php-数据未输入数据库

Question

I am trying to enter 3 different data to a mysql database 'pages' The first 2 data is submitted to the database but the third 'dname' is not.
The $_SESSION['dname'] contains the value to be added to the column 'dname'

The php looks like:

   if (isset($_POST['submit']))
{   
    $menulabel = $_POST['menulabel'];
    $content = $_POST['content'];
    $dname = $_SESSION['dname'];
    $query = "INSERT INTO pages (menulabel, content, dname) VALUES (?, ?, ?)";

    $statement = $databaseConnection->prepare($query);
    $statement->bind_param('sss', $menulabel, $content, $dname);
    $statement->execute();
    $statement->store_result();

    if ($statement->error)
    {
        die('Database query failed: ' . $statement->error);
    }

    $creationWasSuccessful = $statement->affected_rows == 1 ? true : false;
    if ($creationWasSuccessful)
    {
        header ("Location: index.php");
    }
    else
    {
        echo 'Failed';
    }
}

The mysql table:

     $query_pages = "CREATE TABLE IF NOT EXISTS pages (id INT NOT NULL AUTO_INCREMENT, menulabel VARCHAR(50), content TEXT, dname VARCHAR(50), PRIMARY KEY (id))";
    $databaseConnection->query($query_pages);

The php successfully adds the 'menulabel' and 'content' to the table and continues leaving the 'dname' NULL.
Please help, this is my first time with php.

Here you go buddy. This should fix your issue. Instead of throwing the object into the params, utilize it in the query instead.

$menulabel = $_POST['menulabel'];
$content = $_POST['content'];
$dname = $_SESSION['dname'];
$query = "INSERT INTO pages (menulabel, content, dname) VALUES (?, ?, '$dname')";

$statement = $databaseConnection->prepare($query);
$statement->bind_param('ss', $menulabel, $content);
$statement->execute();
$statement->store_result();
