/*
1. Register the footer widget area
Open the functions.php file from the WordPress Theme Editor and search for the following line of code:
register_sidebar
That should take you to the area where all the sidebars are registered in your theme.
Add the following block of code just below the other sidebar registration code (we are telling it to register 3 footer widget areas):*/
register_sidebar( array(
'name' => 'Footer Sidebar 1',
'id' => 'footer-sidebar-1',
'description' => 'Appears in the footer area',
'before_widget' => '<aside id="%1$s" class="widget %2$s">',
'after_widget' => '</aside>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );
/*
2. Show the footer widget area in your theme
Open your footer.php file and insert the following block of code where you want to show the footer widgets (this will show the 3 footer widget areas if they have any widgets in them):
*/
<div id="footer-sidebar" class="secondary">
<div id="footer-sidebar1">
<?php
if(is_active_sidebar('footer-sidebar-1')){
dynamic_sidebar('footer-sidebar-1');
}
?>
</div>
