php code:

$dbuser = "scott"; $dbpassword = "tiger"; $db = "orabis"; $conn = oci_connect($dbuser,$dbpassword,$db);  if (!$conn){     echo "connection error";     exit; }  $fname=$_post['first_name']; $sname=$_post['surname']; $email=$_post['email_address']; $address=$_post['address']; $selpass=$_post['select_a_password']; $confirm=$_post['retype_password'];  $sql = "insert become_a_member_110385461(first_name,surname,email_address,address,select_a_password,retype_password)  values ('".$fname."','".$sname."', '".$email."', '".$address."','".$selpass."', '".$confirm."')";  $stmt = oci_parse($conn, $sql); if (!$stmt) {     echo "error in preparing statement";     exit; }  oci_execute($stmt, oci_default); print "record inserted"; oci_commit($conn); oci_close($conn); 

change this

$fname=$_post['fname']; $sname=$_post['sname']; $email=$_post['email']; $address=$_post['address']; $selpass=$_post['pass']; $confirm=$_post['pass2'];
