Register Custom Widget Areas in WordPress

Register Custom Widget Areas in WordPress

Create custom widget areas (sidebars) that can be used in different parts of your WordPress theme, from homepage sections to footer columns.

// Register multiple widget areas
function register_custom_widget_areas() {
    // Homepage sidebar
    register_sidebar(array(
        'name'          => __('Homepage Sidebar', 'textdomain'),
        'id'            => 'homepage-sidebar',
        'description'   => __('Appears on the homepage', 'textdomain'),
        'before_widget' => '<div id="%1$s" class="widget %2$s">',
        'after_widget'  => '</div>',
        'before_title'  => '<h3 class="widget-title">',
        'after_title'   => '</h3>',
    ));

    // Footer columns
    for ($i = 1; $i <= 4; $i++) {
        register_sidebar(array(
            'name'          => sprintf(__('Footer Column %d', 'textdomain'), $i),
            'id'            => 'footer-' . $i,
            'description'   => sprintf(__('Footer column %d widget area', 'textdomain'), $i),
            'before_widget' => '<div id="%1$s" class="footer-widget %2$s">',
            'after_widget'  => '</div>',
            'before_title'  => '<h4 class="footer-widget-title">',
            'after_title'   => '</h4>',
        ));
    }

    // Shop sidebar (for WooCommerce)
    register_sidebar(array(
        'name'          => __('Shop Sidebar', 'textdomain'),
        'id'            => 'shop-sidebar',
        'description'   => __('Appears on shop and product pages', 'textdomain'),
        'before_widget' => '<aside id="%1$s" class="shop-widget %2$s">',
        'after_widget'  => '</aside>',
        'before_title'  => '<h3 class="shop-widget-title">',
        'after_title'   => '</h3>',
    ));

    // Above content area
    register_sidebar(array(
        'name'          => __('Above Content', 'textdomain'),
        'id'            => 'above-content',
        'description'   => __('Appears above the main content', 'textdomain'),
        'before_widget' => '<section id="%1$s" class="content-widget %2$s">',
        'after_widget'  => '</section>',
        'before_title'  => '<h2 class="content-widget-title">',
        'after_title'   => '</h2>',
    ));

    // Below content area
    register_sidebar(array(
        'name'          => __('Below Content', 'textdomain'),
        'id'            => 'below-content',
        'description'   => __('Appears below the main content', 'textdomain'),
        'before_widget' => '<section id="%1$s" class="content-widget %2$s">',
        'after_widget'  => '</section>',
        'before_title'  => '<h2 class="content-widget-title">',
        'after_title'   => '</h2>',
    ));
}
add_action('widgets_init', 'register_custom_widget_areas');

Display Widgets in Theme

// In your theme template files:

// Display homepage sidebar
<?php
if (is_active_sidebar('homepage-sidebar')) :
    dynamic_sidebar('homepage-sidebar');
endif;
?>

// Display footer columns
<footer class="site-footer">
    <div class="footer-widgets">
        <?php for ($i = 1; $i <= 4; $i++) : ?>
            <div class="footer-column">
                <?php
                if (is_active_sidebar('footer-' . $i)) {
                    dynamic_sidebar('footer-' . $i);
                }
                ?>
            </div>
        <?php endfor; ?>
    </div>
</footer>

// Display shop sidebar
<?php
if (is_shop() || is_product()) {
    if (is_active_sidebar('shop-sidebar')) {
        dynamic_sidebar('shop-sidebar');
    }
}
?>

Conditional Widget Areas

// Register widget areas for specific post types
function register_post_type_sidebars() {
    $post_types = array('portfolio', 'testimonials', 'services');

    foreach ($post_types as $post_type) {
        register_sidebar(array(
            'name'          => sprintf(__('%s Sidebar', 'textdomain'), ucfirst($post_type)),
            'id'            => $post_type . '-sidebar',
            'description'   => sprintf(__('Sidebar for %s post type', 'textdomain'), $post_type),
            'before_widget' => '<div id="%1$s" class="widget %2$s">',
            'after_widget'  => '</div>',
            'before_title'  => '<h3 class="widget-title">',
            'after_title'   => '</h3>',
        ));
    }
}
add_action('widgets_init', 'register_post_type_sidebars');

Check if Widget Area Has Widgets

// Display widget area only if it has active widgets
function display_widget_area($sidebar_id, $wrapper_class = '') {
    if (is_active_sidebar($sidebar_id)) {
        echo '<div class="' . esc_attr($wrapper_class) . '">';
        dynamic_sidebar($sidebar_id);
        echo '</div>';
    }
}

// Usage
display_widget_area('homepage-sidebar', 'homepage-widgets-wrapper');
