Form Help

Im doing a questionnaire website. The amount of questions differ from questionnaire to questionnaire - this is causing me problems:

To fill in a questionnaire im using a for loop to print out the questionnaire to the screen - this works fine, but all the data is in a form, so im creating a string to identify the fields based on the loop - This works fine.

Another page is for processing the data and storing it in the database. I can get the data like: $variable = $_POST['A1'], where A1 is the answer to the first question.

BUT, heres the problem, in the processing page, because the amount of answers to questions im expecting is variable, i cant do as above, i need to loop it somehow. Creating a string bades on the loop and doing: $variable = $_POST['$name'], where $name is the string i have created (A1,A2,A3 etc.) doesnt work.

Im 100% stuck, any ideas????????????

What I would do in this case is add all the variable to an array instead of having individual variables for each of the question. Then you can pass the array to the processing script. Here's how you do it:

in the html:
<form action="processing.php" method="post">
Q1: <input name="answers[]">
Q2: <input name="answers[]">
Q3: <input name="answers[]">
Q4: <input name="answers[]">
</form>

in the php script:
foreach ($answers as $key => $value) {
add_answer_to_db ($db, $key, $value)
}

if course, you can actually have named array keys as well, just stubstite "answers[]" with "answers[q1]"

I knew it had to involve arrays some how, but i didnt know you could pass arrays around like that - This is going to make my life so much easier - THANK YOU!!!!!!!!!!!!!!
