Create a Wordpress Plugin

A plugin for Mobile number verification at checkout page in WooCommerce: Purpose of this project: Non ethical customers may create several email ids to get Free trial of products. In this way they can easily cheat with company and enjoy services without paying a penny. Hence, an additional way to protect company from this unethical customers is by “taking manadatory mobile phone number” in woocommerce checkout page. Though there is a field for “Phone” in woocommerce checkout page but that is not mandatory. So customers just need an email id to get Free trial. To resist this, the “Phone” field must be mandatory and should be named as “Mobile Number”. Hint text should be “Example: 9234567890”. This field must be preceded with a mandatory field “Country Code”. Hint text should be “Example: +91” Just following the “Mobile number” field there should be “OTP” field with no hint text. Unethical customers may enter fake mobile numbers. Hence, there must be way to verify the mobile number by sending a random number OTP code to the entered mobile phone. That OTP code should be entered by customer into the field “OTP”. If OTP is similar then that mobile number with country code must be saved into database in a table with “email_id” and “mobile_number”. Next time if a customer puts the same Mobile number but different email id during checkout then checkout page will give error message that “Mobile number already registered for Email: <email_id>”. Hence, though a customer may try to cheat by using different email id but due to the Mobile Number mandatory field, his cheating can be resisted upto a certain extent.
