[property_details] shortcode output

[dreamwhisper]

Chris Cree shared code to hide empty fields in the [property_details] shortcode for single listing page. So, for example, if Basement isn't filled in, it isn't output in the shortcode.

    function property_details_shortcode( $atts ) {

        global $post;

        $output = '';

        $output .= '<div class="property-details">';

        $output .= '<div class="property-details-col1">';
            foreach ( (array) $this->property_details['col1'] as $label => $key ) {
                $value = get_post_meta($post->ID, $key, true);
                if ( !empty( $value ) ) {
                    $output .= sprintf( '<b>%s</b> %s<br />', esc_html( $label ), esc_html( get_post_meta($post->ID, $key, true) ) );
                }   
            }
        $output .= '</div><div class="property-details-col2">';
            foreach ( (array) $this->property_details['col2'] as $label => $key ) {
                $value = get_post_meta($post->ID, $key, true);
                if ( !empty( $value ) ) {
                    $output .= sprintf( '<b>%s</b> %s<br />', esc_html( $label ), esc_html( get_post_meta($post->ID, $key, true) ) );
                }   
            }
        $output .= '</div><div class="clear">';
            $output .= sprintf( '<p><b>%s</b><br /> %s</p></div>', __( 'Additional Features:', 'apl' ), get_the_term_list( $post->ID, 'features', '', ', ', '' ) );

        $output .= '</div>';

        return $output;

    }
