Drupal获取当前用户信息，密码验证，用户整合

Drupal 获取当前用户信息同样很简单 只需要使用 

global $user;

用户信息：


global $user;
$username = $user->name;
$password = $user->pass;

Drupal数据库查询语句：


//数组形式
sql = "select * from {chat_config} where id='1'";
$rs = db_query($sql);
$chat_Config = $rs->fetchAssoc();


//对象形式
$roleadmin = db_query("select rid from {role} where name = 'administrator'");
$role = $roleadmin->fetchObject();

Drupal密码验证：


require_once DRUPAL_ROOT . '/' . variable_get('password_inc', 'includes/password.inc');
$usertable = "{users}";
$username_field = "name";
$password_field = "pass";
$email_field = "mail";
$uid_field = "uid";


$username = isset($_GET['username']) ? trim(urldecode($_GET['username'])) : '';
$username = mysql_escape_string($username);
$sql = "SELECT " . $username_field ." , ". $password_field . ", ". $email_field . ", ". $uid_field . " FROM " . $usertable . " WHERE ". $username_field . " = '" . str_replace("\\'", "''", $username) . "'";
if($result = db_query($sql)){
  if($row = $result->fetchObject()){
    if(user_check_password($password,$row)){
      //验证成功
    }else{
      //验证失败
    }
  }
}else{
  //没有结果
}

Drupal获取当前用户是否为管理员


//需要有用户ID(uid)
$roleadmin = db_query("select rid from {role} where name = 'administrator'");
$role = $roleadmin->fetchObject();
$rolequry = db_query("select * from {users_roles} where uid = '". $row->uid ."' and rid = '". $role->rid ."'");
$roleset = $rolequry->fetchObject();
if(!empty($roleset)){
  //是管理员
}else{
  //不是管理员
}
