To extract the postal code before checkout on WooCommerce, you can use the following steps:

  1. Locate the file where the checkout form is located in your WooCommerce theme directory. Typically, this file is called "checkout/form-shipping.php" or "checkout/form-billing.php".
  2. Insert the following code snippet in the desired location within the checkout form file to display the postal code field:
1
2
3
4
5
6
7
8
// Display the postal code field
woocommerce_form_field( 'postcode', array(
    'type' => 'text',
    'class' => array( 'form-row-wide' ),
    'label' => __( 'Postal Code', 'woocommerce' ),
    'placeholder' => __( 'Enter your postal code', 'woocommerce' ),
    'required' => true,
), $checkout->get_value( 'postcode' ));


  1. Once the postal code field is displayed on the checkout form, you can retrieve the entered postal code using the following code snippet in your theme's functions.php file:
1
2
3
4
5
6
7
add_action( 'woocommerce_checkout_process', 'extract_postal_code' );
function extract_postal_code() {
    if ( isset( $_POST['postcode'] ) && ! empty( $_POST['postcode'] ) ) {
        $postal_code = sanitize_text_field( $_POST['postcode'] );
        // You can now use the $postal_code variable for further processing
    }
}


  1. You can then use the extracted postal code for any further customization or validation before the checkout process is completed.


By following these steps, you can extract the postal code before checkout on WooCommerce and use it for customizing the checkout process as needed.
