Question

我必须更新订单表中的某些行。

我的代码运行完全正常，但是当我检查我的phpmyadmin时，没有更新任何行。我还尝试从同一个表中更新不同的列，但这些列也没有用。

任何人都可以帮助我吗？

（我试图在另一个表中更新一行，但似乎工作正常。）

PHP：

    <?php
    require '../app/db.php';
    require '../app/init.php';
    if (!isset($_SESSION['loggedin']) || !$_SESSION['loggedin']) {
        header('Location: '.ADMIN_URL);
        exit;
    }
    //Get all orders
    $sth = $db->prepare("SELECT id, invoice_id, order_id, order_completed_at, total_shipping, shipping_tax, owner_site_name, export_csv FROM orders WHERE id > 1573");
    $sth->execute();
    $results = $sth->fetchAll(PDO::FETCH_ASSOC);
    $results = json_decode(json_encode($results), 1);
    foreach ($results as $order => $value) {
        $csv = json_decode($value['export_csv'], 1);
        $total_shipping = number_format($value['total_shipping']+$value['shipping_tax'], 2, ',', '.');
        $date = date("d-m-Y", strtotime(explode(' ', $value['order_completed_at'])[0]));
        $shipping = $date.';-'.$value['invoice_id'].';0;"1050";"";"'.$value['owner_site_name'].' (ID: '.$value['order_id'].')";'.$total_shipping.';"DKK";100,00;"Salg";"";0;'.$date.';0,00;;"";"";0,00;0;"";0;"";"";"";"";"";0;0,00;"";"";"";"";"";0';
        $csv['separated']['shipping'] = $shipping."\n";
        $joins = explode("\n", $csv['joined']);
        foreach ($joins as $join => $value) {
            $explode = explode(';', $value);
            if (isset($explode[3])) {
                if ($explode[3] == '"1040"') {
                    $joins[$join] = $shipping;
                }
            }
        }
        $csv['joined'] = implode("\n", $joins);
        $csv = json_encode($csv);
        //Update export_csv
        $sth = $db->prepare("UPDATE `orders` SET `export_csv` = :csv WHERE `id` = :id");
        $sth->bindParam(':csv', $csv);
        $sth->bindParam(':id', $value['id']);
        $res = $sth->execute();
        if (!$res) {
            echo 'Failed for order #'.$value['id'].'<br>';
        }
    }
    ?>

（也许某种＆＃34;强制更新＆＃34;，因为我怀疑我的UNIQUE键是否会使行无法更新）？

解决方案：

进一步调试后，我发现$value['id']为NULL。

我无法解释原因，但我使用$results[$order]['id']来获取行的ID。

PDO PHP - 更新行无效 - 无错误
