Currently doing a example to have something to show, but I just can't get this to work. error I get when trying this code:

Code

Fatal _error_: Uncaught PDOException: SQLSTATE[42000]: Syntax _error_ or access violation: 1064 You have an _error_ in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' g, b = '-3', '213', '8' WHERE id = '4'' at line 1 in C:\xampp\htdocs\mysqlConfig.php:13 Stack trace: #0 C:\xampp\htdocs\mysqlConfig.php(13): PDOStatement->execute(Array) #1 C:\xampp\htdocs\example.php(333): query('UPDATE char SET...', Array) #2 {main} thrown in C:\xampp\htdocs\mysqlConfig.php on line 13

I'm not really great at this and just wanted to set up a example. Anyone have any idea what I did wrong? The code is to change RGB colors in a mysql table.
It also shows the current RGB in the form

PHP code:

PHP Code


<?php
if(isset($_SESSION['userID'])){
 $data = query("SELECT r, g, b FROM char WHERE id = :uid LIMIT 1", array(
 "uid" => $_SESSION['userID']
 ));
 if($data->rowCount() > 0)
 {
 $data = $data->fetch(PDO::FETCH_ASSOC);
 $r = $data['r'];
 $g = $data['g'];
 $b = $data['b'];
 }else{
 $_SESSION['userID'] = false;
 session_destroy();
 }
}
if(isset($_GET['changecolor_char1']))
{
 
 if(count($_POST) > 0)
 {
 {
 $ins = query("UPDATE char SET r, g, b = :r, :g, :b WHERE id = :uid", array(
"r" => $_POST['r'],
"g" => $_POST['g'],
"b" => $_POST['b'],
 "uid"       => $_SESSION['userID']
 ));
 header("Refresh:0");
 }
 }
 ?>

Form:

PHP Code


<?php 
<form action="" method="post">
 R:
 <input required="" name="r" autocomplete="off" value="<?php echo $r; ?>"/><br/><br/>
 G:
 <input required="" name="g" autocomplete="off" value="<?php echo $g; ?>"/><br/><br/>
 B:
 <input required="" name="b" autocomplete="off" value="<?php echo $b; ?>"/><br/><br/>
 </form> 


mysqlConfig.php:

PHP Code


<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

session_start();
$conn = new PDO('mysql:host=localhost;dbname=removed;charset=utf8', 'removed', 'removed');
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
function query($query = "", $params = array())
{
    global $conn;
    $stmt = $conn->prepare($query);
    $stmt->execute($params);

    return $stmt;
}
?>
