在Drupal中,我首先序列化出现在私人消息体中的电子邮件,并将其存储为MySQL,如下所示:
function prvtmsg_list($body) {
$notify = array();
if (isset($body->emails)) {
$notify['mid'] = $body->mid;
$notify['emails'] = serialize($body->emails);
}
if (isset($body->vulgar_words) {
$notify['mid'] = $body->mid;
$notify['vulgar_words'] = serialize($message->vulgar_words);
}
if (isset($notify['mid'])) {
drupal_write_record('prvtmsg_notify', $notify);
}
}
当我稍后尝试检索它们时,电子邮件用户化失败,我会像这样检索它们:
function prvtmsg_list_notify() {
// Select fields from prvtmsg_notify and Drupal pm_message tables
$query = db_select('prvtmsg_notify', 'n');
$query->leftJoin('pm_message', 'm', 'n.mid = m.mid');
$query->fields('n', array('mid', 'emails', 'vulgar_words'));
$query->fields('m', array('mid', 'author', 'subject', 'body', 'timestamp'));
orderBy('timestamp', 'DESC');
$query = $query->extend('PagerDefault')->limit(20);
$result = $query->execute()->fetchAll();
$rows = array();
foreach ($result as $notify) {
$rows[] = array(
$notify->author,
$notify->subject,
implode(', ', unserialize($notify->emails)),
implode(', ', unserialize($notify->vulgar_words)),
);
}
$build = array();
$build['table'] = array(
'#theme' => 'table',
'#header' => array(
t('Author'),
t('Message subject'),
t('Emails captured'),
t('Vulgar Words Captured'),
),
'#rows' => $rows,
);
$build['pager']['#theme'] = 'pager';
return $build;
}
也许我序列化电子邮件的方式有误?这是因为:
dpm(unserialize($notify->emails);
给出Array,Array,Array - 这意味着:
Array(
[0] => Array() [1] => Array() [2] => Array() [3] => Array()
)
令人惊讶的是,非序列化的低俗词语显示还可以!我不确定是否可以像这样序列化电子邮件:
$notify['emails'] = serialize (array($body->emails));
我遇到了过去的确切情况,其中反序列化对我不起作用,有些事情我不清楚,我需要学习它。任何人都可以确认或告诉我出了什么问题吗?
N.B。上面的代码来自内存,可能不准确,因为我目前无法访问它。

如果我正确读取这个,你正在将数组写入db
drupal_write_record('prvtmsg_notify', $notify);
应该是:
drupal_write_record('prvtmsg_notify', serialize($notify));
你很可能不再需要
$notify['emails'] = serialize($body->emails);
而且可以写:
$notify['emails'] = $body->emails;
从db中检索它后,你可以反序列化数组并迭代它:
$array = unserialize(someFunctionToGetPrvtmsg_notifyFromTheDb());
//the array should be the same as the one you serialized
