Defining variables

Hi again,

Sorry for the vague subject, couldn't think how to explain it.

On a form, I have a number of Questions, and Answers which are submitted.

It's done like this:
FOREACH QUESTION
Question
<input name="answer<?php echo $counter ?>">
END FOREACH

Where $counter is a simple counter going up +1 for each question, so the answer to question 4, would be:

<input name="answer4">

I've done it like this as the number of questions can vary (list table in CMS).

So I have that working fine :)


It's just the results page, where I need to pull/define each variable from the _POST.

i.e

$answerXX = Trim(stripslashes($_POST['answerXX']));

So I need it to do this:

FOREACH COUNTER/ANSWER
$answerXXX = Trim(stripslashes($_POST['answerXXX']));
END FOREACH

I'm thinking we can control this foreach by defining the total number of records ($totalRecords), and running the foreach for every number from 1 up to $totalRecords.

So we get:
$answer1 = Trim(stripslashes($_POST['answer1']));
$answer2 = Trim(stripslashes($_POST['answer2']));
$answer3 = Trim(stripslashes($_POST['answer3']));
$answer4 = Trim(stripslashes($_POST['answer4']));
etc... until we hit $totalRecords

I just can't work out how to write a FOREACH statement which says foreach number from 1 up to $totalRecords.

Also I'd need to inject $counter into the XXX string of:
$answerXXX = Trim(stripslashes($_POST['answerXXX']));

I hope all that makes sense!

Cheers

Just a thought, instead of having to run a foreach between 1 and $totalRecords, could you do a loop, starting from 1 going up 1 each time, and breaking as soon as it finds a blank question number...

i.e. IF !$questionXXX, BREAK.

Just a thought. I don't know!
