Custom Field on Packing Slip

Hi @mparsons501979,

You can add custom text to the packing slip by using one of our available action hooks. To check if the text has to be displayed you can use the helper function from this Stack Overflow answer that checks if the user already has made a purchase before: https://stackoverflow.com/questions/38874189/checking-if-customer-has-already-bought-something-in-woocommerce/46216073#46216073

Hi @mparsons501979,

Try adding this code snippet to your site:

/**
 * Show if it's a new customer on the invoice
 */
add_action( 'wpo_wcpdf_after_order_data', 'wpo_wcpdf_profit_amount', 10, 2 );
function wpo_wcpdf_profit_amount($template_type, $order) {
	if ($template_type == 'packing-slip') {
		if( !empty( $user_id = $order->get_user_id() ) ){
			$value = $user_id;
		} else {
			$value = $order->get_billing_email();
		}
		if( has_bought( $value ) ) {
		?>
		<span style="font-weight:bold;text-transform:uppercase">Returning Customer</span>
		<?php
		} else {
		?>
		<span style="font-weight:bold;text-transform:uppercase">New Customer</span>
		<?php
		}
	}
}

function has_bought( $value = 0 ) {
    if ( ! is_user_logged_in() && $value === 0 ) {
        return false;
    }

    global $wpdb;
    
    // Based on user ID (registered users)
    if ( is_numeric( $value) ) { 
        $meta_key   = '_customer_user';
        $meta_value = $value == 0 ? (int) get_current_user_id() : (int) $value;
    } 
    // Based on billing email (Guest users)
    else { 
        $meta_key   = '_billing_email';
        $meta_value = sanitize_email( $value );
    }
    
    $paid_order_statuses = array_map( 'esc_sql', wc_get_is_paid_statuses() );

    $count = $wpdb->get_var( $wpdb->prepare("
        SELECT COUNT(p.ID) FROM {$wpdb->prefix}posts AS p
        INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id
        WHERE p.post_status IN ( 'wc-" . implode( "','wc-", $paid_order_statuses ) . "' )
        AND p.post_type LIKE 'shop_order'
        AND pm.meta_key = '%s'
        AND pm.meta_value = %s
        LIMIT 1
    ", $meta_key, $meta_value ) );

    // Return a boolean value based on orders count
    return $count > 1 ? true : false;
}

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

Let me know if it worked!

I’m glad to know that it worked!

If you don’t mind and have the time, do you think you could leave us a review?

Thanks in advance and all the best with your store!
