action switch_theme, after_switch_theme should not be trigged when switch_theme for child site.

If you hook to after_switch_theme ( on network's theme ) for initialize some default values, then your switch theme for child site by this line :

switch_to_blog( $child_site_Id );
switch_theme( $new_theme_name );
restore_current_blog();

The hook after_switch_theme will be trigger on network's theme.
I think it is incorrect.

Hi @nguyenvanduocit, thanks for the report. I'm not able to reproduce the described issue.

I did the following in a multisite setup where the same theme was activated for 2 sites.

In mu-plugins/index.php, I added a hook to switch the site and then switch that site's theme:

add_action( 'after_setup_theme', 'test_33835', 999 );
function test_33835() {
	switch_to_blog( 2 );
	switch_theme( 'theme-two' );
	restore_current_blog();
}

In theme-one, the theme that was activated on all sites, including the network, I added:

add_action( 'after_switch_theme', 'theme_one_after_switch_theme' );
function theme_one_after_switch_theme() {
	die( 'Theme Two' );
}

And in theme-two, the theme I was switching to:

add_action( 'after_switch_theme', 'theme_two_after_switch_theme' );
function theme_two_after_switch_theme() {
	die( 'Theme Two' );
}

I loaded foo.bar/wp-admin/network/sites.php to trigger the initial mu-plugins action and then *removed* the action from mu-plugins/index.php so that it would not trigger on the next page view.

I then loaded the front page of site 2, which now had theme-two activated and was shown "Theme-Two".

If I redo the experiment with Theme Two as a child of Theme One, and used echo instead of die, I see that both the child theme and the parent theme will fire as expected.

Are you getting different results than this? If so, can you describe steps to reproduce?

I'm going to close this out. Please re-open with steps to reproduce if necessary.
