为什么我的邮件正文没有以 drupal_mail() 格式发送？

Question

我是非常新的drupal表单，但已经设法设置了一个drupal_mail函数，该函数在提交时将电子邮件发送到所需的位置，其中包含正确的$subject消息和$from电子邮件地址。但是，它不会发送消息的正文。我已经用谷歌搜索/尝试了很多东西，但似乎没有什么能抓住正确的值。有人能明白为什么吗？提前感谢您的帮助。

function drupalform_menu() {
$items['drupalform/form1'] = array(
    'type' => MENU_CALLBACK,
    'access arguments' => array('access content'),
    'page callback' => 'drupal_get_form',
    'page arguments'=>array('drupalform_form1'));
  return $items;
} ?>

<?php function drupalform_form1() {
$form = array(
    '#prefix' => '<div id="contact-form" class="row section"><div 
class="container">',
    '#suffix' => '</div></div>',
); ?>

   <?php $form['name']=array(
    '#prefix' => '<div class="col l5 s12">',
    '#type'=>'textfield',
    '#title'=>t('FIRST & LAST NAME'),
  ); ?>
<?php $form['email']=array(
    '#suffix' => '</div>',
    '#type'=>'textfield',
    '#title'=>t('EMAIL'),
  ); ?>
 <?php $form['message']=array(
    '#prefix' => '<div id="form-message" class="col l5 push-l1 s12 ">',
    '#type'=>'textarea',
    '#title'=>t('MESSAGE'),
  ); ?>
<?php $form['submit']=array(
    '#suffix' => '</div>',
    '#type'=>'submit',
    '#value'=>t('SEND MESSAGE')
  );
  return $form; ?>

<?php } ?>

<?php
function drupalform_form1_submit($form, $form_state) {
$to = "[e-mail]";
$from = "[e-mail]";
$subject = "New message from the Louisville Digital Inclusion Site";
$body = $form_state['values']['message'];

$params = array(
    'subject' => $subject,
    'body' => $body,
    );
drupal_mail('test', 'information', $to, language_default(), $params, $from);
drupal_set_message("Form has been submitted");
}

function test_mail($key, &$message, $params) {
switch ($key) {
case 'information':
  $message['subject'] = $params['subject'];
  $message['body'] = $params['body'];
break;
}
}
?>

搞清楚了！我不得不将我的test_mail函数更改为如下：

function test_mail($key, &$message, $params) {
switch ($key) {
case 'information':
$message['subject'] = $params['subject'];
$message['body'][] = $params['body'];
break;
}
}

我需要在$message['body'][] = $params['body']后添加空括号.
