Question

我有一个复选框表格，该表格已发送到mail.php进行邮寄。所选项目应通过邮件发送。我有一个查询以输出选定的项目。在邮件正文中；为了回显从数据库中拉出的所有选定项，我需要将while循环等于一个变量。但是我无法做到平等。

<div class="crypt-mobile-menu">
            <ul class="crypt-heading-menu" role="menu">
                <li role="presentation"><a role="menuitem" href="/">Exchange</a></li>
                <li role="presentation"><a role="menuitem" href="OrderBook">Orders</a></li>
                <li role="presentation"><a role="menuitem" href="TradeBook">TradeBook</a></li>
                <li role="presentation"><a role="menuitem" href="Transactions">Transactions</a></li>
                <li role="presentation"><a role="menuitem" href="Balance">Balance</a></li>
                <li role="presentation"><asp:HyperLink role="menuitem" ID="menuUnlockMobile" runat="server" NavigateUrl="~/UnlockWallet">Unlock Wallet</asp:HyperLink></li>
                <li role="presentation"><a role="menuitem" href="https://urlzs.com/FyPs1" target="_blank">Submit Token</a></li>
                <li role="presentation"><a role="menuitem" href="https://docs.google.com/forms/d/1puQjsJLjQ25JZn8rcj" target="_blank">Airdrop</a></li>
                <li role="presentation"><a role="menuitem" href="https://medium.com/" target="_blank">Blog</a></li>
                <li role="presentation"><a role="menuitem" href="AboutUs">About Us</a></li>
            </ul>

        </div>

Answer 1

连接到字符串而不是打印输出。

$city_names = "";
while ($statement = $query->fetch(PDO::FETCH_ASSOC) {
    $city_names .= "<td>{$statement["city_name"]}</td>\n";
}

然后，您可以在电子邮件中使用$city_names。

Answer 2

$citiesName = [];

while ($statement = $query->fetch(PDO::FETCH_ASSOC)) { ?>
    <td><?php echo $statement["city_name"]?></td>
    <?php $citiesName[] = $statement["city_name"]?>
<?php }

//code ...
$mail->Body = "Selected cities: " . implode(',', $citiesName);

通过phpmailer发送变量之前，等于变量的循环
