    Sal Ferrarello: Introduction to Post Meta

    WordCamp Philadelphia 2018Speaker: Sal Ferrarello

    Sal Ferrarello: Making Your Code Easy To Extend

    WordCamp Baltimore 2017Speaker: Sal Ferrarello

    October 23, 2017 — Plugin angst – That horrible feeling when you find a plugin that does *almost* exactly what you want but to get the right behavior you’ll have to change some code. And by changing the code, you lose the ability to update the plugin, which means missing out on security patches, bug fixes, and new features.
    We’ll look at how plugin authors can help you avoid this angst by writing extensible code. Plugin behavior can then be modified without making changes the original code.

    Sal Ferrarello: Getting Started with Composer

    WordCamp Philly 2015Speaker: Sal Ferrarello
