Question

我试过制作以下代码。我想将日期，日期，时间，全天候添加到我的数据库中。但是当我选择表单中的值时，我的数据库中没有注册任何内容。它与mysql连接成功。

代码在这里：

<html>

<head>

</head>

<body>

    <form method="post">
        <h3>Add your worktime to database</h3><br>
            <input type="date" name="date"><br><br>
            <input type="text" name="day"><br>
            <input type="time" name="fromtime">
            <input type="time" name="totime">
            <input type="submit" value="submit"><br><br>
    </form>


</body>

<?php
$username = "root";
$password = "root";
$hostname = "127.0.0.1:3306"; 

//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password) 
 or die("Unable to connect to MySQL");
echo "Connected to MySQL<br><br>";

//select a database to work with
$selected = mysql_select_db("danskebank",$dbhandle) 
  or die("Could not select examples");

$date = $_POST['date'];
$day = $_POST['day'];
$fromtime = $_POST['fromtime'];
$totime = $_POST['totime'];

$sql = "INSERT INTO addWorkTime(date, day, fromtime, totime) VALUES('$date', '$day', '$fromtime', 'totime')";


//execute the SQL query and return records
$result = mysql_query("SELECT date, day, fromtime, totime FROM addWorkTime");

//fetch tha data from the database 
while ($row = mysql_fetch_array($result)) {
   Print"<h3>Return from database:</h3>";
   echo "Date: ".$row{'date'}."<br>"."Day: ".$row{'day'}."<br>"."From Time: ".$row{'fromtime'}."<br>"."To Time: ".$row{'totime'}; //display the results
}


?>

RoyalBG是正确的，您需要在代码中的行$result = mysql_query($sql);正确运行插入行。此外，您应该阅读SQL注入，因为您当前编写的代码极易受到SQL注入攻击。
