Form Back Problems??

darthmahon

Hey,

I have a some forms on my site and if users enter data incorrectly, they are presented with a message, basically it works like this:

if (!$submit)

{

show form

} else {

check form and output errors if need be and provide javascript.back link back to form to correct errors.

}

Problem is, I have this code at the top of all of my pages to check if the user is logged in or not.

// open session for user
session_save_path('path'); 
session_start();

Now if I have this at the top of the page with the form, if the user has entered data into the fields and makes a mistake, they get an error message and javascript.back link, when they click on that it should take them back to their form with the data they have already filled in, but it's all blank.

Now, if I remove that session_start() code it works fine and the data can be seen?

Any idea on how to fix this and allow the user to see the data already entered if they need to amend things? Otherwise they have to keep entering in their data which is VERY annoying for the user.

Cheers,
Chris

Counting on the back button is kind of silly since your counting on the browser to handle it properly and not all browsers were created equal.

Why force the user to click back? Its additional work you're putting on the user.

Why not redisplay the form with the form errors above the form and the form pre-filled out with the user's data (aka: use the POST/GET data)?

Rather than re-post it, take a look at a post I put in this thread below.

At the end I post code from a form and how I process it. The form posts to itself and if submit is detected it runs a validation function. The validation lets it go to other forms if all is ok, but if something fails the check (like an invalid email), it sends you back to the form. It also list to the user what form field failed AND MY FAVORITE PART: It will change the form text next to the field red. There is a lot of code so it is in the last 2 or 3 posts.

Here is the thread:
