Hi Support
i have form on front end as

array(
                'id' => 'your_phone',
                'type' => 'text',
                'required'   => true,
                'readonly'  => true,
                'name' => esc_html__( 'Your Phone' ),
                'std' => $profile->user_info->user_phone_number,
                'class' => 'col-md-6',
                'placeholder' => esc_html__( 'Your Phone' ),
