同时有两个 php 个文件

Question

我正在尝试制作一个网站。 So this is the index.php page. 当单击任何表单的 'more info' 时，用户将被重定向到 payment.php 页面，用户必须在该页面进行付款。付款完成后，用户将被重定向到 success.php 页面，该页面应该是 show these 3 lines for two seconds and then redirect the user to details.php page. However, for some reason, instead of redirecting to details.php, both details.php and index.php come up simultaneously like this。我怎样才能避免索引文件也在那里？我只想显示详细信息文件。

成功页面代码如下：

<?php
include 'index.php';

if(!empty($_GET['tid'] && !empty($_GET['product']))) {
  $GET = filter_var_array($_GET, FILTER_SANITIZE_STRING);

  $tid = $GET['tid'];
  $product = $GET['product'];
} else {
  header('Location: payment.php');
}
?>

<!DOCTYPE html>

<title>Thank You</title>
</head>
<body>
<div class="container mt-4">
  <h2>Thank you for purchasing <?php echo $product; ?></h2>
  <hr>
  <p>Your transaction ID is <?php echo $tid; ?></p>
  <p>Check your email for more info</p>
  <?php header('Refresh: 2; URL=details.php?id='.$customer['id']);?>
</div>
</body>
</html>

我觉得这是success.php代码中最重要的部分：

  <?php header('Refresh: 2; URL=details.php?id='.$customer['id']);?>

这里是详情页：

<?php
include 'config/db_connect.php';
include 'config/db.php';
include 'index.php';
if (isset($_POST['delete'])) {
    $id_to_delete = mysqli_real_escape_string($conn, $_POST['id_to_delete']);

    $sql = "DELETE FROM customers WHERE id = $id_to_delete";

    if (mysqli_query($conn, $sql)) {
        header('Location: index.php');
    } else {
        echo 'query error: ' . mysqli_error($conn);
    }
}
// check GET request id param
if (isset($_GET['id'])) {
    // escape sql chars
    $id = mysqli_real_escape_string($conn, $_GET['id']);
    // make sql
    $sql = "SELECT * FROM customers WHERE id = $id";
    // get the query result
    $result = mysqli_query($conn, $sql);
    // fetch result in array format
    $customer = mysqli_fetch_assoc($result);
    mysqli_free_result($result);
    //mysqli_close($conn);
}
?>
<!DOCTYPE html>
<html>
<?php include 'templates/header.php'; ?>
<div class="container center grey-text">
    <?php if ($customer) : ?>
        <h4><?php echo $customer['Job_Type']; ?></h4>
        <p>Contact Number of loan enquirer: <?php echo $customer['Telephone']; ?></p>
        <p>Annual income: <?php echo 12 * $customer['Monthly_salary']; ?></p>
        <p>Existing loan amount: <?php echo $customer['Existing_loan_amount']; ?></p>
        <p>Residential_Type: <?php echo $customer['Residential_Type']; ?></p>
        <p>Job: <?php echo $customer['Job']; ?></p>
        <p>Form submission time: <?php echo date($customer['Form_Submission_Time']); ?></p>
        <!-- DELETE FORM -->
        <form action="details.php" method="POST">
            <input type="hidden" name="id_to_delete" value="<?php echo $customer['id']; ?>">
            <input type="submit" name="delete" value="Delete" class="btn brand z-depth-0">
        </form>
    <?php else : ?>
        <h5>No such customer exists.</h5>
    <?php endif ?>
</div>
<?php include 'templates/footer.php'; ?>

</html>

Answer 1

您的详细信息页面以这三行开头：

include 'config/db_connect.php';
include 'config/db.php';
include 'index.php';

如您所见，在第三行中包含 index.php。我最好的猜测是这就是您在详细信息页面中看到它的原因。
