I trying google recaptcha with this example: www.grupossc.com/pruebas/recaptcha/ejemplo3.php

Everything works fine but after I enter a invalid code, the fields of my form are clear

What can I do to ensure that if I enter a wrong code the fields of my form keep the information

this is the code:
<?php
require_once('recaptchalib.php');
$miFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $miFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}


$captcha_publickey = "xxxxxxxxxxxxxxx";
$captcha_privatekey = "xxxxxxxxxxxxxxx";
$error_captcha=null;

if ($_POST){
   $captcha_respuesta = recaptcha_check_answer ($captcha_privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
$accion = 1;
}

?>
<html>


<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Pagina nueva 1</title>
</head>
<body>
<form name="miforma" enctype="multipart/form-data" method="POST" action="<?php echo $miFormAction; ?>">
test field: <input type="text" name="test" size="27"><br />
<?php echo recaptcha_get_html($captcha_publickey, $error_captcha); ?><br />
<input type="submit" value="Enviar" name="B1">
</form>
</body>

</html>
<?php


if ($accion == 1)
{
  if ($captcha_respuesta->is_valid) 
  {echo "<script type=\"text/javascript\">alert(\"Captcha code is correct\");</script>"; }
 else
 {echo "<script type=\"text/javascript\">alert(\"Captcha code is not correct\");</script>";}	  
}
?>

Uhh... why would you want to keep information when the only human-test element fails?

But that aside, the big-picture concept would be something like this:

1. Client submits form
2. Server copies form data to PHP session
3. Server validates form data
4. Whether or not server validation works, server reloads input value= attributes with data from session.
5. If validation is OK, server processes form data
6. if validation is not OK, server sends form data back to client with the prepopulated form.

Give this a try and see if it works for you.

<?php
require_once('recaptchalib.php');
$miFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $miFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

$captcha_publickey = "xxxxxxxxxxxxxxx";
$captcha_privatekey = "xxxxxxxxxxxxxxx";
$error_captcha=null;

if ($_POST){
   $captcha_respuesta = recaptcha_check_answer ($captcha_privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
$accion = 1;
}

?>
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Pagina nueva 1</title>
</head>
<body>
<form name="miforma" enctype="multipart/form-data" method="POST" action="<?php echo $miFormAction; ?>">
First Name: <input type="text" name="first_name" size="27" value="<?php if(isset($_POST['first_name'])) { echo htmlentities ($_POST['first_name']); }?>"><br />
Last Name: <input type="text" name="last_name" size="27" value="<?php if(isset($_POST['last_name'])) { echo htmlentities ($_POST['last_name']); }?>"><br />
<?php echo recaptcha_get_html($captcha_publickey, $error_captcha); ?><br />
<input type="submit" value="Enviar" name="B1">
</form>
</body>

</html>

<?php
if ($accion == 1)
{
  if ($captcha_respuesta->is_valid) 
  {echo "<script type=\"text/javascript\">alert(\"Captcha code is correct\");</script>"; }
 else
 {echo "<script type=\"text/javascript\">alert(\"Captcha code is not correct\");</script>";}	  
}
?>
