I intend to create a slideshow in front page of my theme to show all images in custom directory, I try to use file_scan_directory and drupal_get_path in below codes to get any non static images path and display that images automatically without any need to calling each one of them separately:
Theme Name.theme:

function MyThemeName_preprocess_page(&$variables) {
$mask = '/\.(?:jp[e]?g|gif|png)$/i';
$files = file_scan_directory(drupal_get_path('theme', 'Theme Name') . '/assets/img/orbit', $mask);
$variables['files'] = $files;


{% for file in files %}
<img src="{{ file.uri }}" width="100%" height="100%" alt="{{ file.name }}"/>
{% endfor %}

I would be happy to hear what is the problem with the codes and what is the right way to load that slideshowe pictures?

  • Do you have the above code in a preprocess function? Such as THEME_NAME_preprocess_page(&$variables)

    WRT to the best way to do something. I think it depends on your use case. Typically, I wouldn't go about this by calling pictures in the theme unless they are never to be edited by the client in the CMS and there isn't a need for other slideshows on the site. An example of how this could be accomplished is to create a custom slideshow block with an image field that allows X amount of images. This would allow for all the content to be controlled in the CMS, and other slideshows could be created.

The path will be wrong, file_scan_directory() will return a relative path, you need to add the base_path(), you can set a variable in preprocess:

$variables['base_path'] = base_path();


<img src="{{ base_path }}{{ file.uri }}" width="100%" height="100%" alt="{{ file.name }}"/>
  • Thank you so much for your attention, but can you help me and explain a little more, whatever I try I get error only. Aug 8 '16 at 2:25
  • I don't know what you need me to explain.
