I have a problem when performing mysql commands when I invoke a function in another file. If I have the code in the same file, it works fine. The code looks like:
authenticate:
{
$conn = new mysqli($dbserver, "dbuser", "pass", $dbname);
$sql = 'SELECT userId, salt, pwd, isAdmin FROM users where username = ?';
$stmt = $conn->stmt_init();
$stmt->prepare($sql);
$stmt->bind_param('s', $username);
$stmt->bind_result($userId, $salt, $storedPwd, $isAdmin);
$stmt->execute();
$stmt->fetch();
}
Now, if I call a function, immediately after fetch, it fails on the bind_param line. I call it like this:
updateUserActivity ($conn, $tpcLang, 'LI', $userId);
the beginning of this function is:
function updateUserActivity ($conn, $lang, $activityType, $userId)
{
// check that activity is valid
$sql = 'SELECT activityType
FROM activityType
WHERE activityType = ?';
$stmt = $conn->stmt_init();
$stmt->prepare($sql);
$stmt->bind_param('s', $activityType);
$stmt->bind_result($activityTypeInDB);
$stmt->execute();
$stmt->fetch();
if ($activityType == $activityTypeInDB){
$success=1;
} else {
$success=0;
$msg = $lang->get('UPDATE_USER_INVALID_ACTIVITY_ERROR_MSG') . " " . $activityType . " (" . $stmt->errno . "): " . $stmt->error;
error_log ($msg);
}
// continue on to add a row in the userActivity table
}
The error I get on the bind_param is: invalid object or resource mysqli_stmt, and the DB error is: Commands out of sync; you can't run this command now.
Any suggestions would be greatly appreciated.
