I’ve tested your code and it works perfectly. I’ve just declared the dependencies for the JavaScript, so it is loaded correctly after jQuery. This is how I’ve tested it: functions.php function my_resource() { wp_enqueue_script(‘my-jquery’,get_template_directory_uri().’/jqfunctions.js’, array(‘jquery’)); wp_localize_script( ‘my-jquery’, ‘myback’, array(‘ajax_url’ => admin_url( ‘admin-ajax.php’ ))); } add_action(‘wp_enqueue_scripts’, ‘my_resource’); function getsomething(){ wp_send_json_error(‘hey’); } add_action(‘wp_ajax_nopriv_getsomething’, ‘getsomething’); add_action(‘wp_ajax_getsomething’, ‘getsomething’); jqfunctions.js … Read more
The correct answer is to just do AJAX the right way.

Transients should be used for short (for varying definition of it) time caching, and they are by design not reliable. From your description it sound like you are using them in a manner they were not designed to support and therefor probably the “best” for you is to not use transients at all.
This is a simple example of rendering some items on the front-end that use AJAX to trigger changes in the back-end and update the UI from that response. There are other examples that enqueue scripts so just read up on AJAX and consider this a high level view. REGISTER AJAX/SCRIPTS/CSS add_action(‘init’, function () { // … Read more
In WP REST API v2 use the permission_callback found in the Adding Custom Endpoints Docs. <?php add_action( ‘rest_api_init’, function () { register_rest_route( ‘myplugin/v2’, ‘/author/(?P<id>\d+)’, array( ‘methods’ => ‘GET’, ‘callback’ => ‘my_awesome_func’, ‘args’ => array( ‘id’ => array( ‘validate_callback’ => ‘is_numeric’ ), ), ‘permission_callback’ => function (WP_REST_Request $request) { if ( current_user_can( ‘edit_others_posts’ ) ) { … Read more
To clarify your doubt you localized variable will contains the same values until it is overriden. In your case EMX.ajaxurl will be available throught the script. Ajax not happening at your intended event might be due to not executing the ajax function but definetly not due to EMX.ajaxurl. EMX.ajaxurl will contain the ajax url. EMX.ajaxurl … Read more
You need to allow AJAX requests for guests too. Usually when a WordPress AJAX call returns 0, it means that there are no capabilities for the user to perform that action. Also, your debug info showed Guest. Alter your function to include the nopriv AJAX for guests: add_action(‘wp_ajax_nopriv_fahadsending_mail’, ‘fahadsending_mail’); add_action(‘wp_ajax_fahadsending_mail’, ‘fahadsending_mail’); function fahadsending_mail(){ $to = … Read more
