更新查询失败 php mysql

Question

$db = db_connect();

$title = $_POST['post_title'];
$content = $_POST['post_content'];
$id = $_GET['post'];
$userId = $_GET['id'];


$query =  "UPDATE post";
$query .= "SET title = $title, content=$content";
$query .= "WHERE id= $id";  

$result = mysqli_query($db, $query);

//Error handling 
if(!$result) {
    echo  "Query failed" . mysqli_error($connection);
    }
    else {
        echo "Post updated";
    }

db_disconnect($db);

The query fails and is not updated in phpmyadmin. I can't see what is going wrong and no error message is given.

I'm not sure if this is your only issue, but you need spaces in your query

// change this
$query =  "UPDATE post";
$query .= "SET title = $title, content=$content";
$query .= "WHERE id= $id";  

// to this
$query =  "UPDATE post ";
$query .= "SET title = '$title', content='$content' ";
$query .= "WHERE id = '$id'";
