Question

我在深度预订系统上工作，我坚持使用标题功能而不是将用户重定向到＆＃39; index.php＆＃39;页。这是我的PHP代码。

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "SELECT * FROM customer WHERE transactionum = '$ticket' ";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        echo  "<strong>".$row["fname"]. " " . $row["lname"]."</strong><br>";
    }
} else {

header('location:index.php');

    }
?></li>
    <li class="list-group-item">Paid: <?php if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "SELECT * FROM customer WHERE transactionum = '$ticket' ";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        echo  "<strong>".$row["paid"]. "</strong><br>";
    }
} else {
    header('location:index.php');
}

//创建连接

    $conn = mysqli_connect($servername, $username, $password, $dbname);
    // Check connection
    if (!$conn) {
        die("Connection failed: " . mysqli_connect_error());
    }

     $sql = "SELECT * FROM customer WHERE transactionum = '$ticket' ";
    $result = mysqli_query($conn, $sql);

    if (mysqli_num_rows($result) > 0) {
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        $test1 =  "<strong>".$row["fname"]. " " . $row["lname"]."</strong><br>";
    }
    } else {

    header('location:index.php');

    }
    ?></li>
    <li class="list-group-item">Paid: <?php if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
    }

    $sql = "SELECT * FROM customer WHERE transactionum = '$ticket' ";
    $result = mysqli_query($conn, $sql);

    if (mysqli_num_rows($result) > 0) {
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        $var1 =  "<strong>".$row["paid"]. "</strong><br>";
    }
    } else {
    header('location:index.php');
    }   
    echo $test1;
    echo $var1;

查看此网址http://php.net/manual/es/function.header.php 使用大写字母

header('Location: http://www.example.com/');

尝试使用此表单并确保代码“else”执行。
