Hello,
Thank you for contacting Rank Math today.
Since your gtin value is saved as postmeta, you can use the following filter to dynamically load the value from the database:
/**
* Filter to Short-circuit Schema if a 3rd party is interested in generating their own data.
* Replace $schmea_type with schema name like article, review, etc.
* @param array $entity Snippet Data
* @return array
*/
add_filter( "rank_math/snippet/rich_snippet_{$schema_type}", function( $entity ) {
return $entity;
});
Looking forward to helping you. Thank you.
Thanks I added your code but there is still a missing GTIN or does it take some time to update itself?
Hello,
Thank you for contacting Rank Math today.
You need to add some custom code to this filter to get the saved value from the current product and pass it to the product schema. Here is an example that would work for single products:
/**
* Filter to add customize product schema.
*
* @param array $entity Snippet Data
* @return array
*/
add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
global $post;
$gtin_value = get_post_meta($post->ID,'_gtin', true);
if($gtin_value){
$entity['gtin8'] = $gtin_value;
return $entity;
}
return $entity;
});
Looking forward to helping you. Thank you.
Brilliant! Works Perfectly. Thankyou! Would it be possible to ask for code that passes the GTIN for variable products as well?
Hi there,
Thanks for the follow up.
Could you please try the following code:
/**
* Filter to add customize product schema.
*
* @param array $entity Snippet Data
* @return array
*/
add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
$product = new WC_Product( get_the_ID() );
if( $product->is_type( 'simple' ) ){
$gtin_value = get_post_meta($product->get_id(),'_gtin', true);
$entity['gtin8'] = $gtin_value;
return $entity;
}elseif($product->is_type( 'variable' )){
$variation = new WC_Product_Variation(get_the_ID());
$gtin_value = get_post_meta($variation->get_id(),'_gtin', true);
$entity['gtin8'] = $gtin_value;
return $entity;
}else{
return $entity;
}
});
Let me know how this goes.
Thank you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hi I am not sure the updated code is working? it adds the word “Array” to the SKU field and GTIN of the first product variant and adds the correct SKU but no GTIN to the second product variant?
I have added the product URL and login to this ticket. Many thanks for your help.
Hi there,
I cannot find the code that you are using to register and update the GTIN field. It looks like this code is the one that is updating the array value on the variable products as shown below:
The Code can be located from the left hand main wordpress Menu under Dynamik > Custom > Functions
/**
* Adding Custom GTIN Meta Field
* Save meta data to DB
*/
Thanks
