drupal - 将数据库中的数据打印到特定的块内容

Question

我需要将简单数据从数据库打印到特定块，我使用了下面给出的代码并输出了文本，但它不在指定的块中（hello_world）。

function hello_world_block_view($delta = '') {
  $block = array();

  if ($delta == 'hello_world') {
 $sql = "SELECT Test_name FROM Test_table";
        $result = db_query($sql);
        $record = $result->fetch(); 
        foreach ($record as $records) {
             echo $records;
        }

    $block['subject'] = t('Hello world Subject');
    $block['content'] = t('Need to print database content');
  }

  return $block;
}

Answer 1

您需要将变量$records与$block['content']. 所以它看起来像：

function hello_world_block_view($delta = '') {
  $block = array();

  if ($delta == 'hello_world') {
    $output = '';
    $sql = "SELECT Test_name FROM Test_table";
    $result = db_query($sql);
    $record = $result->fetch(); 
    foreach ($record as $records) {
      $output .= $records;
    }

    $block['subject'] = t('Hello world Subject');
    $block['content'] = $output;
  }

  return $block;
}
