I started a small WordPress plugin and tried to orientate myself a little bit towards the Speaking Plugin<\/a> of Alain Schlesser<\/a> for the structure and basic principles. So I came about the topic autoloading. Alain wrote a custom autoloader for the plugin but mentioned the possibility via composer in his talk at the WordCamp Nijmegen<\/a>. This post describes how to create an autoloader with Composer<\/a>.<\/p>\n\n\n\n\n\n\n\n

Of course, you need Composer installed. Now we run composer init<\/code> in our project folder and enter a few information \u2013 as a result, we get a composer.json<\/code>.<\/p>\n\n\n\n

After that, we need to add a small additional piece into the composer.json<\/code>, so we can create the autoloader in the next step. This section looks like that in my plugin (helpful for the whole autoloading thing with Composer was an article from phpenthusiast.com<\/a>):<\/p>\n\n\n

\"autoload\"<\/span>: {\n  \"psr-4\"<\/span>: {\n    \"FlorianBrinkmann\\\\CustomizeThemesInstaller\\\\\"<\/span>: \"src\/\"<\/span>\n  }\n}<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
We map the namespace FlorianBrinkmann\\CustomizeThemesInstaller<\/code> to the src<\/code> directory, so that, for example, the class FlorianBrinkmann\\CustomizeThemesInstaller\\Plugin<\/code> is searched in the file src\/Plugin.php<\/code> (PSR-4 requires the usage of namespaces).<\/p>\n\n\n\n
Now we run composer dump-autoload<\/code> to create the autoloader and include it into our bootstrap file via require_once __DIR__ . '\/vendor\/autoload.php';<\/code>.<\/p>\n\n\n\n

For the production, it is recommended to optimize the autoloader, so it does not need to scan the file system before resolving a class name. There are different ways to optimize it, as described in the Composer docs<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
