April 17, 2019 — Hooks and filters are critical part of WordPress.

They are used by the core product and they are what theme and plugin developers use to provide the massive range of add-ons for WordPress.

They are easy to use and let you access the internals of WordPress.

April 3, 2019 — WordPress is known for its extensibility – the ability to change the behaviour of the software without breaking the core code. This is added through plugins and themes.

Understanding how to extend WordPress is essential if you want to develop solutions using WordPress. This talk will teach you how actions and filters work, with some practical and theoretical examples to illustrate their functionality.

Attendees should hopefully come away from this talk with a greater understanding on how actions and filters, or hooks as they are collectively known, can unlock the door to building greater things with WordPress, and as I worked out being able to say “Wow, you can do (almost) anything with WordPress!”.

October 6, 2016 — Prezentacja pozwoli nam zrozumieć, dlaczego rozsądne używanie filtrów i akcji w kodzie jest fajne i jak pozwala potem użytkownikom rozwinąć skrzydła (na bazie kilku przykładów popularnych wtyczek – m.in. jakie cuda można wydusić z Contact Form 7).

February 1, 2016 — Nicht „Was die Welt im Innersten zusammenhält“, sondern was uns WordPress möglichst weit öffnet, das sind die Hooks. Egal ob Theme oder Plugin, um etwas in WordPress zu ändern, zu erweitern, umzubauen und das ohne dass man direkt im WordPress Code ändert, dazu muss man verstehen was Hooks sind und wie diese Funktionieren. Egal ob man ein komplexes Plugin bauen möchte oder nur in seinem verwendeten Theme z.B. den Titel der Beiträge manipulieren möchte.

January 19, 2016 — Good plugins provide actions and filters to allow others (like you!) to modify some of their functionality without having to either create a whole new plugin from scratch or hack away at the original plugin, losing your changes when that plugin gets updated down the road. Learn how to find these actions and filters in other plugins, and use them to bend the plugin to your will.

Learning Outcomes:

Know what actions and filters are, and how they can be used.
Be able to create a functionality plugin to modify another plugin’s functionalities.

December 23, 2015 — This talk will introduce you to WordPress actions, filters and hooks. We’ll cover what they are, how to use them and a few examples in action. Get ready to get more out of your site by powering up your themes and plugins with hook magic!

December 12, 2015 — This talk starts with an explanation of what WordPress action and filter hooks are and how to use them. We then go into the most common and helpful hooks for theme and plugin development. This will include helpful information for people who have not yet begun to use hooks much as well as supply those who do use them regularly with some helpful hints.

December 10, 2015 — This talk will cover a few key “Aha” moments that you should have about the way WordPress works. We’ll talk about things like the template hierarchy, what’s going on in wp-config, where WordPress content is stored (the database vs. the file system), how posts and pages and custom post types are represented in the database, what folks are talking about when they talk about hooks and filters, and just generally review the “behind the scenes” mechanics of how WordPress works. We’ll also touch on a few “tricks of the trade” that you might not realize are out there (version control, staging sites, caching, Vagrant, and other fun tools to make development with WordPress just a little bit easier).

This talk is aimed at designers and new developers who maybe have a few PHP tricks up their sleeves, but still haven’t figured out some of the details behind the scenes.

If you’ve never edited functions.php and don’t know what it is, this probably isn’t a good talk for you just yet. If you’ve written a plugin or modified several .php files in your WordPress themes, this talk will probably be a bit too basic for you. If you’ve set up a child theme before and know what functions.php is, even if you haven’t really used it all that much, or even at all…. you’re probably the exact person who will get a lot out of this talk. And if that’s you, you should be able to walk away with a solid mental model of how WordPress works “behind the scenes” and be in a much better position to do development with it

November 22, 2015 — In this talk, I would like to explore a third option that uses the WordPress hook and filter system to find a comfortable middle ground. Using this method, the index.php file is used as starting point, with all of its output added via hooks and filters. Additional page templates simply add or remove actions from these hooks and filters. This methodology allows new templates to be created quickly and easily. Existing templates can also be modified on a per-use basis. To get the most out of this session, familiarity with WordPress Theme development and PHP are recommended. Knowledge of the WordPress hook/filter system will be helpful, but not required.
