Why can't hook into wp_ajax_image-editor action?

    Dear WordPress community,
    please, does anybody know why the following code does not work? It should output Hello world when loading image editor with AJAX, but does nothing.

    function say_hello()
{
	var_dump("Hello world");
}
add_action( 'wp_ajax_image-editor', 'say_hello' );

    Is there something I’m missing?

    Thank you a lot,
    Jiri Hon

    I can’t comment on using that action, I’m unfamiliar with it. Your code is flawed though, var_dump() only works when passed a variable, it doesn’t work on static strings. Either assign the string to a variable which is in turn dumped, or simply use echo or printf(), like so:
    echo 'Hello World';

    I admit that this somewhat weird use case of var_dump, but it actually works also on literals.

    Please, is anybody experiencing the same problem with wp_ajax_image-editor hook? At least one another user noticed the same issue – I found this comment in Arlima plugin source code:

    // The following action is not possible to hook into wtf???
// add_action('wp_ajax_image-editor', array($this, removeImageVersions'));

    Resolved. The default hook for wp_ajax_image-editor action executes wp_die() so nothing can be done after the default hook, indeed it has high priority. The solution is to define the custom hook with higher priority.
