Drupal 9 Custom Login Page

Drupal 9 is a potent and adaptable content management system that enables users to effortlessly construct and administer websites. A prominent aspect of Drupal 9 is its capability to fashion unique login pages. This article will guide you through the steps of developing a customized login page in Drupal 9, while also offering my personal experiences and insights.

Why Custom Login Page?

Before diving into the technical details, let me share why having a custom login page is beneficial. By customizing the login page, you can create a seamless user experience that aligns with your website’s branding and design. It allows you to add your own logo, background, and other visual elements to make the login process more visually appealing and user-friendly.

Step 1: Theme Setup

The first step in creating a custom login page in Drupal 9 is to set up a custom theme. You can either create a new theme specifically for the login page or modify an existing theme. Personally, I recommend creating a separate theme to keep things organized.

To create a new theme, navigate to the “themes” directory in your Drupal installation and create a new folder with the name of your theme. Inside the theme folder, create a new file called “theme.info.yml” and add the necessary theme information.


name: My Custom Theme
type: theme
core_version_requirement: ^9 || ^8
base theme: stable

Don’t forget to replace “My Custom Theme” with the actual name of your theme.

Step 2: Implement the Login Page Template

Once you have set up your custom theme, it’s time to implement the login page template. In the theme folder, create another file called “templates/page–user–login.html.twig”. This file will be used to define the structure and layout of the login page.

In this template file, you can include HTML, CSS, and JavaScript code to create your desired login page design. You can add your logo, background image, form styling, and any other customizations that you want.


<!-- Your HTML code for the login page goes here -->

Feel free to get creative with the design and make it unique to your website’s brand.

Step 3: Assign the Template to the Login Page

Now that you have your custom login page template, it’s time to assign it to the login page. This can be done by implementing a preprocess function in your theme’s theme.theme file.

Open your theme’s theme.theme file and add the following code:


/**
* Implements hook_preprocess_HOOK() for page templates.
*/
function my_custom_theme_preprocess_page(&$variables) {
// Check if the current page is the user login page
if (\Drupal::routeMatch()->getRouteName() == 'user.login') {
// Assign your custom template to the login page
$variables['theme_hook_suggestions'][] = 'page__user__login';
}
}

This code checks if the current page is the user login page and assigns your custom template to it.

Conclusion
