Use PHP to Confirm Person, Not Bot

[Stomme poes]

Robots.txt is your friend... Good Bots follow it.

Hi,

One way that I check for bots is:

$UI_Agent = $_SERVER['HTTP_USER_AGENT'];
if(eregi("googlebot", $UI_Agent)) {
   // you have found Google's bot!
   ...
}

HTH,

321web the simple pseudo-code is this:

<?php
session_start();
// Someone submited the form, after 10 sec of first get
if ((isPost('btnSubmit')) && (isset($_SESSION['form'][$PHP_SELF]) && $_SESSION['form'][$PHP_SELF] < time() - 10)) {
  unset($_SESSION['form'][$PHP_SELF]);
  // save / validate form
  if (save()) {
    setMessage('form saved');
    // 302 
    header('Location: /');
    exit;
  }else{
    setError('form has errors');
    // They can fix the form much faster than they can fill it (say 1 -2 sec?)
    $_SESSION['form'][$PHP_SELF] = time() - 9;
  }
} else 
// Someone just loaded the page, load defaults
{
  $_SESSION['form'][$PHP_SELF] = time();
}
?>
