Question

我将PHP验证和PHPmailer结合在一起，代码运行正常。我现在面临的唯一问题是，每当我单击“提交”时，“ textarea”消息将为空，因此我必须再次输入整个消息。例如：如果输入了错误的名称，并且所有其他字段都正确，则当您单击“提交”时，它将在名称字段下显示警告消息，但是该消息将为空，我希望我已经以正确的方式发送了我的消息。 *我使用的是没有作曲家的PHPmailer。

Answer 1

与input不同，textarea标签没有value属性，其文本直接写在开始和结束标签之间：

<textarea class="form-control" placeholder="Type your message here" type="text" name="message" tabindex="5"><?= $message ?></textarea>

Answer 2

您需要使用echo在文本区域中显示值。
然后，请勿使用value=" "，而应在textarea标签之间使用textarea的值

单击提交时，消息字段变为空
