I would like to add a css file when editing content of the content type invoice.

The link is something like this: node/121/edit . I've tried it with it with preprocess_node like this:

function themename_preprocess_node(&$variables) {
    $node = $variables['node'];
    if($node->type == 'invoice')
    {
        drupal_add_css(drupal_get_path('theme', 'themename') . "/css/add.css", array('weight' => 1003));
    }
}

But he doesn't add the css file. When I do a die; in the if structure he executes it...

You're targeting the incorrect preprocess function. By the time preprocess_node is run all our JS and CSS has been included in the top of our html document already.

Use this function instead:

template_preprocess_html

  • But I can't figure out which node type I'm editing with the preprocess_html function ..

  • I'm pretty sure this is wrong - templates work outside-in. drupal_add_css() in a node preprocess hook has always worked for me. Ironically, using drupal_add_css in template_preprocess_html, definitely won't work.
