Using multiple buttons with PHP

[brian210]

I am currently trying to make a four question quiz. Each question is on a new page. There will be a previous button and a next button to take the user to the previous and next question respectively. There will also be a save button to save the current answer selected for the questions so far. Finally, I will have a submit button that will submit all the answers of the quiz and give back a score. I have to use these buttons, and I have to have my page setup in this way. However, I am not sure how I should handle the buttons.

I currently have my HTML file as such which will send to a php file:

<h1>Music Quiz</h1>
  <form action = "exam1.php" method = "post">
    <p>
      Which of the following composers were NOT famous during the
	  Renaissance period (1600-1750)? <br />
	  <select name = "questionOne">
	    <option></option>
	    <option value = "Guillaume Dufay">Guillaume Dufay</option>
	    <option value = "Josquin des Prez">Josquin des Prez</option>
	    <option value = "Henry Purcell">Henry Purcell</option>
	    <option value = "Palestrina">Palestrina</option>
	  </select>
	</p>
	<p>
          <input type ="button" value="Previous Question" />
	  <input type = "submit" value = "Save" />
          <input type = "submit" value = "Submit" />
          <input type = "button" value = "Next Question" />
	</p>
  </form>

The PHP file can print the next question if the next question button was selected, etc. I should be able to handle everything in the php file. However, I don't know how to determine which buttons were pressed in my php file. How should I handle the next and previous buttons? How do I know which submit button was selected? Any help will be greatly appreciated.

Give them different names

[brian210]

How do you refer to the names in the PHP code? How can I make the PHP handle next and previous? Any ideas?

$_POST['name']

How can I make the PHP handle next and previous? Any ideas?

save somewhere the sequence of the files and walk through that. (there are too many possibilities to list them all)
