Hi all,
I know very little about PHP, my Dad made a contact form for me some time ago and I have attempted to use it on a new site and it won't to pick up the values from the form fields. I wish I could ask him about it (and about loads of other things 
) but he passed away last year.
I have done some research and I managed to run phpinfo on each of the servers and discovered that register_globals is set to off on the new server. Am I right in assuming that this has something to do with the problem I have?
If so, is there anyone out there who can tell me what do I need to do to my code to get it to work on this server, and indeed if I have to use it on PHP6 in the future?
The code is below.
<?php
function field_validator($field_descr, $field_data, $field_type, $min_length="", $max_length="", $field_required=1) {
# array for storing error messages
global $messages;
# first, if no data and field is not required, just return now:
if(!$field_data && !$field_required){ return; }
# initialize a flag variable - used to flag whether data is valid or not
$field_ok=false;
# a hash array of "types of data":
$data_types=array(
"email"=>"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
"digit"=>"^[0-9]$",
"number"=>"^[0-9]+$",
"telephone_number"=>"^[ +0-9]+$",
"alpha"=>"^[a-zA-Z]+$",
"alpha_space"=>"^[a-zA-Z ]+$",
"alphanumeric"=>"^[a-zA-Z0-9]+$",
"alphanumeric_space"=>"^[ a-zA-Z0-9\.\,\"\']+$",
"string"=>""
);
# check for required fields
if ($field_required && empty($field_data))
{
$messages[] = "$field_descr is a required field.";
return;
}
# if field type is a string, no need to check regexp:
if ($field_type == "string")
{
$field_ok = true;
}
else
{
# Check the field data against the regexp pattern:
$field_ok = ereg($data_types[$field_type], $field_data);
}
# if field data is bad, add message:
if (!$field_ok)
{
$messages[] = "Please enter a valid $field_descr.";
return;
}
# field data min length checking:
if ($field_ok && $min_length)
{
if (strlen($field_data) < $min_length)
{
$messages[] = "$field_descr is invalid, it should be at least $min_length character(s).";
return;
}
}
# field data max length checking:
if ($field_ok && $max_length)
{
if (strlen($field_data) > $max_length)
{
$messages[] = "$field_descr is invalid, it should be less than $max_length characters.";
return;
}
}
}
