我在网页中显示的 mysql 记录表的末尾有一个编辑按钮。

但是，当我单击编辑按钮时，我的 edit.php 只会生成一个空白页面。

我不知道为什么：

<?php
// contact to database
$connect = mysql_connect("localhost", "xxx", "xxx") or die ("Error , check your server connection.");
mysql_select_db("xxx");
?>

<?php
$posted_id = $_POST['ID'];
?>

<div class="form">            
<?php 

$result = mysql_query("SELECT * FROM ff_projections WHERE ID = '$posted_id'") or die ("Error in query");
if ($row = mysql_fetch_array($result)) {

echo "<form method='post' action='update.php'>";
echo "<label for='Player'>Player Name:</label> <input type='text' name='Player' value='" . $row['Player'] . "' />";
echo "<label for='Pass_Yds'>Pass Yds:</label> <input class='short' type='text' name='Pass_Yds' value='" . $row['Pass_Yds'] . "' />";

echo "<label for='Rush_Yds'>Rush Yds:</label> <input class='short' type='text' name='Rush_Yds' value='" . $row['Rush_Yds'] . "' />";
echo "<label for='Rush_TDs'>Rush TDs:</label> <input class='short' type='text' name='Rush_TDs' value='" . $row['Rush_TDs'] . "' />";
echo "<input type='submit' name='submit' value='Update Player' />";
echo "<input type='hidden' name='ID' value='" . $row['ID'] . "' />";
echo "</form>";
}
?>
</div>


</body>
</html>

我将 ID 作为隐藏字段，因为我不希望它可见或可编辑。

这是使用edit.php的页面：

<?php
// contact to database
$connect = mysql_connect("localhost", "xxx", "xxx") or die ("Error , check your server connection.");
mysql_select_db("xxx");
?>

永远不要忘记正确清理任何触及数据库“mysql_real_escape_string();.

但它似乎在抱怨未定义的索引 $_POST['ID'];，这是因为要么没有任何东西被发送到它，要么可能有一个命名问题被发布到该页面。

尝试将您的值之一的静态变量设置为 $posted_id: $posted_id = 3262732 （或已知的帖子 ID）以查看您的表单是否正确返回。

如果这确实有效，那么查看哪些数据正在发布到 edit.php。
