On this page: http://codex.wordpress.org/Function_Reference/wp_add_dashboard_widget
The function wp_add_dashboard_widget is described.
It states:
wp_add_dashboard_widget($widget_id, $widget_name, $callback, $control_callback = null)
How do you use the $control_callback, properly? I am completeley stuck, as I have defined it but cannot use it.
I need to create a form within this widget which is why I am using the control_callback.
EDIT: as a side note I am using WordPress 3 and Multisite
Solution : hover on the title bar of your widget, then click configure
Don’t ask me why this works like this but it does.
Do you need to handle form/input data? If not, then you can omit the
$control_Callback, and simply use the$callbackin order to display content.
