Free online sex chat games - Validating forms using php

Of course everything is wrapped inside our document.ready() handler, then we put a .click() for our submit button.

So every time we click the submit button, we go through each field in the form and create a data object.

Of course, if there’s no errors – the form does a hard .submit() – to the same processing page and handled accordingly.

Of course, we have add our styling so our field will look like our screenshots above. Again, the styles are real basic and you probably want to do better in your own forms. We’ve combined best of both worlds: server side and client side validation in one solution (thanks to Ajax). If a field validation rule has to change – we only need to change it in one place: the server code.

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.

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.

Today I'll explain how to do form validation in PHP.

I'll take it up a level and re-write that script using the if, else conditional and empty() function to include form validation.

Also, our users will benefit from our friendly form – and the way it gracefully tells them when they’ve missed a field and such.

Let me know your thoughts and if you think this solution is a good fit for your projects.

Copy the following code into a text document then save and name it form.html: The action for the form is the same as the last form tutorial (send.php) but we'll re-write it now to include the changes.
