We are making an voting system for our website. You can post reports to the website which are saved as data files.The current problem is that users can upvote or downvote as many times as they want because there is no barrier to stop the votes. What we want to happen is for users to be able to either upvote or downvote once.We are trying to use cookies to achieve this (not the best system, I know, since people can just clear cookies, but this is a small student project and we just need the system down). We are able to set cookies in the upvote and downvote script. We have a vote cookie which is either set to 0, -1, or 1, depending on whether the user upvoted or not.However, we are unable to retrieve the cookies accurately. When we try to retrieve the cookie vote using $_COOKIE["vote"] it doesn't give us a value.Is there any reason why this cookie is not returning a value? Thank you in advance. All of our code is provided below if you need it.
<?php
$report = $_GET["report"];
if(!isset($_COOKIE["vote"])) {
setcookie("vote", "0", time() + 315360000, $_SERVER['REQUEST_URI']);

}
function upvote() {

I have a text-based exploring game based off of HackingWithPHP that I'm working on, and my code just won't take input from the form I have for commands. It probably does take input, it's just that the PHP I have doesn't recognize it. Another problem is that the switch ($command) { statement that I have doesn't seem to run. It just skips over the entire thing. I can't figure out what's going on. Any help would be greatly appreciated.
Code:
index.php (I have this as a .php file so the $input variable can be passed from this file to game.php)
<html>
<head>
<title>Urban Adventure</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div class="container">
<div class="main">
<?php
include_once 'game.php';
?>
<FORM NAME ="form1" METHOD ="POST" ACTION = "">
<INPUT TYPE = "TEXT" VALUE ="" name="input" style="width: 600; position: absolute; bottom: 0; z-index: 2;">
</FORM>
</div>
<?php
$input = $_POST["input"];
?>
</div>
</body>
</html>
game.php:
<?php
include_once 'index.php';
print($input);
$World = simplexml_load_file("gameworld.xml");
$CurrentPos = 0;
$Done = 0;
print "<br>";
printplace();
function printplace() {
GLOBAL $World, $CurrentPos;
$Room = $World->ROOM[$CurrentPos];
$Name = $Room->NAME;
$Desc = wordwrap((string)$Room->DESC);
print "$Name<br>";
print str_repeat('-', strlen($Name));
print "<br>$Desc<br>";
if ((string)$Room->NORTH != '-') {
$index = (int)$Room->NORTH;
print "North: {$World->ROOM[$index]->NAME}<br>";
}
if ((string)$Room->SOUTH != '-') {
$index = (int)$Room->SOUTH;
print "South: {$World->ROOM[$index]->NAME}<br>";
}
if ((string)$World->ROOM[$CurrentPos]->WEST != '-') {
$index = (int)$Room->WEST;
print "West: {$World->ROOM[$index]->NAME}<br>";
}
if ((string)$World->ROOM[$CurrentPos]->EAST != '-') {
$index = (int)$Room->EAST;
print "East: {$World->ROOM[$index]->NAME}<br>";
}
print "<br>";
}
$input = explode(' ', $input);
print "<br>";
foreach ($input as $command) {
switch ($command) {
case 'north':
if ((string)$World->ROOM[$CurrentPos]->NORTH != '-') {
$CurrentPos = (int)$World->ROOM[$CurrentPos]->NORTH;
printplace() ;
} else {
print "You cannot go north!<br>";
}
break;
case 'south':
if ((string)$World->ROOM[$CurrentPos]->SOUTH != '-') {
$CurrentPos = (int)$World->ROOM[$CurrentPos]->SOUTH;
printplace() ;
} else {

}

}
break;
case 'east':
if ((string)$World->ROOM[$CurrentPos]->EAST != '-') {
$CurrentPos = (int)$World->ROOM[$CurrentPos]->EAST;
printplace() ;
} else {
print "You cannot go east!<br>";
}
break;
case 'look':
printplace() ;
break;
default:
print "not a valid command... <br>";
break;
}
}
print "<br>Thanks for playing!<br>";
?>
What happens is that the input doesn't work, the switch-case statement doesn't work, and the print "<br>Thanks for playing!<br>"; runs before the switch-case statement. Sorry if I can't describe this correctly. You might want to check out the real thing here: urbanadventure.dumpong.tk . You'll be able to see the real bugs going on there.

Im trying to make a poll in php. Im trying to gather data by writing the info to a txt file. How do I get the code to write the data to a txt file?
This all the code I have in my handler, how do I make it write to my txt file. Most of the stuff at the bottom doesn't matter yet. Try to look at the code that say if ($submit == 'submit') and what follows that.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>Poll</title>
</head>
<body>
<?php
//no need for sport validation is unimportant and doesnt work
if (isset($_REQUEST['Soda'])) {
$Soda = $_REQUEST['Soda'];
} else {
$Soda = NULL;
echo '<p class="error">You forgot to select your favorite soda!</p>';
}
//This is end of soda validation
if (!empty($_REQUEST['Book'])) {
$Book = $_REQUEST['Book'];
} else {
$Book = NULL;
echo '<p class="error">You forgot to write in your favorite book!</p>';
}
//End of book validation
if (isset($_REQUEST['SOTU'])) {
$SOTU = $_REQUEST['SOTU'];
} else {
$SOTU = NULL;
echo '<p class="error">You forgot to select the two biggest issues of the state of the union address!</p>';
}
//End of SOTU validation
if (isset($_REQUEST['Soda']) && !empty($_REQUEST['Book']) && isset($_REQUEST['SOTU'])) {
echo' Thank You for filling out the survey!<br> You can see the results of the pole' . " here!<br><br> Your response has been recorded.";
} else {
echo '<p class="error">Please go ' . "back" . ' and fill out the poll!<p>';
}
//End of link responses
//Define variables and make sure file works
$submit = $_REQUEST['submit'];
$filename = 'poll_data.txt';
$handle = fopen($filename, 'a');
//next is the stuff that is to be appended
if ($submit == 'Submit') {
fopen($filename, 'w');
$newdata = $Soda . PHP_EOL;
fwrite($handle, $newdata);
} else { echo 'You didn\'t click submit';}
//Now to sort the data and present it
/*explode('PHP.EOL', $filename);

I think if you use
fopen($filename, 'r');
that should work.

I'm using this script to list a few Twitch.tv streams and their status (offline or online).
If there are no online streams found, I want it to display a text saying that all are offline.
Code that checks if the added streams are online:
//get's member names from stream url's and checks for online members
$channels = array();
for ($i = 0; $i < count($members); $i++) {
if (isset($json_array[$i])){
$title = $json_array[$i]['channel']['channel_url'];
$array = explode('/', $title);
$member = end($array);
$viewer = $json_array[$i] ['stream_count'];
onlinecheck($member, $viewer);
$checkedOnline[] = signin($member);
}
}
unset($value);
unset($i);
//checks if player streams are online
function onlinecheck($online, $viewers)
{
//If the variable online is not equal to null, there is a good change this person is currently streaming
if ($online != null)
{
echo ' <strong>'.$online.'</strong>';
echo '  <img src="/images/online.png"><strong> Status:</strong> Online! </br>';
echo '<img src="/images/viewers.png"><strong>Viewers:</strong>  ' .$viewers.'</br>';
}
}

Is it because your $userGrab URL contains usernames twice? This is the URL whose contents you're retrieving:
http://api.justin.tv/api/stream/list.json?channel=painuser,ZombieGrub,Nathanias,Youbetterknowme,ncl_tv,painuser,ZombieGrub,Nathanias,Youbetterknowme,ncl_tv
Having looked at the response, it doesn't look like it's causing the problem. The strange URL is a result of you appending to the $userGrab string in the first foreach loop, after you've already added them with the implode() function call before. I think twitch.tv is rightly ignoring duplicate channels.
If all the values in $checkedOnline are null, everyone is offline. Put this at the end of your first code sample:
$personOnline = false;
foreach($checkedOnline as $person) {
if($person !== null) {
$personOnline = true;
break;
}
}
if(!$personOnline) {
echo 'No one is online';
}
else {
//there is at least someone online
}

$g = $_GET['e'];
$t = "Title!";

$p = '<p>'.$ep.'</p>';
}
if ($g == "nodata") {
errorput("Missing Something...", "Blank Field", "You left a box or few empty.");
} elseif ($g == "nopass") {
errorput("Password Incorrect!", "Encrypted Hash Unmatched", "Your password is probably wrong.");

So, it outputs html based on what it receives via GET.
Why doesn't it work?
$t and others aren't in global scope. Return them.

$g = $_GET['e'];
$t = "Title!";
$h = "";

return array(
$t,
$h,
$p

You are trying to use variables from outside the function inside the function which won't work like you think it is.
Please read up on variable scope: http://php.net/manual/en/language.variables.scope.php
If you changed your function to have:
At the top this would work how you want it to but it is wrong.
i added this JS code:
<script language="JavaScript" type="text/JavaScript">
var receiveReq = getXmlHttpRequestObject();
var mTimer;
var url = "www-rainbowcode-net/apps_dev.php/messagebox/list";
function getXmlHttpRequestObject()
{
alert("in gethttprequest");
if (window.XMLHttpRequest)
{
return new XMLHttpRequest();
}
else if(window.ActiveXObject)
{
return new ActiveXObject("Microsoft.XMLHTTP");
}
else
{
//document.getElementById('p_status').innerHTML = 'Status: Cound not create XmlHttpRequest Object.';
}
}
function getNewMessage()
{
if (receiveReq.readyState == 4 || receiveReq.readyState == 0)
{
alert("state is" + receiveReq.readyState);
//var params = "name" + name + "&" + "comment=" + comment;
receiveReq.open("POST", url, true);
receiveReq.onreadystatechange = processReqChange;
receiveReq.send(null);
}
}
function processReqChange()
{
// only if req shows "loaded"
if (receiveReq.status == 200)
{
alert("processed" + receiveReq.responseText);
document.getElementById("message_area").innerHTML = receiveReq.responseText;
}
else
{
alert("There was a problem retrieving the XML data:\n" +
receiveReq.statusText);
}
mTimer = setTimeout('getNewMessage();',2000);
}
</script>
then i have my html mixed with php:
<body onload = "return getNewMessage();">
<table width='96%' border='0'>
<?php
$cursor = $pager->getFirstIndice();
foreach ($pager->getResults() as $msg)
{
$has_freechat = false;

$freechat_req_link=link_to('Freechat',$freechat_req_link,'class=link_small_dark');
$cc = sizeof ($fc_records);
for($i = 0; $i < $cc; $i++)
{
if($fc_records[$i]->getProfileIdWith() == $msg->getProfileIdFrom())
{
$has_freechat = true;
break;
}
}
$unique_code_from = $msg->getRcProfileTableRelatedByProfileIdFrom()->getUniqueCode();

can anybody tell me why my alerts in the 2nd and 3rd function dont execute? the one in the 1st executes
thanks
in getNewMessage you miss () for processReqChange
update:
function getNewMessage()
{
if (receiveReq.readyState == 4 || receiveReq.readyState == 0)

alert("state is" + receiveReq.readyState);
