Hi there, im a uni student working on an assignment I have just been given, this is my first time using php. so far I have mostly programed in C, C++.
anyway I have been given this relatively simple assingment where i have an online personality test that someone might fill in and I am to generate a response depending on the data recived.

So far I have been able to pull the values from txt boxes etc fairly easy however im stuck on this function that has a loop generating 5 radio buttons per question, and there is about 20 questions, it looks like this :

function writequestion(txt, qno)
{
  document.write("<li><b> ... " + txt + "</b><br>")
  document.write("Disagree")
  for (i=1; i<=5; i++) {
    document.write("&nbsp <input type=radio name=question[" + qno + "] value=" + i + ">" + i)
  }
  document.write("&nbsp Agree")
}

writequestion("is talkative", 1)
writequestion("does a thorough job", 2)
writequestion("is original, comes up with new ideas", 3)
writequestion("is helpful, unselfish with others", 4)

Im just woundering if someone can point me in the right direction with some suggestions on what variable i should be looking at capture and a general how too.. im not looking for a complete solution just somthing that can get me going in the right direction as I have been doing abit of research about value extraction from radio buttons but it all seems abit foregn.

thankyou in advance for any help you can offer.

Just thought I'd point out that the code you presented seem to be JavaScript, not php.

yea, its a javascript function in which im meant to capture the input from the user.
Im meant to be able to capture and display the results with my php code.

I hope that makes sense, im still fairly new at all this but thus far in my assignment I have been capturing text boxes and check boxes with my server side php script that then produces results to the client.

Before I try to answer your question, is there any particular reason you are using javascript to generate your form? If you're going to be using PHP you might as well generate it server side and just send the HTML code to the user:

PHP Code:

function writeQuestion($txt, $qno)
{
     echo "<li><b> ... $txt </b><br>";
     echo 'Disagree';
     for ($i=1; $i<=5; $i++) {
          echo "<input type=\"radio\" name=\"question[$qno]\" value=\"$i\"> $i";
     }
     echo 'Agree';
}

writeQuestion("is talkative", 1);
writeQuestion("does a thorough job", 2);
writeQuestion("is original, comes up with new ideas", 3);
writeQuestion("is helpful, unselfish with others", 4); 


When you retrieve the form data you'll do so using the $_POST array. PHP identifies form elements by the name attribute:

PHP Code:

$questions = $_POST['question']; 


In this case $questions is an array of all of the values associated with each question, in order.
