我有以下代码,它工作得很好,我只是想将它转换为live,所以它每10秒更新一次,没有页面刷新,我猜我需要使用AJAX或Jquery但我缺乏知识怎么做

=====VIA <?php include("database.php"); ?>====
<?php
// Create connection
$con=mysqli_connect("ip/host","user","pass","db");
// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>

====ON THE PAGE====
<? php

$result = mysqli_query($con, "SELECT * FROM sql347511.1 ORDER BY ID DESC LIMIT 1;");

while ($row = mysqli_fetch_array($result)) {
    echo "<div class='infobox_data'>Temperature: ".$row['TEMP']."&deg;C</div>";
    echo "<div class='infobox_data'>Humidity: ".$row['HUMID']."%</div>";
    echo "<div class='infobox_time'>Captured: ".date("g:i:s a F j, Y ", strtotime($row["TIME"]))."</div>";
}

mysqli_close($con); ?>

我有一个非常简单的任务要执行，当我以一种方式运行代码时没问题，如果我以另一种方式运行它则致命错误：未捕获的异常“异常”...

作品

if (Input::get('userid')) {

    $user_id = Input::get('userid');

    $user->find($user_id);

    $name = $user->data()->first_name;


    if ($user->data()->active == 1) {

        $user->update(array(
            'active' => 0
        ));

        Session::flash('userboard', $name.' Deactivated');
        Redirect::to('admin.php');

    } else {

        $user->update(array(
            'active' => 1
        ));

        Session::flash('userboard', $name.' Activated');
        Redirect::to('admin.php');

    }

}

不起作用

if (Input::get('adminid')) {

    $user_id = Input::get('adminid');

    $user->find($user_id);

    $name = $user->data()->first_name;

    if ($user->data()->active == 1) {

        $user->update(array(
            'group' => 1
        ));

        Session::flash('userboard', $name.' Deactivated');
        Redirect::to('admin.php');

    } else {

        $user->update(array(
            'group' => 2
        ));

        Session::flash('userboard', $name.' Activated');
        Redirect::to('admin.php');

    }

} …
