If you don’t, WordPress has no idea your file exists. Once you understand how WordPress templates are loaded, you see get why it’s so important you load every single style and script this way. Why Every Single Style and Script Must Be Enqueued We’ll talk a bit more about that in the next section. Neglecting this process means that any theme or plugin that consolidates or reviews scripts will break because yours isn’t loaded using the expected WordPress method. These hooks all communicate together so that when wp_head() loads on the front end, your script is found and loaded with the others in the exact correct place.You hook your function into the wp_enqueue_scripts hook. You write a function which registers your scripts using the correct wp_enqueue script.The wp_enqueue() function is a hook in and of itself, which then hooks into wp_head() and wp_footer() as needed. It’s well worth learning more about how they work and where you can use them. While hooks are important for understanding wp_enqueue, they are also the secret ingredient for becoming a power WordPress developer. This is important to understand because WordPress is designed for every single CSS and JavaScript file to be loaded into the theme using these hooks. In other words, you can hook into either of these functions to enable specific unique code to show up on the correct pages of a WordPress website. If something needs to be loaded in the header of a page, it gets pulled (or hooked) in by wp_head(), and likewise for the footer by wp_footer(). They both look for any registered hooks within your plugins and themes. While the wp_footer() function must be present in footer.php: The wp_head() function must be present in header.php: There are two important functions that get loaded, one into header.php and the other into footer.php. This ensures your WordPress page will be correctly, and fully loaded.īringing all of this together are WordPress hooks. This way, the top containers with the logo and menu (as well as the bottom containers with any additional footer information) get repeated consistently for every page. While an individual post will load these files: For example, the home page is loaded like this: With few customized exceptions, both of these files will be loaded no matter what individual page templates get sandwiched between. The website offers a handy overview of the file hierarchy system.Ī primary aspect to understand is that each individual page template gets wrapped around the header.php and footer.php files. Whether you are writing a theme or a plugin, it is important to understand how any front-end loading scripts will be incorporated into the hierarchy. This has an impact on the way themes are loaded. Let’s start with the WordPress template hierarchy. Both work together to ultimately create a cohesive front end that is flexible and compatible with an unpredictable combination of themes and plugins. Hierarchies are driven by a set of special file names, while hooks can be referenced anywhere within a theme or plugin’s structure. Part of WordPress’ power is its ecosystem of hierarchies and hooks. Let’s get started! Introducing WordPress’ Template Structure In this article, you’ll learn exactly what wp_enqueue is all about, and how it can be used to improve your WordPress projects. This simple integration can prevent issues with your theme when used with other WordPress plugins. The wp_enqueue function is a great place to start. If you optimize your themes and plugins correctly, you can improve your site’s performance while enhancing user experience. In fact, overlooking inherent functions such as wp_enqueue could even impact your site’s overall effectiveness. While WordPress is powerful, there are plenty of under-the-hood features that can help you maximize its efficiency.
