Drupal 7 db_update与foreach循环

Question

我有Drupal 7网站与表events_times。我需要检查数据库中是否存在任何记录。如果他们这样做，我想要做一个更新而不是一个插入。我一直在修改代码，但无法使其工作。我收到以下错误：

Fatal error: Call to undefined method UpdateQuery::values() 

这里是我的代码：

$times_values= array(); 

foreach ($form_state['values']['times_fieldset']['registration_times'] as $time) { 
$times_values[] = array('event_id' => $eventId, 
'registration_times' => $time, 
'max_attendees' => 0 
); 
} 
//Check to see if values exist in the table already 
$exists = db_select('events_times','et') 
->fields('et') 
->condition('event_id',$event->id,'=') 
->execute() 
->fetchAll(); 

if ($exists == FALSE) { 
$query = db_insert('events_times')->fields(array('event_id', 'registration_times', 'max_attendees')); 
foreach ($times_values as $record) { 
$query->values($record); 
} 
$query->execute(); 
} 
else { 
$query = db_update('events_times')->fields(array('event_id', 'registration_times', 'max_attendees')); 
foreach ($times_values as $record) { 
$query->values($record); 
} 
$query->execute(); 
} 

Answer 1

Drupal的db_update()和db_insert()使用fields()方法来定义您的值应该结束了。为了支持多个插入对象，并且还通过values()方法接受值。

$query->fields(array(
    'registration_times' => $values['registration_times'], 
);
