This forum is for module development and code related questions, not general module support. For general support, use the post installation forum.

THIS FORUM IS NOT FOR "What module..." or module support questions-- it's for module development and code related questions.

The module development and code questions forum is intended to aid those who are developing modules or writing code for Drupal.

Please note that this forum is also not intended for "Is there a module that does..." or "I need help with module x..." questions. It's also not a place to ask developers to write your code for you. Please respect this.

Please do not post general discussions intended to target module developers. If the question you have isn't specifically related to writing a drupal module, please post it in a more appropriate forum.

  • If you you have drupal installed already and are seeking a module that does a specific task, have a question about a specific module and what it does or if it will fit your use case, please place your questions in the Post installation forum.
  • If you have a problem or question about a specific module, you should create an issue in the module's issue queue (after checking for an existing issue first).
  • If you don't have drupal installed yet, please place your questions in the Before you start forum.

How to display validation errors to checkout panes

Entity API - Bundle Menu with Wildcard

Hi Guys,

I'm trying to get the bundles of my entity type to appear in the admin menu, however they do not appear. I have the following code and I am not sure if there is something that I have missed?
