Your code is incorrect in some subtle ways but to get why we first need to get back to what is a nonce in wordpress and what does it protect against. A Nonce by the common definition is a number used only once and it is meant to fight replay attacks. In a replay attack … Read more
So, after doing some more digging, I answered my own question by “connecting the dots”, so to speak. There’s a lot of bits and pieces of info on this topic on StackOverflow and StackExchange, but none of them really answered my question. So here is the full working code to loading a wp_editor instance with … Read more
There is a bug in WordPress 4.8.2 which causes pending customized changes to not be injected into Ajax requests in the preview. This has been fixed in 4.9-alpha via #42162. In the mean time, however, you can do a workaround to modify the requested url with logic like: // Workaround defect introduced in WordPress 4.8.2 … Read more
A few things that I see: There’s a space in your first add_action declaration. Should be add_action(‘wp_ajax_wppl_function’, ‘wppl_function’); Have you declared wppl_function to run it? Have you localized your scripts when logged in? Please review the codex entry on wp_ajax_nopriv (action)

I skimmed through the plugin’s code and you could try to use the define_public_hooks() method of the Plugin_Name class to register your ajax action callbacks of the Plugin_Name_Public class: /** * Register all of the hooks related to the public-facing functionality * of the plugin. * * @since 1.0.0 * @access private */ private function … Read more
Testing is the only way to be sure, but my guess would be that it is not the query itself that is slowing the page load. After you have fetched those 2000 records, you are looping through them. Every time you call get_template_part. This function in turn calls locate_template, which leads to load_template, where you … Read more
All the WordPress AJAX calls should be handled by the admin-ajax.php, wether they happen on the frontend or in the backend. To grant the access you have to register the callbackfuntion for the AJAX call add those lines to your file: add_action( ‘wp_ajax_prefix_update_post’, ‘prefix_update_post’ ); add_action( ‘wp_ajax_nopriv_prefix_update_post’, ‘prefix_update_post’ ); Be sure to add some validation … Read more
It only redirects when accessed directly, as do all files located in wp-admin/. AJAX requests should work fine regardless of authentication status. Edit: wp-admin/admin-ajax.php should not redirect in any situation. Perhaps a plugin is redirecting all unauthenticated users to the homepage?
