Question

您好我正在尝试实施一项小功能，包括价格检查（现在只是测试！）但是当我点击提交时，没有任何内容可以回复给我！这是我的代码：

＆＃13;

<!doctype html>
<head>
    <meta charset="UTF-8">    
    <title>ValleyRangesPriceCheck</title>
    <link REL='stylesheet' TYPE='text/css' HREF='Style.css'>
</head>
<body>
    <form>
        <input type="date" name="check-in">
        <input type="date" name="check-out">
        <input type="number" name="num-of-guests" min="1" max="10" placeholder="Guests">
        <select name="operator">
            <option>Candelight</option>
            <option>Misty Woods</option>
            <option>Beach Mont</option>
        </select>

        <button type="submit" name="submit" value="submit">submit</button>
    </form>
    <p> The Answer Is:</p>
    <?php
        if (isset($_GET['submit'])){
            $result1 = $_GET['check-in'];
            $result2 = $_GET['check-out'];
            $operator = $_GET['operator'];
                switch ($operator){
                    case "Candelight":
                        echo $result1 + $result2;
                        break;
                }
        }
    ?>
</body>
</html>

感谢您的帮助！

未定义表单方法和操作属性。您应该定义用户数据的发布位置。试试这段代码，

<!doctype html>
<head>
    <meta charset="UTF-8">    
    <title>ValleyRangesPriceCheck</title>
    <link REL='stylesheet' TYPE='text/css' HREF='Style.css'>
</head>
<body>
    <form  method="get" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
        <input type="date" name="check-in">
        <input type="date" name="check-out">
        <input type="number" name="num-of-guests" min="1" max="10" placeholder="Guests">
        <select name="operator">
            <option>Candelight</option>
            <option>Misty Woods</option>
            <option>Beach Mont</option>
        </select>

        <button type="submit" name="submit" value="submit">submit</button>
    </form>
    <p> The Answer Is:</p>
    <?php
        if (isset($_GET['submit'])){
            $result1 = $_GET['check-in'];
            $result2 = $_GET['check-out'];
            $operator = $_GET['operator'];
                switch ($operator){
                    case "Candelight":
                        echo $result1 + $result2;
                        break;
                }
        }
    ?>
</body>
</html>
