Adding Custom Capability Issues

Ok. I am going out of my mind here. I think I have tried everything I know to do and still am unable to get this function to work. Here is what i want to do:

I am using s2member for my membership plugin. When I sign a person up using the userregistration plugin, I select s2member_level1 as the role. If I just sign up as is, the following is in the wp_capabilities metakey field:

a:1:{s:15:"s2member_level1";s:1:"1";}

Now, if I add the custom capability manually, I get this in the wp_capabilities metakey field:

a:2:{s:15:"s2member_level1";s:1:"1";s:26:"access_s2member_ccap_test";s:1:"1";}

So, I have tried the following code in the functions.php field:

add_action("gform_user_registered", "add_custom_user_meta", 10, 3);
function add_custom_user_meta($user_id, $config, $entry){
add_user_meta($user_id, 'wp_capabilities', $entry[22]);
}

I have also tried:

add_user_meta($user_id, 'wp_capabilities', 'access_s2member_ccap_test');
add_user_meta($user_id, 'wp_capabilities', "access_s2member_ccap_test");

$custom_cap = 'access_s2member_ccap_test';
add_user_meta($user_id, 'wp_capabilities', $custom_cap);

$user = $user_id;
$user->add_cap("access_s2member_ccap_test");

And I have even tried adding a custom meta in the user registration field and naming it "wp_capabilities". No go on that either.

Every thing I have tried has not resulted in adding the custom capability to the user profile. The user registers just fine, but only at the role level.

Also, how do I only target specific registration forms as using "gform_user_registered_6" does not work.

Thanks for all your help. The form I have been working on is form id 6, website is https://www.freeclassifiedproducts.com/sign-up-for-a-credit-repair-membership?s2-ssl=yes

Yes, wp_usermeta. Metakey is "wp_capabilities". The value for a normal level 1 user after registration is:

a:1:{s:15:"s2member_level1";s:1:"1";}

The value for a level 1 user with a custom capability "access_s2member_ccap_test" is:

a:2:{s:15:"s2member_level1";s:1:"1";s:26:"access_s2member_ccap_test";s:1:"1";}

Thanks

Unfortunately, that won't work for my set up. I have a free membership and a product that uses the custom capability for registration purposes. I have to be able to add the custom capability some way other than manually.

Thanks for the help, but I gotta do it the way we have previously discussed.

Thanks. So is what I am asking to do just not possible or what? I tried using the instructions on wordpress.org and this site to no avail.

Thanks again for your support.

I finally got it. Here is the solution I used:

add_action("gform_user_registered", "add_custom_user_meta", 10, 3);
function add_custom_user_meta($user_id, $config, $entry) {

wp_set_current_user( $user_id );
$user = wp_get_current_user();
$user->add_cap ("access_s2member_ccap_test");
}

i know the wp_set_current_user fuction returns the WP_user object, I just don't know how to access the return value as I really don't know PHP.

Now, my last question here, how do I perform this routine on select registration forms? For instance, only form 6, but not on form 8?

I hate to show my ignorance here but how do I use this code snippet?

Do I put my function between the if and return, or do I add this code in my function.

I know, NOOB. Thanks for the excellent support.

Got it, thanks for all your help.
