How to get data about previous page?

I have a “login or register” page, that displays either a login form or other content, depending on whether the user is logged in or not (duh!).

Now, from this page, I’d like to redirect the user upon login, to the post he was trying to access, only if he has the required ccap to view this post.

I know how to get the user’s ccap(s) but:
1. How can I get the ccap required for the previously requested post
2. How do I build the redirection url?

Hope that’s just clear enough… as you can probably tell, I’m not a native English speaker.

Thanks for your help!

EDIT: I’ve been a bit quick pretending that I knew how to get the user’s ccaps (and I meant display them)…

I thought the whole answer was here: http://www.s2member.com/forums/topic/cant-receive-the-users-ccaps-values/

…but if I do as suggested and write:

<?php
$user_capabilities = get_user_option('capabilities', S2MEMBER_CURRENT_USER_ID);
print_r($user_capabilities);

$user_ccaps = explode('|', $user_capabilities);
echo $user_ccaps[1];
?>

I only get the result of print_r:

Array
(
[s2member_level1] => 1
[access_s2member_ccap_module1] => 1
[access_s2member_ccap_module2] => 1
)

Nothing is echoed. I’ve tried other delimiters, no luck. Really can’t figure out how to echo all the ccaps contained in the array, or any of them actually. I’ve tried a bunch of stuff suggested on php.net and stackoverflow, no luck either. Needless to say I’m a PHP ninja… ;)

Anyway, that’s just another question to add to the 2 previous ones.

Thanks for your assistance, the explode() function works miracles on my brain! ;)

1. How can I get the ccap required for the previously requested post

[hilite path]Dashboard -› s2Member® -› API / Scripting -› Membership Options Page Variables (MOP Vars)[/hilite]

Really can’t figure out how to echo all the ccaps contained in the array, or any of them actually.

Something like this? (not tested)

[hilite pre_code]
foreach ($user_capabilities as $cap => $v) {
if (strpos($cap, 'access_s2member_ccap_') !== false)
echo $cap . "\n";
}
[/hilite]

Thanks, Cristiàn!

1. Okay… I missed that.

2.

<?php
$user_capabilities = get_user_option('capabilities', S2MEMBER_CURRENT_USER_ID);
foreach ($user_capabilities as $cap => $v) {
	if (strpos($cap, 'access_s2member_ccap_') !== false)
		echo $cap . "\n";
}
?>

Returns:

access_s2member_ccap_module1
access_s2member_ccap_module2

Which is a good start ;) but, as you can guess, what I’d like to display is:

You have access to module 1, which contains:
[Links to posts included in module 1]

Which is a good start ;) but, as you can guess, what I’d like to display is:

Well, then you don’t need to echo the ccaps. Have a list of links for each module inside conditionals for each ccap, for example. The conditions can just check if the key with the ccap is set, for example:

[hilite pre_code]
if(isset($user_capabilities['access_s2member_ccap_module1'])) {
// Links to Module 1 pages.
}
[/hilite]

Well, Cristiàn… you’re totally right.

I don’t know if you’ve ever been in this stupid state, where you don’t even remember why you have to do something, but all you “know” is you have to? It generally means you are knackered and you need a serious break… I went out of the stupid state yesterday, and wrote this awesomeness in my mu-plugins:

<?php function you_can_access()
	{
		echo ("<p><strong>Hi " . S2MEMBER_CURRENT_USER_FIRST_NAME . "!</strong></p><p>You currently have access to:</p>");
		if(current_user_can('access_s2member_ccap_module1')) 
		{
			echo ('
			<h4>Module 1</h4>
			<ul>
			<li>Content 1</li>
			<li>Content 2</li>
			<li>Content 3</li>
			</ul>
				');
		
		
		if(current_user_can('access_s2member_ccap_module2')) 
		{
		// Guess what?
		}

I’ll echo the ccaps… next time. ;)

Thanks again!
