Structured Data and Rich Snippets Problems

I have managed to get the Article (BlogPosting) Schema.Org workingg.

Paste this in a file called “json-ld.php” (You will probs need to create it.)

<?php
function get_post_data() {
  global $post;
  return $post;
}

function catch_that_image() {
  global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
  $first_img = $matches[1][0];

  if(empty($first_img)) {
    $first_img = "ENTER A DEFAULT IMAGE HERE";
  }
  return $first_img;
}

function word_count() {
    $content = get_post_field( 'post_content', $post->ID );
    $word_count = str_word_count( strip_tags( $content ) );
    return $word_count;
}

function comma_tags($tags, $show_links = true)
{
  if($tags)
  {
    $t = array();
    foreach($tags as $tag)
    {
      $t[] = (!$show_links) ? $tag->name : '<a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a>';
    }
    return implode(", ", $t);
  }
  else
  {
    return false;
  }
}

// stuff for any page
$payload["@context"] = "https://schema.org/";

// this has all the data of the post/page etc
$post_data = get_post_data();

// stuff for any page, if it exists
$category = get_the_category();

// stuff for specific pages
if (is_single() || is_singular()) {
  // this gets the data for the user who wrote that particular item
  $author_data = get_userdata($post_data->post_author);
  $post_url = get_permalink();
  $post_thumb = get_post_thumbnail_id($post->ID);

  $payload["@type"] = "BlogPosting";
  $payload["url"] = $post_url;
  $payload["author"] = array(
      "@type" => "Person",
      "name" => $author_data->display_name,
      );
  $payload["headline"] = $post_data->post_title;
  $payload["datePublished"] = get_the_date("Y-m-d");
  $payload["datePublished"] = get_the_date("Y-m-d");
  $payload["dateModified"] = get_the_modified_date("Y-m-d");
  $payload["wordCount"] = word_count();
  $payload["creator"] = array(
      "@type" => "Person",
      "name" => $author_data->display_name,
      );
  $payload["keywords"] = comma_tags(get_the_tags(), false);

  $img_url = catch_that_image();

	$imgdata = getimagesize($img_url);
	$width = $imgdata[0];
	$height = $imgdata[1];

  $payload["image"] = array(
	  "@type" => "ImageObject",
	  "url" => $img_url,
	  "height" => $height,
	  "width" => $width
  );

  $payload["mainEntityOfPage"] = array(
		"@type" => "WebPage",
		"@id" => $post_url
  );

  $payload["ArticleSection"] = $category[0]->cat_name;
  $payload["Publisher"] =
  			array(
	  			"@type" => "Organization",
	  			"name" => "ENTER ORGANIZATION NAME",
	  			"logo" => array(
		  			"@type" => "ImageObject",
		  			"url" => "ENTER ORGANIZATION LOGO"
		  		)
  			);
}

if (is_front_page()) {
  $payload["@type"] = "Organization";
  $payload["name"] = "Depression For Teens";
  $payload["logo"] = "ENTER ORGANIZATION LOGO HERE";
  $payload["url"] = "ENTER YOUR URL HERE";
  $payload["sameAs"] = array(
    "https://twitter.com/xxxxxxxxxxxxxxx",
    "https://www.facebook.com/xxxxxxxxxxxxxxx",
    "https://plus.google.com/xxxxxxxxxxxxxxx"
  );
  $payload["contactPoint"] = array(
    array(
      "@type" => "ContactPoint",
      "telephone" => "xxxxxxxxxxxxxxx",
      "email" => "xxxxxxxxxxxxxxx"
    )
  );
}

if (is_author()) {
  // this gets the data for the user who wrote that particular item
  $author_data = get_userdata($post_data->post_author);

  // some of you may not have all of these data points in your user profiles - delete as appropriate
  // fetch twitter from author meta and concatenate with full twitter URL
  $twitter_url =  " https://twitter.com/";
  $twitterHandle = get_the_author_meta('twitter');
  $twitterHandleURL = $twitter_url . $twitterHandle;

  $websiteHandle = get_the_author_meta('url');

  $facebookHandle = get_the_author_meta('facebook');

  $gplusHandle = get_the_author_meta('googleplus');
  $payload["@type"] = "Person";
  $payload["name"] = $author_data->display_name;
  $payload["email"] = $author_data->user_email;
  $payload["sameAs"] =  array(
    $twitterHandleURL, $websiteHandle, $facebookHandle, $gplusHandle

      );

}

You will need to handle the customisations EG (Oragnization details etc.) but that should work.

After you have made that file place the following before the </head> in the header.php file for your theme (preferably child theme)

<?php include('json-ld.php'); ?>
<script type="application/ld+json"><?php echo json_encode($payload); ?></script>

I am still having issues with the breadcrumb though.

I have fixed the breadcrumb issues by pasting this into my functions.php

add_filter( 'wpseo_breadcrumb_single_link', 'link_to_last_crumb' , 10, 2); 

function link_to_last_crumb( $output, $crumb){     

	$output = str_replace('<strong class="breadcrumb_last">'.$crumb['text'].'</strong>', '<span rel="v:child" typeof="v:Breadcrumb"><a href="'.$crumb['url'].'" rel="v:url" property="v:title">'.$crumb['text'].'</a></span>', $output);

    return $output;
}

I now get all breadcrumb items showing in Google’s rich snippet tester.
