我正在尝试使用php库为google的reCAPTCHA向外部网址发布操作,如下所示:
<?php
require_once('recaptchalib.php');
$publickey = "***";
$privatekey = "***";
$resp = null;
$error = null;
if ($_POST["recaptcha_response_field"]) {
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if (!$resp->is_valid) {
// What happens when the CAPTCHA was entered incorrectly
die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
"(reCAPTCHA said: " . $resp->error . ")");
} else {
// Your code here to handle a successful verification
}
}
?>
<form action="https://www.salesforce.com" method="POST">

如何使用同一页面使用reCaptcha验证表单,如果正确的话 将用户发送到外部操作? 我也试过这个:
<?php
require_once('recaptchalib.php');
$publickey = "***";
$privatekey = "***";
$resp = null;
$error = null;
if ($_POST["recaptcha_response_field"]) {
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if ($resp->is_valid) {
$action = 'https://www.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8';
} else {
echo $error;
$error = $resp->error;
}
}
?>
<form action="<?php echo $action; ?>" method="POST">
</form>
