Cookies and poll script

[slimjim]

Ok here is a small but easy poll script. I want to make it so that it uses cookies so that a person can vote one day and he try again it will not them until next day. I have no clue how to do it. Please help if you can.

<?php
include "../conf/sys.php";

if (! $vote && ! $result) {
	echo "<center>\n";
	echo "<FORM METHOD=\"POST\">\n";
	echo "<TABLE WIDTH=50% BORDER=1><TR><TD><TABLE WIDTH=\"100%\" BORDER=0>\n";
	echo "<TR><TH>$QUESTION</TH></TR>\n";
	while (list($key, $val) = each($ANSWER)) {
		echo "<TR><TD align=\"left\"><INPUT TYPE=\"radio\" NAME=\"answer\" VALUE=\"$key\"> $val</TD></TR>\n";
	} 
	echo "<TR><TD align=\"center\"><INPUT TYPE=\"Submit\" NAME=\"vote\" VALUE=\" Vote \"></TD></TR>\n";
	echo "<TR><TD align=\"center\"><INPUT TYPE=\"Submit\" NAME=\"result\" VALUE=\" See Result \"></TD></TR>\n";
	echo "</TABLE></TD></TR></TABLE></FORM></center>";
} else {

$file_array = file($RESULT_FILE_NAME); // or error("Can not open \$RESULT_FILE_NAME");

//  Save result

if ($answer < count($ANSWER) && $vote) {
	if (count($file_array) < count($ANSWER))  {
		$file_array = array("0\n", "0\n", "0\n", "0\n", "0\n", "0\n", "0\n", "0\n", "0\n", "0\n");
	}
	$old_answer = $file_array[$answer];
	$old_answer = preg_replace("/\n\r*/", "", $old_answer);
	$file_array[$answer] = ($old_answer + 1)."\n";

	$file = join('', $file_array);
	$fp = fopen("$RESULT_FILE_NAME", "w"); //or error("Can not write \$RESULT_FILE_NAME");
	flock($fp, 1);
	fputs($fp, $file);                                                     
	flock($fp, 3);
	fclose($fp);
	echo "<center><b>Your Vote has been recorded</b></center>\n";
}

//  Display result
while (list($key, $val) = each($file_array)) {
	$total += $val;
}

echo "<center>\n";
echo "<h3>$pollname Poll vote results :</h3>";
echo "<TABLE CELLSPACING=2 CELLPADDING=1 BORDER=1>";
echo "<tr><th>What</th><th>Percentage</th><th>Votes</th></tr>";

while (list($key, $val) = each($ANSWER)) {
	$percent =  $file_array[$key] * 100 / $total;
	$percent_int = floor($percent);
	$percent_float = number_format($percent, 1);
	$tp += $percent_float;
	echo "<tr><td> $ANSWER[$key] </td><td><img height=9 
	src=\"$IMG_DIR_URL/vote_left.gif\"><img height=9 width=\"$percent_int\" 
	src=\"$IMG_DIR_URL/vote_middle.gif\"><img height=9 
	src=\"$IMG_DIR_URL/vote_right.gif\"> $percent_float % 
	</td><td>$file_array[$key]</td></tr></center>";
}

echo "</TABLE><br>";
}
include "../templates/bottom.ihtml";

?>

First, you want to set the cookie!

setcookie ("Voted", "Yes", time() + 86400);

This code sets the cookie to expire after (current time + 86400) seconds which is 24 hours (1 Day)

Then, you set up an if statement...

<?php
   if ($_COOKIE['Voted'] == 'Yes')
      {
      echo ("Hey idiot, didn't I say to vote once a day?");
      }
   else
      {
      // Let the man vote, put that code in here!
      }
?>

[/SIZE]

NOTE: I set an INCOMPLETE COOKIE! Please read this to get a better idea of what values to send!

And another thing, I used $_COOKIE which was introduced in later versions of PHP. You may, depending on your host, need to use HTTP_COOKIE_VARS

Yet another note, you must send cookies FIRST before any HTML output or esle a HEADER ERROR will be generated. You can use Object Buffering in later versions of PHP!

Ok well the cookie does get placed i found that out. But the if statment. Doenst make alot of sence to me. I understand if the cookie is found then show the if.. but then we have the else statement. If it isnt found then else "what" ?

As it stands now the cookie is found, I am still able to vote. i go to the page and it shows the if statement.

if ($_COOKIE['Voted'] == 'Yes')
      {
      echo ("<center>Hey idiot, didn't I say to vote once a day?</center>");
      }
   else
      {
      // Not sure what to put in here ?
      }

But like i said I am still able to vote reagardless.

If a cookie is found i do not want a person to be able to vote again.
So if a person hits the vote button i want it to see if a cookie has been found and if there is then show the if statement. Else let them vote.

ANy of this making sence to anyone.

Thanks its sorta what I want but not.

If first time to vote today ... then let them vote and set cookie so that they can't vote for at least 24 hours again.

Right now statement isnt working like that on account of the if/else isnt set up right.

I want to use cookies and if/else statment. I am new to this and if someone could edit my code to have it work. So that I can see what I am not understanding.

Please help me out.

One more thing Thanks Kevin

[kevinsequeira]

just post your latest edited code where the cookie is being set ...

That worked... I knew it was that but when i did it i got nothing but errors..

Only one problem still....

If a cookie is found it does show the if statment... but

it isnt allowing me to see the poll results. Which i want a person to do if he has already voted within the 24 hours.

So I am assumming the if statement is wrong. Sence i really wouldn't want that echo statment anyways LOL

[slimjim]

See the way you set that up. It's not allowing after a person votes to see the results.
Right now if a person votes, They get the if statement instead of being directed to the results of the poll.

How can i get them to the results ?

[slimjim]

Ok I need help.
I just tested this again and it set the cookie without even voting. So regardless if i voted or not it sets the cookie and if I go back to the voting page it shows the if statement. Which is dumb.

So now i need to figure out not only how to bring the person to the results after voting. But i need to have the cookie set only if they voted.

So i am thinking the set cookie should come after the vote and the if statment before if they try to vote. But that will not work right cause set cookie has to come before any html ...HMMMM

Please any thoughts on how this should be done.

Newbie going crazy

[kevinsequeira]

hm, ure right.. try this code. look at the comments i have written in the code to help you debug

Well it is still allowing me to vote...its like the code has changed but back to square one. ....

Cookie not being set either....

Except now getting this error on results page:

Warning: Cannot add header information - headers already sent by (output started at /home/virtual/site3/fst/var/www/html/exchange/template/top.ihtml:2) in /home/virtual/site3/fst/var/www/html/exchange/clients/php_poll.php on line 57



I am not understanding this. This seems simple enough. 😕

From what I am seeing :

If voted already show results ( right ? )

Then

First time voting show form to vote ( right ? )

Set cookie

Then save Results

And if first time voting you get brought to the results page after you have voted.

It all looks right but not working. Is something missing ?

Thank You kevin for helping me with this. 🙂

[slimjim]

Well i have been at this and i cant figure it out.

So if anyone would like to give it a shot and let me know please go for it. Just look at previous posting to see where I am at.

This should be easy but its not. For a newbie i was thinking it should....man was i wrong from the start.

[slimjim]

OK this is what i have so far but the results after the first time voting are not working and still get an error.
Warning: Variable passed to each() is not an array or object in /home/virtual/site3/fst/var/www/html/aaa/clients/poll.php on line 9
Line 9 of course is :

     while (list($key, $val) = each($file_array)) {

VOting first time it works great. After the first time voting and then go back to the page and I should see just results. Well thats not working at all. Poll results are blank and get that error.
Please help if you can.
