Best Way To Protect Html Form Fields - Looking for suggestions on how to protect form fields during user inpu

My working example is here http://sonesay.trap17.com/application.php

The form submits to itself and stores what ever the user inputs into session variables. Thats all fine and I have validation checks for it, I wanted to add more and I remember comming across a site where they would lock from fields to prevent any changes if the information was already supplied and validated. I'm looking to build something similar but cant seem to figure out how to get that same effect at this time.

Heres my program logic so far application.php includes('application_content.php');

inside application_content i have my form. The form submits to itself checking validation and displaying 3 stages of the form (so far.. more to be added)
stage 0 - blank form, user just visited first time so display empty form
stage 1 - checks for post count if user submited form then run validations. if there are errors display errors and present same form for them to correct
stage 2 - no errors from pervious stage, just display the store session vars

Now the input field I'm interested in and particular concerned about is the date of birth field. Here I would rather the user use the javascript calender to pick a date then enter it manually. I hope this would eliminate any potiential errors like types or incorrect format. I mean this will save me doing validations

.

Well one method I used was to make it read only. I've tried making it read only from different stages e.g 0,1,2 of the form but once posted it somehow loses storage from the session its suppose to be assigned to. This is what is confusing me as you can see on stage 1 of the form when there are no errors I lock the fields as read only for the other input fields and when it gets submitted to stage 2 for display purposes it does get saved in the session.

Any ideas of how to go about this task would be much appreciated ^^.

heres my program logic for the form 'application_content.php'

ok after hours of serching I find this

I didnt even know 'readonly' attributes existed. Anyway It seems to work for me so far so if anyone else is looking for the same solution there you go.

Just a quick note if it essential to the security of the website that those fields remain unedited, this option is exploitable. Anybody can do a bit of javascript injection and make those fields editable again.

Thanks for the heads up on javascript injeciton, I never knew you could do that. Its a good think Its only intent is to try and keep the applications from users to join clean and valid as possible from user input. The applications posted to join will need to be approved by an admin or leader later on so I think it should be ok. I'll reemmber not to rely on this method for real important information being outputed back to the broswer.

Html Question Concerning Pre Tag And Code Tag - (8)

My question is, why would anyone use the CODE tag when you can use the PRE tag? 1. The PRE tag
recognises white space, the CODE tag does not. 2. The CODE tag requires that you escape some
chars, the PRE tag does not. I cannot see anything that the CODE tag achieves that is special apart
from sounding as though it is perfect for displaying code which IMO it is not. Thanks. ...

Html And Xhtml - serving the right kind (11)

Right now I have a site, which I've made XHTML 1.0 Strict. I am sending it as
application/xhtml+xml to browsers that say they can handle it, and as text/html to all other
browsers. Anyway, I started thinking that I'd much rather send proper HTML 4.01 to browsers that
don't understand XHTML instead of XHTML pretending to be HTML 4.01. It's not really a

can handle HTML, but not XHTML, may be (correctly) parsing CODE <p> Hello <br />

consider myself and advanced user of xhtml, but I know that its faster to use dreamweaver to code

entities to declare special characters such á é í ó ú or ñ, all of which always behave we...
