Question

我有一张表格供用户提交查询。提交表单后，数据将转到php文件，它将连接到数据库。现在，我有update.php的问题。技术上，当在admin.php中单击“kemaskini”按钮时，update.php将显示有关其ID的用户个人信息的完整详细信息。

但是这里发生了什么，代码显示如下，例如，当我点击Lily时，会显示Lily详细信息。但是当我点击Julia时，Lily会再次显示细节。它只生产百合细节：（

admin.php的

Answer 1

在admin.php中，您错过了结束“＆gt;”在INPUT标签中。

<input type='hidden' name='id' value=<?php echo $row['id']; ?>

应该是

<input type='hidden' name='id' value="<?php echo $row['id']; ?>">

所以隐藏的输入没有被关闭，不是由浏览器发送的，所以$ _POST ['id']是空的，这就是为什么你一直得到带有空id的相同记录的原因。

好的做法是始终使用“”作为值。有了它们，您将清楚地看到标签是否已关闭，您将避免使用带空格的值的问题。

如何显示有关$ id的完整详细信息？
