We create content in Drupal and link it to Civi event pages using a Computed Field that matches Event Name to the node's Title field, and Event Start Date to the node's Event Date field. Sample code for the Computed Field:
list($id, $vid, $bundle) = entity_extract_ids($entity_type, $entity);
$query = "SELECT
ce.id
FROM {node} n
INNER JOIN {field_data_field_event_date} de ON n.nid = de.entity_id AND n.vid = de.revision_id
INNER JOIN {civicrm_event} ce ON n.title = ce.title COLLATE utf8_unicode_ci
AND ce.start_date = convert_tz(field_event_date_value,'GMT','America/New_York')
WHERE n.nid = :nid
AND n.vid = :vid
LIMIT 1";
$result = db_query($query,
array(':vid' => $vid, ':nid' => $id))->fetchField(0);
if ($result === NULL || $result == "")
{
$entity_field[0]['value'] = 0;
}
else
{
$entity_field[0]['value'] = $result;
}
Then you can use a bit of display code like this:
if ($entity_field_item['value'] == 0)
{
$display_output = '';
}
else
{
$display_output = '<a href="https://examplesite.org/civicrm/event/register?reset=1&id=' . $entity_field_item['value'] . '">Buy tickets</a>';
}
Since we have the Civi event code saved to the node, we can also use any native Drupal search or Views functionality, and get creative in Drupal templates as needed. Other options could be to write your own module that does something like this, or consider using the Civi REST endpoint /sites/all/modules/civicrm/extern/rest.php?entity=Event&action=getlist&json={"sequential":1}&api_key=yoursitekey&key=yourkey
with Drupal Feeds and Feeds Extensible Parsers modules for a solution that creates and updates the Drupal events with minimal code required.
