关于您的评论的更新...
据我了解,some result
您的意思是从数据库生成的数据。在这种情况下,您可以尝试这样的事情:
function example_block_content() {
// Query for active users from database
$users = db_select('users', 'u')
->fields('u', array('uid', 'name'))
->condition('u.status', 1)
->execute()
->fetchAll();
$output = '';
foreach ($users as $user) {
$output.= '<div>'. $user->name .'</div>';
}
$output = "<div>Hello World". $output ."</div>";
return $output;
}
这将为您提供以下输出:
<div>Hello World
<div>admin</div>
<div>ndrizza</div>
<div>Vlad Stratulat</div>
...
</div>
或者您可以尝试:
function custom_logo_module_block_view($delta = '') {
$block = array();
if ($delta == 'example') {
$block = array(
'subject' => t('Active users list'),
// this will return "Hello World + some result" text inside <div>
'content' => "<div>Hello World + some result</div>"
);
}
return $block;
}
这两种方法都有效,但它们不是正确的方法。生成内容的正确方法是我的第一个答案。阅读有关 Drupal 主题的更多信息。
