The best way to do this is to use wp_localize_script(), it serves exactly the purpose you are mentioning: passing strings to Javascript from PHP. You can do all sorts of interesting things with that: as a rule of thumb, use that when you want PHP to communicate with Javascript. In your case you want something … Read more
If it is called by shortcode, then the shortcodes are fired before the page loads (which is why you never echo in a shortcode) – you could cut out the existing call to the enqueue, and add it to the shortcode function at the top. If not, then as RRikesh suggests, you could wrap the … Read more
By the time your widget (or sidebar if this is hard-coded) loads you have already missed the wp_enqueue_scripts hook, which runs in the header and that means that you have missed the window for registering the script in the <head> at all, which you are trying to do– there is no fifth parameter that would … Read more
This is how you should do this: function my_scripts_method() { wp_enqueue_script( ‘pikachoose’, // this is your custom name for this JS lib get_stylesheet_directory_uri() . ‘/js/pikachoose/jquery.pikachoose.min.js’, // this is the url address of it’s file (let’s say you put it in your theme directory under /js/pikachoose/ directory array( ‘jquery’ ) // it depends on jquery ); … Read more
Whatever is hooked to activation runs in just a single request when the plugin is activated in a sandbox, and the output is captured to check for errors. Your code won’t run on any subsequent request after that single activation, so your script will not be registered. It works on init because that action runs … Read more
Make sure you are also including the jquery effects core… and jquery if it’s not already being loaded. function my_callback() { wp_enqueue_script(‘jquery’); // If not already loaded wp_enqueue_script(‘jquery-effects-core’); wp_enqueue_script(‘jquery-effects-shake’); } add_action(‘wp_enqueue_scripts’, ‘my_callback’);
Since 4.5 there is a function that lets you append inline js to an enqueued js file, it is called wp_add_inline_script. Now, this function does not let you add any js code that has a </script> in it for security reasons. But when you look at the wp_add_inline_script source code, you can see that it … Read more
The simplest and most-common cause for this issue is that you have failed to fire wp_footer() immediately before the closing </body> tag in your footer.php file: <?php wp_footer(); ?> </body>
Currently (WP 4.6) WordPress includes jquery 1.12.4, so as @toscho notes there are no compatibility issues with older IE browsers. However, it was recently announced that 1.12.4 will be the last jquery version of that branch. Sooner or later WP will have to move to jquery 3.0 branch, in which all support for IE 6-8 … Read more
the_header() does not even seem to be native WP function? Technically getting header isn’t what really causes styles and scripts to load, it’s wp_head() call that should be made there (and wp_footer() call in footer).
