Woocommerce Product Meta – Strip dd and dt labels

No but you can use the filter woocommerce_order_items_meta_display to change the returned strings.

Like this?

add_filter('woocommerce_order_items_meta_display', 'wps_order_items_meta_display');
function wps_order_items_meta_display( $flat = false, $return = false, $hideprefix = '_', $delimiter = ", \n" ) {
    $output         = '';
    $formatted_meta = $this->get_formatted( $hideprefix );

    if ( ! empty( $formatted_meta ) ) {
      $meta_list = array();

      foreach ( $formatted_meta as $meta ) {
        if ( $flat ) {
          $meta_list[] = wp_kses_post( $meta['label'] . ': ' . $meta['value'] );
        } else {
          $meta_list[] = '
            <dt class="variationz-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( $meta['label'] ) . ':</dt>
            <dd class="variationz-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>
          ';
        }
      }

      if ( ! empty( $meta_list ) ) {
        if ( $flat ) {
          $output .= implode( $delimiter, $meta_list );
        } else {
          $output .= '<dl class="variationz">' . implode( '', $meta_list ) . '</dl>';
        }
      }
    }

    $output = apply_filters( 'woocommerce_order_items_meta_display', $output, $this );

    if ( $return ) {
      return $output;
    } else {
      echo $output;
    }
}

Not quite. woocommerce_order_items_meta_display gives you the HTML (with the DTs) and a reference to the class where this method is located.

With that you should be able to re-run most of the logic, but remove the DT/DD elements.

Ok, I’ve adapted to this but it still isn’t working.

function wps_order_items_meta_display($meta_list) {
          $meta_list[] = '
            <dt class="variation-test-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( $meta['label'] ) . ':</dt>
            <dd class="variation-test-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>
          ';

  return $meta_list;
}
add_filter('woocommerce_order_items_meta_display', 'wps_order_items_meta_display');

Do I need to deregister the original filter?

Please read the guide I posted to – there is no ‘original filter’ and your usage is wrong.

Look again at what it gives you:

$output = apply_filters( 'woocommerce_order_items_meta_display', $output, $this );

$output is a HTML string.

Ok, I’ve figured out the hook:

function filter_wps_order_items_meta_display( $output, $this ) {
      return $output;
    };
add_filter( 'woocommerce_order_items_meta_display', 'filter_wps_order_items_meta_display', 10, 2 );

which I can see works, but how do I strip the HTML tags off this?

$meta_list[] = '<dt class="variation-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( $meta['label'] ) . ':</dt>
						<dd class="variation-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>
					';

I’ve tried numerous ways of doing this trying to add a modified $meta_list array but it just seems to add it to the end of the default output rather than replacing it.

// define the woocommerce_order_items_meta_display callback
    function filter_wps_order_items_meta_display( $output, $instance ) { 

          $instance = '
            <dt class="variationz-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( $meta['label'] ) . ':</dt>
            <dd class="variationz-' . sanitize_html_class( sanitize_text_field( $meta['key'] ) ) . '">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>
          ';

          $output .= '<dl class="variation">' . implode( '', $instance ) . '</dl>';

      return $output;

    };
    // add the filter

So now you can either return strip_tags( $output ); or you can loop over the items in the same way the function which calls this function does, and just not include the tags in the first place.

Just can’t get this working. It either adds the new ones in addition to the existing or just doesn’t display at all.

// define the woocommerce_order_items_meta_display callback
function filter_wps_order_items_meta_display( $output, $this, $formatted_meta ) { 

  foreach ( $formatted_meta as $meta ) {
          $meta_list[] = '
            <dd class="variation">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>
          ';
      }

      $output .= '<dl class="variation">' . implode( '', $meta_list ) . '</dl>';

      return $output;

};
// add the filter
add_filter( 'woocommerce_order_items_meta_display', 'filter_wps_order_items_meta_display', 10, 2 );

Am I missing something here?

Change $output .= to $output = and you should be good.

Hi Mike,

It just outputs it empty:

<dl class="variation"></dl>
<dl class="variation"></dl>

So the filter works, it’s just not outputting the meta values. Here’s the filter:

// define the woocommerce_order_items_meta_display callback
function filter_wps_order_items_meta_display( $output, $this, $formatted_meta ) { 

  foreach ( $formatted_meta as $meta ) {
          $meta_list[] = '
            <dd class="variation">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>
          ';
      }

      $output = '<dl class="variation">' . implode( '', $meta_list ) . '</dl>';

      return $output;

};
// add the filter
add_filter( 'woocommerce_order_items_meta_display', 'filter_wps_order_items_meta_display', 10, 2 );

Wrong variable count:

add_filter( 'woocommerce_order_items_meta_display', 'filter_wps_order_items_meta_display', 10, 3 );

Hi,

Still just outputs empty:

<dl class="variation"></dl>
<dl class="variation"></dl>

Seems to be outputting the <dl> as foreach, rather than it being the container and inner <dd>’s, which should be the foreach loop, no?

Are you sure you’ve have not added more blocks of code? Because there is no foreach wrapping the DL output in the code you pasted above…

Nope, this is literally the entire thing:

// define the woocommerce_order_items_meta_display callback
function filter_wps_order_items_meta_display( $output, $this, $formatted_meta ) {
  $meta_list = array();
  foreach ( $formatted_meta as $meta ) {
          $meta_list[] = '<dd class="variation">' . wp_kses_post( wpautop( make_clickable( $meta['value'] ) ) ) . '</dd>';
      }

      $output = '<dl class="variation">' . implode( '', $meta_list ) . '</dl>';

      return $output;

};
// add the filter
add_filter( 'woocommerce_order_items_meta_display', 'filter_wps_order_items_meta_display', 10, 3 );
