// Code for saving WooCommerce Product Custom Fields

add_action( 'woocommerce_process_product_meta', 'woocommerce_product_custom_fields_save' ); 

Step 3# Adding Custom Product Fields

function woocommerce_product_custom_fields () {
global $woocommerce, $post;
echo '
';
// This function has the logic of creating a custom field
// This function includes input text field, Text area and number field
echo '
';
}

woocommerce_wp_text_input(
array(
'id' => '_custom_product_text_field',
'label' => __( 'My Text Field', 'woocommerce' ),
'placeholder' => 'Custom Product Text Field',
'desc_tip' => 'true'

'label' => __('Custom Product Number Field', 'woocommerce'),
'type' => 'number',
'custom_attributes' => array(

    $woocommerce_custom_product_text_field = $_POST['_custom_product_text_field'];
    if (!empty($woocommerce_custom_product_text_field))
        update_post_meta($post_id, '_custom_product_text_field', esc_attr($woocommerce_custom_product_text_field));

    // Custom Product Number Field
    $woocommerce_custom_product_number_field = $_POST['_custom_product_number_field'];
    if (!empty($woocommerce_custom_product_number_field))
        update_post_meta($post_id, '_custom_product_number_field', esc_attr($woocommerce_custom_product_number_field));

    if (!empty($woocommerce_custom_procut_textarea))
        update_post_meta($post_id, '_custom_product_textarea', esc_html($woocommerce_custom_procut_textarea));
}

<?php while (have_posts()) : the_post(); ?>
    <?php wc_get_template_part('content', 'single-product'); ?>

    <?php
    // Display the value of custom product text field
    echo get_post_meta($post->ID, '_custom_product_text_field', true);

    // Display the value of custom product number field
    echo get_post_meta(get_the_ID(), '_custom_product_number_field', true);

    // Display the value of custom product text area
    echo get_post_meta(get_the_ID(), '_custom_product_textarea', true);
    ?>
<?php endwhile; // end of the loop. ?>

    );
    woocommerce_wp_text_input($args);
}
add_action('woocommerce_product_options_general_product_data', 'woocommerce_product_custom_fields');

How to Exhibit Custom Fields on a Product Page in WooCommerce?

The following snippet reveals the custom fields. The process is straightforward. It first checks the custom field value and confirms it has a value. If the case is true, the value is generally displayed as the title of the field.

function woocommerce_custom_fields_display()
{
    global $post;
    $product = wc_get_product($post->ID);
    $custom_fields_woocommerce_title = $product->get_meta('woocommerce_custom_fields');

    if ($custom_fields_woocommerce_title) {
        printf(
            '<div><label>%s</label><input type="text" 
            id="woocommerce_product_custom_fields_title" 
            name="woocommerce_product_custom_fields_title" 
            value=""></div>',
            esc_html($custom_fields_woocommerce_title)
        );
    }
