Make it so that all time slots in a time-based booking in WooCommerce Bookings shows how many spots remain, not just partially booked blocks.

rewrite-wc-bookings-get-time-slots-html.php

<?php // do not copy this line

function rewrite_wc_bookings_get_time_slots_html( $block_html, $available_blocks, $blocks ) {
	$block_html       = '';

	foreach ( $available_blocks as $block => $quantity ) {
		if ( $quantity['available'] > 0 ) {

				$block_html .= '<li class="block" data-block="' . esc_attr( date( 'Hi', $block ) ) . '"><a href="#" data-value="' . date( 'c', $block ) . '">' . date_i18n( get_option( 'time_format' ), $block ) . ' <small class="booking-spaces-left">(' . sprintf( _n( '%d left', '%d left', $quantity['available'], 'woocommerce-bookings' ), absint( $quantity['available'] ) ) . ')</small></a></li>';
		}
	}

	return $block_html;
}
add_filter( 'wc_bookings_get_time_slots_html', 'rewrite_wc_bookings_get_time_slots_html', 10, 3 );

HI there,
