WP Ajax runs both public as well as closed calls via admin.php. This means that you don’t have access to the whole wp environment, such as do_shortcode(), which is inside /wp-includes/shortcodes.php. This still can get worked around (and as well for oEmbed). See the following example that you could use in your AJAX callback to … Read more
First off, this is very borderline within the scope of WPSE, it at all. Apart from the shortcode to trigger the initial HTML output, this is really just AJAX. Anyhow, that being said, this is how it’s done: The PHP Assuming that the above PHP snippet you supplied is functional, place the following in a … Read more
If you do not die, execution will continue and might generate extra output which might break whatever information you are trying to send from the server to the browser. Strictly speaking, you might not need to die, but there is very little point in taking the risk. In more general terms, WordPress Ajax shows its … Read more
Uploading files in ajax is a bit tricky because it is not possible to upload files using the browser’s XMLHttpRequest object so you need to use some kind of Ajax upload plugin and the easiest one would be the the JQuery Form Plugin which makes things much easier and it’s included in WordPress. So to … Read more

Note that you are not calling the_post(), instead you are calling $posti->the_post(). Same logic … Read more
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
I have observed the same issue with contact-form-7 a while back. But note that registering shortcodes based on is_admin is doing_it_wrong (see gmazzap`s answer) There are the two reasons that seem legitimate at first sight (and why they are wrong): (Unlikely) The plugin author tried to optimize the script to only register shortcodes when they … 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
