Adding a errer in this code

NZ_Kiwi

i want to add a line which will give a error if the user has left a selected field blank! any ideas

also why does it add my password as normal tex? how do i add it as md5 ??


<?php
mysql_connect (localhost, user, pass);
mysql_select_db (table);
?>

<?php 

$qry = ("SELECT * FROM members WHERE username = '".$_POST['username']."'"); 
$countusername = mysql_num_rows($qry); 

// If the count is bigger than 0, echo an error, otherwise continue with the script. 
If($countusername > 0){ 
  echo "That username is already in our database.  Please go back andd try a different username."; 
} else { 




$result = mysql_query ("INSERT INTO members (`id`,`username`,`firstname`,`lastname`,`dob`,`address`,`city`,`country`,`phone`,`email`,`password`,`nz_mailing`,`active`,`warriors_mailing`,`bcc_mailing`,`level`) Values('','$username','$firstname','$lastname','$dob','$address','$city','$country','$phone','$email','$password','$nz_mailing','$active','$warriors_mailing','$bcc_mailing','$level')") or die("INSERT error: ".mysql_error()); 



}

?>

if (empty($varible)) {
	echo "Error has occured";
	exit; // stops the script here
}

so basically if $varible is not selected / has nothing in it then it displays an error.

ok, the error thing is easy but the MD5 thing still has me....

-------------------------------------------------
mainfile.php
-------------------------------------------------
include ('encrypt.php');

$password ="test";

$password2 = encrypt($password );

// $Password2 now = encrypted test

-------------------------------------------------
encrypt.php
-------------------------------------------------
function Encrypt($string) {
$crypted = crypt(md5($string), md5($string));
return $crypted;
}

this should give you the drift of it
