Hi there,
I'm confident that I will help you create an extra field on the WooCommerce product page to put the phone number. I will add validator to check if the phone number is valid.
I have 7 years of experience creating websites, web applications and software for companies like Flash footwear, Nur Fashions and many more. I have good experience in Website Management, WordPress, Magento, Shopify, MySQL, PHP, CodeIgniter.
Please leave a message to discuss more regarding this project.
Regards,
Nooruddin S.
