将变量从一个类传递到另一个类

Question

你好我正在创建一个注册类或类，用户填写表单，第一个类创建用户记录，然后它移动到下一个类，它将所有的细节放在user_individual表。然而，iam无法将第一个类中的一个变量传递给另一个类。 第一个类的$ user_id也需要添加到第二个类的末尾。任何想法如何做到这一点？

include('../../../Connections/pdo.php'); 

/*reg class*/ 
class newreg { 

private $db; 

public function __construct(){ 
    $this->db = new connection(); 
    $this->db = $this->db->dbconnect(); 
} 

public function addusr($username,$password, 
$usrTypeId,$usrFstRegDate, 
$usrStatus, $activated, 
$chgPwd,$fstActivated, 
$lstlogin,$registered){ 

if(!empty($username)){ 

$st = $this->db->prepare(" INSERT INTO users 
(user_name, user_password, 
user_type_id,user_first_registration_date, 
user_status, activated, 
change_password, first_activated, 
last_log_in, registered) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"); 
$st->bindParam(1, $username); 
      $st->bindParam(2, $password); 
      $st->bindParam(3, $usrTypeId); 
      $st->bindParam(4,$usrFstRegDate); 
      $st->bindParam(5, $user_status); 
      $st->bindParam(6, $activated); 
      $st->bindParam(7, $chgPwd); 
      $st->bindParam(8, $fstActivated); 
      $st->bindParam(9, $lstlogin); 
      $st->bindParam(10, $registered); 

      $st->execute(); 
      echo 'Inserted: '; 
      return $this->db->lastInsertId(); 

     } else { 
    echo "Fail"; 
    } 

    } 
    }

-----------------这就是我所谓的类--------

include('../../../includes/class.php'); 

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "add_user_form")) { 


$username = $_POST['username']; 
$password="defpassword"; 
$usrTypeId=1; 
$usrFstRegDate=date_create()->format('Y-m-d'); 
$usrStatus="registered"; 
$activated=0; 
$chgPwd=0; 
$fstActivated="0000-00-00"; 
$lstlogin=0000-00-00; 
$registered=1; 

$obj = new newreg(); 
$obj->addusr($username, $password,$usrTypeId,$usrFstRegDate,$usrStatus,$activated, 
$chgPwd,$fstActivated,$lstlogin,$registered); 


$title = $_POST['title']; 
$firstname = $_POST['firstname']; 
$lastname = $_POST['lastname']; 
$knownAs = $_POST['knownas']; 
$gender = $_POST['gender']; 
$dob = $_POST['dob']; 
$nsn = $_POST['nsn']; 
$email = $_POST['email']; 
$addy1 = $_POST['addy1']; 
$addy2 = $_POST['addy2']; 
$addy3 = $_POST['addy3']; 
$city = $_POST['city']; 
$region = $_POST['region']; 
$postcode= $_POST['postcode']; 
$pnumber= $_POST['pnumber']; 
$wnumber = $_POST['wnumber']; 
$vquestion = $_POST['vquestion']; 
$vanswer = $_POST['vanswer']; 
$usr_ind_id =1; 
$user_type = 1; 
$user_id =; //how to get the return $this->db->lastInsertId(); and add it to user_id 

$obj2 = new individReg(); 
$obj2->addIndivid($title,$firstname,$lastname,$knownAs,$gender,$dob,$nsn,$email,$addy1,$addy2, 
$addy3,$city,$region,$postcode,$pnumber,$wnumber,$vquestion,$vanswer,$user_type,user_id); 

Answer 1

只是使页面newreg :: addusr（）函数返回LAST_INSERT_ID 你的情况，这将是：

return $this->db->lastInsertId(); 

将此代码添加到newreg :: addusr函数结束，最终再通过这个ID来individReg :: addIndivid（）
