请帮助我更新 MySQL

这是我更新记录的代码：

<?php
if ( isset($_GET['id'])) {
    $id = $_GET['id'];
    $sql = mysqli_query($link, "SELECT * FROM changelog WHERE id='".$_GET['id']."'");
    $row = mysqli_fetch_array($sql);
}

if ( isset($_POST['novavsebina'])) {
    $novavsebina = $_POST['novavsebina'];
    $id = $_POST['id'];
    $sql = mysqli_query($link, "UPDATE changelog SET vsebina = '" . $novavsebina . "' WHERE id='".$_POST['id']."', date='".$_POST['date']."'");
    header('Location: changelog.php');
}
?>

<div class="container main">
    <div class="row">
        <div class="page-header">
            <h1>Changelog <small>Urejanje</small></h1>
        </div>

        <form role="form" action="uredi.php" method="post" accept-charset="utf-8">
                <textarea name="novavsebina"><?php echo $row['vsebina']; ?></textarea>
                <input type="hidden" name="id" value="<?php echo $row['id'] ?>">
                <input type="date" name="date" value="<?php echo $row['date']; ?>" placeholder="">
                <button type="submit" style="margin-top: 20px" class="btn btn-primary"><i class="glyphicon glyphicon-plus"></i> Dodaj</button>
        </form> 
    </div>
</div>

当我尝试更新时，它不会更新，甚至不会给我错误...

你得到错误。你只是没有检查它们。

您的查询有语法错误：

"WHERE id='".$_POST['id']."', date='".$_POST['date']."'"

应该

"WHERE id='".$_POST['id']."' AND date='".$_POST['date']."'"
