Frequently Asked Questions

What functions should I memorize?

Focus on: get_posts(), get_post(), get_post_meta(), update_post_meta(), current_user_can(), get_option(), update_option(), and hooks like add_action()/add_filter().

When should I use WP_Query vs get_posts()?

Use WP_Query for complex queries with full loop support. Use get_posts() for simple queries. WP_Query is more flexible and powerful.

What's the difference between actions and filters?

Actions execute code at specific times. Filters modify data and return it. Both use hooks - they're the WordPress plugin API.

How do I store plugin settings?

Use get_option() and update_option() for site-wide settings, or get_post_meta()/update_post_meta() for post-specific data.

What does sanitize_text_field() do?

It removes potentially harmful code from text input. Always sanitize user input before storing or displaying it.

Is there a complete WordPress function reference?

Yes! Check developer.wordpress.org for comprehensive documentation. This tool covers the most commonly used functions.
