Although UX and accessibility experts won’t like this customization, it’s still important to know “what’s possible” with WooCommerce.
In regard to the checkout form (billing + shipping + notes), there is a useful “woocommerce_checkout_fields” hook (filter) that is widely used by developers like me to alter the behavior of input fields.
In today’s episode we will take a look, indeed, at how to remove the checkout field labels from their default position (above fields), and use them as placeholders instead, so that we save up some vertical space.
PHP Snippet: Display Field Labels Inside Input Boxes @ Checkout Page
add_filter( 'woocommerce_checkout_fields', 'bbloomer_labels_inside_checkout_fields', 9999 );
function bbloomer_labels_inside_checkout_fields( $fields ) {
foreach ( $fields as $section => $section_fields ) {
foreach ( $section_fields as $section_field => $section_field_settings ) {
$fields[$section][$section_field]['placeholder'] = $fields[$section][$section_field]['label'];
$fields[$section][$section_field]['label'] = '';
}
}
return $fields;
}
Where to add this snippet?
You can place PHP snippets at the bottom of your child theme functions.php file (delete “?>” if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files
