BuddyPress.org

I’m running wpms install with buddypress (wp 3.9, из 1.9)

I’m using code below to make main website protected from not logged in users, and let them to visit only landingpage, registration and activation pages. Registration and activation pages are native buddypress pages.

<?php
function shield() {
if( !is_user_logged_in() ) 
{ if( !is_page( array( 'landingpage', 'registration', 'activation')) ) 
{ wp_redirect( 'landingpage' ); exit(); }
}
}
add_filter('get_header','shield',1);
?>

Code works perfectly. Except that it ends to redirection loop errors on registration and activation pages….

I think it’s because buddypress has similar functions for this kind of pages for logged in users – to redirect them away from those two.

How to fix it? I would like to protect part of the site. But let registration.

PS: To prevent questions about login – it’s on landingpage.

For the most part, Buddypress is great! However, as a theme/php developer, its great strengths (ease if use and installation) also become its weakness. Customizing the Activity feed beyond CSS (ie: building your own template), the labyrinth of procedural code, the dated codex, and the hooks and actions becomes quite the challenge.

Now, if you just want to customize the title, change colors, or modify the layout a lot of that can be achieved by CSS.

But if you want to access activity data beyond it’s intended scope (say, for mobile app development, API layers, or just becasue you want to get your hands on it!) then this guide is for you!!

Prerequisites:
Basic PHP Knowledge
WP Theme development experience (even child-theme)
Experience using the fabled ‘functions.php’ and template tags.

Ok, so if you meet the prerequisites allow me to share with you the best bp function ever (well, maybe not ever, but the best one for me, right now, haha)

take a look at /wp-content/plugins/buddypress/bp-activity/bp-activity-functions.php – line:900ish and say hello to pandoras box!

This magical function, dubbed bp_activity_get() will allow you to get just about every piece and part of an activity feed even OUTSIDE of a bp loop. Not only that, but it allows for you to run filters through it, meaning you can grab activities by group, by member, sitewide, or just ONE activity if you want.

Here’s a sample function I made that grabs the 8 most recent activities and puts the keys I found important into an array. If you’re familiar with the wp $post object, this is quite similar:

/**
* Dumps a list of the latest activities. May be used with pagination by setting $current_page
*
* @posts_per_page	INT, Default is 8.
* @current_page		INT, which page you are on, Default is 1.
*
* @var_dump 	ARRAY, activity items.
*/

function get_latest_activities($posts_per_page=8,$current_page=1) {
	$args = array (
		'page'	=>	$current_page,
		'per_page' => $posts_per_page
	);
	$pre_rec = bp_activity_get($args);
	$activities = $pre_rec['activities'];
	$results = array();
	foreach ($activities as $activity) {
		$record = array(
			'ID'		=> strip_tags($activity->id),
			'TYPE'		=> strip_tags($activity->type),
			'TIME' 		=> strip_tags($activity->date_recorded),
			'AUTHOR' 	=> strip_tags($activity->display_name),                
			'TITLE' 	=> strip_tags($activity->action),
			'CONTENT' 	=> strip_tags($activity->content),
			'ITEM_ID'	=> strip_tags($activity->item_id),		
			'REL_ID'	=> strip_tags($activity->secondary_item_id),		
		);
		array_push($results, $record );
        unset($record);

    }
	foreach ($results as $record) {
		var_dump ($record);
		print "<br>###################<br>";	
	}	
}

So now, I could place any piece of the data, anywhere I want. You could also (if you wanted to) create template tags that are much more custom. You can also get the data outside of the loop, throw it in the <head> section for SEO purposes, and on and on and on. Maybe you want to throw a widget on your site with the latest activities? This method will do it.

Let me know if you have any questions, I hope this helps, because it took me way too long to figure this out and the current documentation did not help.

I would like to build a site that highlights different types of members. For instance, I run a site on a chronic illness on which I would like to be able to target people who’ve recovered. I envision building a questionnaire – asking them what worked, what didn’t work – and then highlight those members with their answers in a separate section.

So, I need to be able to ask distinct groups separate questions which I assume I can do with custom fields and then differentiate them from the rest of members. Is this possible in BP?
