带有 SQL 的 PHP 邮件程序在特定行上发送电子邮件

Question

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。 （我附上了我的脚本索引页的图片，并用红色标记了按钮）

index page

目前，无论我按下哪个按钮，代码都会向所有行发送电子邮件。 有人可以解释一下如何仅在指定行上从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;
}

我解决了这个问题。 如果有人需要，下面是代码。

<?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'])) 
{
    try {
        $connection = new PDO($dsn, $username, $password, $options);
        $id = $_POST['button_pressed'];

        $sql = "SELECT * FROM tasks WHERE id = :id;";
        $statement = $connection->prepare($sql);
        $statement->bindValue(':id', $id);
        $statement->execute();
        
        $row = $statement->fetch(PDO::FETCH_ASSOC); 
    } catch (PDOException $e) {
        echo $e->getMessage();
    }
    
    $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";
