Reply To: Upvote/Downvote System using ACF Pro

I only use it to ‘upvote’ FAQ posts, not downvote, so only the upvote part is here but I think you get the idea and can create the downvote, based of this. Plus the output is written in twig instead of php but that’s not an issue I think.

Code in template (code is as is)

<div class="faq__helpful">
    <h4>{{ __( 'Was this helpful', 'textdomain' ) }} ?</h4>
    <div>
        <form class="faq_helpful" action="" method="post">
            <input type="hidden" name="post_id" value="{{ post.ID }}" />
            <input type="hidden" name="sd_faq__nonce" value="{{ function( 'wp_create_nonce', 'sd-faq-nonce' ) }}" />
            <button type="submit" name="helpful_yes" value="1" class="button item__delete-submit">
                {{ __( 'YES', 'textdomain' ) }}
            </button>
            {% if helpful_yes %}
                &nbsp;&nbsp;
                <small>{{ _n( '%s person found this helpful', '%s people found this helpful', helpful_yes, 'textdomain')|format(helpful_yes) }}</small>
            {% endif %}
        </form>
    </div>
</div>

if ( isset( $_POST[ "sd_faq__nonce" ] ) ) {
    if ( wp_verify_nonce( $_POST[ "sd_faq__nonce" ], 'sd-faq-nonce' ) ) {

        // add helpful counter
        if ( isset( $_POST[ "helpful_yes" ] ) && '1' == $_POST[ "helpful_yes" ] ) {
            $faq_id = get_the_ID();
            if ( $hf_yes == false ) {
                update_post_meta( $faq_id, 'sd_helpful_yes', '1' );
            } else {
                $hf_yes = $hf_yes + 1;
                update_post_meta( $faq_id, 'sd_helpful_yes', $hf_yes );
            }
        }
    }
}

Since this is not an ACF issue/topic I don’t wanna get too deep into this. WordPress.stackexchange.com is a better place for all WP questions.
