Question

我的页面顶部有图像问题。当url是网站名称/菜单时，会显示image。当url为websitename / node / 164时，image消失。

因此，当级别为1时会显示image，但当url-level高于1时，image会消失。

我在ZURB-Foundation使用Drupal-7主题。这是我在page.tpl.php

中使用的代码

<!--.page -->
<div role="document" class="page">
<?php
// Create a variable to hold the full path, in our theme, to the image.
//   path_to_theme() takes care of creating the correct path for the active theme (which is  likely your own custom one)
$my_static_banners = path_to_theme() . '/images/header/';
?>
<?php
if ($handle = opendir(path_to_theme() . '/images/header')) {
/* This is the correct way to loop over the directory. */

while (false !== ($picture = readdir($handle))) {
  if($picture != "." && $picture != ".."){
    $pictures[] = $picture;
  }
}
$random = array_rand($pictures,1);
$header_picture = $pictures[$random];
closedir($handle);
}
?>
<!-- MENU-->
<!--.l-header region -->
<header role="banner" class="l-header" >
<div class="header-image" style="background-image:url(<?php print     $my_static_banners.$header_picture ?>)">
</div>
</div>
...

请尝试减少主题图层中的PHP代码量。

在您的页面模板中：

<div role="document" class="page">
<!-- MENU-->
<!--.l-header region -->
<header role="banner" class="l-header" >
  <div class="header-image" style="background-image:url(<?php print $header_image; ?>);">
  </div>
  </div>

在主题中的template.php内或自定义模块中：

/**
 * Implements hook_preprocess_page().
 */
function THEME_NAME_preprocess_page(&$variables) {
  $variables['header_image'] = FALSE;
  $images = _THEME_NAME_get_images();
  if ($images) {
    $random = array_rand($images, 1);
    $variables['header_image'] = $images[$random];
  }
}

/**
 * Get images within a particular director.
 *
 * @return array
 *   An array of images for the header.
 */
function _THEME_NAME_get_images() {
  $dir = drupal_get_path('theme', 'THEME_NAME') . '/images/header';
  $images = array();
  if (is_dir($dir) && $handle = opendir($dir)) {
    while (FALSE !== ($filename = readdir($handle))) {
      if ($filename[0] != '.') {
        $images[] = $dir . $filename;
      }
    }
    closedir($handle);
  }
  return $images;
}
