Sort the username and email fields

Hi,

You can follow Johannes's reply to customize the registration form https://support.metabox.io/topic/registration-username-as-email-duplicated-fields-avatar-visibility-issue/page/2/#post-21465.

function add_more_registration_fields( $fields ) {
        $fields = [
            'first_name'  => [
                'name'     => 'First Name',
                'id'       => 'first_name',
                'type'     => 'text',
                'required' => 1
            ],
            'last_name'  => [
                'name'     => 'Last Name',
                'id'       => 'last_name',
                'type'     => 'text',
                'required' => 1
            ],
            'username'  => [
                'name'     => __( 'Username', 'mb-user-profile' ),
                'id'       => 'user_login',
                'type'     => 'text',
                'required' => true,
            ],
            'email'     => [
                'name'     => __( 'Email', 'mb-user-profile' ),
                'id'       => 'user_email',
                'type'     => 'email',
                'required' => true,
            ],
            'password'  => [
                'name'     => __( 'Password', 'mb-user-profile' ),
                'id'       => 'user_pass',
                'type'     => 'password',
                'required' => true,
                'desc'     => '<span id="password-strength" class="rwmb-password-strength"></span>',
            ],
            'password2' => [
                'name'     => __( 'Confirm Password', 'mb-user-profile' ),
                'id'       => 'user_pass2',
                'type'     => 'password',
                'required' => true,
            ],
            // ... add more fields here
        ];
        return $fields;
    }
add_filter( 'rwmb_profile_register_fields',  'add_more_registration_fields' );

Get more form filters here https://docs.metabox.io/extensions/mb-user-profile/#form-fields-filters. They are located in the file wp-content/plugins/mb-user-profile/src/DefaultFields.php.

Hi,

Please check the file functions.php in the activated theme. Or you can use the plugin Code Snippets to run the code https://wordpress.org/plugins/code-snippets/.

Hi,

Did you require/include the file "custom-functions/functiones.php" in the main file functions.php of the "astra-child" theme?

You can add the code to the file functions.php, screenshot https://share.getcloudapp.com/5zuA6xGb
or just use the plugin Code Snippets to see it works.

Hi,

Sorry if I misunderstood your questions. I will try to reply sequently.

1. If you use the filter to modify the register form, you can only use the fields in the code as default fields and add more fields by adding the attribute id="meta-box-id" to the shortcode to create different forms.
2. Please try again with this code (remove the array key)

function add_more_registration_fields( $fields ) {
        $fields = [
            [
                'name'     => __( 'Email', 'mb-user-profile' ),
                'id'       => 'user_email',
                'type'     => 'email',
                'required' => true,
            ],
            [
                'name'     => __( 'Password123', 'mb-user-profile' ),
                'id'       => 'user_pass',
                'type'     => 'password',
                'required' => true,
                'desc'     => '<span id="password-strength" class="rwmb-password-strength"></span>',
            ],
            [
                'name'     => __( 'Confirm Password123', 'mb-user-profile' ),
                'id'       => 'user_pass2',
                'type'     => 'password',
                'required' => true,
            ],
            // ... add more fields here
        ];
        return $fields;
}

3. No, because we use the filter to modify the field settings while the custom table needs the meta box settings. Read more on the documentation https://docs.metabox.io/extensions/mb-custom-table/#using-custom-tables.
4. I will inform the Keymaster to take a look at that case.
