Fatal error: Call to undefined function

I'm unable to reproduce this error. If you can provide steps on how you got to that error, I can look into what's causing it.

Try this patch and see if it works. Force including the registration forms include file since we use their validation handler. FYI this patch is for the latest commit, so it won't be available as a tar file yet. You'll have to grab it from the repo.

Just grab the latest commit (414b544). I added some other changes in that should make things work all around better. The patch failed because it was testing it against alpha2, but the patch was for the latest commit (dev branch basically).

All you need to run in git is just:

git clone --branch 7.x-2.x http://git.drupal.org/project/commerce_registration.git

Once you do that, it will download the files into a new directory "commerce_registration" in whatever directory you are working in. Then just copy the directory to your server (you can ignore the .git folder) and that will be the latest committed files I have.

Yes, the 7.x-2.x branch has the fix.

Make sure you have the latest version of Entity Registrations as well (alpha4).

I'll test this tomorrow and see if it's something in my code.

Leaving this as postponed for now until I can get more info on what's causing it.

I've got exactly the same error.

Very similar problem here:

Fatal error: Call to undefined function registration_registrations_settings_form() in /Users/tom/workspace/concern7/profiles/concern/modules/contrib/commerce_registration/includes/commerce_registration.forms.inc on line 38

This is with registration-7.x-1.0-beta1 from yesterday, and latest git code of commerce_registration. This happens when trying to access node/[nid]/registrations/settings. WSOD.

Looks like Registration has changed the name and signature for those form functions. Patch updated commerce_registration to work with latest registration beta1

Patched in the latest commit. Doesn't show I committed it as I just reinstalled pretty much my entire computer and forgot to setup my git configs.

Going to set as fixed for now. If the issue comes up again just reopen.

I am using latest dev version of commerce_registration and I have this problem as well. It seems that not all of this patch got in and I was getting the same errors.

Here is the patch I created that works for me.

Same problem. I downloaded the latest release of dev (7.x-2.x-dev) applied the patch in #20, but still get the same error when trying to enable registrations in the product:

Fatal error: Call to undefined function commerce_registration_registration_settings_form_validate() in site/includes/form.inc on line 1443

Registration 7.x-1.0-beta2
Commerce Registration Integration, 7.x-2.0-beta1+1-dev (patched with #20)

Let me know if there is any other info I can provide.

Works fine for me. I cloned the latest 7.x-2.x branch and applied the patch in #20 with no problems, and verbose output saying that it was cleanly applied. I have yet to do exhaustive testing, but all seems well!

Update: Fully tested and it works fine with this patch. This is such a great module! The possibilities that this module and registration provide are veritably endless! I was going to do all this custom with rules, views, etc. but this approach saved me tons of time. Thanks so much!

This is driving me a little crazy. I think the problem (#21) I'm seeing stems from the syntax of the module_load_include calls in commerce_registration.module on line 372 and 375, which preface the includes directory with "/", e.g.:

      if (!function_exists("registration_entity_settings_form")) {
        module_load_include("inc", "registration", "/includes/registration.forms");
      }

If I force load these files at the start of the module without the "/":

module_load_include('inc', 'registration', 'includes/registration.forms');
module_load_include('inc', 'commerce_registration', 'includes/commerce_registration.forms');

I don't see the undefined function error(s). I'm on a Mac, which might explain why not everyone sees the problem (?)

However, I do get a different error now after saving a product with an attached registration field:

Notice: Undefined index: reminder in registration_entity_settings_form_validate() (line 562 of /sites/all/modules/registration/includes/registration.forms.inc).

Not sure if this is related or not.

This should be fixed in the latest commit. I removed all the initial backslashes on all module_load_include calls so that should be fixed. I also fixed the settings form so the Undefined Index error is gone.

OK, I pulled the latest commits from dev, and re-tested. The errors I reported in #24 are gone. Excellent.

However, I now get a new error during checkout when moving from Shipping to Review:

EntityMetadataWrapperException: Unknown data property commerce_product. in EntityStructureWrapper->getPropertyInfo() (line 339 of /sites/all/modules/entity/includes/entity.wrapper.inc).

In limited testing, this seems to happen only when there has been some shipping rate applied. I can do some more testing with different kinds of products tomorrow. Let me know if you want me to open this in a new issue.

Also - I notice that the patch in #20 above is not in dev - not sure it it should be or not, but just wanted to mention it.

The exact patch is not in dev, but the issues it addresses are fixed in dev currently.

The Exception you're getting is most likely due to a line item check. Going to mark this as fixed and open a new issue with that error.

@jpontani - I was testing #1601268: commerce_product metadata property doesn't exist on all line items again, and started to run into the undefined function error again today. I cleaned up some references to form function signatures that have changed, added 'reminder' into the product ui form, and ended up changing module_load_include to form_load_include inside commerce_registration_form_alter. I'm not sure if this is related to caching or not, but this was the only I could resolve the undefined function error, without just forcing commerce_registration.forms.inc to load.

Things are working well for me now, except for the path error mentioned in 1601268.

Please review the patch carefully and use only what makes sense to you.

Just switching status to needs review.

Everything looked fine. I changed a few extra calls that were not part of your patch to use form_load_include as well, as they are part of forms. Wanted to make sure the include loading is consistent with forms, so hopefully this resolves any form caching issues. Pushed in the latest commit (42e674a).

I messed up the git commit attribution, figures :/

I just downloaded the Kickstart (full pkg with Core). I already had PHP, MySQL & Apache (on Windows x64) running with an active website. After many required changes to php.ini, I finally got to "configure site" and got the error message noted in this forum:
Fatal error: Call to undefined function commerce_currencies() in
E:\DJs Documents\public_html\drupal\profiles\commerce_kickstart\commerce_kickstart.install on line 240

Since I have no products, (this is a NEW Drupal-commerce site), I don't know if the suggested patch is relevant (now that 2 years have gone by, I assume the patch is part of the distributed code). Any ideas what I can try? I am new to Drupal, PHP, MySQL, Commerce and Kickstart. (But I AM a programmer & have built queries and DBs with MS Access). I did create a simple DrupalGardens site I hope to add to Commerce.
