Error

[simjay]

Hey

I have a form to add data to my database. How can i get it to echo an error if "nameof" and "why" are not filled in?

<?php
$sql = "INSERT INTO adddb (nameof,why,userip) VALUES ('$nameof','$why','$userip')";
$result= mysql_query($sql, $conn) or die(mysql_error());

?>

thanks

empty() (http://us2.php.net/empty)

if(empty($val))
{
// error
}


Good luck
