Question

I’ve got a form on my website for users to input their fname, sname, company,phone,email which then gets updated to a database on submit. I also have a field in my database for a unique userID to incase users have same name and company ect. When submitting my form how is it possible to add in this field, a unique number so that it is +1 from the fields taken already. At the minute there are only 3 userIDs so i need the next inputted one to be 4 and so on.

At the moment I have this.

require_once('dbConnect.php');
//taken from a smarty template form.
$addForename = $_POST['forename'];
$addSurname = $_POST['surname'];
$addCompany = $_POST['company'];
$addContact = $_POST['contact'];
$addEmail = $_POST['email'];

public function addUser($addForename,$addSurname,$addCompany,$addContact,$addEmail)
{
    $sql = "INSERT INTO `Users` (`Forename`, `Surname`, `ComanyName`, `Phone`, `Email`) VALUES ('".$addForename."','".$addSurname."','".$addCompany."','".$addContact."','".$addEmail."')";
    $databaseAccess = new DatabaseConnect();
    try
    {
        $result = $databaseAccess->connect($sql, "add");
    }
   catch (Exception $e)
   {
       throw new Exception("Adding  User Failed !!!");
   }

   if ($result)
   {
       return 1;
   }
   else{return 0;}
}

thanks

If you are using phpmyadmin there should be a checkbox when youre creating a new column with “A_I” or Auto_Increment.. you have to check that and then it will count your entrys.
