wp_is_mobile() does not really solve your problem completely. To be honest here, there is no logic in WordPress to achieve what you want First of all, wp_is_mobile() only checks for mobile devices. Tablets are excluded from this Window sizes are determined on browser side, not server side, so there are no way for php to … Read more
Use wp_enqueue_script in your shortcode handler, in WordPress >= 3.3 it will be added to the page in the wp_footer action. Pass any data you need from PHP to JavaScript via wp_localize_script.
When and where to load styles & scripts 1) & 2) » If you are enqueueing scripts and styles, you will want to use one of these three hooks: « wp_enqueue_scripts (for the frontend) login_enqueue_scripts (for the login screen) admin_enqueue_scripts (for the admin dashboard) » Don’t let the names fool you — they are for … Read more
I am presuming you want to add this as resource hints on the HTML and not as an server push header. As preload is not supported by WP native wp_resource_hints function, you would need to create a custom function printing the preload tags and add somewhere in the beginning of head section of the HTML. … Read more
To circumvent this, you can use strpos() with the_posts hook, which gets fired before wp_head. But one of the drawbacks is that its an extra pass at the data. You’re essentially doing the same inside the callback you’re hooking onto wp_head, i don’t see the difference.. (please clarify if you think otherwise).. Whether you hook … Read more
I have not tested it, but could is_main_query() (appeared in 3.3) be used here to test that the query being run is the query used to populate ‘the Loop’. (I’m not sure how it handles new WP_Query instances, though). The Codex says that it can be used on the pre_get_posts, but looking at the code … Read more
Though WordPress already has a basic .js API (with register and enqueue script), I don’t see why you cannot use it in conjunction with require.js, at least at the modular level. From what I can tell (never used it) it only needs to be loaded, so you can, wp_enqueue_script( $handle, ‘…folder../require.js’, $deps, $ver, $in_footer ); … Read more
WordPress doesn’t really offer this functionality. You basically grab the array of enqueued scripts + styles and minify & concatenating them before they are output (using 3rd party script), of course you would want to cache this as well. This is quite complicated so I suggest instead: There are several plugins on wordpress.org that do … Read more
Yes you can. But to make sure the script has not already been registered or enqueued, use wp_script_is() as follows: foreach( $jquery_ui as $ui ) { if( !wp_script_is( $ui ) ) { wp_enqueue_script( $ui ); } } This will prevent conflicts due to another instance of the script being already enqueued.
I had a similar issue within WordPress a few days ago but it doesn’t really have anything to do with WordPress. Simply put, your code is loading the babel-polyfill library twice somehow. Most commonly it can happen if you’re using the library yourself and on top of that a third-party library is including that too. … Read more
