This document summarizes a WordPress conference presentation about building applications with WordPress. The presenter discussed how to build powerful websites and applications by disabling the front-end, customizing the admin menu, replacing core settings pages, creating custom roles and capabilities, validating and sanitizing fields, understanding and saving data, adding tooltip help, and using dashboard widgets. Examples of applications that can be built include e-commerce, membership, invoicing, and contact managers. The Piklist plugin was highlighted as a tool that can help with many application development tasks in WordPress.

- 8. ....As WP Engine continues its torrid growth amidst strong customer demand, it has to keep finding ways to deliver world-class support to every customer every day. That means continually improving existing tools and building new ones – quickly. “I have a laundry list of about 40 WordPress dev projects just for this quarter,” Hoanshelt said. “So whenever my team is gearing up for the next one, my Project Manager jokes, ‘Just Piklist it.’” Piklist Customer Success: WP Engine https://piklist.com/case-study/piklist-customer-success-wp-engine/
- 9. Process 1. Build a minimal viable product (MVP) 2. Measure for user behavior 3. Learn for the next iteration
- 10. Disable Front-end Why? Do you need a theme for your application? wp-admin is: Secure Responsive Controlled environment
- 11. Disable Front-end How? function my_no_front_end() { if( !is_admin() ) { wp_redirect( admin_url() ); exit; } } add_action( 'wp', 'my_no_front_end' );
- 12. Change Admin Menu Why? Does your application need the default WordPress items? A cleaner admin is easier to navigate. Don’t make your users work around WordPress. How? Plugin: https://wordpress.org/plugins/admin-menu-editor/ Manipulate: global $menu, $submenu;
- 13. Replace Core Settings Pages Why? Do the default settings pages make sense for your application? A cleaner admin is easier to navigate.
- 14. Replace Core Settings Pages How? Plugin: https://wordpress.org/plugins/admin-menu-editor/ Remove page: remove_submenu_page() Just hides it. Redirect to your new page. Add new page: add_submenu_page() Do not use settings api… saves as a serialized array. Use update_option()
- 15. Create Roles and Capabilities Why? Usually different than standard blog roles. How? Plugin: Members Members
- 16. Disable Author Pages Why? Employees are now authors. Don’t need their own pages. How? Plugin: Disable Author Pages
- 17. Custom Post Statuses Why? Default statuses may not be appropriate for your application. e.g. “Publish”, “Draft”, etc. Examples: “New Order”, “Received”, “Shipped”, etc. How? register_post_status() Registers new post status, but doesn’t change admin UI
- 18. Validate and Sanitize Fields Why? Garbage in… garbage out. Trust no one. How? sanitize_* functions wp_kses functions esc_ * functions Validate with conditionals. Javascript not as secure as server-side validation
- 19. Save Empty Fields Why? Empty fields are a value. Makes it easy to loop over data. Consistency in your object.
- 20. “If you choose not to decide, you still have made a choice” Rush - Freewill
- 21. Understand your data Why? Make sure it is in a useable format. You may want to query it. How? Save data normally: One row per field. Maybe a serialized array is not the best choice? Name your meta keys something meaningful. Look in your database…make sure you understand the data.
- 22. Tooltip Help Why? Explain expected field input. Give users independence. Fewer support calls. How? jQuery UI CSS
- 23. Dashboard Widgets Why? Provide application overview: Sales, Open Orders, etc. Tailor to logged in user. How? https://codex.wordpress.org/Dashboard_Widgets_API
- 24. Piklist piklist.com Custom post statuses Field validation and sanitization Tooltip help Dashboard widgets Replace core settings pages Display fields based on post status/user role Infinite repeater fields. Object relationships Multiple user roles Widgets and shortcodes And much more...
