php, mysqli-stmt.bind-param]:类型定义字符串中的元素数与绑定变量数不匹配

问题描述

    // if the 'id' variable is not set in the URL, we must be creating a new record
    else
    {
            // if the form's submit button is clicked, we need to process the form
            if (isset($_POST['submit']))
            {
                    // get the form data

                            $mtcn = htmlentities($_POST['mtcn'], ENT_QUOTES);
                            $amount = htmlentities($_POST['amount'], ENT_QUOTES);
                            $currency = htmlentities($_POST['currency'], ENT_QUOTES);
                            $sender_name = htmlentities($_POST['sender_name'], ENT_QUOTES);
                            $sender_country = htmlentities($_POST['sender_country'], ENT_QUOTES);
                            $receiver_name = htmlentities($_POST['receiver_name'], ENT_QUOTES);
                            $comment = htmlentities($_POST['comment'], ENT_QUOTES);
                            $support = htmlentities($_POST['support'], ENT_QUOTES);
                            $email = htmlentities($_POST['email'], ENT_QUOTES);

                    // check that mtcn and amount  are both not empty
                    if ($mtcn == '' || $amount == '')
                    {
                            // if they are empty, show an error message and display the form
                            $error = 'ERROR: Please fill in all required fields!';
                            renderForm($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();

运行脚本时出现错误:

警告:mysqli_stmt::bind_param() [mysqli-stmt.bind-param]:数量类型定义字符串中的元素与绑定数不匹配C:wampwwwecords.php 中的变量在第 205 行

警告:mysqli_stmt::execute() [mysqli-stmt.execute]: (HY000/2031):没有为准备好的语句中的参数提供数据C:wampwwwecords.php 第 206 行

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

知道如何修复它吗?我计算了来自 bind_param 的参数，它们对我来说似乎很好......

Any idea how I can fix it ? I counted the parameters from bind_param and they seem fine for me ...

推荐答案

我认为你需要更多的's'-es?

I think you need more 's'-es in this?

 $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)

try this (asuming they're all strings)

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