- 2. What’s API? Are People Interested Angry People Inc. Application Programming Interface All Peanuts Inside Another Pointless Idea
- 4. Me (developer) Writing code without an API More complex and scattered code When the app changes, my code breaks! Usually quite “hacky” Application
- 5. 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
- 6. 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() ??
- 7. 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.
- 8. 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();
- 9. 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. :)
- 10. The WordPress API is Everywhere wp_authenticate() get_posts() WP_Widget get_usermeta() add_filter() add_action() current_user_can() update_usermeta()
