Hello,

This hook doesn't work in my template.php (my custom theme)

I want to do this :
http://www.braahm.be/posts/tuning-taxonomy-pages-page-manager-panels-vie...

<?php
function mythemename_entity_info_alter(&$entity_info){
  $entity_info['node']['view modes']['taxonomy_listing'] = array(
    'label' => t('Taxonomy listing'),
    'custom settings' => TRUE,
  ); 
}
?>

What is the solution ?

You need to add that in a custom module, not in template.php.

Firstly you need to include this in a custom module, not template.php, eg.
function custommodule_entity_info_alter(&$entity_info){

Initially I couldn't get this working either, once the module was enabled the view mode was there enabled in the checkbox list, but was missing the secondary tab/button to customise it.

Cleared all caches etc., no luck.

As I wanted to only use this mode in a ubercart product, I tried changing the entity 'node' to 'product' in the code. My view mode tab now appeared, but errors abounded.

Switched it back to 'node' and tab stayed there, and now works fine with no errors...

Can anyone explain this? Is it something to do with the way that ubercart declares/creates the product content type in the product module?

You need to disable/re-enable the module

I found that disabling the module that implements hook_entity_info_alter(), then re-enabling it, allows the tab for the newly created view mode to appear on the Manage Display page.

Hope this helps someone!
