Question

我正在尝试将$ data ['id']的值分配给这样的变量：

$totalfor = $data['id'];

但这不起作用，该值未传递到$ totalfor

如果我回显$data['id']，它给出的正确值为85

我需要$data['id']的值才能将其用于Select查询

有人知道实现此目标的正确语法吗？谢谢

代码如下：

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "test";  

$jury = get_active_user('accountname'); 
$totalfor =  $data['id'];

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT total AS total FROM votestepone WHERE votefor = '$totalfor' AND votedby= '$jury'";
$result = $conn->query($sql);                       
if ($result = mysqli_query($conn, $sql)) {
    while ($row = mysqli_fetch_assoc($result)) {
        $totalvote = $row["total"];
    }
} else {
    echo "0 results";
}

?>

<?php echo $totalvote; ?>

错误是：未定义变量：totalvote

如果我设置 $ totalfor = 85; ->有效但我需要使用来自$ data ['id'];

的值

我在查看页面中，$ data ['id']来自：

$data = $this->view_data;

如果我<?php echo $data['id']; ?>显示85

从$ data ['id']赋值；
