote items and displayed on orders, invoices, and other related documents. Additionally, it will be configurable by the customer on the frontend before adding a product to the cart.

Problem Definition

  • Add a custom product attribute that is not part of the standard product attributes or custom options.
  • The attribute should be visible and configurable by customers on the product page before adding it to the cart.
  • The attribute's value should be saved with the quote/order item.
  • The attribute's value should be displayed on orders, invoices, sales emails, and other relevant documents.
  • Provide the ability to filter order collections based on the attribute's value.

Solution

Capturing, Validating, and Saving the Attribute Value

  1. Event Observer: Use an event observer, such as catalog_product_load_after, to capture and store the attribute's value.
  2. Customer Input: Add a form element to the product page to allow customers to input the attribute's value.
  3. Validation: Validate the customer input on the server-side to ensure it meets the specified criteria.
  4. Additional Options: Store the validated value in the additional_options key of the product model's custom_options array.

Displaying the Attribute Value

  1. Order and Invoice Display: Customize the order and invoice templates to display the attribute's value alongside other product details.
  2. Email Display: Update the sales emails templates to include the attribute's value in the relevant sections.

Filtering Order Collection

  1. Custom Attribute: Create a custom attribute in the database to store the attribute's value.
  2. Event Observer: Use an event observer, such as sales_convert_quote_item_to_order_item, to populate the custom attribute.
  3. Order Collection: Query the order collection using the custom attribute's value as the filter criteria.

Reordering Support

To ensure the attribute's value persists during reorders, use a checkout event observer, such as checkout_cart_product_add_after, to copy the attribute value to the quote item.

Translation

  • Use event observers to translate the attribute's label and value in quote and order items.
  • Override the default display templates to handle translation if necessary.

How to combine two php arrays unique values? How to combine two php arrays unique values? Jul 02, 2025 pm 05:18 PM

To merge two PHP arrays and keep unique values, there are two main methods. 1. For index arrays or only deduplication, use array_merge and array_unique combinations: first merge array_merge($array1,$array2) and then use array_unique() to deduplicate them to finally get a new array containing all unique values; 2. For associative arrays and want to retain key-value pairs in the first array, use the operator: $result=$array1 $array2, which will ensure that the keys in the first array will not be overwritten by the second array. These two methods are applicable to different scenarios, depending on whether the key name is retained or only the focus is on

php regex for password strength php regex for password strength Jul 03, 2025 am 10:33 AM

To determine the strength of the password, it is necessary to combine regular and logical processing. The basic requirements include: 1. The length is no less than 8 digits; 2. At least containing lowercase letters, uppercase letters, and numbers; 3. Special character restrictions can be added; in terms of advanced aspects, continuous duplication of characters and incremental/decreasing sequences need to be avoided, which requires PHP function detection; at the same time, blacklists should be introduced to filter common weak passwords such as password and 123456; finally it is recommended to combine the zxcvbn library to improve the evaluation accuracy.
