PHP : User update method inside insert Method - php

Question

I have a little problem when I try to validating the condition in my insert method.
This is what I want :
if data not exist, do insert data
if data exist in 'isActive' is 'true', send error 'data already exist'
if data exist in 'isActive' is 'false', run update method
But it seems my method can not run smoothly.
this is my insert method :
public function InsertUserCard(UserCard $uc)
{
//get kartu
$user_card = $this->GetUserCardByCardIdByUserId($uc);
if(!$user_card)
{
$stmt = $this->conn->prepare("INSERT INTO ".$this->table_name."
(user_card_id, user_id, card_id, card_number, barcode, barcode_format, created_at, updated_at)
VALUES('', ?, ?, ?, ?, ?, ?, ?)");
if ($stmt == FALSE)
{
die($this->conn->error);
}
else
{
$user_id = NULL;
$card_id = NULL;
$card_number = NULL;
$barcode = NULL;
$barcode_format = NULL;
$created_at = NULL;
$updated_at = NULL;
$stmt->bind_param("iisssss", $user_id, $card_id, $card_number, $barcode, $barcode_format, $created_at, $updated_at);
$user_id = $uc->getUserId();
$card_id = $uc->getCardId();
$card_number = $uc->getCardNumber();
$barcode = $uc->getBarcode();
$barcode_format = $uc->getBarcodeFormat();
$created_at = $uc->getCreatedAt();
$updated_at = $uc->getUpdatedAt();
$stmt->execute();
$result = $this->conn->insert_id;
$stmt->close();
}
// Check for successful insertion
if ($result)
{
// User card successfully inserted
return $result;
}
else
{
// Failed to insert user card
return USER_CARD_INSERT_FAILED;
}
}
else if($user_card->getisActive() == 'true')
{
return USER_CARD_ALREADY_EXISTED;
}
else {
// this is where I try to run the update method
$uc->setUserCardId($user_card->getUserCardId());
$this->UpdateUserCard($uc);
return $uc->getUserCardId();
}
}
in last condition, I try to run the update method if the data is exists but 'isActive' value is 'false'
This is my update method :
public function UpdateUserCard(UserCard $uc)
{
$stmt = $this->conn->prepare("UPDATE ".$this->table_name."
SET user_id = ?,
card_id = ?,
card_number = ?,
barcode = ?,
barcode_format = ?,
isActive = ?,
updated_at = ?
WHERE user_card_id = ?
AND user_id = ?");
if($stmt == FALSE)
{
die($this->conn->error);
}
else
{
$user_id = NULL;
$card_id = NULL;
$card_number = NULL;
$barcode = NULL;
$format = NULL;
$isActive = NULL;
$updated_at = NULL;
$user_card_id = NULL;
$stmt->bind_param("iisssssii", $user_id,
$card_id,
$card_number,
$barcode,
$format,
$isActive,
$updated_at,
$user_card_id,
$user_id);
$user_id = $uc->getUserId();
$card_id = $uc->getCardId();
$card_number = $uc->getCardNumber();
$barcode = $uc->getBarcode();
$format = $uc->getBarcodeFormat();
$isActive = $uc->getisActive();
$updated_at = $uc->getUpdatedAt();
$user_card_id = $uc->getUserCardId();
$stmt->execute();
$num_affected_rows = $stmt->affected_rows;
$stmt->close();
return $num_affected_rows > 0;
}
// Check for successful insertion
if ($stmt->execute())
{
// User card successfully inserted
return USER_CARD_INSERTED_SUCCESSFULLY;
}
else
{
// Failed to insert user card
return USER_CARD_INSERT_FAILED;
}
}
and the last is my GetUserCardByCardIdByUserId Method :
private function GetUserCardByCardIdByUserId(UserCard $card)
{
$stmt = $this->conn->prepare("SELECT user_card_id, user_id, card_id, card_number, barcode, barcode_format, isActive, created_at, updated_at
FROM ". $this->table_name ."
WHERE card_id = ? AND user_id = ?");
if ($stmt == FALSE)
{
die($this->conn->error);
}
else
{
$card_id = NULL;
$user_id = NULL;
$stmt->bind_param("ii", $card_id, $user_id);
$card_id = $card->getCardId();
$user_id = $card->getUserId();
$stmt->execute();
$stmt->bind_result($user_card_id,
$user_id,
$card_id,
$card_number,
$barcode,
$barcode_format,
$isActive,
$created_at,
$updated_at);
$stmt->store_result();
$num_rows = $stmt->num_rows;
if($num_rows != 1)
return NULL;
else {
$card = new UserCard();
$card->setUserCardId($user_card_id);
$card->setUserId($user_id);
$card->setCardId($card_id);
$card->setBarcode($barcode);
$card->setBarcodeFormat($barcode_format);
$card->setisActive($isActive);
$card->setCreatedAt($created_at);
$card->setUpdatedAt($updated_at);
$stmt->close();
return $card;
}
}
}
please check my method if I write wrong structure of code.
thanks :)
