Creating custom capabilities

I am considering upgrading to S2MemberPro, but before I do, I want to know that the free version is robust and works well and is easy enough for me to use (since it’s the foundation of the Pro version) before buying Pro, so I’m wondering if you can tell me where I could find help with this issue (I can’t find anything in the free Knowledge Base or Forum):

If I enter a custom value, such as “uwlpg1″ to the “Require Custom Capabilities?” field on a page, doesn’t that create the custom capability value that I would use in PayPal buttons and custom capability short codes and php codes? Or is there somewhere else that a value is entered in order to generate a custom capability value?

I tried the above method (entering “uwlpg1” in the “Require Custom Capabilities” field on a page), and then entered a short code on the page like this:

[s2If current_user_can("access_s2member_ccap_uwlpg1")]
Content for this capability (e.g. link to a page).
[/s2If]

But I get an error message at the top of a page (Login Welcome Page) where I have several access restrictions. This is the error message:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘current_user_can’ was given in /home/content/70/8904870/html/ultimateweightlossprotocol/wp-content/plugins/s2member/includes/classes/sc-if-conds-in.inc.php on line 138

What is the correct way to establish a custom capability value that will work in the short codes? I’ve read over the sections related to custom capabilities in the API Scripting area in S2Member and can’t see what I might be missing. It seems like your documentation on establishing custom capability codes might be either thin or my installation has a bug.

First thought, try removing the \”\’s in the current_user_can() function.

I don\’t see any quotes in the example given in s2member aip/scripting examples like this one:

[s2If current_user_can(access_s2member_level1)]
//content here
[/s2If]

Hope that helps,

EDIT: I just copy/pasted your code in my version and it works fine (without the \”). I don\’t get any errors. It may be a corrupt file or something when you installed it. I suggest re-installing to see if that fixes the problem.

Do you mean uninstall and re-install S2Member? If so, is there a way to back-up the settings, or will I have to recreate them manually?

It sounds like you\’re saying that the short codes should not have quotation marks where I placed them around the custom capabilities portion of the command, and when I looked back at the \”Custom Capabilities (Packages)\” tab, there are several occurrences at the top of the page where quotation marks are used:

Each s2Member Level ( aka: s2Member Role ) provides the Capability current_user_can(\”access_s2member_level0\”), 1, 2, 3, 4, where access_s2member_level[0-4] is the Capability associated with each Role; and Membership Levels provide incremental access ( i.e. Level #4 Members can also access content at Levels 0, 1, 2, and 3 beneath them ).

Capabilities using current_user_can(\”access_s2member_ccap_music\”) and current_user_can(\”access_s2member_ccap_videos\”).

However, when I look at the examples further down the page, it looks like quotation marks are used in php code, but not in the short codes. Is that the case? (that quotation marks ARE used in php code, but not in short code?)
