使用ob_start

  ob_start（）; 
包含'htmlemail.php'; 
 $ body = ob_get_clean（）; 
 

或者

例如

您的html模板中有这样的变量：
$ b

感谢{NAME}与我们联系。

您的电话号码是{PHONE}

然后在调用phpmailer之前，创建一个数组来处理电子邮件正文：

pre $ $ $ $ $ $ $ $ $ $ $ $ $ $ $'$' $ b'phone'=> $ _POST ['phone']，
）;

最后，用phpmailer ...

  $ body = file_get_contents（'htmlemail.phtml'）; 

 if（isset（$ email_vars））{
 foreach（$ email_vars as $ k => $ v）{
 $ body = str_replace（'{'。strtoupper（ $ k）。'}'，$ v，$ body）; 


 code 


 $ b这样你的电子邮件就会拥有你所有的动态内容需要在身体里。 
I'm trying to get the emails sent from my contact (using PHPMailer) sent in a nice html template (phtml actually).

What works: I receive the html template so no issue with the transmission

What does not work: The variables (message, phone number, etc) are not reflected in the body of my html template.
I have tried several things in the html template, without success: <?= htmlspecialchars($message) ?> and #message# and <?php echo$_POST['message'] ?>

What is the issue?

Thanks,

Here is the PHPMailer code:
<?php

require 'PHPMailer/PHPMailerAutoload.php';

$mail = new PHPMailer;
$mail->CharSet = 'utf-8';
$body = file_get_contents('htmlemail.phtml');

//Enable SMTP debugging. 
$mail->SMTPDebug = false;                               
//Set PHPMailer to use SMTP.
$mail->isSMTP();            
//Set SMTP host name                          
$mail->Host = "smtp.sendgrid.net";
//Set this to true if SMTP host requires authentication to send email
$mail->SMTPAuth = true;                          
//Provide username and password     
$mail->Username = "";                 
$mail->Password = "";                           
//If SMTP requires TLS encryption then set it
$mail->SMTPSecure = "tls";                           
//Set TCP port to connect to 
$mail->Port = 587;                                   

$mail->From = $_POST['email'];
$mail->FromName = $_POST['first_name'] . " " . $_POST['last_name'];

$mail->addAddress("@gmail.com");
//CC and BCC
$mail->addCC("");
$mail->addBCC("");

$mail->isHTML(true);

$mail->Subject = "Nouveau message depuis ";

$mail->MsgHTML($body);



$response = array();
if(!$mail->send()) {
  $response = array('message'=>"Mailer Error: " . $mail->ErrorInfo, 'status'=> 0);
} else {
  $response = array('message'=>"Message has been sent successfully", 'status'=> 1);
}

/* send content type header */
header('Content-Type: application/json');

/* send response as json */
echo json_encode($response);

?>




Using ob_start
ob_start();
include 'htmlemail.php';
$body = ob_get_clean();

Or

You can also use a templating method to generate the email body for multiple uses.

E.g.

In your html template, have variables assigned like this:

  
Thank you {NAME} for contacting us.
  
  
Your phone number is {PHONE}

Then before calling your phpmailer, create an array to process the email body:
$email_vars = array(
    'name' => $_POST['name'],
    'phone' => $_POST['phone'],
);

And finally, with phpmailer...
$body = file_get_contents('htmlemail.phtml');

if(isset($email_vars)){
    foreach($email_vars as $k=>$v){
        $body = str_replace('{'.strtoupper($k).'}', $v, $body);
    }
}

This way your emails will have all the dynamic content you need in the body.
