Get sidebar parameters (before_widget, before_title, etc.) from within a widget

Question

Is it possible to dynamically get sidebar parameters from within a widget? That is, I am trying to access the before_widget/after_widget/before_title/after_title/name parameters of the containing sidebar.

Suppose we have a sidebar registered like so:

register_sidebar( array(
    'name' => "Homepage Sidebar",
    'id' => 'homepage-sidebar',
    'before_widget' => '<div id="%1$s" class="widget-container %2$s">',
    'after_widget' => '</div>',
    'before_title' => '<h2 class="widget-title">',
    'after_title' => '</h2>',
) );

How would I access those values from inside my widget's widget() function? Like, how would I do something like this:

public function widget( $args, $instance ) {
    // outputs the content of the widget
    if ($someCondition)
        echo $sidebar->before_title . 'My widget title' . $sidebar->before_title;
    echo 'You are looking at ' . $sidebar->name;
}

Is this possible?

Answer 1

The parameters are given (as an array) as the first argument provided to the widget method. The second argument, $instance, holds the options for that particular instance of the widget.

My usual set up is:

 function widget($args, $instance){
    //Extract the widget-sidebar parameters from array
    extract($args, EXTR_SKIP);

    echo $before_widget;
    echo $before_title;
    //Display title as stored in this instance of the widget
    echo esc_html($instance['title']); 
    echo $after_title;
    //Widget content
    echo $after_widget;

 }

Use variable name only, like:

$name
$before_title
$after_title
$before_widget
$after_widget
