如何將表單詳細信息發送到數據庫以及如何發送包含表單詳細信息的電子郵件CodeIgniter

Question

這是提交表單后的代碼。 我已經成功地將值顯示在頁面上，但是隨后我希望將這些相同的值插入數據庫中，同時將它們作為電子郵件發送給用戶和管理員電子郵件。 用戶電子郵件（如果是$_POST值形式的一部分）。 我想稍后提取和更新值。 那不是問題。 問題是要同時或一次又一次地保存到數據庫，電子郵件客戶端和admin並保存到數據庫。

注意：我正在使用API​​直接在顯示之前轉換那里的一些值，因此在控制器或模型中進行操作可能會保存原始值，而不是不需要的轉換后的值。 除非有更好的方法可以做到這一點。 我正在使用CodeIgniter 3。

請幫幫我。 謝謝。 下面的代碼：

<?php
    function generateRandomString($length = 26) {
        $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
        $charactersLength = strlen($characters);
        $randomString = '';
        for ($i = 0; $i < $length; $i++) {
            $randomString .= $characters[rand(0, $charactersLength - 1)];
        }
        return $randomString; 
    }
?>

<?php
    $user_id = $_POST['user_id'];
    $email = $_POST['email'];
    $username = $_POST['username'];
    $txn_ref = strtoupper(generateRandomString());
    $txn_status = "Pending";
    $exc_from = $_POST['exc_from'];
    $exc_to = $_POST['exc_to'];
    $from_amount = $_POST['from_amount'];
    $to_amount = $_POST['to_amount'];
    $account = $_POST['account'];
?>

<div class="row">
<h3>Your <?php echo $exc_from ?> to <?php echo $exc_to ?> Transaction Details</h3>
<div class="table-responsive">
 <table class="table table-striped">
  <tbody>
    <tr>
      <th>Payment ID</th>
      <td><?php echo $txn_ref ?></td>
    </tr>
    <tr>
      <th>Email</th>
      <td><?php echo $email ?></td>
    </tr>
    <tr>
      <th>Username</th>
      <td><?php echo $username ?></td>
    </tr>
    <tr>
      <th>You Give</th>
      <td><?php echo $from_amount ?> <?php echo $exc_from ?></td>
    </tr>
    <tr>
      <th>You Get</th>
      <td><?php echo $to_amount ?> <?php echo $exc_to ?></td>
    </tr>
    <tr>
      <th>Your <?php echo $exc_to ?> Wallet</th>
      <td><?php echo $account ?></td>
    </tr>
    <tr>
      <th>Transaction Status</th>
      <td><?php echo $txn_status ?></td>
      <td></td>
    </tr>
    <tr>
      <th>Make Payment to</th>
      <td><?php echo $ouraccount; ?></td>
      <td></td>
    </tr>
    <tr>
      <th>View in Dashboard</th>
      <td><a href="<?=base_url()?>transaction/<?php echo $txn_ref ?>">View Transaction</a><br></td>
      <td></td>
    </tr>
  </tbody>
</table>

Answer 1

對於任何對我的問題的答案感興趣的人，我都花了點時間，找出了對我有用的方法。 也許可以幫到你。 我可以編輯，因為我不太確定我是否遵循最佳實踐，但是我遵循的大多數最佳實踐都沒有給出理想的結果。 一切按此順序放入同一文件。

<?php
function generateRandomString($length = 26) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$charactersLength = strlen($characters);
$randomString = '';
for ($i = 0; $i < $length; $i++) {
$randomString .= $characters[rand(0, $charactersLength - 1)];
}
return $randomString; }?>

<?php
$user_id = $_POST['user_id'];
$email = $_POST['email'];
$username = $_POST['username'];
$txn_ref = strtoupper(generateRandomString());
$txn_status = "Pending";
$exc_from = $_POST['exc_from'];
$exc_to = $_POST['exc_to'];
$from_amount = $_POST['from_amount'];
$to_amount = $_POST['to_amount'];
$account = $_POST['account'];

?>

在頁面上顯示

 <!-- Display Values -->
   <div class="row">
    <h3>Your <?php echo $exc_from ?> to <?php echo $exc_to ?> Details</h3>
    <div class="table-responsive">
   <table class="table table-striped">
    <tbody>
      <tr>
        <th>Payment ID</th>
      <td><?php echo $txn_ref ?></td>
      </tr>
      ...
         <th>View in Dashboard</th>
      <td><a href="<?=base_url()?>transaction/<?php echo $txn_ref ?>">View 
  Transaction</a><br></td>
       <td></td>
    </tr>
   </tbody>
  </table>
  </div>
  </div>

插入數據庫

    <?php
  //Insert into Database

 $params = array(
'user_id' => $user_id ,
'email' => $email ,
'username' => $username ,
'txn_ref' => $txn_ref ,
'txn_status' => $txn_status ,
'exc_to' => $exc_to ,
'exc_from' => $exc_from ,
'from_amount' => $from_amount ,
'to_amount' => $to_amount ,
'account' => $account ,
);

$this->db->insert('transactions',$params);
return $this->db->insert_id();
?>

發電子郵件

<?php
 //Send as Email
$m_user_id = $user_id;
$m_email = $email;
$m_username = $username;
$m_txn_ref = $txn_ref;
$m_exc_to = $exc_to;
$m_exc_from = $exc_from;
$m_from_amount = $from_amount;
$m_to_amount = $to_amount;
$m_account = $account;
$message = 'Message Here';

 $this->load->library('email');
 config['mailtype'] = 'html';

 $this->email->from('from@email.com', 'From');
 $this->email->to($m_email);
 $this->email->cc('cc@email.com');

 $this->email->subject('Email Test');
 $this->email->message($message);

 $this->email->send();
 if ($this->email->send(FALSE))
 {
    echo 'Mail was not sent';
 }

 ?>

我希望這有幫助
