Make %excerpt% pull from Product Description Instead of Short Description

Hello @wooq123

Thank you for contacting the support.

Assuming you are on the latest version of the plugin, in WooCommerce products, the short description is stored in the excerpt field.

By default, we are adding excerpts to the SEO Description. You can use the below filter to change that behavior:

Hope that helps.

Will this only affect the auto generated excerpt for products that don’t have a custom excerpt? Also, when I apply this I don’t see any change on preview excerpt when editing a product.

Adding that filter to my child theme’s functions.php file has not changed the behavior, and I’m still seeing my product short descriptions in the preview section when I edit products. Are there any plans to simply add a setting into the plugin that changes the source of the default excerpt? I imagine I’m not the only one who doesn’t one excerpts generated from a short description.

Hello @wooq123

Please use the following code in your themes’s functions.php file to show excerpt from the main content:

add_action( 'rank_math/frontend/description', function( $description ) {

	if ( ! is_singular() ) {
		return $description;
	}

	 global $post;
	 $desc = RankMath\Post::get_meta( 'description', $post->ID );

	 if ( $desc ) {
	 	return $desc;
	 }

	if ( empty( $post ) || empty( $post->post_content ) ) {
		return $description;
	}

	$keywords     = RankMath\Post::get_meta( 'focus_keyword', $post->ID );
	$post_content = RankMath\Paper\Paper::should_apply_shortcode() ? do_shortcode( $post->post_content ) : $post->post_content;
	$post_content = \preg_replace( '/<!--[\s\S]*?-->/iu', '', $post_content );
	$post_content = wpautop( $post_content );
	$post_content = wp_kses( $post_content, [ 'p' => [] ] );

	// 4. Paragraph with the focus keyword.
	if ( ! empty( $keywords ) ) {
		$regex = '/<p>(.*' . str_replace( [ ',', ' ', '/' ], [ '|', '.', '\/' ], $keywords ) . '.*)<\/p>/iu';
		\preg_match_all( $regex, $post_content, $matches );
		if ( isset( $matches[1], $matches[1][0] ) ) {
			return $matches[1][0];
		}
	}

	// 5. The First paragraph of the content.
	\preg_match_all( '/<p>(.*)<\/p>/iu', $post_content, $matches );
	return isset( $matches[1], $matches[1][0] ) ? wp_html_excerpt( $matches[1][0], 160 ) : '';
});

Hope that helps. Thank you.
