Using wp_die() is the best of those options. As others have noted, there are many reasons to prefer a WordPress-specific function over the plain die or exit: It allows other plugins to hook into the actions called by wp_die(). It allows a special handler for exiting to be used based on context (the behavior of … Read more
I think the only thing missing here is that you need to move add_action(‘wp_ajax_nopriv_ajaxlogin’,’ajax_login’); outside ajax_login_init. That code registers your Ajax handler, but when you only run it on wp_enqueue_scripts, it’s already too late and wp_ajax_nopriv_ hooks are already run. So, have you tried something like this: function ajax_login_init(){ if ( ! is_user_logged_in() || ! … Read more
admin-ajax.php loads wp-load.php: /** Load WordPress Bootstrap */ require_once( dirname( dirname( __FILE__ ) ) . ‘/wp-load.php’ ); wp-load.php loads wp-config.php, and there wp-settings.php is loaded. And here we find this: // Load the functions for the active theme, for both parent and child theme if applicable. if ( ! defined( ‘WP_INSTALLING’ ) || ‘wp-activate.php’ === … Read more

Example: if ( is_admin() && defined( ‘DOING_AJAX’ ) && DOING_AJAX ) { // do something } I have asked … Read more
In backend there is global ajaxurl variable defined by WordPress itself. This variable is not created by WP in frontend. It means that if you want to use AJAX calls in frontend, then you have to define such variable by yourself. Good way to do this is to use wp_localize_script. Let’s assume your AJAX calls … Read more
A 0 response means either that the action is not set (in the ajax data) or that the action’s callback function cannot be found.
the “safer and cleaner” way would be to use admin-ajax.php that comes with wordpress and wp_ajax hook to call your processing function from your plugin file and use wp-nonce to check the integrity of the call. for example: your ajax JQuery call would be <script type=”text/javascript” > jQuery(document).ready(function($) { var data = { action: ‘ACTION_NAME’, … Read more
Yep, this is nasty issue that to have full WordPress environment you need to spend considerable time loading it. I’ve needed much better performance (for very dynamic incremental search feature) for work and what I went with is: Custom file as Ajax handler. SHORTINIT constant for limited WP core load. Very selectively loaded parts of … Read more
