Display 'today' or 'tomorrow' in event listings

Hi Chris!

You need to use the wpt/event/startdate filter.

See https://github.com/slimndap/wp-theatre/blob/master/functions/wpt_event.php#L1259

Thanks a lot!

Can you tell me how I convert $startdate to another date format, so that I can write a conditional statement to see if the event date matches the current date?

Also, can you control the date format through the filter? I can add a date format to the placeholder in the shortcode on my page, but it looks like that overrides anything I put in the filter.

You can use $event->datetime() to get a timestamp value that you can use for comparisons.

Thanks, Jeroen. I think I’m nearly there, but I’ve still got two problems.

1. I can’t seem to get $event->datetime() to work properly. This is how I used it in my theme functions file: $eventdate = date('Y-m-d',$event->datetime());. It generated this error: ‘Call to a member function datetime() on a non-object in […]functions.php’.

As an experiment, I tried adding the code directly to theatre/functions/wpt_event.php, just to see if I could make it work. This is what I used:

$eventdate = date('Y-m-d',$this->datetime());
$today = date( 'Y-m-d' );

And then I added conditional statements using the two variables to compare dates. It worked fine. But, of course, I want to leave my core files untouched and use the filter to modify the original function in my functions.php file instead. If I simply transfer the code above to my functions.php file, I generate this error: ‘Using $this when not in object context in […]functions.php’.

2. When I made it work by temporarily hacking wpt_event.php, I noticed that filtering $startdate also affected instances where I’d used {{dates}} elsewhere on my site. It looks like $startdate is used to determine $dates in wpt_production.php. I would prefer not to apply the same filter to {{dates}}. To avoid that, could I write a completely new function and create a new filter (for example {{day}}) without hacking the core plugin files?

If not, I’ll have to use a conditional statement to restrict the filter to my homepage. Although there are still a couple of instances of {{dates}} on my homepage that would be affected, I think they’re ones I could live with.

Any advice would be gratefully received. Thanks for your patience!

Chris

Try something this in your functions.php:

function wpt_reformat_day($value, $field, $event) {
  // set the value of the {{day}} placeholder to the start date.
  $value = $event->startdate();

  $eventdate = date('Y-m-d',$event->datetime());
  $today = date( 'Y-m-d' );

  // Add your conditionals here to replace $value with 'today' or 'tomorrow'.

  return $value;
}
add_filter('wpt_event_day', 'wpt_reformat_day', 10, 3);

This code will add

Fantastic. That works perfectly. Thanks so much!

I have also a question with this, how a get weekday before our date such as: wo.21-09-2016 or vrij.27.11.2016?

Thanks Anyway!
