php help (voting) ?

[jd2007]

this is the voting form:

 

<?php
echo "<form method='post' action='voting2.php'>
      Who do you think will be the next President of the United States ?<br>
      <input type='radio' name='NextPresident' value='Barack Obama' checked='checked' />Barack Obama<br>
      <input type='radio' name='NextPresident' value='Hilary Clinton' />Hilary Clinton<br> 
      <input type='submit' value='Vote' />
      </form>";
?>

 

voting2.php is :

 

<?php

$obama=0;
$clinton=0;
$time=getdate();

if (!$time[month]="August" && !$time[mday]=14 && !$time[year]=2007) {
echo "Thank you.";
if ($_POST["NextPresident"]=="Barack Obama") {
    $obama++;
}
else {
$clinton++;
}

}
else if ($time[month]="July" && $time[mday]=14 && $time[year]=2007) {

$total=$obama+$clinton;
$obama_perc=($obama /  $total) * 100;
$clinton_perc=($clinton /  $total) * 100;
echo "<img src='barack.png' width='$obama_perc' height='20'><br><br><img src='clinton.png' width='$clinton_perc' height='20'>";
}

else {}

?>

 

barack.png and clinton.png is a purple bar which acts as a graph bar. this thing i'm doing is a poll until august 14, 2007. users vote whether Barack Obama or Hilary Clinton will be President. after august 14, 2007, it does some calculation and controls barack.png and clinton.png size, so that it acts like a graph...pls check why its not working...pls help me ?

I am assuming the problem is due to neither having any values. Well, not actually not having values, but not having a divisible value (since 0 isn't divisible).

 

For example, try:

$obama=50;
$clinton=10;

 

How are you keeping track of the amount of votes each gets? 

[hostfreak]

I modified your code to get around your current problem, however I am still unsure how you plan to keep track of the votes and also keep track of who has voted already. I suggest a mysql database to keep track of the votes and to use sessions/cookies to keep track of people that have already voted.

 

test_form.php

      <input type='radio' name='NextPresident' value='Barack Obama' checked='checked' />Barack Obama<br>
      <input type='radio' name='NextPresident' value='Hilary Clinton' />Hilary Clinton<br> 
      <input type='submit' name='login' value='Vote' />
      </form>";

    if ($current_date != $end_date)
    {
        echo "Thank you.<br />";

        if ($_POST["NextPresident"] == "Barack Obama")

I think that the best way of keeping the trak of all the people who voted is to get their ip and store it because (at least me) people delete their cookies after using the browser.

About the code. Not sure what's the problem but maybe you should try doing something like this:

echo "<img src='barack.png' width='".$obama_perc."' height='20'><br><br>";

 

instead of this:

 

echo "<img src='barack.png' width='$obama_perc' height='20'><br><br>";
