php - 插入查询后如何基于两个表发送电子邮件？

Question

我正在尝试从 candidates_table 向用户发送电子邮件更新，但电子邮件的内容来自 jobs_list 表。请在下面查看我的尝试，我正在使用 PHPmailer，并且没有收到任何错误。下面的脚本是表单的处理脚本。

正在显示 jobs_list 中的数据，但未显示 candidates_table 数据。

这就在插入语句的下面:

更新:

$vac_last_id = $dbh->lastInsertId();
echo $vac_last_id; 


$sql = $dbh->prepare("SELECT * FROM jobs_list WHERE id=:id");

$sql->bindValue(':id', $vac_last_id, PDO::PARAM_INT);

if($sql->execute()) {
   $sql->setFetchMode(PDO::FETCH_ASSOC);

}

while($row = $sql->fetch()) { 


$mail = new PHPMailer;
$mail->isSMTP();
$mail->Host = '';
$mail->SMTPAuth = true;
$mail->SMTPKeepAlive = true; // SMTP connection will not close after each email sent, reduces SMTP overhead
$mail->Port =;
$mail->Username = '';
$mail->Password = '';
$mail->setFrom('', '- Vacancies');
$mail->addReplyTo('', '- Vacancies');

$mail->Subject = "";
//Same body for all messages, so set this before the sending loop
//If you generate a different body for each recipient (e.g. you're using a templating system),
//set it inside the loop
$mail->Body = 'THE BODY...';

      //msgHTML also sets AltBody, but if you want a custom one, set it afterwards
      $mail->AltBody = 'To view the message, please use an HTML compatible email viewer';
      //Connect to the database and select the recipients from your mailing list that have not yet been sent to
      //You'll need to alter this to match your database

    $mysql = $dbh->prepare("SELECT * FROM candidates_table WHERE receive_email = 2");
    if ($mysql->execute()) {
      $mysql->setFetchMode(PDO::FETCH_ASSOC);

        }

foreach ($mysql as $row) { //This iterator syntax only works in PHP 5.4+

$mail->addAddress($row['email_address'], $row['full_name']);

if (!$mail->send()) {
    echo "Mailer Error (" . str_replace("@", "&#64;", $row["email_address"]) . ') ' . $mail->ErrorInfo . '<br />';
    break; //Abandon sending
} else {
    echo "Message sent to :" . $row['full_name'] . ' (' . str_replace("@", "&#64;", $row['email_address']) . ')<br />';
    //Mark it as sent in the DB
}
// Clear all addresses and attachments for next loop
$mail->clearAddresses();
 }   
}

在 job_listing 表中插入工作列表。查找当前 job_listing 表 ID。再次获取并找到所有候选人发送电子邮件。

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {

  require 'PHPMailer/PHPMailerAutoload.php';
  include 'db_connect.php';

  $contact_name  = $_POST['contact_name'];

  $latest_job_id = 0;

  $stmt = $dbh->prepare("INSERT INTO jobs_list (jobTitle, company_name, job_details, salary_info, salary_extra, apply_link, company_email, company_phone, TimeStamp) VALUES (:jobTitle, :company_name, :job_details, :salary_info, :salary_extra, :apply_link, :company_email, :company_phone, NOW())");
  $stmt->bindParam(':jobTitle', $_POST['jobTitle'], PDO::PARAM_STR);
