<?php

include "sql.php";

if ($_POST[action] == "insert"){

    $af = $_POST[af];

    $overskrift = $_POST[overskrift];

    $nyhed = $_POST[nyhed];

    $billede = $_POST[billede];

    mysql_query("INSERT INTO nyheder (af, nyhed, billede, overskrift, dato) values ('".$af."','".$nyhed."','".$billede."','".$overskrift."',now())") or die (mysql_error());
