Ben Doherty: OOP for Theme Development

    Often overlooked regarding anonymous functions. You can pass in variables from the outside scope quite easily with ‘use()’:

    $var = 'some string';
    add_filter( 'some_filter', function( $value ) use( $var ) {
         return $value . $var;
    }, 10, 1 );



    Robert, you are right that anonymous functions are very useful, especially when defining short filter or action handlers that use variables in the current scope (closures.)

    In this talk, I tried to avoid using PHP features that are newer than the minimum version of PHP required by WordPress, which is 5.2.4. Since closures / anonymous functions are a PHP 5.3-ism, I didn’t want to encourage their usage and then have developers mystified at why their code breaks on a host that only supports PHP 5.2.

    Thanks for your input!

    Hi Ben,

    Your presentation made me change the way I used to code WordPress Theme.
    My theme (Customizr) is built upon the OOP principles you describes.

    Thanks for those awesome slides!
    PS : I credit you in my functions.php file
