Calendar Event Deduplication

Thank you. I have found snippets of php like these but so far they haven’t worked, I think largely because they are just hypothetical. Can you suggest how I might hook into your plugin to implement something like this?

Thanks again.

add_filter(‘hycal_events’, function($events) {
$unique = [];
$output = [];

foreach ($events as $event) {
    // Create a unique key based on title + start date
    $key = md5($event['title'] . $event['start']);

    if (!isset($unique[$key])) {
        $unique[$key] = true;
        $output[] = $event;
    }
}

return $output;

});

/**

• Prevent duplicate events in Hydrogen Calendar Embeds
• Place this in your theme’s functions.php or a custom plugin.
  */

// Hook into Hydrogen Calendar Embeds event filter
add_filter(‘hydrogen_calendar_events’, ‘my_remove_duplicate_calendar_events’);

function my_remove_duplicate_calendar_events($events) {
if (!is_array($events)) {
return $events; // Safety check
}

$unique = [];
$filtered = [];

foreach ($events as $event) {
    // Create a unique key based on UID + start date
    // Adjust keys if your ICS feed uses different field names
    $uid   = isset($event['uid']) ? $event['uid'] : '';
    $start = isset($event['start']) ? $event['start'] : '';

    $key = md5($uid . '|' . $start);

    if (!isset($unique[$key])) {
        $unique[$key] = true;
        $filtered[] = $event;
    }
}

return $filtered;

}
