Question

我在本地使用WAMP服务器构建了一个网站，一切正常，然后移植到GoDaddy上的Web服务器，我的重定向功能突然停止工作。

（www.minute.tech）的简单站点，您可以测试我的一个表单，转到form_processing.php，但应该重定向到带有消息的索引页面。当您在失败的重定向后返回索引页面时，它仍会显示＆＃34; Booyah！...＆＃34;的正确消息，并将电子邮件输入我的数据库。

为什么它不能在我的网络服务器上重定向的任何想法，但在我的本地WAMP服务器上会使用相同的代码？干杯！

这是我在sessions.php中的重定向功能：

function redirect_to($new_location) {
header("Location: " . $new_location);
exit();
}

这里是我重定向的process_email.php：

<?php require_once("sessions.php"); ?>
<?php require_once("db_connection.php"); ?>
<?php require_once("functions.php"); ?>

    <?php 

    if(isset($_POST['submit']) && !empty($_POST['email'])){
        //Process form
        $email = $_POST['email'];
        $email = mysql_prep($email);
        $techcheck = (isset($_POST['techcheck'])) ? 1 : 0;

        // 2. Perform database query
        $query  = "INSERT INTO signups (";
        $query .= " email, techcheck";
        $query .= ") VALUES (";
        $query .= "'{$email}', $techcheck";
        $query .= ")";

        $result = mysqli_query($connection, $query);

        if ($result) {
            // Success
            $_SESSION["good_message"] = "Booyah! We will keep you posted on progress.";
            redirect_to("../index.php");
        } else {
            //Failure
            $_SESSION["bad_message"] = "Failed to accept email.";
            redirect_to("../index.php");
        }
    } else {
        //This can be an accidental GET request
        $_SESSION["bad_message"] = "That is not a valid email! Please try again.";
        redirect_to("../index.php");
    }

    ?>

有时你必须为头功能启动对象

将此代码添加到所有页面

<?php ob_start(); ?>

删除所有空格。在标题重定向之前，某些服务器设置可以输出，但绝大多数服务器都不会正确重定向。打开错误报告，它可能会告诉您在重定向之前有输出：

<?php
// ^---- Just do one open tag
require_once("sessions.php"); // Remove close tag, possible empty space after
require_once("db_connection.php"); // Remove close tag, possible empty space after
require_once("functions.php"); // Remove close tag, possible empty space after
// Remove the close and open php tags
if(isset($_POST['submit']) && !empty($_POST['email'])){
        //Process form
        $email = $_POST['email'];
        $email = mysql_prep($email);
        $techcheck = (isset($_POST['techcheck'])) ? 1 : 0;

        // 2. Perform database query
        $query  = "INSERT INTO signups (";
        $query .= " email, techcheck";
        $query .= ") VALUES (";
        $query .= "'{$email}', $techcheck";
        $query .= ")";

        $result = mysqli_query($connection, $query);

        if ($result) {
            // Success
            $_SESSION["good_message"] = "Booyah! We will keep you posted on progress.";
            redirect_to("../index.php");
        } else {
            //Failure
            $_SESSION["bad_message"] = "Failed to accept email.";
            redirect_to("../index.php");
        }
    } else {
        //This can be an accidental GET request
        $_SESSION["bad_message"] = "That is not a valid email! Please try again.";
        redirect_to("../index.php");
    }
// If you have no more content below this point, just remove the close php tag
// it is not required and is a possible source of empty space down the line...

此外，您不应再使用mysql_，它已在PHP 7中弃用并删除。另外，绑定参数而不是将此参数直接放入sql中：

$query .= "'{$email}', $techcheck";

使用JS。

<?php    
function redirect_to($new_location) { ?>

<script>window.location="<?php echo $new_location; ?>";</script>
<?php } ?>

重定向功能不重定向
