placeholders like %wc_size% & %product_cat%

Hello,

I updated the code on your site, the Product category, brand, size now appears on the frontend.

Can you please confirm?

Thank you.

Hello,

Yes, you can use implode function to show product categories separated by the comma. I’ve done that for you.

Here is a reference code:

add_action( 'rank_math/vars/register_extra_replacements', function() {
	RankMath\Helper::register_var_replacement(
			'product_category',
			'get_product_category',
			array(
				'name'    => esc_html__( 'Product category.', 'rank-math' ),
				'desc'    => esc_html__( 'Product category of the current product', 'rank-math' ),
				'example' => get_product_category(),
			)
		);

	RankMath\Helper::register_var_replacement(
			'wc_size',
			'get_product_size',
			array(
				'name'    => esc_html__( 'Product size.', 'rank-math' ),
				'desc'    => esc_html__( 'Product size of the current product', 'rank-math' ),
				'example' => get_product_size(),
			)
		);
});

function get_product_category() {
	$product_id = rank_math_get_product();
	
	if ( ! $product_id ) {
		return null;
	}

	$product_cats = wp_get_post_terms( $product_id, 'product_cat', array( 'fields' => 'names' ) );
	if ( empty( $product_cats ) ) {
		return null;
	}

	return implode( ', ',$product_cats );
}

function get_product_size() {
	$product_id = rank_math_get_product();
	
	if ( ! $product_id ) {
		return null;
	}

	$product = wc_get_product( $product_id );
	if ( ! $product ) {
		return;
	}
	$size = $product->get_attribute('pa_size');
	// Use this code to get 1st element from brand attribute if multiple brands are assigned to a Product.
	$sizes = explode( ',', $size );
	if ( ! empty( $sizes ) ) {
		$size = $sizes[0];
	}

	return $size;
}

function rank_math_get_product() {
	$product_id = isset( $_GET['post'] ) ? $_GET['post'] : get_queried_object_id();
	if ( ! $product_id && ( ! is_singular( 'product' ) || ! function_exists( 'wc_get_product' ) ) ) {
		return null;
	}

	return $product_id;
}

Hope that helps. Thank you.
