wireRenderFile not returning string output

[abdus]

Hi,

I'm working on a custom contact form and I want to create an HTML markup for email body. After tedious and long searches I've found wireRenderFile function that does exactly what I need. Pass in template file and variables to use, it returns the output. Except that it doesn't. It simply returns an empty string.

I tested the same template using wireIncludeFile, it echoes the output perfectly.

(I'm using the latest 2.6.16 DEV version of ProcessWire)

Here's what I did:

1. Got and processed user inputs
2. Created a simple partial template file at templates/partials/_email.php with contents
   

   <?php if (isset($vars)): ?>
   <div class="meta">
       From: <b><?= $vars["name"] ?></b><br>
       Email: <?= $vars["email"] ?><br>
       sent this at <?= $vars["date"] ?>
   </div>
   <hr>
   <div class="message">
       <?= $vars["body"] ?>
   </div>
   <?php endif; ?>
   

3. Prepare mail data and send it

   $mail = wireMail();
   ...
   ...
   $bodyHTML = wireRenderFile("partials/_email.php", array(
           "name" => $name,
           "body" => $body,
           "email" => $email,
           "date" => date("r"),
       ));
   ...
   ...
   ...
   if ($mail->testConnection()) {
       $mail->sendSingle(true)
           ...
           ->bodyHTML($bodyHTML)
           ->send();
   }
   

The $bodyHTML variable gets an empty string from wireRenderFile function. When I replace it with wireIncludeFile

$bodyHTML = wireIncludeFile("partials/_email.php", array(<data>));

The template is rendered correctly, but echoed instead of returned (it returns boolean anyway). I think I can collect the output using ob_start() and ob_get_contents(), but the code above should work correctly and I dont want to use a hack for it, yet.

Thanks in advance for any help.

EDIT:

I solved it.

wireRenderFile function imports given data in $vars variable as separate entities as in 

// Second argument is $vars
$bodyHTML = wireRenderFile("partials/_email.php", array(
        "name" => $name,
        "body" => $body,
        "email" => $email,
        "date" => date("r"),
    ));

// $vars variable is included in template file as in
$name = $vars["name"]
...
// etc.

There's no need (can't) to access to $vars variable. I was able to output the data with this modified template file. Notice the if (isset($vars)) is removed since $vars variable doesnt exist in that context.

<div class="meta">
    From: <b><?= $name ?></b><br>
    Email: <?= $email ?><br>
    sent this at <?= $date ?>
</div>
<hr>
<div class="message">
    <?= $body ?>
</div>
