Functions.php : Woocommerce Tricks

These are for my woocommerce custom codes and as always, please remember to create a child theme before installing these codes onto the functions.php file of your current theme.

To know how to create your own child theme, I recommend the Child Theme Configurator plugin.

When that is done, Activate your new child theme and Navigate to Appearance > Editor > functions.php

*** Also useful to note is anything is possible with Woocommerce with regards to custom filters and actions, here is their Action and Filter Hook Reference.***

To add a username field on checkout.

					function custom_override_checkout_fields( $fields ) {
$fields['account']['account_username']['placeholder'] = 'No symbols please';
$fields['account']['account_username']['label'] = 'Username';
$fields['account']['account_username']['type'] = 'text';
$fields['account']['account_username']['required'] = true;
return $fields;
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

To change the field label on the checkout form. For more field labels you can customize, click here.

					function custom_override_checkout_fields( $fields ) {
$fields['billing']['billing_company'] = array(
'label' => __('Dealership Name', 'woocommerce'),
'placeholder' => _x('Dealership Name', 'placeholder', 'woocommerce'),
'required' => true,
'class' => array('form-row-wide'),
'clear' => true
);return $fields;
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

To customize add-to-cart button text by product category.

					function custom_product_add_to_cart_text() {
global $product;
$terms = get_the_terms( $product->ID, 'product_cat' );
foreach ($terms as $term) {
$product_cat = $term->slug; // $term->name works too
case 'category1' || 'category2' || 'category3'; // Subscription Products
return 'Sign Up Now'; break;
case 'category5'; // Variable Products
return 'Price Options'; break;
case 'category7'; // One-time payment Deals
return 'Buy Now'; break;
return 'Add to Cart'; break;
add_filter( 'woocommerce_product_add_to_cart_text' , 'custom_product_add_to_cart_text' );
