New plugin / theme editor wp_ajax_ save hook not working or inexistent

[cristianuibar]

Hello,

We are trying to use a hook using: ​https://developer.wordpress.org/reference/hooks/wp_ajax__requestaction/
for the new Code Editor in Plugins and Theme.

Add any of these hooks using add_action(), and they will not work.

Neighter
wp_ajax_edit_theme_plugin_file, nor
wp_ajax_edit-theme-plugin-file
works.

I expected the hooks to work and they didn't.

We tried an alternative using the 'wp_doing_ajax' hook, but it executes twice per request, even though we were checking for:

if (isset($_REQUEST['action']) && $_REQUEST['action'] == 'edit-theme-plugin-file')

Best,
Cristian Uibar

@cristianuibar Welcome to trac

How did you test it? Do you have a test example?

I think you need to use priority <= 1, because the default callback for the wp_ajax_edit-theme-plugin-file action has priority 1 and calls wp_send_json_success() (or wp_send_json_error()), that implicitly calls die().

Hi @cristianuibar

As @birgire alluded to, this is because your action is hooked later than when the core action runs, you'll need to hook in at priority 0 or lower: edit: I originally said 9, but that doesn't work, use 0 or -1 and it will work.

add_action( 'wp_ajax_edit-theme-plugin-file', function() {
	// Returns a failure for all edit attempts
	die( '-1' );
}, 0 );

I'm marking this as worksforme as the above code works as expected.

Indeed. It works with a lower priority. This should be stated as a NOTE in the docs maybe?
