Hey… Do you really think it could be safety?
What if I edit HTML source and send it to server? just using mozilla firebug extension – its the easiest way.

I think all data must be validate on a server side.

Sorry you comment system hates me…

$regs['user_name'] = “^[a-zA-Z][a-zA-Z]*$”;
$regs['user_fname'] = “^[a-zA-Z][a-zA-Z]*$”;
…
…

foreach( $regs as $k => $v )
{
if( ! ereg( $v , $_POST[$k] ) )
{
$errors[$k] = “INVALID…”;
}
}

I think in this area, there oh… about 7368 different ways.

Typically, I go for this model:

$v )
{
if( ! ereg( $v , $_POST[$k] ) )
{
$errors[$k] = “INVALID…”;
}
}

Hmmm… My HTML got removed…

Here’s another try:

> type=”text” name=”c[first_name]” / <
> type=”text” name=”c[last_name]” / <

Hey there. Why not use PHP’s built-in ability to automaticaly create arrays from submitted data?

HTML:

PHP:

$form_data = $_POST['c'];

Using an array, there’s no need to loop through your submitted data to find fields with a prefix.
