当用户点击保存按钮时，我正试图将表单中的数据插入数据库，但我收到了以下错误消息：
注意：未定义的索引：在第5行的C:''moodleFile''server''moodle''local''try''process.php中的名称
注意：第6行C:''moodleFile''server''moodle''local''try''process.php中的未定义索引：university_id
致命错误：在第15行的C:''moodleFile''server''moodle''local''try''process.php中的非对象上调用成员函数insert_record（）
这些是当用户点击保存按钮时调用的文件代码：
<?php
global $DB;
$name = $_POST['name'];
$uni_id = $_POST['university_id'];
$record1 = new stdClass();
$record1->name = $name;
$record1->displayorder = '10000';
$record2 = new stdClass();
$record2->name = $uni_id;
$record2->displayorder = '10000';
$records = array($record1, $record2);
$lastinsertid = $DB->insert_record('tbl_faculty', $records);
if(!$lastinsertid)
{
echo "Could not insert";
}
?>
我是Moodle的新手，有人能帮我吗？谢谢
