Notice : Undefined index: title in template_preprocess_node()

@Dakwamine, I also got the same error as shown above, in my attached patch I provide the solution to remove this error. Can you please try with my patch. Let me know your views for the same.

Thanks!..

Your patch is not working saurabh.dhariwal.

Note the code comment in ptoc.module:

/**
 * Implements template_preprocess_HOOK().
 *
 * Call default preprocess function.
 * According to the docs on hook_theme(), this should not be needed.
 */
function template_preprocess_ptoc_node(&$variables) {
  template_preprocess_node($variables);
}

I think that problem was fixed in #2559825: Preprocess functions from base hooks not triggered for theme hooks not using the __ pattern, so I can just remove the two preprocess functions.

Please try the attached patch.

It's working !

Thanks

@jhereck:

I will take that comment as the equivalent of RTBC. Next time, please update the issue status to make it official. Standards for contrib modules, especially those with small user bases like this one, are lower than for Drupal core.

Thanks to everyone who participated on this issue!
