Give specific post/page access with PHP

I’d like to write a plugin that will grant specific post/page access to certain members. I found lots of documentation on how to determine IF users have access to content, but I’m trying to actually set that answer with code. Is this possible?

Hi Brett.

I researched this for a bit and found a hook you can try: [hilite mono]"ws_plugin__s2member_sp_access_excluded"[/hilite].

http://www.s2member.com/codex/stable/source/s2member/includes/classes/sp-access.inc.php/#src_doc_line_103

Notice it has 3 arguments, which is important when you use add_filter.

I hope it helps. :)

I’m going to give this a try. Do you have any idea where this happens in the execution order? More to the poin, I’m wondering if I can add an action to the “template_redirect” hook in which I add this filter. Obviously, “template_redirect” has to happen BEFORE the filter gets applied for this to work.

No, I’m not familiar with the execution order for it, but I’d guess it happens before a redirection because the access restriction is checked before redirecting a person for not having the right access for that content.

I just realized that my question was a little bit strange. I was thinking in terms of do_action (which would need to get called in the right order) but this hack is using a filter, so it doesn’t need to be wrapped in another hook…

Good news:
It looks like the filter strategy is going to work. I couldn’t get it to work with “ws_plugin__s2member_sp_access_excluded” but I AM having luck with “ws_plugin__s2member_sp_access” (same link as above, just a couple lines lower in the code).

For anyone else who stumbles upon this thread, my code looks something like this:

//my custom capability is named "student"
add_filter("ws_plugin__s2member_sp_access", "special_access",1, 3 );

function special_access() {
		
		global $post;
		$current_id = $post->ID;
		$post_type = get_post_type($current_id);
		
		//add conditional test for whether stop-student is true/false
		if ( current_user_can("access_s2member_ccap_student") ) {
			return true;
		} else {
			//tough luck buddy
		}
}

But, that hook is after the page was excluded from the Specific Page restriction.

Did you try something like this with the hook I mentioned before?

[hilite pre_code]
add_filter('ws_plugin__s2member_sp_access_excluded', 'special_access', 1, 2);

function special_access($excluded, $vars) {
if (current_user_can('access_s2member_ccap_student')) {
$excluded = true;
return $excluded;
}
[/hilite]

or even

[hilite pre_code]
add_filter('ws_plugin__s2member_sp_access_excluded', 'special_access', 1, 2);

function special_access($excluded, $vars) {
return (current_user_can('access_s2member_ccap_student') ? true : $excluded);
}
[/hilite]

Huh. I’m going to try your version, but let me clarify one thing. Your code blocks students, right? I think I need to reverse it to allow students by setting $excluded to FALSE. Thanks for your help.
EDIT: No, your code works as it was written. I guess I need to revisit the source to better understand what’s going on.
EDIT: Right. I got confused by the variable name “excluded”. It doesn’t determine whether or not the user IS (=true) or IS NOT (= false) excluded from accessing the specific post/page. Rather the opposite. It determines whether the user is excluded from the sp post/page access requirements.
