[NSFW] FAQ schema stripping URLs

Hi @mesmer7

Thanks for your patience. I just saw your messages, as our Support team doesn’t work over the weekend. I’d be happy to help you.

What you’re seeing is actually expected behavior. Most FAQ schema implementations (including Kadence) sanitize HTML inside the “Answer” field, and often strip attributes like href from <a> tags. This is done to keep the structured data compliant with Google’s guidelines and avoid invalid or potentially unsafe markup.

Try adding this custom code using the code snippets plugin: https://www.kadencewp.com/help-center/docs/kadence-theme/how-to-add-a-custom-filter-or-function-with-code-snippets/

add_filter( 'kadence_blocks_faq_schema_allowed_tags', 'custom_faq_schema_disallow_all_tags', 10, 1 );

function custom_faq_schema_disallow_all_tags( $tags ) {
    // Return an empty string to disallow all HTML tags
    return '';
}

Hi @mesmer7,

Thanks for your patience.

We’ve submitted this to our dev team, as the filter is not working as expected even after implementation.

For now, please use the following custom code as a workaround:

add_filter( 'kadence_blocks_faq_schema_answer', 'custom_kadence_faq_schema_preserve_links', 10, 2 );


function custom_kadence_faq_schema_preserve_links( $answer, $block ) {
    // Define the tags we want to allow (matching your list)
    $allowed_tags_string = '<a><strong><br><h2><h3><h4><h5><ul><li><ol><p>';
    
    // Define specifically which attributes we want to keep for which tags
    $allowed_attributes = array(
        'a' => array(
            'href'   => true,
            'title'  => true,
            'target' => true,
        ),
        // Add other tags here if you need specific attributes like 'class'
    );

    if ( isset( $block['innerBlocks'] ) && is_array( $block['innerBlocks'] ) ) {
        $new_answer = '';

        foreach ( $block['innerBlocks'] as $inner_block ) {
            $block_content = render_block( $inner_block );

            // 1. Remove script and style tags
            $block_content = preg_replace( '@<(script|style)[^>]*?>.*?</\\1>@si', '', $block_content );

            // 2. Use wp_kses to strip tags and attributes safely
            // This is better than strip_tags + preg_replace because it's attribute-aware
            $new_answer .= wp_kses( $block_content, $allowed_attributes + array_fill_keys( 
                explode( '>', str_replace( '<', '', $allowed_tags_string ) ), 
                array() 
            ) );
        }

        return trim( $new_answer );
    }

    return $answer;
}

We’ll keep you posted as soon as we have an update from the team.
