如何在PHP mail()函数中包含对文件的调用 - How to include a call to a file in PHP mail() function

我有以下发送电子邮件的函数:

function send_email($email){
        $subject = "TITLE";
        $message = "HERE IS THE MESSAGE";
        // Always set content-type when sending HTML email
        $headers = "MIME-Version: 1.0" . "'r'n";
        $headers .= "Content-type:text/html;charset=UTF-8" . "'r'n";
        // More headers
        $headers .= 'From: <emaily>' . "'r'n";
        mail($email,$subject,$message,$headers);
    }

我想在保存模板的文件email.html中调用，而不是将$message作为字符串。

我添加了这个:

require 'email.html';

但是我如何调用文件呢?

$message = [call in email.html here]

Require用于在另一个php文件中调用函数，或者在HTTP响应中包含一些数据。

对于这个问题，file_get_contents('email.html')是首选。这就是我要使用的方法:

function send_email($email){
    $subject = "Subject of your email";
    $message = "";
    if(file_exists("email_template.html")){
        $message = file_get_contents('email_template.html');
        $parts_to_mod = array("part1", "part2");
        $replace_with = array($value1, $value2);
        for($i=0; $i<count($parts_to_mod); $i++){
            $message = str_replace($parts_to_mod[$i], $replace_with[$i], $message);
        }
    }else{
        $message = "Some Default Message"; 
        /* this likely won't ever be called, but it's good to have error handling */
    }
    // Always set content-type when sending HTML email
    $headers = "MIME-Version: 1.0" . "'r'n";
    $headers .= "Content-type:text/html;charset=UTF-8" . "'r'n";
    // More headers
    $headers .= 'From: <doNotReply@myDomain.com>' . "'r'n";
    $headers .= "To: <$email>'r'n";
    $header .= "Reply-To: doNotReply@myDomain.com'r'n";
    mail($email,$subject,$message,$headers);
}

我稍微修改了你的代码，并添加了file_get_contents和file_exists。file_exists确认文件在那里。如果不是，则可以避免尝试读入时的潜在错误，并且可以将其更改为使用默认值。下一个添加的是for循环。在"$parts_to_mod"数组中，输入待替换模板的默认值。在$replace_with数组中，放入您想要替换模板部分的唯一值。

作为我使用这个的一个例子，我有一个模板URL，我的一个程序说id=IDENTIFIER&hash=THEHASH，所以在我的程序中，我的parts_to_mod说$parts_to_mod = array("IDENTIFIER", "THEHASH");，我的replace_with说$replace_with = array($theUsersIdentifier, $theUsersHash);。然后它进入for循环并用replace_with中的值替换parts_to_modify中的值。

简单的概念，它们使你的代码更短，更容易维护。

编辑:

下面是一些示例代码:

假设模板是:

<span>Dear PUTNAMEHERE,</span><br>
<div>PUTMESSAGEHERE</div>
<div>Sincerely,<br>PUTSENDERHERE</div>

在php代码中，我们写入:

$parts_to_mod = array("PUTNAMEHERE", "PUTMESSAGEHERE", "PUTSENDERHERE");
$replace_with = array($name, $theBodyOfYourEmail,  $whoYouAre);

just use file_get_contents('email.html')这个方法返回一个包含文件内容的字符串

您可以使用此函数调用自定义电子邮件模板。

function email($fields = array(),$name_file, $from, $to) {         
  if(!empty($name_file)) {             
    $mail_tem_path = 'templates/mails/mail--'.$name_file.'.php'; //change path of files and type file.
    if(file_exists($mail_tem_path)) {
      $headers = "MIME-Version: 1.0". "'r'n";
      $headers .= "Content-Type: text/html;charset=UTF-8". "'r'n";
      // Additional headers
      $headers .= "From:".$fields["subject_from"]." <$from>". "'r'n";  
      $headers .= "Content-Transfer-Encoding: 8Bit". "'r'n";
      $message = file_get_contents($mail_tem_path);
      $message = preg_replace("/'"/", "'", $message);
      foreach ($fields as $field) {
       // Replace the % with the actual information  
       $message = str_replace('%'.$field["name"].'%', $field["value"], $message);
      }
      $send = mail($to, $fields["subject"], $message, $headers);
    } else {
      $send = mail($to, "Error read mail template", "Contact with admin to repair this action.");
    }
  } else {
    $send = mail($to, "Error no exist mail template", "Contact with admin to repair this action.");
  }
  return $send;  
}

模板的html

<html>
 <body>
  <a href="/home">TODO write content %value_on_array%</a>
 </body>
</html>

数组和执行函数

 $fields = array(
  "subject" => "tienda_seller_subject",
  "subject_from" => "tienda_email_subject_from",
  0 => array(
    "name" => "value_on_array",
    "value" => "result before change"
  ),                  
 );
 //email($fields = array(),$name_file, $from, $to);
 email($fields, 'admin', 'owner@email.com', 'client@email.com');

结果
