When in comes to validating forms, there are basically two techniques you can use: 1) Server-side validation and 2) Client-side validation.

Server-side validation is when form data is submitted, server analyzes then returns the user back to the form when items are invalid.

Keep in mind that you will need a bit of programming know how – especially in PHP and Javascript. So when our form submits, it passes the $_POST array to this page.

If you’re new to validating forms, the code below simply goes through the array and checks it against our rules for each field.

Note that in our case – I’m simply checking if first name and email is empty.

Of course in the real world, you will have to check for valid email and such.

POST) # Reference is now a bound instance with user data sent in POST # process data, insert into DB, generate email, redirect to a new URL,etc else: # GET, generate blank form form = Contact Form() # Reference is now an unbound (empty) form # Reference form instance (bound/unbound) is sent to template for rendering return render(request,'about/contact.html',) instance in listing 6-8.

I’ve seen solutions where they use both server side and client side – with validation rules in Javascript and their server language. Plus think of the maintenance of code that you have to do. What we’re trying to achieve is have the security of server side validation, the elegance of displaying the errors inline, as well as have a fall back behavior.

You would probably want to style this better, or even echo it out in the same page as the form.

But for the sake of our tutorial, I want to make it short and concise.

You will need some PHP and Javascript debugging experience to successfully integrate into your project.

Plenty argue (including myself), that server side validation is more secure.This object contains the field names and their respective values (you can also use j Query’s .serialize() for this purpose).
