所以，我做了一个座位预订系统，每个座位都有复选框，用户选择这个框，座位被认为是保留的。
但现在我想让用户能够为每个标记的座位命名。我怎样才能做到这一点？

编辑：
我尝试了以下操作：当用户提交复选框时，这包括：
名称.php
<?php
//$mysql->commit();
session_start();
$_SESSION['rowId'] = $_POST['rowId'];
$_SESSION['columnId'] = $_POST['columnId'];
echo "<h3>";
echo "Please enter the name for each seat:<br><p> </p>";
echo "";
foreach($_POST['seats'] AS $seat) {
$rowId = substr($seat, 0, 1);
$columnId = substr($seat, 1);
echo $rowId . $columnId . '</br><form method="post" name="input" action="pt2.php" >
<input name="name" type="text"/></br>';
}
?>
<input type="submit" name="Submit" value="insert" />
</form>
pt2.php：
<?php
// Connect to MySQL
mysql_connect("localhost", "root", "root") or die("Connection Failed");
mysql_select_db("tickets")or die("Connection Failed");
$name = $_POST['name'];
session_start();
$rowId = $_SESSION['rowId'];
$columnId = $_SESSION['columnId'];
$result = mysql_query("UPDATE seats SET updatedby='".$name."' WHERE rowId='".$rowId."' AND columnId='".$columnId."'")
or die(mysql_error());
?>
如果用户只选择一个座位，此代码就像一个魅力。但是当有两个或更多时，$columnId 和 $rowId 不会发生应有的变化，只有最后一个检查座位的名称会发生变化。
