Follow-up: “thumbnailUrl” to Schema Markup - Support

Resolved Artem Rev

Hello,

My other ticket was closed prematurely because the code that was given to me did not work.

In the original ticket located here: https://support.rankmath.com/ticket/adding-thumbnailurl-to-schema-markup/

I was trying to get the ‘thumbnailUrl’ to display the featured image of the post.

The code which was suggested was:
```
/**
* Collect data to output in JSON-LD.
*
* @param array $unsigned An array of data to output in json-ld.
* @param JsonLD $unsigned JsonLD instance.
*/
add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	if(is_single()){
           // If it is a post
           // Get its feature post URL:
           // grab the url for the full size featured image
           $featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full'); 

           // Now add that URL to the ThumbnailURL schema
	   $data['thumbnailURL'] = [
			$featured_img_url
		];
	    return $data;
	}
	return [];
}, 10, 2);
```
But this code gave an Unspecified Type error as shown in the screenshot link below. I think it was because this schema markup was not placed INSIDE the article schema but outside of it.

Is it possible to change this code so that it places the ‘thumbnailUrl’ inside the article schema?

Please advise.

Regards.

Hello,

Thank you for contacting Rank Math today.

To modify existing schema type, in your case article schema, you can would need to use the filter below:
```
/**
 * Filter to change the schema data.
 * Replace $schema_type with schema name like article, review, etc.
 * @param array $entity Snippet Data
 * @return array
 */
add_filter( "rank_math/snippet/rich_snippet_{$schema}_entity", function( $entity ) {
 return $entity;
});
```
Looking forward to helping you. Thank you.

Hello,

Thank you for the reply.

I’ve added the following code as per your suggestion with the modifications I THINK might work. Again, I am no coder, I have a very basic idea of how any of this works.

This is my code:
```
add_filter( "rank_math/snippet/rich_snippet_{$schema}_entity", function( $entity ) {
 $featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full'); 
	return $entity['thumbnailURL'] = '$featured_img_url';
	return $entity;
});
```
However, once emptying all caches and checking an article link in the structured data testing tool, the “thumbnailURL” does not appear in the Schema Markup.

Am I doing something wrong here with the code?

Please advise.

Hello,

You need to replace {$schema} in this line:
add_filter( "rank_math/snippet/rich_snippet_{$schema}_entity", function( $entity ) {

With the schema you want to modify. For example, the Article schema would be like this:
add_filter( "rank_math/snippet/rich_snippet_article_entity", function( $entity ) {

Looking forward to help you.

Hello Alberto,

I’ve made the changes as you suggested. Here is the code I used:
```
add_filter( "rank_math/snippet/rich_snippet_article_entity", function( $entity ) {
 $featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full'); 
	return $entity['thumbnailURL'] = '$featured_img_url';
});
```
When I ran the structured data testing tool, ALL of the rank math article schema was gone and was replaced just by “$featured_img_url”.

I do NOT want to replace everything, I just want to add to the existing schema a single line of ‘thumbnailURL’ = featured image URL.

How can I ADD to the existing data and not replace everything?

Hello Michael,

The code you gave was placing the “thumbnailURL” inside the article schema, but the URL was just “$featured_img_url” and not the actual URL. This is because there was extra (”) quotation marks around the parameter. After I removed them it worked.

For anyone else who might find this in the future. Here is the final code that worked.
```
/**
* Adds ThumbnailURL for Each Post into RankMath Schema Data
* Collect data to output in JSON-LD.
*
* @param array $unsigned An array of data to output in json-ld.
* @param JsonLD $unsigned JsonLD instance.
*/
add_filter( "rank_math/snippet/rich_snippet_article_entity", function( $entity ) {
 $featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full'); 
 $entity['thumbnailURL'] = $featured_img_url;
 return $entity;
});
```
