Keep header when switching theme

  • Hey

    Im trying to do a plugin that will keep the users header after theme change. So far i come up with this.

    <?php 

add_action('pre_update_option_theme_mods_' . get_option( 'stylesheet' ), save_header_image_as_option);
add_action('switch_theme', 'keep_header'); 

error_log("stylesheet " . get_option( 'stylesheet' ),0);
error_log("prevous header " . get_option( 'previous_header_image_saved' ),0);

function save_header_image_as_option()
{
	$details_before = get_theme_mods($blog_id);
	update_option("previous_header_image_saved", get_theme_mod('header_image'));
	error_log("before theme change" . json_encode($details_before), 0);
	return $details_before;
}

function keep_header()
{
	$details_after = get_theme_mods($blog_id);
	set_theme_mod('header_image', get_option("previous_header_image_saved"));
	error_log("after theme change" . json_encode($details_after), 0);
	return $details_after;
}

?>

    Sadly it does not work, because the trigger is also triggede when trying to CHANGE the header. Any suggestion on how to accomplish to keep header when changing themes ?

    Ended up with this:

    <?php
/**

add_action('pre_update_option_stylesheet', 'phi_pre_update_option_stylesheet');
add_action('switch_theme', 'phi_switch_theme');

function phi_pre_update_option_stylesheet($stylesheet)
{
        update_option('previous_header_image_saved', get_theme_mod('header_image'));

        return $stylesheet;
}

function phi_switch_theme()
{
        if (get_option('previous_header_image_saved')) {
                set_theme_mod('header_image', get_option('previous_header_image_saved'));
                delete_option('previous_header_image_saved');
        }
}
?>
