What Are Custom Product Fields in WooCommerce?

Custom product fields are additional fields added to the product page to display or collect specific data. Examples include:

• Text fields for customer input (e.g., custom engraving text).
• Dropdowns to select variations.
• Checkboxes for optional add-ons.

With WooCommerce’s flexibility, you can add these fields using built-in tools, plugins, or custom code.

1. Adding Custom Product Fields with Built-In Options

WooCommerce offers built-in features like product attributes and variations, which can act as basic custom fields.

Steps to Add Attributes as Custom Fields:

1. Navigate to Products: In your WordPress dashboard, go to Products > Attributes.
2. Create New Attributes: Define attributes such as size, color, or material.
3. Add Variations: Assign these attributes to specific products under the Product Data tab.

While this method is limited to predefined options, it’s useful for straightforward use cases.

2. Using Plugins for Advanced Product Fields

Plugins offer a more flexible way to add custom fields to WooCommerce products without coding.

4. Save and assign the custom field to specific products.

This method is user-friendly and suitable for store owners without technical expertise.

3. Adding Custom Fields with Code

For developers, adding custom fields directly with PHP offers unlimited customization.

Steps to Add Custom Fields via Code:

1. Edit the Theme’s functions.php File:
   Add the following code to display a custom text field on the product page:
   php

   add_action('woocommerce_before_add_to_cart_button', 'add_custom_field');
function add_custom_field() {
echo '<div><label>Custom Text:</label><input type="text" name="custom_text" /></div>';
}

2. Save Field Data:
   Save the custom field input when a product is added to the cart:
   php

   add_action('woocommerce_add_cart_item_data', 'save_custom_field', 10, 2);
function save_custom_field($cart_item_data, $product_id) {
if (isset($_POST['custom_text'])) {
$cart_item_data['custom_text'] = sanitize_text_field($_POST['custom_text']);
}
return $cart_item_data;
}

3. Display Data in the Cart and Checkout:
   Ensure the custom field value appears on the cart and checkout pages.

This method is ideal for advanced users familiar with PHP and WordPress development.
