Your website registration form is one of the first points where you collect data from users. Customizing it with additional fields lets you capture specific information at signup, such as company name, skill level, or preferences, and use that data to personalize each user’s experience.
The Login & Signup block in Nexter Blocks for the WordPress Block editor lets you add ACF custom fields directly to your registration form. Each field maps to an ACF field group configured for user roles, and the data is saved to the WordPress user profile when someone registers.

Best Used For:
- Membership and community sites that need to collect profile details (company name, bio, job title) at signup
- Online course platforms that require student background or skill level at registration
- WooCommerce stores that need additional customer information during account creation
Requirement – This block is a part of Nexter Blocks, make sure it is installed & activated to enjoy all its powers. This feature requires the Advanced Custom Fields (ACF) or Secure Custom Fields (SCF) plugin. Make sure it is installed and activated.
Note: Make sure new user registration is enabled in the Settings > General page.
First, in the ACF plugin, create a field group with the custom fields you want to add to the registration form.
In the Rules under Location Rules, make sure it is set based on User Role. You can set the rule to All users, or match the New User Default Role configured in Settings > General. Setting this correctly matters because ACF only displays a field group to users matching the location rule. If the location rule does not match the role assigned to new registrants, the fields will not appear on the registration form.

Once you have set your custom fields in ACF, add the Login & Signup block to the page. Go to Forms > Type and select Register or Login & Register from the dropdown. Use Register when the page is dedicated to new account creation only. Use Login & Register when you want both the login and registration forms on the same page.
Select the appropriate layout from the Layout section.

Once your form fields are ready, go to the Register tab and click the +Add Field button.
From the Field dropdown, select ACF. This tells the block to pull a field definition from your ACF field group rather than using a default WordPress form field.
In the Key field, enter the Name value of the ACF field you want to add to the form. This is the field’s internal identifier in ACF, not its display label. You can find it inside the field settings in your ACF field group. If the Key does not match the ACF field name exactly, the field will not appear on the registration form.
From the ACF Field dropdown, select the field type that matches how you configured the field in ACF, for example Text, Email, Select, or Checkbox. This controls how the field renders on the registration form in the WordPress Block editor.
From the Width section, control how much horizontal space the field takes up on the form. Set it to 50% when you want two fields side by side on desktop, or 100% for a full-width field. This is useful when you have multiple custom fields and want to control the layout of your registration form.
The field is visible on the front end only.
Once a user registers on your site, the custom field data is added to the WordPress user profile section. You can view and manage this data at any time from Users > [Username] > Edit. If your custom fields collect personal information such as phone numbers or addresses, see How to Make WordPress User Registration GDPR Compliant to ensure you meet data privacy requirements.
Once your registration form is set up, give returning users a way to log in from any page on your site. See How to Add a Login Button in WordPress Header Menu to add a visible login trigger to your site header.
