php oracle select statement help

[paintbawler1]

so here is my "simple" select in code that I want to work with my Oracle DB.

 

<?php
session_start();
$userid = trim($_POST['userid']);
$logPassword = trim($_POST['password']);
require("includes/dbconnect.php");
$query = "SELECT * FROM Users";
$query .= " WHERE UserID='$userid' AND Password='$logPassword'";
$statement = oci_parse($conn, $query);
if(oci_execute($statement))
{echo "good execution";}
else { echo "no execution";}
/*if($row = oci_fetch_assoc($statement))
{$SESSION['userid'] = $row['UserID'];
echo "You are a vaild user";}
else
{ echo "You are a invalid user";}
*/	
?>

 

the bottom part is just commented out for now because I keep getting this error:

 

Warning: oci_execute() [function.oci-execute]: ORA-01722: invalid number in /home/greer/public_html/validate_user.php on line 9

 

Line 9 being the oci_execute(). I'm not sure what is causing this error. My select statement seems correct and oci_pasre() came back as true. Anybody see what could be causing the problem. I didn't set up this server so am not sure if that is playing a factor. Thanks.
