How to Create Multiple instance of Widget ?

You need to implement your Widget using the Widgets API, so that WordPress knows how to make multiple instances of the Widget.

Your Widget declaration should take the following format:

class My_Widget extends WP_Widget {
    function My_Widget() {
        // widget actual processes
    }

    function form($instance) {
        // outputs the options form on admin
    }

    function update($new_instance, $old_instance) {
        // processes widget options to be saved
    }

    function widget($args, $instance) {
        // outputs the content of the widget
    }

}
register_widget('My_Widget');
