PHP mailer与SQL一起在特定行上发送电子邮件

我不使用日常的php、html、css，但我知道这种编程语言的基础知识。 我想通过按钮在指定行上发送电子邮件。（我附上了一张带有脚本索引页的图片，并用红色按钮标记）

目前，无论我按哪个按钮，代码都会向所有行发送电子邮件。 有人能告诉我怎么才能只从指定行的按钮发送电子邮件吗

我的代码是：

<?php
require "config.php";
require "common.php";

try {
  $connection = new PDO($dsn, $username, $password, $options);

  $sql = "SELECT * FROM tasks";

  $statement = $connection->prepare($sql);
  $statement->execute();

  $result = $statement->fetchAll();
} catch(PDOException $error) {
  echo $sql . "<br>" . $error->getMessage();
}

if (isset($_GET['id'])) {
  try {
    $connection = new PDO($dsn, $username, $password, $options);
    $id = $_GET['id'];

    $sql = "INSERT INTO oldtasks SELECT * FROM tasks WHERE id = :id; DELETE FROM tasks WHERE id = :id;";
    $statement = $connection->prepare($sql);
    $statement->bindValue(':id', $id);
    $statement->execute();
    
    $task = $statement->fetch(PDO::FETCH_ASSOC);
  } catch(PDOException $error) {
  }
}
?>
<?php 
if(isset($_POST['button_pressed']))
{
    foreach ($result as $row) :
    $responsabil = $row['responsabil'];
    $produs = $row['produs'];
    $prob_recl = $row['prob_recl'];
    $cauza = $row['cauza'];
    $act_impl = $row['act_impl'];
    $termen = $row['termen'];
    
    $from = "tasks@plastec-romania.ro";
    $headers = "From:" . $from;
    $to      = $responsabil;
    $subject = 'Reminder - '  .$produs ;
    
    $message = "Reminder: \n\nProdus: " . $produs . "\nProblema reclamata: " . $prob_recl . "\nCauza: " . $cauza . "\nActiuni de implementat: " . $act_impl . "\nTermen: " . $termen . "\n\nTasks: http://192.168.0.8/tasks";   
    
    mail($to, $subject, $message, $headers);
    endforeach;
}
?>

请去读一读。与您的问题相关的最小代码，以文本形式直接属于您的问题，并且格式正确。不要只是将其转储到外部平台上。首先，您需要使用按钮传递特定的行id。然后，您需要从数据库中仅选择具有该ID的记录作为开始，或者如果出于某种原因仍要循环所有记录，则在循环中，仅当当前记录的ID与您通过表单提交的ID匹配时，才发送邮件。您能举个例子吗？我知道在这一行“foreach（$result as$row）：”添加数据库中的ID行，对吗？可能类似于
，ID值将用于“if”或“foreach”？很高兴现在解决了这个问题。不过，请注意一下catch（PDOException$e）{echo$e->getMessage（）；}
的逻辑……如果查询失败，您将输出异常消息（在实时系统中，异常消息本身并不十分安全，应该记录），但是，即使出现严重故障，您的代码只是在下面继续，并尝试创建电子邮件。但很明显，它会失败，因为$row不会被定义，所以它还会产生其他错误和警告。这不是一种处理数据库错误的可靠方法。我也不知道您为什么再次创建
$connection
？它已经在脚本的第一部分中创建。您不需要为每个查询建立单独的连接。谢谢。此代码仅在本地公司LAN中的有限连接中使用。我现在已经创建了脚本，可以使用后，没有人会更改它：）
此代码用于有限的连接，仅在本地公司局域网中使用
抱歉，我不确定您为什么认为这与我所说的任何内容有关？你能解释一下吗？编写安全可靠的代码不仅限于面向internet的应用程序。每个应用程序都应该这样写。你不能假设你的局域网内的用户和设备永远不会构成威胁。它不会通过公共IP访问。仅在具有内部IP的LAN上工作。
