The onCalendarDetailsFormat handler is called on an array of $vars
containing all of the variables about to be substituted into a calendar event details view (in your theme, that’s the component lw_cal_event_details.html).
Using this handler you can overwrite existing variables, or create your own as in the example below.
<?php
$_LW->REGISTERED_APPS['my_app']=[
'title'=>'My App',
'handlers'=>['onCalendarDetailsFormat'],
];
class LiveWhaleApplicationMyApp {
public function onCalendarDetailsFormat($vars) {
global $_LW;
if (!empty($vars['tags_calendar'])) {
// if event has tags, add a {related_events} variable that shows events
// which share any of those tags (excluding the current event)
$vars['related_events']=$_LW->widgetEval('<widget type="events">
<arg id="tag">'.implode('</arg><arg id="tag">', $vars['tags_calendar']).'</arg>
<arg id="tag_mode">any</arg>
<arg id="filter" name="id" action="not_equals">' . $vars['id'] . '</arg>
</widget>');
};
return $vars;
}
}
?>
The above example would be paired with the following change to the calendar component lw_cal_event_details.html. The if
statement here is important, since obj.related_events
might not always have a value.
{[ if (obj.related_events) { ]}
<div id="lw_cal_event_related_events">
<h3>Related Events:</h3>
{{ related_events }}
</div>
{[ } ]}
