So I want to get and return last inserted id from query. I am successfully get the last inserted id but I have a little problem when try to return it to index.php file
This is my method code :
public function InsertUserCard(UserCard $uc)
{
if(!$this->DuplicateUserCard($uc))
{
$stmt = $this->conn->prepare("INSERT INTO ".$this->table_name."
(user_id, card_id, barcode, barcode_format, created_at, updated_at)
VALUES(?, ?, ?, ?, ?, ?)");
if ($stmt == FALSE)
{
die($this->conn->error);
}
else
{
$user_id = NULL;
$card_id = NULL;
$barcode = NULL;
$barcode_format = NULL;
$created_at = NULL;
$updated_at = NULL;
$stmt->bind_param("iissss", $user_id, $card_id, $barcode, $barcode_format, $created_at, $updated_at);
$user_id = $uc->getUserId();
$card_id = $uc->getCardId();
$barcode = $uc->getBarcode();
$barcode_format = $uc->getBarcodeFormat();
$created_at = $uc->getCreatedAt();
$updated_at = $uc->getUpdatedAt();
$stmt->execute();
$result = $this->conn->insert_id; <-- This is how I get the last inserted id
$stmt->close();
}
// Check for successful insertion
if ($result)
{
// User card successfully inserted
return USER_CARD_INSERTED_SUCCESSFULLY;
}
else
{
// Failed to insert user card
return USER_CARD_INSERT_FAILED;
}
}
else
{
return USER_CARD_ALREADY_EXISTED;
}
}
and this is my index.php file
$app->post('/user/card/rev', 'authenticate', function() use ($app)
{
// check for required params
verifyRequiredParams(array('user_id', 'card_id', 'barcode', 'barcode_format', 'created_at', 'updated_at'));
global $user_id;
$response = array();
$timestamp = time();
$now = date("Y-m-d H:i:s", $timestamp);
$uc = new UserCard();
$uc->setUserId($user_id);
$uc->setCardId($app->request->post('card_id'));
$uc->setBarcode($app->request->post('barcode'));
$uc->setBarcodeFormat($app->request->post('barcode_format'));
$uc->setCreatedAt($app->request->post('created_at'));
$uc->setUpdatedAt($app->request->post('updated_at'));
// choose card from db by user
$UserCardDB = new UserCardDB(MySqlDb::getInstance()->connect());
$UserCard = $UserCardDB->InsertUserCard($uc);
if ($UserCard == USER_CARD_INSERTED_SUCCESSFULLY)
{
$response["error"] = false;
$response["message"] = "User Card added successfully";
$response["current_timestamp"] = $timestamp;
$response["current_date"] = $now;
$response["last_inserted_id"] = SHOULD_BE_HERE;
echoRespnse(201, $response);
}
});
as you see, I want to put the last inserted id on $response["last_inserted_id"]
, but I do not know how to do it.
any ideas ?
thanks:)
