Forms + session

[smeagal]

hi all..

I have this small problem with forms. This problem will happen only when I have session_start() on the form page. When I've submitted the page and hit the back button, the things that i've typed in the form was gone. This do not happen when I've removed the session_start() command. This is quite troublesome for users especially when they are filling a subscription form.

Is there any tips or tricks or whatever i should know?

thx in advance..

Register the variables within the session.... might be a solution...

I.e.

When the user first visits the form the tags as as follows

<input type=text name=bob value=$bob>

$bob is empty however, so no text will show up.

Register the variable, submit the form, now $bob has a value, and will be picked up when the form is reloaded as it takes it from the session....

Any clearer ?

thx The Chancer for replying. i've thought of that method... it might be a solution and i think it will work too. but i have to find a simpler solution since i'm facing lots of form and form fields right now. if there's no other solution, i am fried!!!

any other simpler methods you can think of?? or anyone??

[The_Chancer]

None that I can think of off the top of my head I'm afraid.....

You could do something like this:
$sname = "sid"; // Session name
$sid = session_id(); // Session ID
echo("<input type=\"hidden\" name=\"$sname\" value=\"$sid\">");

session_id() can be used to grab the current session id, even before it's sent back to the user.
