Trying to make a simple Poll program

Truck35 · May 28th, 2014, 07:29 AM

I'm trying to create a program that will ask the user to choose between two questions, do calculations on the results, then display those results to the user. For some reason my program is not working . Please help me with my problem. My code is below:

Code:

<?php
$answerYes = null;
$answerNo = null;
 global $answer; 
 if (isset($_POST['submit'])){
 $answer = $_POST['answer'];
 echo $answer;
  if ($answer == 'Yes'){
$answerYes = file_get_contents('answerYes.txt') or die('ERROR: Cannot find file');
$answerYesTwo = (integer) $answerYes;
++$answerYesTwo;
file_put_contents('answerYes.txt',(string)$answerYesTwo) or die ('ERROR: Cannot write file');
echo "<p =\"choice\">Your choice was submitted</p>";
}
else if ($answer == 'No'){
$answerNo = file_get_contents('answerNo.txt') or die('ERROR: Cannot find file');
$answerNo = (integer) $answerNo;
++$answerNoTwo;
file_put_contents('answerNo.txt',(string)$answerNoTwo) or die ('ERROR: Cannot write file');
echo "<p =\"choice\">Your choice was submitted</p>";
}
 }
if (!isset($_POST['submit'])){
echo "<form action=\"Test.php\" method=\"post\">";
echo "<input type=\"radio\" name=\"answer\" value=\"Yes\">Yes</input>";
echo "<input type=\"radio\" name=\"answer\" value=\"No\">No</input><br>";
echo "<button type=\"submit\">Submit</button>";
echo "</form>";
}

Thanks,

Greetings,

Here you go;

Code:

<?php

$counter = 0;

if (isset($_POST['submit']))
{
	$choice = ( isset($_POST['answer']) ? $_POST['answer'] : '');
	if( !empty($choice) )
	{
		echo 'You selected: ' . $choice . '<br />';
	}
	else
	{
		echo 'No selection made, you must choose either \'Yes\' or \'No\'.<br />';
	}
	
	if ($choice == 'Yes')
	{
		$yes_count = file_get_contents('./answerYes.txt');
		if( $yes_count !== false )
		{
			$counter = (int) $yes_count;
			++$counter;
			file_put_contents('answerYes.txt',(string)$counter) or die ('ERROR: Cannot write file');
			echo '<p class="choice">Your choice was submitted</p>';
		}
		else
		{
			die('ERROR: Cannot find file');
		}
	}
	elseif ($choice == 'No')
	{
		$no_count = file_get_contents('./answerNo.txt');
		if( $no_count !== false )
		{
			$counter = (int) $no_count;
			++$counter;
			file_put_contents('answerNo.txt',(string)$counter) or die ('ERROR: Cannot write file');
			echo '<p class="choice">Your choice was submitted</p>';
		}
		else
		{
			die('ERROR: Cannot find file');
		}
	}
}

if (!isset($_POST['submit']) || !isset($_POST['answer']) )
{
	echo '<form action="_btest.php" method="post">';
	echo '<input type="radio" name="answer" value="Yes" />Yes';
	echo '&nbsp;&nbsp;&nbsp;';
	echo '<input type="radio" name="answer" value="No" />No<br />';
	echo '<button type="submit" name="submit">Submit</button>';
	echo '</form>';
}
?>
