Hello I am a Web Developer designing a web site for a client of mine. This is my first time working in php and I ran into a error trying to add a CR (Credit Card) processing with a marchant account. I need to know how to rewrite the html coding into php or how to add this simple task, into the registration form. I will compensate someone for helping me. my email is and my name is Justin L.

If you don't know how to process a credit card THEN DON'T!!!!!!!!!

Leave the CC processing to the payment gateway DO NOT EVER collect credit card details UNLESS your systems have PCI compliance with Secure Servers AND really good insurance.

thats really very true. If you do this you can also be in trouble along with your client.

What is your client's merchant service? If this is PayPal or Authorize.net etc. - they all have integration guide for their payment gateway (this is what chrishirst suggested to use). You will need to read integration guide and check their code samples before implementing payment form on your site. Most payment gateways provide sample integration code in PHP.
