Question

我正在尝试创建目标网页，应该有一个下载按钮。因此，当单击按钮并且表单已正确完成时，用户将被重定向到感谢页面，但是当表单未正确完成时，我会将用户重定向到错误页面。我怎么能意识到这一点？

我的表格代码：

    <form method="post" action="index.php">
    <input type="email" name="iptEmail" placeholder="MaxMustermann@gmail.com" required />
    <br /><br />
    <img id="captcha" src="/securimage/securimage_show.php" alt="CAPTCHA Image" />
    <a href="#" onclick="document.getElementById('captcha').src = '/securimage/securimage_show.php?' + Math.random(); return false"><img src="img/reloadCaptcha.png" alt="reloadCaptcha.png"></a>
    <br /><br />
    <input type="text" name="captcha_code" id="iptCaptcha" placeholder="Code" size="10" minlength="6" maxlength="6" required />
    <br /><br />
    <button name="btnSubmit">DOWNLOAD</button> 
    <?php
    include_once $_SERVER['DOCUMENT_ROOT'] . '/securimage/securimage.php';
    $securimage = new Securimage();
    if(array_key_exists('btnSubmit',$_POST)){
        if ($securimage->check($_POST['captcha_code']) == false) {
            $_SESSION['status'] = "error";
        } else {
            if(isset($_POST['btnSubmit'])){
                $mailKunde = $_POST['iptEmail'];
                $betreff = "";
                $message = "";
                $absName = "";
                $absMail = "";
                $replyTo = "";
                $anhang = "./data/test.zip";
                mail_att($mailKunde, $betreff, $message, $absName, $absMail, $replyTo, $anhang);
                $_SESSION['status'] = "thanks";
            }
        }
    }
    ?>
</form>

我的身体代码：

    <body>
    <?php
    if ($_SESSION['status'] == "home") {
        include('php/home.php');
    } elseif ($_SESSION['status'] == "error") {
        include('php/error.php');
    } elseif ($_SESSION['status'] == "thanks") {
        include('php/thanks.php');
    }
    ?>
</body>

考虑以下情况，您可以使用以下代码行将用户重定向到其他页面：

<?php
if(some_condition...){
    header("Location: someotherplace.php");
}

另外，如果您已经在此行之前发送了html输出，则只需发出javascript重定向：

<?php
if(some_condition...){
    echo("<script>;location.href='someotherplace.php';</script>");
}

PHP按钮单击调用不同的页面
