Question

I am trying to get a preprocess function to work on my drupal 7 site and am having some difficulty. I was given this.

function fource_preprocess_page(&$vars) {
  if ($vars['is_home']) {
    $path = drupal_get_path('themes', 'fource');
    drupal_add_js($path . 'js/image_scale.js');
    $vars['scripts'] = drupal_get_js();
  }
}

-fource is the name of my theme
-I am using the page–home.tpl file as I am using panels for the homepage
? Not sure about the path… (‘themes’, ‘fource’)
? Also need to add the css file.

I have no idea what I’m doing here so the most detailed explanation would be greatly appreciated.

Answer 1

I think in Drupal 7 you actually want to do this in theme_preprocess_html(). In your theme’s template.php file you’ll need something like this:

function fource_preprocess_html(&$vars) {
  if($vars['is_front']) {
    drupal_add_js(drupal_get_path('theme','fource').'/js/image_scale.js');
  }
}

The call to drupal_get_path('theme','fource') just asks Drupal for the full path to your theme, then you just tack your JS file name on the end.

To be honest, I’m not sure about is_home vs. is_front, but Google probably knows.

There’s also a function drupal_add_css (documented here).
