Ajax in WordPress works by sending an HTTP post to /wp-admin/admin-ajax.php (by default) that then fires the corresponding hook. So, you attach some jquery to an event triggered by your delete button, which then posts to admin-ajax.php, which has an action, say, delete_my_options(), which actually runs the php to delete. Then, you have a function, … Read more
Edit: I’ve kept my original answer below, however, I’m not sure what I was thinking… You should never need to trigger do_action( ‘wp_ajax…’ ). While I can’t be sure what the issue is, is the code in the question is roughly ok (I think $_POST should be $_GET with .getJSON). Try putting this at the … Read more
This will do the trick when added to your functions file: if (!is_admin()) add_action(“wp_enqueue_scripts”, “my_jquery_enqueue”, 11); function my_jquery_enqueue() { wp_deregister_script(‘jquery’); wp_register_script(‘jquery’, “//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js”, false, null); wp_enqueue_script(‘jquery’); }
Ajax Handler It is indeed a bit confusing that the Ajax handler is in the wp-admin/ directory, but yes, you can and should use it for non-admin requests too. You then register a handler for the wp_ajax_nopriv_[action] hook, instead of the normal wp_ajax_[action]. In this case you only have to follow the first lines of … Read more
You have a typo in your code. It should be: function load_my_script(){ wp_register_script( ‘my_script’, get_template_directory_uri() . ‘/js/myscript.js’, array( ‘jquery’ ) ); wp_enqueue_script( ‘my_script’ ); } add_action(‘wp_enqueue_scripts’, ‘load_my_script’); The jQuery dependency needs to be an array(), not just a string. This will force your script to load after jQuery.
Yes, jQuery is part of WordPress core. But–it can become outdated, because jQuery updates can happen in between WP releases. The recent release of WordPress does use a very recent version of jQuery. By default, wp_enqueue_script(‘jquery’) grabs jQuery from the core at /wp-includes/js/jquery/jquery.js. The “correct” way to add jQuery to your WP site is: function … Read more
To get you started, the basic functions and overrides as far as I know currently.There might be better solutions, but I only had two days with 3.5 yet: // open modal – bind this to your button if ( typeof wp !== ‘undefined’ && wp.media && wp.media.editor ) wp.media.editor.open( ##unique_id_here## ); // backup of original … Read more
Brady is correct that the best way to handle saving and displaying of custom post type orders is by using the menu_order property Here’s the jquery to make the list sortable and to pass the data via ajax to wordpress: jQuery(document).ready(function($) { var itemList = $(‘#sortable’); itemList.sortable({ update: function(event, ui) { $(‘#loading-animation’).show(); // Show the … Read more
Here’s a working example: add_action( ‘wp_enqueue_scripts’, ‘menu_scripts’ ); function menu_scripts() { wp_enqueue_script( ‘responsive-menu’, get_bloginfo( ‘stylesheet_directory’ ) . ‘/js/responsive-menu.js’, array( ‘jquery’ ), ‘1.0.0’ ); wp_enqueue_script( ‘custom-script’, get_stylesheet_directory_uri() . ‘/js/custom_script.js’, array( ‘jquery’ ) ); } Or like this which apparently loads faster: function my_scripts_method() { wp_enqueue_script( ‘custom-script’, get_stylesheet_directory_uri() . ‘/js/custom_script.js’, array( ‘jquery’ ) ); } add_action( ‘wp_enqueue_scripts’, … Read more
In case you want to know if the user is logged in at the current moment. The other answers check if the user is logged in or not when the page loaded not the time when you’re running the javascript. The user could have logged in in a seperate tab for instance Put this in … Read more
