how to make plugin settings same for all sub site

Hmm. You might have to do some hacking of the actual plugins source code. I’ll look around as well I might have a need for such a feature.

Hardcoding your default settings into the plugin, editing the settings page to make your settings read-only – all useful tricks for sure. No magic though.

For example here’s some typical options set at the top of some awesome plugin:

//	$myawsomeoption = get_option( 'myawsomeoption' );
	$myawsomeoption = 'unchanging value of my option instead';

Maybe later in the plugin you want to show the setting input, but you can make the text area read-only:

<td class="myawsomeoption-style"><textarea readonly="readonly" name="{$myawsomeoption}">{$myawsomeoption}</textarea></td>

Alternatively, you can make the settings page appear only to a superadmin, then visit each blog to input your universal settings:

add_submenu_page(‘settings.php’, ‘My Awesome Plugin’, ‘My Awesome Plugin’, ‘manage_network‘, ‘myawesomeplugin’, ‘myawesomeplugin_page’);

thanks David
i will try that
i could also try making my own plugin that would disable the settings for other plugins
i wish there was a plugin like that…
back to work then…

did a workaround
created my own plugin which hides the links in the admin bar and in the admin sidebar for non super admin
like:

function remove_wp_nodes() {
	global $wp_admin_bar;
if(((!is_super_admin()) || ($user->ID != 0)) || (!is_admin_bar_showing())) {
	$wp_admin_bar->remove_menu('wp-logo');          // Remove the WordPress logo
}
}add_action( 'admin_bar_menu', 'remove_wp_nodes', 999 );

then used

whew…
moving on…
