Show or hide a widget from pages

Question

I want to add a check option to the wordpress admin sidebar when I am writing a post or a page to display a specific widget. I tried display-widgets plugin but I want to be able to show a widget directly while writing the post.

Or is there is another way to do this it will be OK.

Answer 1

Barring the discovery of a plugin that does this already (I'm not aware of any that specifically do what you want) you'll need to create your own. add_meta_box and add_filter('widget_display_callback', $instance, $widget, $args) should be the bulk of what you need
