![]() ![]() Tap into WordPress’ system for managing myriad scripts and styles.ObjectivesĪt the end of this lesson, you will be able to: In this lesson, we will be customizing a theme, but what you will learn is also applicable to building plugins. Note: The method for adding scripts and styles to WordPress is essentially the same for both plugins and themes. For this lesson, the goal is to simply become familiar with enqueueing so you can complete it in its most basic form. Additional and deeper PHP learning is beyond the lesson’s scope so we encourage you to look at other resources such as the official PHP manual. Don’t worry about being fluent in PHP programming the information you need for this lesson is provided. ![]() Enqueueing is used for both scripts and styles and means we must access and alter the functions.php file that comes with your WordPress installation. The method for adding your own scripts and styles to your theme is called enqueueing. WordPress has built-in systems to keep track of all the scripts and styles, keep them from conflicting with each other, and use them in the correct order. Many scripts and styles are included in WordPress core others are added by plugins or themes. At its core, WordPress already manages a long list of scripts and styles to produce a functioning web page. The server-side language PHP does the heavy lifting behind the scenes to provide data to the browser. Client-side languages like HTML, CSS, JavaScript and jQuery produce a rich and seemingly limitless user experience. Sometimes it may still be necessary to add a script inline though.WordPress relies on several programming languages to provide a solid, yet extensible, framework to build upon. ![]() Data can be made available to the script using wp_localize_script(). js file and enqueued using wp_enqueue_script() on the wp_enqueue_scripts hook. Generally, JavaScript should be added to a. Instead of creating a fake dependency file (and undesirable additional HTTP request), use wp_head or wp_footer to output the inline script: add_action( 'wp_head', 'wpse_add_inline_script' ) Since there is no dependency in this case, wp_add_inline_script() is not the right tool for the job. By design, print_inline_script() requires a valid dependency, $handle. When using wp_add_inline_script(), WP_Scripts::print_inline_script() will ultimately be used to output inline scripts. Update: WordPress added support for adding inline scripts and styles without a dependency in v5.0. ![]() The 'before' value prints it above 'after'. The default of $position input argument in wp_add_inline_script() is 'after'. Wp_add_inline_script( 'dummy-handle-footer', 'console.log( "footer" ) ' ) Wp_enqueue_script( 'dummy-handle-footer' ) To display it in the footer: wp_register_script( 'dummy-handle-footer', '',, '', true ) That will display the following in the header, i.e.between the. Wp_add_inline_script( 'dummy-handle-header', 'console.log( "header" ) ' ) Wp_enqueue_script( 'dummy-handle-header' ) wp_add_inline_script() - without dependencyĪccording to ticket #43565, similar will be supported for wp_add_inline_script() in version 4.9.9 5.0 (thanks to and for the verification in comments): wp_register_script( 'dummy-handle-header', '' ) Where we would hook this into the wp_enqueue_scripts action. Wp_add_inline_style( 'dummy-handle', '* ' ) Here's an example from wp_register_style( 'dummy-handle', false ) The wp_add_inline_style() can be used without a source file dependency.
