Dear Olly,
I’d need these opening hours:

Delivery
19:00-20:00 and 20:00-21:00 six day [0][1][2][4][5][6]
and 12:00-13:00 and 13:00 – 14:00 sunday and saturday [0][6]

Pick-up
12:00-22:00 every day [0][1][2][4][5][6]

Wednesday closed [3]

I set in WPPizza Open Page this:

then I added to theme functions (wp-content/themes/x-child/functions.php) following lines:

add_action('wppizza_on_pickup_delivery_change', 'myprefix_openinghours_on_pickup');
function myprefix_openinghours_on_pickup($is_pickup){
global $wppizza_options;
/* change opening times if pickup is selected */
if($is_pickup){
/* mondays */
$wppizza_options['openingtimes']['opening_times_standard'][1]['open'] = '12:00';
$wppizza_options['openingtimes']['opening_times_standard'][1]['close'] = '22:00';
/* tuesdays */
$wppizza_options['openingtimes']['opening_times_standard'][2]['open'] = '12:00';
$wppizza_options['openingtimes']['opening_times_standard'][2]['close'] = '22:00';
/* wednesdays */
$wppizza_options['openingtimes']['opening_times_standard'][3]['open'] = '00:00';
$wppizza_options['openingtimes']['opening_times_standard'][3]['close'] = '00:00';
/* thursdays */
$wppizza_options['openingtimes']['opening_times_standard'][4]['open'] = '12:00';
$wppizza_options['openingtimes']['opening_times_standard'][4]['close'] = '22:00';
/* fridays */
$wppizza_options['openingtimes']['opening_times_standard'][5]['open'] = '12:00';
$wppizza_options['openingtimes']['opening_times_standard'][5]['close'] = '22:00';
/* saturdays */
$wppizza_options['openingtimes']['opening_times_standard'][6]['open'] = '12:00';
$wppizza_options['openingtimes']['opening_times_standard'][6]['close'] = '22:00';
/* sundays */
$wppizza_options['openingtimes']['opening_times_standard'][0]['open'] = '12:00';
$wppizza_options['openingtimes']['opening_times_standard'][0]['close'] = '22:00';
}
}
add_filter('wppizza_filter_force_pickup_toggle_display', 'my_prefix_force_pickup_toggle');
function my_prefix_force_pickup_toggle(){
return true;
}

But at toggle Pickup / Delivery order page pickup hours are the same of delivery.

Could You help me please?

Thanks!
