Hvorfor skriver den ikke i databasen?

Hej!

Kan nogen fortælle hvorfor denne kode ikke skriver til databasen... Den kommer ikke med nogen fejlmeddelelser, men skriver den tekst der er skrevet i bunden...?

Er der en fornuftig forklaring?

<?php
include 'config.php';

$todb_publish = $_REQUEST["input_publish"];
$todb_title = $_REQUEST["input_title"];
$todb_author = $_REQUEST["input_author"];
$todb_theme = $_REQUEST["input_theme"];
$todb_info = $_REQUEST["input_info"];
$todb_article = $_REQUEST["input_article"];
$todb_approved_yes = $_REQUEST["approved_yes"];
$todb_approved_by = $_REQUEST["approved_by"];

$table_name = "$table_prefix$todb_publish$todb_title";

$tabelSQL = "create Table $table_name
(
    publish    varchar(50),
    title      varchar(50),
    author      varchar(50),
    theme      varchar(50),
    info        varchar(200),
    article    varchar(3000),
    approved    varchar(10),
    approvedby  varchar(50)
)";

$insert_to_db = "insert into $table_name set
    publish='$todb_publish', title='$todb_title', author='$todb_author', theme='$todb_theme', info='$todb_info', article='$todb_article', approved='$todb_approved_yes', approvedby='$todb_approved_by'";

$connection = mysql_connect("$db_url", "$db_user", "$db_pass");
mysql_select_db("$db_name");
mysql_query($insert_to_db);
mysql_close($connection);

//her skal komme nogle betingelser

echo "Dette blev skrevet til tabellen: <br />$todb_publish<br />$todb_title<br />$todb_author<br />$todb_theme<br />$todb_info<br />$todb_article<br />$todb_approved_by";
