Introduction

Did you know that Magento 2, a leading eCommerce platform, offers the flexibility to create admin forms without relying on its UI component framework? This might come as a surprise, especially considering the common reliance on UI components for a streamlined, developer-friendly interface. This approach not only opens up a realm of customization possibilities but also caters to developers seeking a more hands-on method of form creation, adding a unique touch to their Magento 2 admin panel.

This blog post is aimed at unraveling the process of creating admin forms in Magento 2 without using UI components. You'll gain insights into the rationale behind opting for this approach, understand the step-by-step procedure, and explore the implications of such customization for your Magento 2 store. By the end, you'll be equipped with the knowledge to implement this customization, enhancing your admin panel's functionality and user experience.

Why Go Without UI Components?

The UI component system in Magento 2 is robust, offering a high level of abstraction and aiding in rapid development. However, there are scenarios where developers might need or prefer to bypass these components for admin form creation:

  • Performance Optimization: In some cases, UI components can introduce unwanted overhead, affecting page load times.
  • Greater Control and Customization: Directly handling the markup and scripts provides finer control over the form's behavior and appearance.
  • Learning and Flexibility: For developers keen on learning the internals of Magento 2 or those working on very custom or complex projects, this approach offers a deep dive and greater flexibility.

The Step-by-Step Guide

Creating an admin form without UI components involves several steps, from declaring your module to rendering the form in the admin panel. Here's how you can do it:

1. Module Declaration

First, ensure your custom module is properly declared in Magento 2. This involves creating a registration.php file and a module.xml file within your module's directory to register and declare your module within the Magento 2 framework.

2. Admin Route Definition

Your module needs an admin route, defined in the routes.xml file under your module's etc/adminhtml directory. This route will be the entry point for your admin form.

3. Controller Creation

Create a controller within your module that will serve the form. It should extend the \Magento\Backend\App\Action class, ensuring it has the right permissions and functionalities to be executed in the admin panel.

4. Form Creation

Now, the core part — creating the form. This involves PHP classes for the form and its elements. You'll directly use form and form element classes like \Magento\Framework\Data\Form and \Magento\Framework\Data\Form\Element\Text, offered by Magento 2, to construct your form programmatically.

5. Data Sources and Save Logic

Properly manage the form's data source and the save logic. This might involve creating a model and a resource model for your data, and handling the save action in your controller, ensuring data is validated and saved to the database accurately.

6. Rendering the Form

Finally, render the form in the admin UI by defining a layout XML file that specifies the block class responsible for rendering your form. Ensure your form is user-friendly and adheres to Magento's admin UI standards.

Implications and Best Practices

While crafting an admin form without UI components offers customization and control, it's essential to follow best practices for maintainability and compatibility:

  • Modular Development: Keep your customizations modular, ensuring they don't hinder the upgradability of Magento 2.
  • Adherence to Magento Standards: Even when bypassing UI components, adhere to Magento's coding standards, UI guidelines, and security best practices.
  • Comprehensive Testing: Rigorously test your custom form for security vulnerabilities, data integrity, and user experience across different admin roles.

Conclusion

Opting to create admin forms in Magento 2 without using UI components might seem daunting at first glance. However, with a clear understanding of Magento 2's architecture and a step-by-step approach, it's a feasible task that can offer significant benefits in terms of customization and performance. By following the guidelines and best practices outlined, developers can enhance their Magento 2 store's admin panel, offering a tailored experience that meets their unique business needs.
