使用 PDO/MySQL 发送电子邮件并将自动递增编号附加到电子邮件

Question

你好我最喜欢的人！

我正在尝试在提交表格后发送一封电子邮件，电子邮件中附有 AUTO INCREMENT 编号，因为 AUTO INCREMENT 编号是客户的工作卡参考编号。到目前为止，我已经成功地创建了插入脚本，它可以将数据完美地插入到数据库中，还可以发送电子邮件。但不会将 AUTO INCREMENT 编号附加到电子邮件中。在我的 MySQL 数据库中，INT(11) AUTO INCREMENT 主键是“job_number”。

这是我的插入页面：

<form action="addnewrepairprocess.php" method="POST">
         
         <div class="form-group">
      <label for="date">Date</label>

我试着按照这个啧啧：Send email with PHP from html form on submit with the same script

我也尝试激活此页面上的错误但没有结果：

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

我是新手，从来没有做过像这样需要在电子邮件中发送 AUTO INCREMENT 号码的代码。请有人帮助我。如果需要更多说明，我可以编辑我的问题。

编辑：我做了一些研究，发现我可以使用 lastInsertID（https://dev.mysql.com/doc/refman/8.0/en/information-functions.html#function_last-insert-id 函数。一些帮助实现这一点将不胜感激。

Answer 1

 $insertId = false;
 if($insert_stmt->execute())
    {
     $insertId = $insert_stmt->insert_id;      
     $insertMsg="Created Successfully........sending email now"; 

     
    }

if($insertId){

   // do stuff with the insert id
}

Answer 2

好的，所以我使用 MAX 方法解决了这个问题。我在 createnewrepairs.php 页面的顶部添加了以下内容：

$stmt = $db->prepare("SELECT MAX(job_number) AS max_id FROM repairs"); $stmt -> execute(); $job_number = $stmt -> fetch(PDO::FETCH_ASSOC); $max_id = $job_number['max_id'];

然后在同一页面上，我添加了以下表单字段

<div class="form-group">
  <label for="job_number">Job Number</label>
  <input type="job_number" name="job_number" id="job_number" class="form-control" value="<?php echo $max_id+1;?>" readonly>
</div>

然后在表单处理页面 (processnewrepair.php) 我原来的代码 post 工作并生成了 AUTO INCREMENT NUMBER 以在电子邮件中发送。
