Tally Test Results.

Hello,
I have a 10 question form in multi-page view. (test_page1, test_page2) and would like the user to view their test results after submission. ie. Test Score: 80%

I'm attempting to this using PHP & placing the code in the "On Submit code - Section" of CF

I am able to create a simple loop statement but when referencing the form variables within the the PHP tags, I get a blank screen after submission. Removing {radio0} fixes the problem, and allows me to submit the form. I take it the syntax is incorrect.

---------my-code---------
<p class="style2">Congratulations, <strong>{first_name} {last_name}</strong> you have succesfully completed <strong>{testname}</strong>, Test.

Below are your score results.

<?php
for ($i=1; $i<=10; $i++)
{
if {radio0} <> 'true' echo "incorrect answer";
}
?>
---------code----------

What would be the simplest way to do this?
To allow the user to view their test results/grade?

Thank You
-Joe

Hi someguy2k,

I think the 'if' syntax is wrong. This line should have extra ()

if ( {radio0} <> 'true' ) echo "incorrect answer"; 

but it would be even better to spell it out

$radio0 = JRequest::getString('radio0', 'false', 'post');
if ( $radio0 != 'true' ) {
 . . .

Bob,
Thank You very much for your prompt reply...

[quote="GreyHead"]

if ( {radio0} <> 'true' ) echo "incorrect answer"; 

using the cf form variables: radio0, radio1, radio2, radio3, etc...gives me an error when submitting the form

$radio0 = JRequest::getString('radio0', 'false', 'post');
if ( $radio0 != 'true' ) {
 . . .

using the this code, I am able to submit the form but echo $radio0 doesn't display anything...

It seems I can't use any cf Vars within php tags. i.e echo {radi0}; will not work. Ultimately what I want is to compare the submitted info with an answer key.

Please let me know if this is beyond this level of support and/or where I can post for further/paid help.

Thanks again.

Hi someguy2k,

Please turn on debug for the form and them submit it. In the error messages with a blue background you should see a copy of the $_POST array which has all the results from the form. Please post that here so the we can see the raw data you are working with.

If echo $radio0 doesn't display anything then it's probably an array - try print_r ($radio0); instead.

Also in the first code you posted you have a loop for ( $i =1,. . . but you aren;t using $i inside the loop.

I suspect that you need to get help from someone with a bit more PHP knoweldge.

Hi Bob,
You were right on the money with everything. I'm learning PHP and didn't know how to loop through the $_POST array properly. Instead of replying back with more questions, I spent the ALL day researching and reading about Arrarys. Again, thank you for the support on this issue.

Below is the code of the project excluding the mySQL connection/declarations...

for ($i=0; $i<$num; $i++)
{
  foreach (array_keys($_POST) as $key) 
  {
    $$key = $_POST[$key];
   
      if ($key == 'radio0' || $key == 'radio1' || $key == 'radio2' || $key == 'radio3' || $key == 'radio4' || $key == 'radio5' || $key == 'radio6' || $key == 'radio7' || $key == 'radio8' || $key == 'radio9') 
{
   if (mysql_field_name($result,$i) == $key)
  {
     if (mysql_result($result,0,$i) ==  ${$key})
     { 
      $correct++;
     }
     if (mysql_result($result,0,$i) != ${$key})
     {
       $incorrect++;
      echo  "<font color='red'><b>Question # " . $question . " was incorrect";
      print "</font></b><br> Selected Answer: ${$key}<br />";
      echo  "Correct Answer: " . mysql_result($result,0,$i);
     }
  }
}
  
  }
$question++;
echo "<p>";
}
$score = $correct * 10;
echo "<br><br />";
echo "<p><b><font size='3'>Test Score: <font color='red' size='3'></b>" . $score . "%</font>";

Hi Joe,

Well done. It's good to see you learning useful new coding like this.
