Hi!
I now work on a POLL system, and have an Question. How can I post the selected answer?
And then I Post that, add +1 vote for that answer.
Code:
<form action="[b]?????[/b]" method="post">
<h2><?php echo htmlspecialchars($poll['name']) ?></h2>
<ul>
<?php foreach($answers as $answer):?>
<li>
<input id="answer_<?php echo $answer['id'] ?>" name="poll_answer_id" type="radio" value="<?php echo $answer['id'] ?>" />
<label for="answer_<?php echo $answer['id'] ?>">
<strong><?php echo ($answer['answer']) ?></strong>
(<?php echo $answer['votes'] ?>)
</label>
</li>
<?php
endforeach;

I think you need a submit button
Code:
// poll_view.php
<form action="<?=site_url('/poll/pollhandler') ?>">
<?php foreach($answers as $answer) ?>
// options for each answer
<?php endforeach; ?>
<input type="submit" />
</form>
// controllers/poll.php
function pollhandler() {
$answer_id = $_POST['poll_answer_id'];
// process poll answer, add to database
// send them back where they came from
redirect($_SERVER['HTTP_REFERER']);

My table for answers:
votes_answers
id - answer id
pid -poll id
answer - answer name
votes - votes number
Other Question, how can sum the votes number?
So I need to SUM the votes value.
