Use product attribute for brand in structured data

Hello,

Thanks for your query.

In the above code you shared, the value needs to be static. It does not accept a variable.

If you want to use pa_brand dynamically as your product brand, here’s the code you should use in your theme’s functions.php file:

/**
 * Filter to show brand value in snippet preview.
 */
add_filter( 'rank_math/vars/replacements', function( $vars ) {
    global $product;
 
    if ( ! $product ) {
        return $vars;
    }
 
    if ( isset( $vars['wc_brand'] ) ) {
        $brand = $product->get_attribute('pa_brand');
 
        // Use this code to get 1st element from brand attribute if multiple brands are assigned to a Product.
        $brands = explode( ',', $brand );
        if ( ! empty( $brands ) ) {
            $brand = $brands[0];
        }
       
        $vars['wc_brand']['example'] = $brand;
    }
 
  return $vars;
});
 
/**
 * Filter to replace wc_brand with custom value.
 */
add_filter( 'rank_math/replacements', function( $replacements ) {
    if ( is_singular( 'product' ) && isset( $replacements['%wc_brand%'] ) ) {
        $product = wc_get_product();
 
        $brand = $product->get_attribute('pa_brand');
        // Use this code to get 1st element from brand attribute if multiple brands are assigned to a Product.
        $brands = explode( ',', $brand );
        if ( ! empty( $brands ) ) {
            $brand = $brands[0];
        }
 
        $replacements['%wc_brand%'] = $brand; // Pass $brand to set meta value for brand.
    }
    return $replacements;
});

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.

Hi Paul,

Thanks for the question and apologies for the delay.

Todd’s version was making use of a different filter that is fired to replace the variables on the meta descriptions and titles.
You can try the following modified version of Todd’s code that assumes that you only have a single brand for each product:

/**
 * Filter to show brand value in snippet preview.
 */
add_filter( 'rank_math/vars/replacements', function( $vars ) {
    global $product;
 
    if(!$product){
        return $vars;
    }
 
    if(isset($vars['wc_brand'])){
        $brand = $product->get_attribute('brand');
       
        $vars['%wc_brand%']['example'] = $brand;
    }
 
  return $vars;
});

I hope this info helps. Thank you.
