BuddyPress Groups API

BuddyPress Group Extension API Andy Peatling @apeatling buddypress.org/developers/apeatling

What’s API? Are People Interested Angry People Inc. Application Programming Interface All Peanuts Inside Another Pointless Idea

It’s all about Abstraction

Me (developer) Writing code without an API More complex and scattered code When the app changes, my code breaks! Usually quite “hacky” Application

Me (developer) Writing code using an API Simple and standardized code API When the app changes, the API takes care of it, your code doesn’t break! Lower barrier for entry Application

A Real World Example Fetch posts in WordPress without an API Work out the query you need, check the database? SELECT ID FROM wp_posts WHERE post_type = 'post' AND post_status = 'publish' ORDER BY post_date DESC LIMIT 20 Loop the results manually foreach ( (array) $posts as $post ) .... What about security? Oh dear... wp_esc() ... wp_filter_kses() ??

A Real World Example Fetch posts in WordPress without an API If the database schema changes in a new version of WordPress, your code breaks. If the post fields change in a new version of WordPress, your code knows nothing about them. Your code is hacker fodder.

A Real World Example Fetch posts in WordPress using the API Fetch the posts you need, who cares about the database? get_posts( ‘numberposts=20’ ); Loop the results using the built in WordPress loop <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); Security? No worries. the_content(); the_title(); the_tags();

A Real World Example Fetch posts in WordPress using the API No need to worry about database changes, get_posts() will update in new versions of WordPress. If new post fields are available, you can use them in your code using new template tags. Your code is safe.... hopefully. :)

The WordPress API is Everywhere wp_authenticate() get_posts() WP_Widget get_usermeta() add_filter() add_action() current_user_can() update_usermeta()
