12 useful Woocommerce snippets & hacks

Here are 12 useful Woocommerce snippets and hacks I use on most of my sites. So, I would like to share them with you. If you want to use them then either paste them inside you theme’s function.php file or better yet, use Code Snippets plugin. If you to that then you will not lose the modifications during your next theme switch.

}

function featured_products_on_not_found() {
	echo '<h4>' . __( 'No products were found matching your selection. Although... You may be interested in these products', 'domain' ) . '</h4>';
	echo do_shortcode( '[featured_products per_page="4"]' ); // Here goes your shortcode

How to remove Woocommerce checkout fields without a plugin?

Here below are all the fields you can remove.

// Remove checkout fields
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

function custom_override_checkout_fields( $fields ) {
 // remove billing fields
    unset($fields['billing']['billing_first_name']); // Billing First name
    unset($fields['billing']['billing_last_name']); // Billing Last name
    unset($fields['billing']['billing_company']); // Billing company
    unset($fields['billing']['billing_address_1']); // Billing Address 1
    unset($fields['billing']['billing_address_2']); // Billing Address 2
    unset($fields['billing']['billing_city']); // Billing city
    unset($fields['billing']['billing_postcode']); // Billing postcode
    unset($fields['billing']['billing_country']); // Billing country
    unset($fields['billing']['billing_state']); // Billing state
    unset($fields['billing']['billing_phone']); // Billing phone
    unset($fields['billing']['billing_email']); // Billing email
   
    // remove shipping fields 
    unset($fields['shipping']['shipping_first_name']); // Shipping first name  
    unset($fields['shipping']['shipping_last_name']); // Shipping last name  
    unset($fields['shipping']['shipping_company']); // Shipping company  
    unset($fields['shipping']['shipping_address_1']); // Shipping address 1
    unset($fields['shipping']['shipping_address_2']); // Shipping address 2
    unset($fields['shipping']['shipping_city']); // Shipping city 
    unset($fields['shipping']['shipping_postcode']); // Shipping postcode
    unset($fields['shipping']['shipping_country']); // Shipping country
    unset($fields['shipping']['shipping_state']); // Shipping state
    
    // remove order comment fields
    unset($fields['order']['order_comments']); // Order comments
     return $fields;
}

You don’t have to paste all of them, instead use only these you need. For example, if you need to remove billing address 2, state and company fields then use this code here below.

// Remove checkout fields
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

function custom_override_checkout_fields( $fields ) {
 // remove billing fields

    unset($fields['billing']['billing_company']); // Billing company
    unset($fields['billing']['billing_address_2']); // Billing Address 2
    unset($fields['billing']['billing_state']); // Billing state
   
     return $fields;
}

How to make Woocommerce checkout fields optional?

Pay attention that “true” =required and if you want the field to be optional then set it to “false”.

add_filter( 'woocommerce_default_address_fields' , 'optional_default_address_fields' );
 function optional_default_address_fields( $address_fields ) {
 	$address_fields['first_name']['required'] = true;	 
 	$address_fields['last_name']['required'] = true;
 	$address_fields['company']['required'] = false;
	$address_fields['address_1']['required'] = true;
	$address_fields['address_2']['required'] = false;
	$address_fields['country']['required'] = false;
 	$address_fields['postcode']['required'] = false;
 	$address_fields['city']['required'] = false;
 	$address_fields['state']['required'] = false;
 return $address_fields;
 }
// For billing email and phone fields
add_filter('woocommerce_billing_fields', 'optional_checkout_fields1', 1000, 1);
function optional_checkout_fields1( $fields ) {
    $fields['billing_email']['required'] = true;
    $fields['billing_phone']['required'] = false;
    return $fields;
}

And once more, if you need a only couple of fields to be optional then just paste the lines you need. For example, this snippet makes country and phone fields optional.

add_filter( 'woocommerce_default_address_fields' , 'optional_default_address_fields' );
 function optional_default_address_fields( $address_fields ) {
	$address_fields['country']['required'] = false;
 return $address_fields;
 }

// For billing email and phone fields
add_filter('woocommerce_billing_fields', 'optional_checkout_fields1', 1000, 1);
function optional_checkout_fields1( $fields ) {
    $fields['billing_phone']['required'] = false;
    return $fields;
}

}
add_action('restrict_manage_posts', 'featured_products_filter');

function featured_products_filter_query( $query ) {
    global $typenow;

    if ( $typenow == 'product' ) {

        // Subtypes
        if ( ! empty( $_GET['featured_status'] ) ) {
            if ( $_GET['featured_status'] == 'featured' ) {
                $query->query_vars['tax_query'][] = array(

                    'field'    => 'slug',
                    'terms'    => 'featured',
                    'operator' => 'NOT IN',
                );
            }
        }

    }

}
add_filter( 'parse_query', 'featured_products_filter_query' );

		</select>
	';
	
	return $output;
}
add_action('woocommerce_product_filters', 'backend_onsale_filter');
 
/*

 */
function backend_onsale_where_statement($where) {
	global $wp_query, $wpdb;
 
	if (!is_admin() || $_GET['post_type'] != "product" || !isset($_GET['product_sale']) || $_GET['product_sale'] <= 0) {
		return $where;
	}
 
	$productsIDs = [];
	if ($_GET['product_sale'] == 1) {
		$querystr = '
			SELECT p.ID
			FROM ' . $wpdb->posts . ' p
			WHERE p.ID IN (
				SELECT post_id FROM ' . $wpdb->postmeta . ' pm WHERE pm.meta_key = "_sale_price" AND pm.meta_value > \'\'

Useful woocommerce related tips

Here are some of my favorite Wordpress tools

Thank you for reading this article. I hope you found it helpful as you build your own websites and e-commerce sites. Here are some tools I use as a Wordpress developer and enthusiast that I hope you’ll also find helpful.

These are affiliate links, so if you do decide to use any of them, I’ll earn a commission and this helps me create these tutorials and make Youtube videos. But in all honesty, these are the exact tools that I use and recommend to everyone, even my friends and family.

Themes: For the last couple of years I have two go-to themes which I use for every kind of projects. Those two themes are Blocksy theme and Kadence Theme. On this site and my Youtube channel you’ll see a lot of tutorials I have made about them. If you would like to get a 10% discount for both of them then:

Contact forms: There are hundreds of contact forms out there but Fluent Forms is the one I like the most. If you need a 20% discount then use this link (save 20% coupon is WPSH20).

Gutenberg add-ons: If I need a good Gutenberg blocks add-on then Kadence Blocks is the one I have used the most. You’ll get 10% discount with the coupon SIMPLEHACKS here.

Website migration: While building a website you probably need a good plugin that can help you with the migration, backups, restoration and staging sites. Well, WpVivid is the one I have used for the last couple of years. If you use this link along with the WPSH20 coupon you’ll get 20% discount.

Woocommerce extensions: There are a bunch of Woocommerce extensions that I really like but the one that stands really out is Advanced Dynamic Pricing. Once again, you’ll get a 20% discount if you use this link here (save 20% coupon is WPSH20)

Web Hosting: For getting started, I really like A2 Hosting. They have the dedicated and fast Wordpress hostinh and support has also been fast and responsive. If you’re more tech savvy and want to have a really fast managed cloud hosting then I recommend Cloudways. (Btw, this site is hosted in Cloudways.)

To see all my of most up-to-date recommendations, check out this resource that I made for you!
