I'm making a website. and one of the features i want it to have is to have a simple game that connects 2 players together. my problem is I don't know how to make it so both player are in the same "room" because on room holds only 2 players. On way i approached this is once one player joined, he gets a "wait for next player" message and waits while sending to the database that one player have joined. how do i make it keep checking for the next 3 minutes if the next player joined?
UPDATE
First here is the code so far:
<html>
<title>SiteName (test)</title>
<head>
<?php
$servername = "localhost";
$u
sername =
$password =
$dbname =
try
{
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $conn->prepare('SELECT * FROM game');
$stmt->execute(array('gameID' => $gameID));
while($row = $stmt->fetch()) {
print_r($row);
echo "<br />
";
}
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
?>
<button onclick="myFunction()" id="w">Look for Game</button><br>
<a href="https://www.google.com" id="lbl" class="button"></a>
<script>
function myFunction() {
var elem = document.getElementById("w").innerHTML = "Wait";
var counter = 10;
var label= document.getElementById("lbl");
var counter = 10;
var clabel= document.createElement("p");
clabel.innerHTML = "You can download the file in 10 seconds.";
var id;
label.parentNode.replaceChild(clabel, label);
id = setInterval(function() {
counter--;
if(counter < 0) {
clabel.parentNode.replaceChild(label, clabel);
clearInterval(id);
} else {
clabel.innerHTML = "You can download the file in " + counter.toString() + " seconds.";
}
}, 1000);
}
</script>
<?php
$conn = null;
?>
</body>
</html>
Am trying to make it so that if the first player joined, he will be waiting (i have it for 10 seconds here as a test) until the other joins. the way am trying to do it is to have a field in the database will know if the a player is in that page and await the next player. I read something about long polling but not sure how to implement it for my case.
Any feed back would be helpful, Thank you
