This tutorial will show you how to create an AJAX form with PHP and jQuery. The AJAX form doesn’t look any different to an ordinary HTML form, with the exception of making sure that when we submit the form, it calls a javascript function rather than pushes the user to a page (causing a new page reload). I’ll also demonstrate how we can use ‘loading’ animation for the AJAX form, whilst we wait for the server to respond. Read More…
Need to limit the number of characters that are allowed to be entered into a textarea? I’ve crafted a little snippet that you can drop into your projects to achieve just that! It also provides a counter to the user, showing how many characters are remaining as they type.

Lots of tutorials coming up in the next few days – seeing as you guys are actually enjoying them! This is a really simple tutorial on how to write a jQuery plugin. It’s also a usable “Default Text” plugin, which sets some preset text in a form input, which clears when you focus the fiels.
It’s not as comprehensive as some other articles out there, as I wanted to keep this nice and simple. If you’re like me, you just want the simple tutorial – as you’ll enjoy building on it in the future!

Have you ever had a problem where you get a HTTP 403 error from submitting a form?
Does this form have a field that submits a URL?
If yes to the above two questions, I think I know the problem you’re having, and have a solution. It’s to do with mod_security (an Apache module) and the ‘http://’ part of the URL.
