Select Where don't work - user ID

Question

I work on a script, but this don't work, i don't know why.

So yea, this is the Code, who not work :

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $stmt = $conn->prepare("SELECT frage, status, antwort FROM kontakt WHERE userID = " . intval($row['userID']);
    $stmt->execute();

    // set the resulting array to associative
    $result = $stmt->setFetchMode(PDO::FETCH_ASSOC); 
    foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) { 
        echo $v;
    }
}

I think this is because ("SELECT frage, status, antwort FROM kontakt WHERE userID = " . intval($row['userID']);

I hope you can help me!

And this is the full code :

<?php
session_start();
require_once 'class.user.php';
$user_home = new USER();

if(!$user_home->is_logged_in())
{
        $user_home->redirect('index.php');
}

$stmt = $user_home->runQuery("SELECT * FROM tbl_users WHERE userID=:uid");
$stmt->execute(array(":uid"=>$_SESSION['userSession']));
$row = $stmt->fetch(PDO::FETCH_ASSOC);

?>

<?php include_once 'header.php'; ?>

Answer 1

您在第一条语句中缺少一个括号，它应该是$stmt = $conn->prepare("SELECT frage, status, antwort FROM kontakt WHERE userID = " . intval($row['userID']));

Answer 2

Syntax error in this line :

$stmt = $conn->prepare("SELECT frage, status, antwort FROM kontakt WHERE userID = " . intval($row['userID']);

Change to :

$stmt = $conn->prepare("SELECT frage, status, antwort FROM kontakt WHERE userID = " . intval($row['userID']));

missing ')'
