我如何在这行 php 中创建一个 span 元素

Question

我应该为 $term['nodes'] 放置一个 span 元素 我试图放在括号之后和之间，但对我没有任何作用

if (isset($term['nodes'])) { $term['name'] = $term['name'] . ' (' . $term['nodes'] . ')'; }

这里是所有功能

    function bootstrap_taxonomy_menu_block($variables) {
  $tree = $variables['items'];
  $config = $variables['config'];

  $num_items = count($tree);
  $i = 0;

  $output = '<ul class="nav nav-pills nav-stacked">';
  foreach ($tree as $tid => $term) {
    $i++;
    // Add classes.
    $attributes = array();
    if ($i == 1) {
      $attributes['class'][] = '';
    }
    if ($i == $num_items) {
      $attributes['class'][] = '';
    }
    if ($term['active_trail'] == '1') {
      $attributes['class'][] = 'active-trail';
    }
    if ($term['active_trail'] == '2') {
      $attributes['class'][] = 'active';
    }

    // Alter link text if we have to display the nodes attached.
    if (isset($term['nodes'])) 
{ 
    $term['name'] = $term['name'] . ' (<span>' . $term['nodes'] . '</span>)'; 
}

    // Set alias option to true so we don't have to query for the alias every
    // time, as this is cached anyway.
    $output .= '<li' . drupal_attributes($attributes) . '>' . l($term['name'], $term['path'], $options = array('alias' => TRUE));
    if (!empty($term['children'])) {
      $output .= theme('taxonomy_menu_block__' . $config['delta'], (array('items' => $term['children'], 'config' => $config)));
    }
    $output .= '</li>';
  }
  $output .= '</ul>';

  return $output;
}

我这对于引导 cdn 类是什么，我已经将函数移到了 drupal 主题的 template.php 上，但是 span 元素在浏览器中是纯文本的

试试这个：

if (isset($term['nodes'])) 
{ 
    $term['name'] = $term['name'] . ' (<span>' . $term['nodes'] . '</span>)'; 
    echo $term['name']; // To see the output
}
