hi all,
Well i want to know, if i am typing some data in the textarea of a form and the form returns an error then how do i fill the text area with which user jus submitted the form..
- i tried doing it thru cookie, but cookie actually shows the value, after the page is refreshed once..
-Making session variables is a bad idea..
-Doing it thru hidden field is also not so professional ..
-Now the fourth option left is thru database, but do u think it is wise to have a temporary table to store posts and data like that ? WOnt it overhead the server ?
Please suggest me a method and i will stick to it :)
thanks :)

When your form is submitted via POST and returns, after invalid values, the receiving script can just echo the contents of your textarea, which is in the $_POST array, to the form text-area again. So your code for the textarea looks like:
[php]
<textarea name="kvt" cols="79"><?php echo (isset($_POST['kvt'])) ? $_POST['kvt'] : ""; ?></textarea>
[/php]
If not clear, show your code in this forum and we'll see.

Heya, Realin.
Making session variables is a bad idea..
Can you explain this one? I'm not sure that I understand (let alone agree).

i mean if i was to do that with session variables then,... i would have been creating a 2-3 sessions variables for every user and that can load my server a bit.. i just thot its not a good practice.. that is why i said so ..
rest u the expert :P

Adding 2-3 variables to each session file would increase the size of each file by approximately 20-30 bytes.
With 10,000 Users, that would mean that you would be using an extra 200-300 kb.
Given that most (paid) hosting plans start you off with at least 10 GB or so....

So that means saying "sessions variables are bad idea" was right on my part ?
is it ?
Heya, Realin.
What I'm saying is that using server-side sessions uses up a negligible amount of disk space.
If you had 10,000 Users, adding the 2-3 session variables would have taken up a mere 300 kb... which represents about .003% (that's three thousandths of a percent) of your total hard disk allocation on a 10 GB server. That's practically nothing.
