Using bp_parse_args() to filter BuddyPress template loops

In BuddyPress 2.0, one of the coolest things for developers is the bp_parse_args() function. This function is copied over from our cousin, bbPress.

What this allows developers is the chance to filter various parameters before they are passed for further rendering.

I’ve just created a codex article explaining how to use bp_parse_args() to filter BP’s template loops here:
http://codex.buddypress.org/plugindev/using-bp_parse_args-to-filter-buddypress-template-loops/

If anyone has any questions about the codex article, please drop a comment below and I’ll try to answer it.

Now, go and read the codex and grab a slice of pizza!

Hi Ray,

This is extremely useful stuff, also for theme developers! I have a question about this.. I’ve been looking at several ways to be able to “clean up” the stream WITHOUT actually blocking entries from being added (like the block activity types plugin does). If I understand correctly you could use this new filter to achieve this.

Could you provide a basic example where you’d exclude certain activity types from being shown in the activity stream? Let’s say we want to hide new friendship activities and new sign-up activities.

And an additional question.. could you maybe use these filters with Ajax and work towards a way to filter where we can pass multiple arguments? So a user could choose to show New Blog Posts AND New Comment AND New Forum Topics and exclude the rest?

I’m excited about this stuff, so excuse all my questions (as a non-developer but theming geek 🙂

  Hey Bowe,
  
  Apologies for the extremely late reply!
  
  Could you provide a basic example where you’d exclude certain activity types from being shown in the activity stream? Let’s say we want to hide new friendship activities and new sign-up activities.
  
  BP currently doesn’t have the ability to exclude activity types in the activity loop. However, you are able to include activity types to be shown. So you could do the inverse of what you wanted to do.
  
  In the example below, you would list out all the activity types that you would want shown in the activity stream while omitting activity types that you wouldn’t want shown:

  It would probably be better to block the activity items you don’t want shown from being recorded. Then, you wouldn’t have to resort to filtering the activity loop.
  
  So a user could choose to show New Blog Posts AND New Comment AND New Forum Topics and exclude the rest?
  
  This is possible, but doesn’t require using the new bp_parse_args() stuff. Let’s say you wanted to create an activity dropdown filter called “New Content” and filtering the types you just mentioned. Here’s an example:

  Again, apologies for the late reply!
