theming

In drupal 7 the recommended method to render output is by using the render api. So no more calling theme(...) directly. Here is a simple example based on the example from the examples module.

If you want to render only one field of your entities you can in drupal 7. Here in the example we have an entity called model which contains an image field.

To render the field you have to specify to the field_attach_view function which entity type, the entity and the view mode you want to use. The function returns a renderable array.

It didnt work for me probably cause I had set up a multi site.
What did I do:
- upload all favicons by ftp to the files folder
- manualy filled in the path files/my_favicon.ico at admin/build/themes/setting/name_of_theme and save

and this worked...

When I used the upload button it didnt work. I didnt investigate it further why my method worked and the other didnt,... (feel free to contact me)

This article explains how to switch your theme. In our example we will switch the theme if one of the fields of our node has a certain value.
Use hook_init() to accomplish this.

<?php
function thuis_sanitech_extra_init() {
  if (arg(0) == 'node' && is_numeric(arg(1))) {
    $node = node_load(arg(1));
    global $user;
 
    if ($node->field_theme_keuze[0]['value'] == 1) {
      //load appropriate theme
      $user->theme = 'affaires';
      init_theme();
    }

You have a node type containing an image field. You want to construct a feed containing the image (and node title) but the image needs to be resized to a format you dont use on the site.

Here is how to do it:

Use imagecache module
Create a preset.
Construct the url where the image would be if the image cache module would generate it. This is the url you will put in your feed.
