abigail posted a topic in Effortless E-Commerce with PHP and MySQL (2nd Edition)I'm working on an online store application. I'm working on the part that will get Customer's shipping address. I also want to get name, email, and phone number. My question is, what is the best way to validate all of these, especially the address. I know this is a general way of stating the question, so to clarify, this is what I am thinking. I have two goals: 1) all the data is valid in the sense I can store it in the database. 2) I want to try to make sure it is a real customer, not a scammer, so I would like to make sure everything is in a valid form. Such as a zip code is only 5 digits plus 4. A phone number is only 10 digits, etc. Is it reasonable to check if the zip code is valid for that state? I don't think it needs to be perfect. It is just for doing some basic checking before passing it through to the credit card section.
I am having trouble creating the code to improve the security of add_print.php in Chapter 19. I am adapting the code from chapter 11 to this problem and not having any luck. I want to validate the file type before adding a print to the database. Does anyone have the solution to this review and pursue question? thanks
I am trying to create a form with check boxes so the data will be sent by email. When two boxes are checked, only one value is passed. Can you show me how to get and validate check boxes data so I can use a booking form on the website? Thank you
