mduran16 on "[Plugin: WooCommerce - excelling eCommerce] Adding Drop Down menu to checkout"

Yeah, but im trying to find a way to do it without having to buy a $40 plugin. I only need to add one additional drop down box any ways, so I dont think its worth it honestly. I just want to know how to code it. I'll post what I have so far:

/**
 * Add the field to the checkout**/

add_action('woocommerce_after_order_notes', 'social_good_field');

function social_good_field( $checkout ) {

    woocommerce_form_field( 'social good', array(
        'type'          => 'select',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Social Good'),
		'clear' => false,
		'options' => array(
		'Good 1' => __( 'Montserrat', 'woocommerce' ),
		'Good 2' => __( 'Morocco', 'woocommerce' ),
		'Good 3' => __( 'Mozambique', 'woocommerce')
		),
        ),

		$checkout->get_value( 'social good' ));
}	 

/**
 * Process the checkout**/
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    global $woocommerce;

    // Check if set, if its not set add an error.
    if (!$_POST['social good'])
         $woocommerce->add_error( __('Please select a social good.') );
} 

/**
 * Update the order meta with field value**/

add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ($_POST['social good']) update_post_meta( $order_id, 'Social Good', esc_attr($_POST['social good']));
}
