A custom sidebar for widgets

Hey all !

I’m working on a new theme, and I want to add a sidebar with placeable widgets.

I’ve seen a few tutorials, but nothing seems to work.

This is in my function.php:

function telescope_widgets_init() {
register_sidebar( array(
'name' => 'Sidebar Area 1',
'id' => 'sidebar-1',
'description' => 'Appears in the right-side sidebar area',
'before_widget' => '<aside>',
'after_widget' => '</aside>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );

register_sidebar( array(
'name' => 'Sidebar Area 2',
'id' => 'sidebar-2',
'description' => 'Appears in the right-side sidebar area',
'before_widget' => '<aside>',
'after_widget' => '</aside>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );

register_sidebar( array(
'name' => 'Sidebar Area 3',
'id' => 'sidebar-3',
'description' => 'Appears in the right-side sidebar area',
'before_widget' => '<aside>',
'after_widget' => '</aside>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );

register_sidebar( array(
'name' => 'Sidebar Area 4',
'id' => 'sidebar-4',
'description' => 'Appears in the right-side sidebar area',
'before_widget' => '<aside>',
'after_widget' => '</aside>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );

dynamic_sidebar( $sidebar );
$args = array(
	'name'          => sprintf( __( 'Sidebar %d' ), $i ),
	'id'            => "sidebar-$i",
	'description'   => '',
	'class'         => '',
	'before_widget' => '<li id="%1$s" class="widget %2$s">',
	'after_widget'  => "</li>\n",
	'before_title'  => '<h2 class="widgettitle">',
	'after_title'   => "</h2>\n",
);

}

add_action( 'widgets_init', 'telescope_widgets_init');

This is on my page.php, in the code. (Cuzz that will be showing on every page)

<?php get_header(); ?>

	<main role="main">
		<!-- section -->
		<section>

		<?php if (have_posts()): while (have_posts()) : the_post(); ?>

			<!-- article -->

			<div id="page-content"><div id="page-text">
			<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

				<?php the_content(); ?>

				<br class="clear">

				<?php edit_post_link(); ?>

			</article>
			</div>
			<div id="side-bar"></div>
			</div>
			<!-- /article -->

		<?php endwhile; ?>

		<?php else: ?>

			<!-- article -->
			<article>

				<h2><?php _e( 'Sorry, nothing to display.', 'html5blank' ); ?></h2>

			</article>
			<!-- /article -->

		<?php endif; ?>

		</section>
		<!-- /section -->
	</main>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

I got my widgets in the dashboard > widgets, but they just don’t show up.

Please help me on this one, it’s the final thing before the theme’s ready.

Thank you !
