This example widget code, place the code in separate file, then include it in finctions.php like that:
require( get_template_directory() . '/menu-widget.php' );
Register the widget(match the class names!)-
function register_my_widget() {
register_widget( 'example_widget' );
}
And call the widget:
add_action( 'widgets_init', function(){
register_widget( 'My_Widget' );
});
And here it comes the widget code:
<?php
/**
* Example Widget Class
*/
class example_widget extends WP_Widget {
/** constructor -- name this the same as the class above */
function example_widget() {
parent::WP_Widget(false, $name = 'Example Text Widget');
}
/** @see WP_Widget::widget -- do not rename this */
function widget($args, $instance) {
extract( $args );
$title = apply_filters('widget_title', $instance['title']);
$message = $instance['message'];
?>
<?php echo $before_widget; ?>
<?php if ( $title )
echo $before_title . $title . $after_title; ?>
<ul>
<li><?php echo $message; ?></li>
</ul>
<?php echo $after_widget; ?>
<?php
}
/** @see WP_Widget::update -- do not rename this */
function update($new_instance, $old_instance) {
$instance = $old_instance;
$instance['title'] = strip_tags($new_instance['title']);
$instance['message'] = strip_tags($new_instance['message']);
return $instance;
}
/** @see WP_Widget::form -- do not rename this */
function form($instance) {
$title = esc_attr($instance['title']);
$message = esc_attr($instance['message']);
?>
<p>
<label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title:'); ?></label>
<input class="widefat" id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo $title; ?>" />
</p>
<p>
<label for="<?php echo $this->get_field_id('message'); ?>"><?php _e('Simple Message'); ?></label>
<input class="widefat" id="<?php echo $this->get_field_id('message'); ?>" name="<?php echo $this->get_field_name('message'); ?>" type="text" value="<?php echo $message; ?>" />
</p>
<?php
}
} // end class example_widget
add_action('widgets_init', create_function('', 'return register_widget("example_widget");'));
?>
