Hi!

I developed my own add-on, here’s the code:

<?php
/**
 * Plugin Name: Product Unique ID
 * Description: Adds a Custom Field for Product Unique ID
 * Version: 1.0.0
 * Author: Marios A. Toparopoulos
 * Author URI: https://www.web-coders.net
 * Text Domain: puid
 * WC requires at least: 3.4.0
 * WC tested up to: 3.4.2
*/

// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) {
	exit;
}

/**
 * Display the custom text field
 * @since 1.0.0
 */
function puid_field() {
	global $post;
	$args = array(
		'id'            		=> 'product_unique_id',
		'name'							=> 'product_unique_id',
		'label'         		=> 'Product Unique ID',
		'type'							=>	'text',
		'placeholder'				=> 'Automatically Gets Filled',
		'class'							=> 'short puid-field',
		'desc_tip'      		=> true,
		'description'   		=> 'If value empty, on save will be replaced with post-id',
		'custom_attributes' => array (
			'readonly' => 'readonly', 
		),  
	);
	woocommerce_wp_text_input( $args );
}
add_action( 'woocommerce_product_options_general_product_data', 'puid_field' );

/**
 * Save the custom field
 * @since 1.0.0
 */
function puid_save_field( $post_id ) {
	global $post;
	$product = wc_get_product( $post_id );
	$value = $_POST['product_unique_id'];
	
	if (strlen($value) == 0 ):
		$title = $post->ID;
	else:
		$title = $value;
	endif;
	
	$product->update_meta_data( 'product_unique_id', sanitize_text_field( $title ) );
	$product->save();
}
add_action( 'woocommerce_process_product_meta', 'puid_save_field' );

I figured it out.
I was using a role that was created by a different plugin called User Role Editor
and Members & User Role Editor are not compatible.

This is my robots.txt

Is it “Disallow:” or “Disallow” with or without semicolon?
