So, i found the solution. Just add this code to theme’s functions.php file:
// this creates a widget shortcode functionality (use with [widget widget_name="WCAPF_Active_Filters_Widget"] shortcode)
function widget($atts) {
global $wp_widget_factory;
extract(shortcode_atts(array(
'widget_name' => FALSE
), $atts));
$widget_name = wp_specialchars($widget_name);
if (!is_a($wp_widget_factory->widgets[$widget_name], 'WP_Widget')):
$wp_class = 'WP_Widget_'.ucwords(strtolower($class));
if (!is_a($wp_widget_factory->widgets[$wp_class], 'WP_Widget')):
return '<p>'.sprintf(__("%s: Widget class not found. Make sure this widget exists and the class name is correct"),'<strong>'.$class.'</strong>').'</p>';
else:
$class = $wp_class;
endif;
endif;
ob_start();
the_widget($widget_name, $instance, array('widget_id'=>'arbitrary-instance-'.$id,
'before_widget' => '',
'after_widget' => '',
'before_title' => '',
'after_title' => ''
));
$output = ob_get_contents();
ob_end_clean();
return $output;
}
add_shortcode('widget','widget');
And after that we can use shortcodes like [widget widget_name=”WCAPF_Active_Filters_Widget”] or [widget widget_name=”WCAPF_Category_Filter_Widget”] or [widget widget_name=”WCAPF_Price_Filter_Widget”] in our pages.
