How Long Do $_post Variables Stay Stored?

let's say that for whatever reason, let's say for a survey, i want to make a quiz like w3schools.com has, only with PHP. i would want to put all the questions on different pages, also like w3schools.

could each of the submissions stay stored inside PHP's $_POST for 20 pages? if not, how could i get around it?

PS. i really don't know anything about ASP other than the fact that w3schools uses it. so please don't explain to me with ASP-specific terms...

Take a look at the 'cool' quiz that I created a few days ago. Sub-Zero :: Cool Quiz Do you mean a quiz like that? However, once you leave the results page; when you come back your results are not there anymore! I think this may the thing you are asking about. If you want your results to stay saved, I believe that you should make a database table for the quiz.

Then you could use a simple MySQL query to insert the results in the database table. If you make the table, I could give you the query.

P.S. www.w3schools.com is coded in ASP. :-)

you may try to save the last_page_post_data into new page,using
<input type=hidden name=hidden_last_page_data value=last_page_post_data>
this tag may be invisible.

yeah, but if i were to use a database. i would have to automatically delete the results when they finish the test. then the database storage space and server speed would become inconsistent and too dependent on the quiz page...

The best way to store the data is just like lucifer star said, and this is the most widely used, pass the variables over to the next page and store them there with hidden values,eg. of code
CODE

<?php
//if the previous post variable is $_POST['name'];
//then in the next page after the form is submited do this
echo"<input type=\"hidden\" name=\"question1\" value=\"".$_POST['name']."\">";
?>

or alternatively a database like aproach.
store the answers of every page to a text file in the windows temporary directory ,then after calculating the results just delete the file after wards
and well if you dont delete it windows will, when you reboot the system
or the best alternative and i would recomend this. is use php sessions
every time the form is submited on the next page register the session varible with the value of the form, if you need code for that jus let me know

use hidden inputs..
<input type="hidden" name="lastquestion" value="$nameofthelastinput">
Put load of this in all pages, and you will save all them, simple, huh? ;D
by the way, you don't need to use $_POST["varname"], you can simply use $varname only, if register_globals is turned on (in trap17 it is).

  6. Session Variables
    Sessions in PHP behaving strangely (4)
    Hi. I am part of a development team working in PHP and MySQL. The site is using SSL, and users

    database and stored in session variables (functionality in the site is permissions specific).
    Lately, sessions are "disappearing" for no apparent reason. Users will log in, and at some point
    (the length of time will vary unpredicatably) the sessions will lose their value (the variables are
    empty) and this causes the site to evict the user. This is very frustrating for the user b....
