Add Radio Form Values with PHP

[vigiw]

Hello,

 

I've tried creating a form for a "quiz" (not a right-wrong quiz, but one which scores numbers of values for each selection for a specific result) using Javascript, but it didn't work out.  I was wondering how, using the same form, I could go about doing this in PHP (if possible).  I gave up on Javascript because it kept showing "NaN" for the calculated score, even though every value is a number, but some are negative (e.g. -5 for one value; 3 for another).

 

Any help for this would certainly be appreciated.

 

Thanks!

Ok... I've created a code for my need as described above, and the form's submit button will POST to my php file.  But when I submit, the PHP page comes up blank.  Here's the code:

 

<?php
$q1 = $_POST['q1'];
$q2 = $_POST['q2'];
$q3 = $_POST['q3'];
$q4 = $_POST['q4'];
$q5 = $_POST['q5'];
$q6 = $_POST['q6'];
$q7 = $_POST['q7'];
$q9 = $_POST['q9'];
$q13 = $_POST['q13'];
$q17 = $_POST['q17'];
$q18 = $_POST['q18'];
$q19 = $_POST['q19'];
$q8 = $_POST['q8'];
$q10 = $_POST['q10'];
$q11 = $_POST['q11'];
$q12 = $_POST['q12'];
$q14 = $_POST['q14'];
$q15 = $_POST['q15'];
$q16 = $_POST['q16'];
$soc = $q1 + $q2 + $q3 + $q4 + $q5 + $q6 + $q7 + $q9 + $q13 + $q17 + $q18 + $q19;
echo "You are" $soc; "% Socially"
if ($var >= 50)
    echo " Liberal<br>";
    else
  echo " Conservative<br>";
$ec = $q8 + $q10 + $q11 + $q12 + $q14 + $q15 + $q16;
echo "You are" $ec; "% Fiscally (Economcially)"
if ($var >= 50)
    echo " Liberal<br>";
    else
  echo " Conservative<br>";
?>

 

Any ideas?

Thanks in advance!

$ec = $q8 + $q10 + $q11 + $q12 + $q14 + $q15 + $q16;
echo "You are $ec% Fiscally (Economically)"'
if ($var >= 50) {
    echo " Liberal<br>";
}   else
  echo " Conservative<br>";
}
?>

 

That should work.  You messed up the echo statements with the variables in them.

$var is not defined.

 

if($soc >= 50){

Nice catch.
