Is this possible?

[bCourtney07]

With adodb, is it possible to have it return a value of 1 instead of -1? I want it to return a value of 1 if the user exists in a table.

 

here is my code

<?php
require("config.php");
if($_GET['action'] == 'post')
{
   if(empty($_POST['Employee_ID']) || empty($_POST['Date']) || empty($_POST['Activity']) || empty($_POST['Miles']))
    {
  error("blank");   //Prints out error message if fields are blank
  exit;
      }
      if(!empty($_POST['Employee_ID']))
      {
       $query="SELECT Employee_ID FROM analyzer_query WHERE Employee_ID = '{$_POST['Employee_ID']}'";
       $rs = $conn->execute($query);
       $num_columns = $rs->RecordCount();
       echo $num_columns . "<br>";
                    if($num_columns <= -1)
                        {
                          echo error ("user");
                          exit;
                        }
                        else
                        {
                        $conn->execute("INSERT INTO Activity_Log (`Employee_ID`, `Date`, `Activity`, `Miles`) VALUES ('{$_POST['Employee_ID']}', '{$_POST['Date']}', '{$_POST['Activity']}', '{$_POST['Miles']}')");
                        header("Location: success.php?action=success");
                        }
}
}
function error($error)
{
   if($error == 'blank')
      {
      echo "Please fill in all the required fields before submitting";
      }
   if($error == 'user')
      {
      echo "Please fill in the correct Employee ID";
      }
}
?>
