First of all let’s say that regarding these functions what is valid for styles is exactly valid for scripts, but there are some exceptions to the contrary explained in the answer. Main difference between wp_enqueue_* and respective wp_register_* functions, is that the first adds scripts/styles to the queue, the second prepares scripts/styles to be added. … Read more
You just need to add the styles directly to the page head. The best way to do this is to use the ‘wp_head’ action hook, assuming you are using a theme that has the hook. Like so: add_action(‘wp_head’, ‘my_custom_styles’, 100); function my_custom_styles() { echo “<style>*{color: red}</style>”; } Check out the WP codex to learn more … Read more
If you plan to do a lot of WP development you should bookmark this page: http://codex.wordpress.org/Conditional_Tags The other answer works but the conditional relies upon your page slug (myurl.com/this-is-the-slug) never changing. A more reliable method (IMO), and one that fits this case, would be to use the is_page_template(‘example-template.php’) conditional check instead.
There is a function called wp_script_is( $handle, $list ). $list can be one of: ‘registered’ — was registered through wp_register_script() ‘queue’ — was enqueued through wp_enqueue_script() ‘done’ — has been printed ‘to_do’ — will be printed Ditto all that for wp_style_is().
I want to use @import instead so I can override styles more easily Simply. Don’t. Do. That. You simply jump into the same hook and then deregister/dequeue the styles/scripts and throw in your custom ones. function PREFIX_remove_scripts() { wp_dequeue_style( ‘screen’ ); wp_deregister_style( ‘screen’ ); wp_dequeue_script( ‘site’ ); wp_deregister_script( ‘site’ ); // Now register your styles … Read more
Based on my own experience, I’ve used a combination of method 1 & 2 – the architecture and footer scripts of 1, and the ‘look-ahead’ technique of 2. For the look-ahead though, I use regex in place of stripos; personal preference, faster, and can check for ‘malformed’ shortcode; preg_match( ‘#\[ *shortcode([^\]])*\]#i’, $content ); If you’re … Read more
Why registering and queuing properly matters it should be in time – earlier than script/style is up for being output to page, otherwise it is too late; it should be conditional – otherwise you are loading stuff where you don’t need it and cause performance and functionality issues, for this you need WP environment loaded … Read more
add_menu_page and add_submenu_page both return the page’s “hook suffix”, which can be used to identify the page with certain hooks. As such, you can use that suffix in combination with the variable hooks admin_print_styles-{$hook_suffix} and admin_print_scripts-{$hook_suffix} to specifically target these pages. function my_menu() { $menu = add_menu_page( ‘Page 1’, ‘bar’, ‘something’, ‘else’, ‘foo’ ); $submenu … Read more
