Question

我在代码的一行收到一个未定义的索引错误。我已经仔细检查了拼写并验证了它在我的数据库中的正确识别。我甚至换掉了另一段没有生成错误的代码，并将变量更改为无效。有问题的变量是FinalReviewDate。

    <h2>Project Updates</h2>
    <p class="first"></p>
    <form action="http://www.oldgamer60.com/Project/Update.php" method="post">

忘记关闭名称属性

<input type="text" name="FinalReviewDate" value="<?php if(isset($FinalReviewDate)){ echo $FinalReviewDate; } ?>">
                                        ^
