Hi,

I'm really new to PHP so I'm sorry if any of these questions are really dumb.

I am trying to check weather people registering on my site are part of my current database. So what I have done is the following:

1. I have added two fields to the registration template. User ID number and User Membership number.

2. I have added the following code to register.php:

PHP Code:

    // Custom check for membership
    require_once('./includes/functions_membership.php');
    if (!check_membership($_POST['memberid'], $_POST['membernumber']))
    {
        $errors[991] = "Invalid membership information given, please check.";
    } 


3. I then created a file called functions_membership.php. And put the following code in it... (I'm pretty sure this is where you will all start laughing at me )

PHP Code:

<?php
error_reporting(E_ALL & ~E_NOTICE);

function check_membership($membershipID, $membershipnumber)
{

   $SAIMClink = mysql_connect( "localhost", "myUsername", "myPassword" );
   if ( ! $SAIMClink ) {
      die ( "Couldn't connect to MySQL: ".mysqlerror() );
   }

   mysql_select_db( "saimc", $SAIMClink )
      or die ( "Couldn't connect to MySQL: ".mysqlerror() );

   $result = mysql_query ( "SELECT name FROM users WHERE ID = '$membershipID' AND certificateNumber = 'membershipnumber'" );
   $num_rows = mysql_num_rows( $result );


   $i=0;
   while ($i < $num_rows) {
      $NameExists = mysql_result ( $result, $i, "name" );
      $i++;
   }
    mysql_close( $SAIMClink );
    
    if ($NameExists != ""){
       return true;
    }else{
       return false;
    }
    
}

?>

When I try to go through the registration process I get the following errors:

Warning: mysql_query(): 1 is not a valid MySQL-Link resource in /includes/db_mysql.php on line 212

Warning: mysql_error(): 1 is not a valid MySQL-Link resource in /includes/db_mysql.php on line 357

Any ideas where I might be going wrong?
