I am pretty new in php programming and i'm facing with one trouble here. Probably it will be simple for all of you, but ok..

When i try to insert one row into mysql table named "novica" first time it works ok, but after that i'm unable to add any new row's. But when i delete this row, i can add one...but again, only one. I don't know what cause this.

here is my little php:

```
<?php
    $con = mysql_connect("localhost","root","password");
    if (!$con)
    {
        die('Could not connect: ' . mysql_error());
    }

    mysql_select_db("sola", $con);
    mysql_query("INSERT INTO novica (naslov, vsebina, avtor, ustvarjeno) VALUES('$_POST[address]', '$_POST[content]', 'Klemen', NOW())");

    mysql_close($con);
?>

```

And here is mysql export sql code:
