WooCommerce: Capitalize All Product Names

When you deal with WooCommerce websites, you also need to look into design, readability, and accessibility. And if you have hundreds or thousands of products, you probably need to set some global rules so that you don’t need to worry about editing each product manually.

One rule could be the way product titles are displayed. Maybe you have a mix of capitalized product names (“Red Square Table”), non-capitalized ones (“White round chair”) and all caps ones (“GREEN COUCH”), and therefore you’re looking for a PHP shortcut to fix this automatically.

So, here’s a super simple solution to capitalize all product titles. Enjoy!

add_filter( 'the_title', 'bbloomer_capitalize_single_prod_title', 9999, 2 );

function bbloomer_capitalize_single_prod_title( $post_title, $post_id ) {
	if ( ! is_admin() && 'product' === get_post_type( $post_id ) ) {
		$post_title = ucwords( strtolower( $post_title ) );
	}
	return $post_title;
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
