I have taken over as an impromptu web developer for my company and I am trying to make sense of some code written by the last person.
Here is some background on what I am really trying to do:
I want to create a class registration form that will either enter data to a database or email me the data. I want to do this securely as the form may contain credit card info. There is already an HR form online that we can enter job info and it saves to a mySQL db and then posts to our web in a job openings section. This form is username/password protected.
I am trying to read the php code in order to follow what is being done so I can replicate this into my new form. I ran across a check3.php page, which I don't know what it does. None of the other pages seem to reference this page.
So, my question is: What is the check3.php page and how should I go about my form to make sure it is secure? My initial thought is to make this form email me w/o the credit info, but then we'll have to call the person for that info. But that is not really a bad thing as then we can follow up to verify class registration.
