    // if the 'id' variable is not set in the URL, we must be creating a new record

                    // get the form data

                            // if they are empty, show an error message and display the form

                            renderForm($mtcn, $amount, $currency, $sender_name, $sender_country, $receiver_name, $comment, $support, $email, $error);
                    }
                    else
                    {
                            // insert the new record into the database
                            if ($stmt = $mysqli->prepare("INSERT date (mtcn, amount, currency, sender_name, sender_country, receiver_name, comment, support, email) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)"))
                            {
                                    $stmt->bind_param("ss", $mtcn, $amount, $currency, $sender_name, $sender_country, $receiver_name, $comment, $support, $email);
                                    $stmt->execute();
                                    $stmt->close();
                            }
                            // show an error if the query has an error
                            else
                            {
                                    echo "ERROR: Could not prepare SQL statement.";
                            }

                            // redirec the user
                         //   header("Location: view.php");
                    }

            }
            // if the form hasn't been submitted yet, show the form
            else
            {
                    renderForm();
            }
    }

    // close the mysqli connection
    $mysqli->close();

当我运行脚本时,我收到错误：

 Warning: mysqli_stmt::bind_param() [mysqli-stmt.bind-param]: Number of elements in type definition string doesn't match number of bind variables in C:\wamp\www\records.php on line 205

Warning: mysqli_stmt::execute() [mysqli-stmt.execute]: (HY000/2031): No data supplied for parameters in prepared statement in C:\wamp\www\records.php on line 206

知道如何解决它吗？我计算了bind_param中的参数,它们对我来说似乎很好……

解决方法:

我觉得你需要更多的东西吗？

 $stmt->bind_param("ss", $mtcn, $amount, $currency, $sender_name, $sender_country, $receiver_name, $comment, $support, $email);

试试这个(假设它们都是字符串)

 $stmt->bind_param("sssssssss", $mtcn, $amount, $currency, $sender_name, $sender_country, $receiver_name, $comment, $support, $email);
