As of WordPress 3.4, calls to wp_enqueue_script() can be made inline. So, it is perfectly acceptable to call it where needed, such as inside a shortcode callback, or conditionally based upon returned queries, as you’ve done here.
Why do you need it in the header? It’s enqueuing in the footer because when it was registered it was set to enqueue in the footer. In wp-includes/script-loader.php: $scripts->add( ‘jquery-ui-core’, ‘/wp-includes/js/jquery/ui.core.js’, array(‘jquery’), ‘1.8.12’ ); $scripts->add_data( ‘jquery-ui-core’, ‘group’, 1 ); The second line forces it to load in the footer. You could deregister the script, then … Read more
The problem is that the wp_enqueue_style() call is inside of the category_collapse() member function of the CategoryCollapse() class, and the CategoryCollapse() class is being instantiated by a callback hooked into the plugins_loaded action hook. That means that the wp_enqueue_style() function is attempting to execute at the plugins_loaded hook, which fires before init, wp_enqueue_scripts, and admin_enqueue_scripts. … Read more
You can use action hook and enqueue script and style to the site. function my_scripts() { wp_enqueue_style(‘bootstrap4’, ‘https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css’); wp_enqueue_script( ‘boot1′,’https://code.jquery.com/jquery-3.3.1.slim.min.js’, array( ‘jquery’ ),”,true ); wp_enqueue_script( ‘boot2′,’https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js’, array( ‘jquery’ ),”,true ); wp_enqueue_script( ‘boot3′,’https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js’, array( ‘jquery’ ),”,true ); } add_action( ‘wp_enqueue_scripts’, ‘my_scripts’ ); If you want to add the scripts after jQuery then you can use the … Read more
The tricky thing is knowing whether or not a particular script or style was enqueued by the theme. Themes and plugins both use the same hooks and functions, so they’re not explicitly labelled in any way as belonging to a specific theme or plugin. This means that the only way to know whether a script … Read more
Note: the file name is functions.php, not function.php (but that’s probably just a typo in the question). To remove a script or style, you must remove it after it was added. If you try to remove it before it was added, or even print $GLOBALS[‘wp_scripts’]->registered, nothing will happen, since it was not added yet. So … Read more
Inside admin-header.php, there’s the following set of hooks: do_action(‘admin_enqueue_scripts’, $hook_suffix); do_action(“admin_print_styles-$hook_suffix”); do_action(‘admin_print_styles’); do_action(“admin_print_scripts-$hook_suffix”); do_action(‘admin_print_scripts’); do_action(“admin_head-$hook_suffix”); do_action(‘admin_head’); The one to always use it admin_enqueue_scripts, both for stylesheet and scripts. More info in this answer. It has one additional argument, the $hook_suffix. This argument is exactly the same as the return value that you get from add_submenu_page() … Read more
You can’t — URLs must have a protocol for WordPress to enqueue them. What you can do, though, is detect which protocol to use and then use that. $protocol = is_ssl() ? ‘https’ : ‘http’; $url = “$protocol://example.com/resource”; But for enqueuing scripts from your theme, you should use get_template_directory_uri() or get_stylesheet_directory_uri() which already handle SSL: … Read more
You could try using the style_loader_tag filter. add_action(‘wp_enqueue_scripts’, ‘my_enqueue_scripts’); function my_enqueue_scripts() { wp_enqueue_style(‘my-style-handle’, “https://wordpress.stackexchange.com/fonts/custom-font-folder/CustomFontFile.woff2”, array(), null); } add_filter(‘style_loader_tag’, ‘my_style_loader_tag_filter’, 10, 2); function my_style_loader_tag_filter($html, $handle) { if ($handle === ‘my-style-handle’) { return str_replace(“rel=”stylesheet””, “rel=”preload” as=”font” type=”font/woff2″ crossorigin=’anonymous'”, $html); } return $html; } Here we’re enqueuing the stylesheet using the normal wp_enqueue_style function. We then capture the … Read more
init is much earlier than page template loading and not appropriate place for enqueues (despite many tutorials and docs using it for that). Hook your function to wp_enqueue_scripts and make sure you are doing that hooking before wp_head() call in template.
