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'] = $_POST['columnId'];
            echo "<h3>";
            echo "Please enter the name for each seat:<br><p>&nbsp</p>";
            echo "";
            foreach($_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。

我认为你不应该在这部分使用 jquery。尝试使用带有 html 表单的 php(在具有复选框的座位旁边显示一个输入)然后将数据保存到 mysql 座位 ID、座位用户 ID、座位名称等......然后只需提取数据并做任何你想做的事情。
