Homemade Survey Help

[piecz]

I am playing around with creating a multipage survey and found a resource on the web that uses $stage to pass hidden variables in order to get the data values through subsequent pages.

I understand this but am having the following problem:

The example file has a submit button on the first question that opens a new window for the second set of questions. I want to be able to have the user answer the questions then hit a next link that will open the next set of questions within the existing window.

Ultimately I will dump the results into a unique data file for the survey taker, results to be correlated later.

I made sure to search for an example of this all day yesterday before pestering the forum but came up empty.

The sample code I am building from is listed below:

<?php
//first function grabs name
function display_name() {
global $PHP_SELF;

?>
<FORM TARGET="<?php echo $PHP_SELF; ?>" METHOD=GET>
Name: <INPUT TYPE=TEXT NAME="name"><BR>
<INPUT TYPE=HIDDEN NAME="stage" VALUE="cheese">
<INPUT TYPE=SUBMIT VALUE="Thanks!">
</FORM>
<?php
}
?>

<?php
//second function
function display_cheese() {
global $PHP_SELF;
global $name;

?>
<FORM TARGET="<?php echo $PHP_SELF; ?>" METHOD=GET>
Favorite Cheese: <INPUT TYPE=RADIO NAME="cheese" VALUE="brie">Very soft French Brie
<INPUT TYPE=RADIO NAME="cheese" VALUE="cheddar">Farmhouse English Cheddar
<INPUT TYPE=RADIO NAME="cheese" VALUE="mozzarella">Italian Buffalo Mozzarella

Favorite Times to Eat Cheese: <INPUT TYPE=CHECKBOX NAME="times[]" VALUE="m">Morning
<INPUT TYPE=CHECKBOX NAME="times[]" VALUE="n">Noon
<INPUT TYPE=CHECKBOX NAME="times[]" VALUE="d">Dinner
<INPUT TYPE=CHECKBOX NAME="times[]" VALUE="l">Late night

<INPUT TYPE=HIDDEN NAME="name" VALUE="<?php echo htmlspecialchars($name); ?>">
<INPUT TYPE=HIDDEN NAME="stage" VALUE="results">
<INPUT TYPE=SUBMIT VALUE="Thanks!">
</FORM>
<?php
}
?>

<?php
//process form is the same
function process_form() {
global $name;
global $cheese;
global $times;

if ($cheese == 'brie') { $cheese_message = 'I love brie.'.'<br>'; }
elseif ($cheese == 'cheddar') { $cheese_message = 'Cheddar is awesome!'.'<br>'; }
else { $cheese_message = 'Fresh mozzarella is divine.'.'<br>'; }

$favorite_times = count($times);

if ($favorite_times <= 1) {
$times_message = 'You should eat cheese more often.'.'<br>';
} elseif ($favorite_times > 1 && $favorite_times < 4) {
$times_message = 'Those are good times to eat cheese.'.'<br>';
} else {
$times_message = 'You are eating too much cheese.'.'<br>';
}

echo "Hello $name.".'<br>';
echo "$cheese_message $times_message";
}

?>

<?php

//page display logic
if (empty($stage)) { display_name(); }
elseif ($stage == 'cheese') { display_cheese(); }
else { process_form(); }
?>

Any help for this newbie would be great.

Is your problem just getting it to take place in the same window?

Try changing
TARGET="<?php echo $PHP_SELF; ?>"
to
action=\"" . $_server['php_self'] . "\"

Thanks for the suggestion Pig, unfortunately all I get are url not found errors. I replaced the code you suggested exactly as you asked.

Any other thoughts? I only want to ask about 5 questions per page and have the submit at the bottom of each page take the person to the next set of questions.

On the last page I want to write the results to a data file.

Thanks,

Tony

Sorry, I didn't realize that you weren't already inside <?php ?>
Since you are in HTML, not PHP, you need to do:
action=<?php echo($_server['php_self']); ?>

That makes it go to the same page, in the same window. The big piece is that you used target instead of action.

It is still giving me the url not found error..........

I really do apreciate your help Pig, this is driving me nuts.

Can you post the entire code?

This is the sample code I am working from with your suggestion .....

<?php
//first function grabs name
function display_name() {
global $PHP_SELF;

?>
<FORM TARGET="<?php echo $PHP_SELF; ?>" METHOD=GET>
Name: <INPUT TYPE=TEXT NAME="name"><BR>
<INPUT TYPE=HIDDEN NAME="stage" VALUE="cheese">
<INPUT TYPE=SUBMIT VALUE="Thanks!">
</FORM>
<?php
}
?>

<?php
//second function
function display_cheese() {
global $PHP_SELF;
global $name;

?>
<FORM action=<?php echo($_server['php_self']); ?> METHOD=GET>
Favorite Cheese: <INPUT TYPE=RADIO NAME="cheese" VALUE="brie">Very soft French Brie
<INPUT TYPE=RADIO NAME="cheese" VALUE="cheddar">Farmhouse English Cheddar
<INPUT TYPE=RADIO NAME="cheese" VALUE="mozzarella">Italian Buffalo Mozzarella

Favorite Times to Eat Cheese: <INPUT TYPE=CHECKBOX NAME="times[]" VALUE="m">Morning
<INPUT TYPE=CHECKBOX NAME="times[]" VALUE="n">Noon

<INPUT TYPE=HIDDEN NAME="name" VALUE="<?php echo htmlspecialchars($name); ?>">
<INPUT TYPE=HIDDEN NAME="stage" VALUE="results">
<INPUT TYPE=SUBMIT VALUE="Thanks!">
</FORM>
<?php
}
?>

<?php
//process form is the same

if ($cheese == 'brie') { $cheese_message = 'I love brie.'.'<br>'; }
elseif ($cheese == 'cheddar') { $cheese_message = 'Cheddar is awesome!'.'<br>'; }

$favorite_times = count($times);

if ($favorite_times <= 1) {
$times_message = 'You should eat cheese more often.'.'<br>';
} elseif ($favorite_times > 1 && $favorite_times < 4) {
$times_message = 'Those are good times to eat cheese.'.'<br>';
} else {
$times_message = 'You are eating too much cheese.'.'<br>';
}

echo "Hello $name.".'<br>';
echo "$cheese_message $times_message";
}

?>

<?php

//page display logic
if (empty($stage)) { display_name(); }
elseif ($stage == 'cheese') { display_cheese(); }
else { process_form(); }
