För att detta ska fungera måste du använda det globala variabelomfånget, som förklaras här: http://php.net/manual/en/language.variables.scope.php
$mysql_user = "NotTelling";
$mysql_password = "DefinatelyNotThis";
try
{
$dbh = new PDO("mysql:host=somehost;dbname=somename", $mysql_user, $mysql_password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$username = $_POST['username'];
$inPword = $_POST['password'];
$lat = $_POST['lat'];
$lon = $_POST['lon'];
$loggedin = "";
$password_hash = "";
$loggedinstatus = "";
$pts = "";
function getLoginInfo()
{
global $dbh, $username, $password_hash, $loggedinstatus, $pts;
$sth = $dbh -> prepare('SELECT pword, loggedin, points FROM login WHERE uname = :uname');
$sth->bindParam(':uname', $username, PDO::PARAM_STR);
while($row = $sth->fetch(PDO::FETCH_ASSOC))
{
echo $row['pword'];
echo $row['loggedin'];
echo $row['points'];
}
$password_hash = $fetch['pword'];
$loggedinstatus = $fetch['loggedin'];
$pts = $fetch["points"];
if($password_hash === null || $loggedinstatus === null || $pts === null)
{
die(json_encode(array("message" => "none")));
}
else
{
return "more";
}
}
function checkLoginCreds()
{
global $dbh, $inPword, $password_hash, $loggedinstatus, $username;
if(crypt($inPword, $password_hash) === $password_hash)
{
switch($loggedinstatus)
{
case "no":
$sel = $dbh->prepare("UPDATE login SET loggedin='yes' WHERE uname = ?");
$sel->execute(array($username));
return "AllGood";
break;
defaut:
return "alreadyin";
break;
}
}
else
{
return "BadLogin";
}
}
if(getLoginInfo() === "more")
{
echo json_encode(array("message" => checkLoginCreds()));
}
getLoginInfo();
}
catch(PDOException $e)
{
echo $e->getMessage();
file_put_contents('PDOErrors.txt', $e->getMessage(), FILE_APPEND);
}
Men det här kan bli rörigt mycket snabbt.
Jag föreslår att du lägger variablerna i en array eller använder OOP för en mer robust lösning:http ://php.net/manual/en/language.oop5.php
