以下是相关代码(来自IPN页面的代码段):
if($payment_status=='Completed'){
$txn_id_check = mysqli_query($mysqli,"SELECT 'transaction_id' FROM 'payment' WHERE 'transaction_id'='".$txn_id."'");
if(mysqli_num_rows($txn_id_check)!=1){
if($receiver_email=='fortunefilly@hotmail.com'){
if($payment_amount=='9.99' && $payment_currency=='GBP'){
// add txn_id to db
$query = "INSERT INTO payment (transaction_id, payment_status, users_id) VALUES(?, ?, ?)";
$statement = $mysqli->prepare($query);
$statement->bind_param('sss',$txn_id, $payment_status,$id);
if($statement->execute()){
print 'Success! ID of last inserted record is : ' .$statement->insert_id .'<br />';
}else{
die('Error : ('. $mysqli->errno .') '. $mysqli->error);
}
$statement->close();
// update premium to 1
$update_premium = mysqli_query("UPDATE 'users' SET is_member ='1' WHERE 'id' ='".$id."'");
}
}
}
}
正如您所看到的,我正在关注paypals示例代码给我的评论。
插入数据库时出现问题但不确定问题。
