Plz Help For Mailer Coding

i want to do mail to customer from database select but i am not successfully i write following code if any mistake in this code tell me

<?
$user_id = $_POST["userid"];
echo $user_id;
exit;
if($_POST)
{
mysql_connect("localhost","db_user","db_pass");
mysql_select_db("database");

echo $query = "select email_id from table1 where id = '".$_POST["userid"]."'";

$result = mysql_query($query);
$row = mysql_fetch_array($result);
$mail_to = $row["email_id "];

$body = $_POST["prd_sell"];
$phone_no =$_POST[" email"];
mail($mail_to,$mail_from ,$body);
mail($mail_to,$mail_from, $body, $phone_no);

}

?>

 

I tested this and I did not see a lot of problems. However, I have been having more luck using "mysql_fetch_object" than "mysql_fetch_array" With my method you would access the field by saying "$mail_to = $row->email_id"

I also noticed that you have some spaces in the quoted variables. This is a problem unless the form names and mysql column names contain spaces.

 

Your " mail();" function may be incorrect.

mail($to, $subject, $message, $headers);
