Question

In the submitForm of some form of my custom module, an email is sent this way: 

$sTo = 'eric.falzon@free.fr';
$sBcc = _setListOfRecipients();
$aParams = array($sBcc, $rpYear);
\Drupal::service('plugin.manager.mail')->mail('association', 'renewmembershipfirst', $sTo, 'fr', $aParams);

In my custom module, there is 

function association_mail($key, &$message, $aParams)
{
    $sFrom = \Drupal::config('system.site')->get('mail');
    $message['from'] = $sFrom;
    $message['headers'] = array(
        'Content-Type' => 'text/html',
        'bcc' => $aParams[0],
        'From' => $sFrom,
        'Sender' => $sFrom,
        'Return-Path' => $sFrom,
    );
    switch ($key) {
        case 'renewmembershipfirst':
            $message['subject'] = '[le Jardin de Poissy] Renouvellement d\'adhésion';
            $sBody = "<b>" . $aParams[1] . "</b>";
            $message['body'][] = check_markup(nl2br($sBody), 'full_html');
            break;
    }
}

The settings of mailsystem are these:

And in my theme templates folder (mysite/web/themes/contrib/mayo/templates/), there is my email template swiftmailer--association--renewmembershipfirst.html.twig: 

<html>
<head>
    <link href="https://fonts.googleapis.com/css?family=Montserrat" rel="stylesheet">
    <style type="text/css"> body {
            font-family: 'Montserrat', sans-serif;
            font-size: 14px;
        }
    </style>
</head>
<body>
<div>
    <table width="800px" cellpadding="0" cellspacing="0">
        <tr>
            <td>
                <div style="padding: 0px 0px 0px 0px;">
                    <p>
                        Chers adh&eacute;rents du <strong>Jardin de Poissy</strong>,<br>
                        <br>
                        La p&eacute;riode de renouvellement des adh&eacute;sions pour {{ body }} est ouverte !<br>
                        <br>
                        Pour nous signaler votre décision :
                    <ul>
                        <li>vous suivez ce <a href="{{ url('association.renew_membership') }}">{{ 'lien'|t }}</a>,</li>
                        <li>vous indiquez votre choix (Non, Oui),</li>
                        <li>vous soumettez.</li>
                    </ul>
                    En cas de réponse positive, la soumission déclenche le téléchargement de votre bulletin
                    d'adhésion.<br>
                    Vous l'imprimez et vous nous l'envoyez accompagné de votre règlement.<br>
                    <br>
                    Merci d'avance,<br>
                    <strong>Le Jardin de Poissy</strong><br><br>
                    P.-S. Ce courriel a été envoyé automatiquement. Merci de ne pas y répondre.
                    </p>
                </div>
            </td>
        </tr>
    </table>
</div>
</body>
</html>

The email is sent (and received). Everything is OK (From, To, Bcc, Subject, Body).
But (there is a but), I get this notice message 

Notice: Undefined index: filter_format in Drupal\swiftmailer\Plugin\Mail\SwiftMailer->massageMessageBody() (line 630 of modules/contrib/swiftmailer/src/Plugin/Mail/SwiftMailer.php).

Any idea what I am doing wrong?

Was it helpful?

Solution

I digged a litte bit in /swiftmailer/src/Plugin/Mail/SwiftMailer.php: 

public function massageMessageBody(array $message) {
    // Get default mail line endings and merge all lines in the e-mail body
    // separated by the mail line endings. Keep Markup objects and escape others
    // and then treat the result as safe markup.
    $line_endings = Settings::get('mail_line_endings', PHP_EOL);
    $applicable_format = $this->getApplicableFormat($message);
    $filter_format = $this->config['message']['filter_format'];
    $message['body'] = Markup::create(implode($line_endings, array_map(function ($body) use ($applicable_format, $filter_format) {

I went to $this->config['message'] with Devel' config editor: 

format: text/html
respect_format: true
convert_mode: true
character_set: UTF-8

which stands probably for
enter image description here But no trace of 'filter_format'.
Comparing with another D8 site I have with similar configuration, I found that what was missing is this entry in swiftmailer config: filter_format: plain_text.
I added it with Devel and now everything is OK: no more Notice: Undefined index: filter_format in Drupal\swiftmailer\Plugin\Mail\SwiftMailer.

But i have no clue of where this setting can be done thru UI.
Any idea?
