Count options specified in poll system

[ecopetition]

Hello there,

 

I'm making a polling system and have written the following code so far:

 

PHP:

if(isset($sumbit))
{
		$poll_title = (isset($_POST['poll_title'])) ? htmlspecialchars($_POST['poll_title']) : '';
		$poll_options_post = (isset($_POST['poll_options'])) ? $_POST['poll_options'] : array();

		$poll_options = array();
		$num_poll_choices = 0;

		$poll_questions = array();
		$num_poll_questions = 0;
		$poll_questions_post = (isset($_POST['poll_questions'])) ? $_POST['poll_questions'] : array();

		for($i = 0; $i < count($poll_questions_post); $i++)
		{
			$poll_questions[] = htmlspecialchars($poll_questions_post[$i]);
			if(! empty($poll_questions[$i]))
			{
				$num_poll_questions++;
			}

			for($j = 0; $j < count($poll_options_post); $j++)
			{
				if(! empty($poll_options_post[$j]))
				{
					$num_poll_choices++;
				}
			}

			if(! empty($poll_title) && $num_poll_choices < 2)
			{
				trigger_error('num_poll_choices');
			}
		}
}

Option 9: <input type="text" name="poll_options[]"/><br/>
Option 10: <input type="text" name="poll_options[]"/><br/>

 

Basically, when the user presses submit, it runs through the above process and either submits the poll to the database (the database functions aren't shown), or returns an error. If the poll poster wishes to post a question (note that if they want they can post only one question but have a maximum of 3 available, and each question can have a maximum of 10 options) but only specifies say, one answer instead of the minimum 2, then it returns an error ('num_poll_choices').

 

However, the bit that's confusing me is that if the user specifies one option in the first question and one answer in the second question the PHP thinks "two options have been specified so I can continue".

 

How do I make it know where the options were specified and which questions have only been given one option, which ones have two options, and which one has three options (in which case, continue).

 

I hope this isn't confusing, but if you can help I'd be really grateful.

 

Thanks a lot.

Thanks for your input, but it still isn't working. The poll is still being added to the database and not triggering an error.

[sasa]

where you add to db

[ecopetition]

The following code adds each bit to a different db table, it's mostly self-explanatory:

 

if(! empty($poll_title))
		{
			for($i = 0; $i < count($poll_questions); $i++)
			{
				if(empty($poll_questions[$i]))
				{
					continue;
				}

				$sql = "INSERT INTO poll_questions (question_text)
						VALUES('". $db->escape($poll_questions[$i]) ."')";
				$db->query($sql);
			}



			$poll_id = $db->last_id();
			for($i = 0; $i < count($poll_options); $i++)
			{
				if(empty($poll_options[$i]))
				{
					continue;
				}

				$sql = "INSERT INTO poll_options (question_id, option_text)
						VALUES('". $poll_questions[$i] ."', '". $poll_options[$i] ."')";
				$db->query($sql);
			}

			$sql = "INSERT INTO polls (poll_title, topic_id)
					VALUES('$poll_title', $topic_id)";
			$db->query($sql);

			$sql = "UPDATE topics
				SET has_poll = 1
				WHERE topic_id = $topic_id";
			$db->query($sql);

			define('META_REFRESH', "viewtopic.php?t=$topic_id&f=$forum_id");
			trigger_error('poll_added');
		}

try

<?php
if(! empty($poll_title))
{
$test = false;
foreach($_POST['poll_questions'] as $key => $questions)
{
	$poll_options = $_POST['poll_options'][$key];
	foreach ($poll_options as $k => $v) if (empty($v)) unset($poll_options[$k]);
	if(empty($questions) or count($poll_options) < 3)
	{
		continue;
	}
	$test = true;
	$sql = "INSERT INTO poll_questions (question_text)
						VALUES('". $db->escape($questions) ."')";
	$db->query($sql);
	$poll_id = $db->last_id();
	foreach ($poll_options as $option){
		$sql = "INSERT INTO poll_options (question_id, option_text)
						VALUES('". $poll_id ."', '". $option ."')";
		$db->query($sql);
	}
}
if ($test){
$sql = "INSERT INTO polls (poll_title, topic_id)
					VALUES('$poll_title', $topic_id)";

Sorry, it's still not working 

 

Personally I'm sure it has something to do with the first chunk of code.

Can anyone else spare their expertise to assist me please
