Question

我在显示的mysql记录表的末尾有一个编辑按钮在网页上。

但是，当我单击编辑按钮时，我的edit.php只会生成一个空白页。

我无法弄清楚原因：

<?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'];
?>

<body>

<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='Pass_TDs'>Pass TDs:</label> <input class='short' type='text' name='Pass_TDs' value='" . $row['Pass_TDs'] . "' />";
echo "<label for='Int_Thrown'>Int Thrown:</label> <input class='short' type='text' name='Int_Thrown' value='" . $row['Int_Thrown'] . "' />";
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。

以下是使用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");
?>

Answer 1

永远不要忘记正确清理触及数据库的任何条目“mysql_real_escape_string（）;.

但它似乎是抱怨未定义的索引$ _POST ['ID'];，因为要么没有发送任何内容，要么就是有一个命名问题被发布到该页面。

尝试将其中一个值的静态变量设置为$ 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。

如果确实有效，那么请查看要发布到edit.php。

的数据

为什么我的PHP代码编辑我的mySQL表显示为空白页？
