2. Add the following code snippet to create custom fields:

 add_action('woocommerce_product_options_general_product_data', 'add_custom_fields'); 

function add_custom_fields() {

global $woocommerce, $post;

echo ‘

‘;

woocommerce_wp_text_input(

array(

‘id’ => ‘_custom_product_text_field’,

‘label’ => __(‘Custom Text Field’, ‘woocommerce’),

‘placeholder’ => ‘Enter custom text here’,

‘desc_tip’ => ‘true’,

‘description’ => __(‘Enter the custom value.’, ‘woocommerce’)

)

);

echo ‘

‘;

}

add_action(‘woocommerce_process_product_meta’, ‘save_custom_fields’);

function save_custom_fields($post_id) {

$custom_field_value = $_POST[‘_custom_product_text_field’];

if (!empty($custom_field_value)) {

update_post_meta($post_id, ‘_custom_product_text_field’, esc_attr($custom_field_value));

}

}

3. Customize the code as needed to fit your specific field requirements.

4. Save the changes and verify the field is displayed on the product edit page.

3. Using Advanced Custom Fields (ACF) Plugin

Advanced Custom Fields is a powerful plugin for adding custom fields to any part of your WordPress site, including WooCommerce products.

Steps to use ACF to add custom fields:

1. Install and activate the ACF plugin from the WordPress Plugin Repository.

2. Go to Custom Fields > Add New to create a new field group.

3. Add the desired fields, such as text, image, or select.

4. Set the location rules to display these fields on WooCommerce products.

5. Use the following code snippet to display the fields on the front-end:

 if (have_rows('your_field_group_name')) : while (have_rows('your_field_group_name')) : the_row(); $field_value = get_sub_field('your_field_name'); echo '
' . esc_html($field_value) . '
'; endwhile; endif;
