How to Reuse Sidebar Arguments in WordPress

Snippets by IsItWP

Are you looking for a way to reuse sidebar arguments? While there’s probably a plugin for this, we have created a quick code snippet that you can use to reuse sidebar arguments in WordPress.

While there are sites that have a bunch of sidebars, any argument you add to the array in register_sidebar will override the corresponding argument in $default_sidebar_args with the properties of array_merge. If you want to use a Heading 3 for just one sidebar, then that’s easy to do now.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

$default_sidebar_args = array(
    'before_title' => '<h2 class="widget-title">',
    'after_title' => '</h2>',
    'before_widget' => '<section id="%1$s" class="widget %2$s">',
    'after_widget' => '</section>'

// Site-wide sidebar
    array_merge( $default_sidebar_args, array(
        'name' => 'My Sidebar',
        'id'   => 'my-sidebar',
        'description'   => 'This is a sidebar.'
    ) )
// repeat register-sidebar as many times as you like, only changing, name, ID, and decription.
