Change widgets.php

Hi there,
what are you trying to achieve exactly?
Even if you manage to have different widgets appear to different users in the back-end, how would that work in the front end? What would a non-logged in user see?

Hello,

The page is for only logged-in users. So i don’t have the problem with the non-logged in users.

I like the drag & drop method to edit the Widgets. So i thought i could use it for my purpose.

On the front end:
dynamic_sidebar( $current_user->ID.’-homescreen-widgets’ );

My thoughts:
I create for each user a sidebar with the Sidebar-ID: [userID]-homescreen-widgets

So each user only sees his own Sidebar.

Now my problem is, that on the widgets.php site, will be shown all Sidebars. But I want that it show only the one for the user.

The only solution I can think of this, is saving a different copy of $sidebars_widgets in each user’s meta, and overwriting the global one depending on who is logged in.

I’d go about it like this. I assume all requests are from logged in users, so I’ll not add any is_user_logged_in() checks.

This would go on your functions.php or similar:

// Registed a sidebar for the user.
add_action( 'widgets_init', 'my_widgets_init' );
function my_widgets_init() {
	register_sidebar( array(
		'name'          => 'Sidebar Name',
		'id'            => get_current_user_id() . '-homescreen-widgets',
		'description'   => 'Place here the widgets that you want to display on your homescreen.',
		'before_widget' => '<aside id="%1$s" class="%2$s widget group">',
		'after_widget'  => '</aside>',
		'before_title'  => '<h3 class="widget-title">',
		'after_title'   => '</h3>'
	) );
}

// This fires whenever sidebars_widgets gets updated.
add_action( 'updated_option', 'my_updated_option' );
function my_updated_option( $option ) {
	if( 'sidebars_widgets' == $option ) {
		update_user_meta( get_current_user_id(), 'sidebars_widgets', wp_get_sidebars_widgets() );
	}
}

// Overwrite the array for all wp_get_sidebars_widgets() calls.
add_filter('sidebars_widgets', 'my_sidebars_widgets');
function my_sidebars_widgets($sidebars_widgets) {
	$sidebars_widgets = get_user_meta(get_current_user_id(), 'sidebars_widgets');
	return $sidebars_widgets;
}

And in your frontpage template:
dynamic_sidebar( get_current_user_id() . '-homescreen-widgets' );

Hope this helps.

Thank you very much for your help!

I don’t know why… but the widgets don’t get saved. I tried to change the code and debug. But I don’t know why it’s not working.

For what is the overwrite function?

Thanks a lot,
Francesco

Try changing:

// This fires whenever sidebars_widgets gets updated.
add_action( 'updated_option', 'my_updated_option' );
function my_updated_option( $option ) {
	if( 'sidebars_widgets' == $option ) {
		update_user_meta( get_current_user_id(), 'sidebars_widgets', wp_get_sidebars_widgets() );
	}
}

to:

// This fires whenever sidebars_widgets gets updated.
add_action( 'updated_option', 'my_updated_option', 10, 3 );
function my_updated_option( $option, $old_value, $value ) {
	if( 'sidebars_widgets' == $option ) {
		update_user_meta( get_current_user_id(), 'sidebars_widgets', $value );
	}
}

unfortunately it isn’t working. I added the PHP errors:

Is there a documentation to lookup how the widget get saved in the DB?

PHP Errors:
Illegal offset type in isset or empty – wp-includes/widgets.php:1483 – retrieve_widgets()
Illegal offset type – wp-includes/widgets.php:1151 – is_active_widget()
wp_list_widgets()

Thanks for your help!
