  echo 'enctype="multipart/form-data"';
}
add_action('woocommerce_register_form_tag','AddEnctypeCustomRegistrationForms');

// Add file input html to register form
add_action('woocommerce_register_form','AddImageField');
function AddImageField() {   
  ?>    
    <p class="form-row validate-required" id="pro_image" data-priority="">
    <label for="pro_image" class="">Image (JPG, PNG, PDF)<abbr class="required" title="required">*</abbr></label>
    <span class="woocommerce-input-wrapper">
      <input type='file' name='pro_image' accept='image/*,.pdf' required>
    </span>
    </p> 
  <?php

// Validate new fields
function ValidateImageField( $errors, $username, $email ) {
  if ( isset( $_POST['pro_image'] ) && empty( $_POST['pro_image'] ) ) {
    $errors->add('pro_image_error', __( 'Please provide a valid image', 'woocommerce' ) );

// Save new field
function SaveImageField( $customer_id ) {
  if ( isset( $_FILES['pro_image'] ) ) {
    require_once( ABSPATH . 'wp-admin/includes/image.php' );
    require_once( ABSPATH . 'wp-admin/includes/file.php' );
    require_once( ABSPATH . 'wp-admin/includes/media.php' );
    $attach_id= media_handle_upload('pro_image', 0 );
    if ( is_wp_error( $attach_id) ) {
      update_user_meta( $customer_id,'pro_image', $_FILES['pro_image'] . ": " . $attach_id->get_error_message() );
    } else {
      update_user_meta( $customer_id,'pro_image', $attach_id);
    }
  }
}
add_action('user_register','SaveImageField',1);
