Horizon Pulling Relative Image URLs

[thatdudelarry]

I worked with your support team a couple of months ago to fix this problem. I came up with a solution and implemented it on our sites, but figured it would be worth it to share here for potentially being used in future updates.

OLD - Beginning at line 501 - classes/class-sailthru-horizon.php

// image & thumbnail
if( has_post_thumbnail( $post_object->ID ) ) {
  $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' );
  $thumb = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'concierge-thumb' );
    $post_image = $image[0];
      $horizon_tags['sailthru.image.full'] = esc_attr($post_image);
    $post_thumbnail = $thumb[0];
      $horizon_tags['sailthru.image.thumb'] = $post_thumbnail;
}

NEW - Adds $url variable and utilizes make_absolute_url to ensure absolute urls are spidered

// image & thumbnail
if( has_post_thumbnail( $post_object->ID ) ) {
  $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'thumbnail' );
  $thumb = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'concierge-thumb' );
  $url = get_site_url();
  $post_image = $image[0];
    $horizon_tags['sailthru.image.full'] = WP_Http::make_absolute_url( esc_attr($post_image), $url );
  $post_thumbnail = $thumb[0];
    $horizon_tags['sailthru.image.thumb'] = WP_Http::make_absolute_url( $post_thumbnail, $url );
}
