joomla 2.5数据库未收到查询？

Question

我有php函数，该函数使用db中的模板向用户发送电子邮件。 问题是最后3个查询无法正常工作（我从phpmyadmin尝试过，并且工作正常）。 该代码可以执行，没有错误，但是没有获取足够的视图和答复，而是只有空白（db-> loadobjectlist返回null？），并且最后一个更新查询也不执行任何操作。

这是它最后发送的

请帮助我了解这段代码有什么问题

$mailfrom = $config->get('mailfrom');

    $query = "update ".$dbprefix."users set WeeklyAD=ADDDATE(WeeklyAD, interval 7 day) where id='".$user->id."'";
    $database->setQuery($query);
}

Answer 1

由于loadObjectList()从查询返回的表记录中返回PHP对象的索引数组，因此您似乎在选择查询中使用了错误的函数。 要使用此功能，您可以使用以下方法访问各个值：

$row['index']->name // e.g. $row['2']->email

对于单行结果，请使用loadObject() ，该对象从表中的单个记录返回一个PHP对象。 这与您的代码匹配，因为您可以使用以下方法访问各个值：

$result->index // e.g. $result->email

最终更新查询未执行，因为您缺少execute() 。

$query = "update ".$dbprefix."users set WeeklyAD=ADDDATE(WeeklyAD, interval 7 day) where id='".$user->id."'";
$database->setQuery($query);
$result = $database->execute();
