In this week’s video tutorial, I’ll teach you how to take a simple, boring contact form and add some animations and an AJAX post request to submit the form to your MySQL database asynchronously.
In addition, we’ll also implement a bit of server and client-side validation to better secure our data. When submitting to the database, we’ll also review the most secure methods, including the use of prepared statements, which will bind the necessary values to each query, rather than embed them.

Conclusion
This screencast demonstrated just one way to animate your contact forms. Truthfully, it’s probably a bit too much for a regular site! :) But we’re here to have fun with it. If you decide to implement something like this into your own site, perhaps a more toned down version, please do leave a comment with a link to the page for our review!

It looks like MySQL Improved is not installed on your system. So you would either need to install it or just use mysql_connect.
Please help!
I followed up this tutorial step by step and I cannot add any comment to my database. I can retrieve information from database, but I cannot add anything.
I am not getting any errors or warnings.
I reviewed day11 of ‘diving into php’ and everything works fine. I can either add or get info from database. In this case when I click on ‘Post comment’ with filled form nothing happens, no information is added to the database.
The code I used is exactly the same as Jeffrey did. The database has been also created the same way.
Please help!
This add comment aplication include the reply Button?
How do I this to an existing webpage, like the comment section this is in?
Thanks
That’s so cool I was looking for comments HTML and I found more here .
Thanx :)
tnx for sharing!
Great tutorial, but what about escaping html entities? If you type say alert(‘hello world’) in the name field, that script is going to run on the site. Of course, if you’ve escaped it with php then it shouldn’t be a major problem and the rest of the site won’t be affected. Yet it is slightly unsettling to let it slip by. Any fix for that?
Great tutorial, but i´ve this problem. Please helpme!

This is nice and very interesting. Instant feedback mechanisms do take out a lot of pain from the contact forms.
