Lo que se me va ocurriendo es: poner en el archivo formulario.html el captcha y con el mismo boton que verifica que el texto del capcha ingresado es correcto (y si es correcto), envia el formulario....pero como relacion esto???
codigos:
captchademo.php
<?php
session_start();
if ($_POST['action'] == "checkdata") {
if ($_SESSION['tmptxt'] == $_POST['tmptxt']) {
echo "Bienvenido";
} else {
echo "Intentalo nuevamente";
}
exit;
}
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>CAPTCHA con PHP</title>
<meta name="description" content="CAPTCHA con PHP: ejemplo para demostrar la creacion de Captcha con PHP." />
<link href="styles.css" rel="stylesheet" type="text/css">

<td align="center" class="descdet">

</td>
</tr>
</table>
</body>
</html>
Captcha.php
<?php
session_start();
function randomText($length) {
$pattern = "1234567890abcdefghijklmnopqrstuvwxyz";
for($i=0;$i<$length;$i++) {
$key .= $pattern{rand(0,35)};
}
return $key;
}
$_SESSION['tmptxt'] = randomText(8);
$captcha = imagecreatefromgif("bgcaptcha.gif");
$colText = imagecolorallocate($captcha, 0, 0, 0);
imagestring($captcha, 5, 16, 7, $_SESSION['tmptxt'], $colText);
header("Content-type: image/gif");
imagegif($captcha);
?>
