Question

我在HTML中有这个DB条目列表，我希望每行旁边都有一个编辑按钮，以便能够更新用户信息。 POST变量到达更新数据库行的.php文件，问题是我只能编辑列表的最后一行，好像它会自动通过POST提交数据。我只想在按下编辑按钮后才提交数据。

显示当前会员信息并点击重定向到执行查询本身的.php文件

<?php
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("users") or die(mysql_error());

$id = $_POST['id'];

$query = "SELECT * FROM userinfo WHERE id LIKE $id";

$result = mysql_query($query);

$row = mysql_fetch_array($result);

感谢您的帮助。

Answer 1

替换您的编辑按钮代码。

echo "<td><form action='info.php' method='POST'><input type='hidden' name='id' value='".$row['id']."'/><input type='submit' name='submit-btn' value='View/Update Details' /><form></td></tr>";

使用此代码

echo '<a href="update.php/'. $row["id"].'"';

Answer 2

替换

<form>

与

</form>

正确地结束表单，否则它将被视为只有一个表单，并且将使用最后一行的值，因为它们是重复的（一个表单包含所有字段）

PHP不需要的自动提交
