Validating a form using php genoa dating

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.Also, our users will benefit from our friendly form – and the way it gracefully tells them when they’ve missed a field and such.But for the sake of our tutorial, I want to make it short and concise.

Of course, if there’s no errors – the form does a hard .submit() – to the same processing page and handled accordingly.But the bad thing about server side validation – is you see the page refresh.This is considered to be bad user experience – especially in mobile.Oh and of course, we will also have the good user experience of the page not refreshing when there’s errors. You can also have the processing page the same as the page where the form is. Copy the code below into your HTML: Nothing fancy here. Remember to make your field names unique – for this is what we’ll use to validate our form.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.Of course in the real world, you will have to check for valid email and such.The key to the code above is the check for an Ajax request. This is when it’s an Ajax request and we simply echo our error array in JSON format.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.So even when users turn off Javascript – you will see the same error messages. The submit action would be a processing page where our server side logic will take place.So every time we click the submit button, we go through each field in the form and create a data object.This object contains the field names and their respective values (you can also use j Query’s .serialize() for this purpose).
