Moodle: 查询 / 更新 / 添加 / 删除 / 导出 用户 （$DB用法）
1. 添加用户
Php代码
require_once('config.php'); // config.php under root folder
require_once($CFG->dirroot .'/course/lib.php');
require_once($CFG->libdir .'/filelib.php');
//redirect_if_major_upgrade_required();
$person = new StdClass();
$person->auth = 'manual';
$person->confirmed = 1;
$person->mnethostid = 1;
$person->lastlogin = time();
$person->currentlogin = time();
$person->username = "username";
$person->password = hash_internal_user_password('password');
//$person->idnumber = $person->username;
$person->firstname = "firstname";
$person->lastname = "lastname";
$person->email = "firstname@gmail.com";
$person->city = "sf";
$person->country = "US";
$person->lang = "en";
echo $person->id = $DB->insert_record('user', $person);

2. 查询用户
Php代码
require_once('config.php'); // config.php under root folder
require_once($CFG->dirroot .'/course/lib.php');
require_once($CFG->libdir .'/filelib.php');
//redirect_if_major_upgrade_required();
echo $DB->count_records('user').'
'; // how many users do you have $person = $DB->get_record('user', array('username'=>'my_name')); echo '
'; // how many users do you have $person = $DB->get_record('user', array('username'=>'my_name')); echo '
'; print_r($person);
复制代码
3. 更新用户
Php代码
require_once('config.php');
require_once($CFG->dirroot .'/course/lib.php');
require_once($CFG->libdir .'/filelib.php');
//redirect_if_major_upgrade_required();
$person = new StdClass();
$person->id = 10370;
$person->password = hash_internal_user_password('xinxin123');
$DB->update_record('user', $person);
复制代码
4. 删除用户
Php代码
require_once('config.php');
require_once($CFG->dirroot .'/course/lib.php');
require_once($CFG->libdir .'/filelib.php');
//redirect_if_major_upgrade_required();
$DB->delete_records('user', array('id'=>10546));
复制代码
5. 导出用户
Php代码
require_once('config.php');
require_once('../lib/functions.php');
require_once('../lib/array2xml.php');
$conditions = array();
$sort = 'id desc';
$fields = 'id,username,firstname,lastname,email,lastlogin,lastip';
$limitfrom = 0;
$limitnum = 30;
$students['students'] = objectToArray($DB->get_records('user', $conditions, $sort, $fields, $limitfrom, $limitnum));
//echo ''; print_r($students);
//echo JSON($students);
header( 'Content-Type:text/html;charset=utf-8');
header('Content-type: text/xml');
exit(array2xml($students));
