[RESOLVED] Online Survey

Sherrie

Before I begin to explain what I intend to do and where I'm having trouble, I'd like to state that I have checked the Manual as well as the newbie thread.

I have been given a task by my boss to develop an online employee opinion survey. This survey consists of 100 questions rated from 1 (Strongly disagree) to 6 (Strongly agree), 6 demographic questions as well as some free form questions.

I intend to have about 10 questions per page. Upon clicking the next page button, I'd like the answers of the 10 questions to be stored in session variables. On the last page when the submit button is clicked, all the data in the variables will be inserted into the web database.

How do I go about doing this? I more or less grasp session variables, arrays and the switch function separately, but I have no idea how to combine them.

Can anyone please point me in the right direction? I would greatly appreciate it! Have tried searching for sample web surveys but I'm not having that much luck.

Thanks in advance!

Do you want this to be a reuseable script (with admin, etc.) or just hardcode it all?

the first option would probably more viable, however, it would involve quite a bit of time. i personally would store the answers like this:

answer question 1 = $SESSION[1]
answer question 1 = $SESSION[2]
etc.

if there are multiple answer questions, the first and second answer to question 3 would be in
$SESSION[3][1]
$SESSION[3][2]

so far for my rough draft...
or, to make it a little cleaner:
$SESSION['answers'][1]
$SESSION['answers'][2]
$SESSION['answers'][3][1]
$SESSION['answers'][3][2]

sid,

Thank you for your response!

I don't really understand what you mean by a reusable script or hardcoding.

Also, as each question only has one answer, and the participants may choose not to answer a particular question, would I store the session variables as follows?

Q1 = $SESSION[1]
Q2 = $SESSION[2]
Q3 = $_SESSION[3]

Where do I create the array $_SESSION['answers']?

Lastly, how do I assign the values to the session variables? The only way I can think of is:

switch($q1)
{
   case 1;
        $_SESSION[1]=1;
        break;
   case 2;
        $_SESSION[1]=2;
        break;
   case 3;
        $_SESSION[1]=3;
        break;
   case 4;
        $_SESSION[1]=4;
        break;
   case 5;
        $_SESSION[1]=5;
        break;
   case 6;
        $_SESSION[1]=6;
        break;
   default;
        $_SESSION[1]="";
        break;
}

This seems rather longwinded and messy, especially with over 100 questions. There must be an easier way, right?

Look forward to your reply!

Thanks again!

Hi Sherrie

Not sure if this is what your looking for. I have added the examples as it's easier to show than explain!
Just create 3 pages:
test_session1.php
test_session2.php
test_session3.php
and copy below.

<?php
session_start();
session_unset();
if (isset($_POST['Submit'])) {
$_SESSION['answer'][0] = $_POST['question1'];
$_SESSION['answer'][1] = $_POST['question2'];
$_SESSION['answer'][2] = $_POST['question3'];
$_SESSION['answer'][3] = $_POST['question4'];
header("Location:test_session2.php");
}
?>

mark_kccs,

Thank you for your response, that was pretty much what I was looking for!

A few questions, though:

Why is there a need to unset the session after starting it?
I don't understand the isset line
Can i use Dreamweaver to get the HTML part then just add in the PHP code in the header?
What happens when the user returns to previous pages? Will the answers still be reflected? If not, how do I make it so that it does?

Thanks a lot! Appreciate it!

Sherrie

mark_kccs,

I have tried your example, and it works! Thank you for that!

However, I can't seem to display the answers when the user goes back to previous pages.

How do I code it so that the pages display the answers from the session variable?

Would appreciate any help.

Thanks again!

Sherrie

I've found the solution to my problem, just in case anyone else is looking for the same thing that I was. Here is the code which I used:

<input type="radio" name="q1" value="1" <?php if($_SESSION['answer'][0] == '1') print 'checked="checked" '; ?>/>
<input type="radio" name="q1" value="2" <?php if($_SESSION['answer'][0] == '2') print 'checked="checked" '; ?>/>
<input type="radio" name="q1" value="3" <?php if($_SESSION['answer'][0] == '3') print 'checked="checked" '; ?>/>
<input type="radio" name="q1" value="4" <?php if($_SESSION['answer'][0] == '4') print 'checked="checked" '; ?>/>
<input type="radio" name="q1" value="5" <?php if($_SESSION['answer'][0] == '5') print 'checked="checked" '; ?>/>
<input type="radio" name="q1" value="6" <?php if($_SESSION['answer'][0] == '6') print 'checked="checked" '; ?>/>

Thanks for all your help!

Can't seem to find the button to mark the thread as resolved, though!

Hi Sherrie

Sorry been off-line for a while but glad I could help.
The reason I used Session_unset was to reset the session array ($_SESSION['answer']) if the user wanted to start over again from the first page. I use dreamweaver so yes it is possible. isset checks that a variable etc has a value and I use it to check that the submit button has been submitted so that I can keep my code in one page.

Good luck with your project
