Thanks for your advises, I'm definetly going to develop a server side validation functionality. I think a client side validation is still useful even when there is a server side validation as it permits to avoid a lot of traffic/requests to the server;
I'm gonna fix my forms in this way. Here is the question: if I use the onsubmit event in my input type image button for javascript enabled browser, will the form be submitted without javascript support? (it should as the input type image submits the form by default...)

In most of my web sites, when a user submits form data, that data is usually processed and stored in some kind of database. I believe that it is good practice to never trust any data that is submitted from a form so I always validate it on the server. The consequences of incomplete or invalid data being inserted into a database could be devastating. Moving on, as I am generally very lazy when coding, I don't really see the point in validating the data on the client, if it has to be validated on the server. I guess you could claim that javascript is quicker to highlight errors in the form. I have always found a stream of javascript alerts when submitting a form to be quite annoying. That said, something I find even more annoying is a large form that is validated on the server, which when presented again if there is a validation error, has lost half the data you had submitted.
