【问题描述】：

问题： 您好，我的一个提交表单有问题。我已经创建了一个数据库，我也创建了一个表。当我已经填写了我的表格，然后单击提交按钮，然后检查 phpmyAdmin。它没有显示我已经提交的详细信息。

这是我的 php 代码，包括 sql connect (reserve.php)

<?php 
    if($_POST['formSubmit'] === "Submit")
    {
        $errorMessage = "";

        if(empty($_POST['formName']))
        {
            $errorMessage .= "<li> You forgot to enter your name! </li>";
        }


        //Doesnt Have List
        $varName = $_POST['formName'];
        $varEmail = $_POST['formEmail'];
        $varPhone = $_POST['formPhone'];
        $varStreet = $_POST['formStreet'];
        $varNumber = $_POST['formNumber'];
        $varCity = $_POST['formCity'];
        $varPostCode = $_POST['formPostCode'];
        $varCountry = $_POST['formCountry'];
        //Have List
        $varPeople = $_POST['formPeople'];
        $varTables = $_POST['formTables'];
        $varTime = $_POST['formTime'];
        $varComment = $_POST['formComment'];

        if(empty($errorMessage))
        {
            //Sql Connect
            $db = mysql_connect ('sql999.byethost9.com','b9_9999999','password');
            if(!$db) die("Error connecting to MySQL database.");
            mysql_select_db('b9_9999999_database',$db);

            $sql = "INSERT INTO form2 (Name, Email, Phone, Street, Number, City, PostCode, Country, People, Tables, Time, Comment) VALUES (".
            //Doesnt Have List Dropdown
            PrepSQL($varName) . ", ".
            PrepSQL($varEmail) . ", ".
            PrepSQL($varPhone) . ", ".
            PrepSQL($varStreet) . ", ".
            PrepSQL($varNumber) . ", ".
            PrepSQL($varCity) . ", ".
            PrepSQL($varPostCode) . ", ".
            PrepSQL($varCountry) . ", ".
            //Have List Dropdown
            PrepSQL($varPeople) . ", ".
            PrepSQL($varTables) . ", ".
            PrepSQL($varTime) . ", ".
            PrepSQL($varComment) . ") ";
            mysql_query($sql);

            header('Location:thankyou.html');
            exit();
              }
        }

        //function:PrepSQL()
        //use stripslashes and mysql_real_escape_string PHP functions
        //tosanitize a string for use in an SQL query
        //
        //also puts single quotes around the string
        //
        function PrepSQL($value)
        {
            //Stripslashes
            if(get_magic_quotes_gpc())
            {
                $value = stripslashes($value);
            }

            //Quote
            $value = "'" . mysql_real_escape_string($value) . "'";

            return($value);
        }
    ?>

这是我的表单代码：

<html>
<?php include("reserve.php"); ?>
<body>
.......

 echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post">

【问题讨论】：

澄清一下，您的问题与 phpMyAdmin 无关。您还应该使用 mysqli_ 函数，或者更好的是 PDO。
It doesnt show the details that I already submitted . 显示了什么？请提出正确的问题。阅读：stackoverflow.com/help/how-to-ask
您的输入名称与您在 php 脚本中使用的变量不匹配。完全没有。
@jeroen 哪一个？是在表单代码里面吗？

【解决方案1】：

您的表单字段名称与您的 serve.php 名称字段不匹配。您更新的代码应该是

<?php 
    if($_POST['formSubmit'] === "Submit")
    {
        $errorMessage = "";

        if(empty($_POST['formName']))
        {
            $errorMessage .= "<li> You forgot to enter your name! </li>";
        }


        //Doesnt Have List
        $varName = $_POST['name'];
        $varEmail = $_POST['email'];
        $varPhone = $_POST['phone'];
        $varStreet = $_POST['street'];
        $varNumber = $_POST['street-number'];
        $varCity = $_POST['city'];
        $varPostCode = $_POST['post-code'];
        $varCountry = $_POST['country'];
        //Have List
        $varPeople = $_POST['arrive'];
        $varTables = $_POST['tables'];
        $varTime = $_POST['time'];
        $varComment = $_POST['comments'];

        if(empty($errorMessage))
        {
            //Sql Connect
            $db = mysql_connect ('sql999.byethost9.com','b9_9999999','password');
            if(!$db) die("Error connecting to MySQL database.");
            mysql_select_db('b9_9999999_database',$db);

            $sql = "INSERT INTO form2 (Name, Email, Phone, Street, Number, City, PostCode, Country, People, Tables, Time, Comment) VALUES (".
            //Doesnt Have List Dropdown
            PrepSQL($varName) . ", ".
            PrepSQL($varEmail) . ", ".
            PrepSQL($varPhone) . ", ".
            PrepSQL($varStreet) . ", ".
            PrepSQL($varNumber) . ", ".
            PrepSQL($varCity) . ", ".
            PrepSQL($varPostCode) . ", ".
            PrepSQL($varCountry) . ", ".
            //Have List Dropdown
            PrepSQL($varPeople) . ", ".
            PrepSQL($varTables) . ", ".
            PrepSQL($varTime) . ", ".
            PrepSQL($varComment) . ") ";
            mysql_query($sql);

            header('Location:thankyou.html');
            exit();
              }
        }

        //function:PrepSQL()
        //use stripslashes and mysql_real_escape_string PHP functions
        //tosanitize a string for use in an SQL query
        //
        //also puts single quotes around the string
        //
        function PrepSQL($value)
        {
            //Stripslashes
            if(get_magic_quotes_gpc())
            {
                $value = stripslashes($value);
            }

            //Quote
            $value = "'" . mysql_real_escape_string($value) . "'";

            return($value);
        }
    ?>

这会解决你的问题
