ClassExtender Problem

I've installed the package and followed the documentation http://bobsguides.com/classextender-class.html However, once I complete the process I can no longer login. I get the following message:

The username or password you entered is incorrect. Please check the username, re-type the password, and try again.

I've done each step in the guide and have emptied the browser cache as well as removed all files in the core/cache directory - reloaded the page and still cannot login. The only way I can login back in, is if I change my user class_key back to modUser.

I am working on this using the latest version of Modx 2.2.14.

Can anyone shed some light on why this is happening? What's missing in the guide or what am I missing? [ed. note: scitekmike last edited this post 12 years, 3 months ago.]

Update: I changed the class_key back to modUser, logged in and checked the error log.. this is what I found:

[2014-06-05 11:05:11] (ERROR @ /index.php) Could not load class: extUser from mysql.extuser.
[2014-06-05 11:05:33] (ERROR @ /manager/index.php) Could not load class: extUser from mysql.extuser.

Why would it not be able to load the class? The plugin is active..

The plugin doesn't load the class, it's loaded because of the value set in the extension_packages System Setting. Can you check to see if there's a reference there to the extuser package?

Do you have the latest version of ClassExtender?

Hi Bob,

First, thanks for replying.

It is the latest version of ClassExtender as far as I know. I installed it via the package management interface today. Looking through and doing a search on the system settings, I don't have anything for extention_packages in the core settings. If I select classextender, there are no settings as well.

Then you don't have it. There are two ways to do this; the best way is to create a snippet with this (or perhaps all in lower case?):


Or you can manually add the setting:
Key: extension_packages
Name: setting_extension_packages
Description: setting_extension_packages_desc
Field Type: Textfield
Namespace: core
Area Lexicon Entry: system
Value: [{"extuser":{"path":"[[++core_path]]components/extuser/model/"}}]

Note the spelling: extension_packages

You should see something like this:

Oops. Well regardless I have no system setting in there for extension_packages. I manually added one it using both you suggestions and still does not work. Still seeing this error in the log:

[2014-06-06 09:52:27] (ERROR @ /manager/index.php) Could not load class: extUser from mysql.extuser

Current system setting:

Key: extension_packages
Name: setting_extension_packages
Namespace: core
Area Lexicon Entry: system
Value: [{"extUser":{"tablePrefix":"ext_","path":"[[++core_path]]components/classextender/model/"}}]

Technically, if I look where the php files are in the core/components/classextender/model/

There are two more directories in that model folder:

core/components/classextender/model/classextender
core/components/classextender/model/schema

With that shouldn't the path to the class file should be:?

Ok, finally got it working by doing the following:

Added the Extension Packages system setting by using the snippet script:



Then updated the value of the system setting with what Bob noted above:



Then, I re-ran the snippet form that was installed with classExtender per the documentation:

Extend modUser
1st not updating the class
2nd updating the class

Reloaded the manager and checked my user account.. the example fields are all there and the manager is functioning as expected.

Thank you both for the insight and additional information.

Suggestion: the information regarding the system setting I think is a big hole in the guide/documentation. It should be stated somewhere in the guide that setting needs to exist *before* you run the form. I'm assuming that the package classExtender when you install it should automatically create that system setting. However, if it doesn't and that setting is missing it creates a wealth of headache trying to understand why it's not working.

I don't think that setting exists until something creates it. On one site, I installed Gallery and that site does have it, with an entry for Gallery.

This is very strange. ClassExtender calls addExtensionPackage(), which contains this code:



So clearly the System Setting is supposed to be created if necessary. You should never have to create the setting or set it yourself. I'll have to check further to see if I can figure out what's going on.
