GTIN in Schema

Hello,

Thank you for contacting Rank Math today.

You can make use of the following filter to pass the EAN field value to the Rank Math schema:

/**
 * Filter to add Brand Name for Products.
 *
 * @param array $entity Snippet Data
 * @return array
 */
add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
    $entity['gtin8'] = ''; //pass the value here
    return $entity;
});

Looking forward to helping you. Thank you.

Hello,

Chitra, could you open a new thread so we can help you there (so you can add any extra info in the Sensitive Data field)?

Jack, about your question, meanwhile we don’t usually provide custom code and also I don’t know how you are storing that field in the database (using custom post meta? using acf fields?), I have modified the previous code and it should work for you (or just need a few tweaks if not):

/**
 * Filter to add Brand Name for Products.
 *
 * @param array $entity Snippet Data
 * @return array
 */
add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
    $entity['gtin8'] = get_post_meta(get_the_ID(), 'ean', TRUE);
    return $entity;
});

Hope it helps.
