Product in search console

hello Pratik,

When I said ”That’s why, we have to use the information of the default variation to schema.org.”

I take an example with one product : https://lerepaireduchef.fr/crepiere-professionnelle/

In search console, my general URL is https://lerepaireduchef.fr/crepiere-professionnelle/ .
Except that as you can see, I only use variable products. A URL is created for each variation :
https://lerepaireduchef.fr/crepiere-professionnelle/?attribute_pa_chassis=rond&attribute_pa_crepe=35-cm&attribute_pa_epaisseur=fonte
https://lerepaireduchef.fr/crepiere-professionnelle/?attribute_pa_chassis=carre&attribute_pa_crepe=35-cm&attribute_pa_epaisseur=fonte
Etc.

In order to add a GTIN for each variation I use this plug in : WooCommerce UPC, EAN, and ISBN. The meta function seems to be hwp_var_gtin or hwp_product_gtin. You can check my back office in product page (données produit > Variations > Gtin)

There are two errors related to this:

1. The gtin does not appear in my structured data.

2. I cannot fill in the GTIN field in the inventory since it is already in the variations. WordPress tell me a duplicate GTIN error. That’s why I would like use GTIN of variation by default.

I can test with this two codes, can you tell me what modifications i need to make? :
/**
* Filter to add GTIN to Variable Products.
*
* @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(),’_wpm_gtin_code’, true);
$entity[‘gtin13’] = $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(),’_wpm_gtin_code’, true);
$entity[‘gtin13’] = $gtin_value;
return $entity;
}else{
return $entity;
}

});

add_filter( ‘rank_math/snippet/rich_snippet_product_entity’, function( $entity ) {
$entity[‘gtin13’] = ‘Gtin value’; // You can use here get_post_meta() function to add the value from cutom field in gtin attribute.
return $entity;
});

Thanks in advance

Hello Pratik,

I have tried several codes and none of them work, I must have been wrong.

You have access to my website, can you give me the correct code to add please?

Thank you

Hi pratik,

It’s seems to be : get_post_meta ($ variation [‘variation_id’], ‘hwp_var_gtin’, 1);

What is the right code please ?

add_filter( ‘rank_math/snippet/rich_snippet_product_entity’, function( $entity ) {
$entity[‘gtin13’] = ‘($ variation [‘variation_id’], ‘hwp_var_gtin’, 1);
return $entity;
});

I tested with this two codes and in the test of schema.org I have GTIN13 ”False” but the GTIN are true :

add_filter( ‘rank_math/snippet/rich_snippet_product_entity’, function( $entity ) {
$entity[‘gtin13’] = get_post_meta( $variation[‘variation_id’], ‘hwp_var_gtin’, 1 );
return $entity;
});

get_post_meta( $post_id, ‘hwp_product_gtin’, 1 );

add_filter( ‘rank_math/snippet/rich_snippet_product_entity’, function( $entity ) {
$entity[‘gtin13’] = get_post_meta( $post_id, ‘hwp_product_gtin’, 1 );
return $entity;
});

Hello Pratik,

we are going forward 🙂 It’s good for GTINs. Thank you so much !

My last mistake is related to the price.

I have correctly configured the price with VAT on woocommerce but in the structured data it is still the price excluding VAT that is displayed.

This is very important because it generates errors in google shopping.
I inquired and I was told about this function: woocommerce_structured_data_product_offer

Thank you for helping me !

Hello,

I have an error critic in this page, it’s come frome rankmath ? :https://lerepaireduchef.fr/garantie/

And in my function.php I added this code yesterday for GTIN :

// GTIN données structurées

add_filter( ‘rank_math/snippet/rich_snippet_product_entity’, function( $entity ) {
if ( ! is_product() ) {
return $entity;
}

$product = wc_get_product( get_the_ID() );
if ( ! $product->is_type( ‘variable’ ) ) {
$entity[‘gtin13’] = get_post_meta( get_the_ID(), ‘hwp_var_gtin’, true );
return $entity;
}
$variations = $product->get_available_variations();

if ( ! empty( $variations ) ) {
$entity[‘gtin13’] = get_post_meta( $variations[0][‘variation_id’], ‘hwp_var_gtin’, true );
}

return $entity;
} );
