我正在建立一个也使用 reCaptcha 的联系我们页面，但我遇到了一些问题。我填写了联系表格中的所有字段和正确的 reCaptcha 单词，但表格没有提交。我假设这与验证有关，但想知道是否有人能够发现我哪里出错了？
我页面顶部的 PHP 代码如下所示；
<?php include('includes/session.php');
$err = '';
$success = '';
if(isset($_POST["docontact"]) && $_POST["docontact"] == "yes") {
//get form details
$form = new stdClass();
$form->name = sanitizeOne($_POST["name"], "str");
$form->email = sanitizeOne($_POST["email"], "str");
$form->phone = sanitizeOne($_POST["phone"], "str");
$form->mysevenprog = sanitizeOne($_POST["mysevenprog"], "str");
$form->enquiry = sanitizeOne($_POST["enquiry"], "str");
$form->howfindsite = sanitizeOne($_POST["howfindsite"], "str");
//Check for errors (required: name, email, enquiry)
if($form->name == "") {
$err .= '<p class="warning">Please enter your name!</p>';
}
if($form->email == "") {
$err .= '<p class="warning">Please enter your email address!</p>';
}
if($form->enquiry == "") {
$err .= '<p class="warning">Please supply an enquiry message!</p>';
}
//Send Email
if($err == "") {
$mailer = new BlueMailer();
$mailer->AddAddress(Configuration::getVar("developer_email"), Configuration::getVar("admin_email_name"));
include('templates/email/contact-us-admin.php');
if(!$mailer->Send()) {
$err .= "<p>There was an error sending submitting your request!, Please try again later.";
} else {
$success = 'thanks';
}
}
} else {
//Initialise empty variables
$form = new stdClass();
$form->name = "";
$form->email = "";
$form->phone = "";
$form->mysevenprog = "";
$form->enquiry = "";
$form->howfindsite = "";
}
?>
然后在我的页面正文中，我的表格如下；
<?php if($err != "") : ?>
<div class="error">
<?php echo $err; ?>
</div>
<?php endif; ?>
<?php if($success == 'thanks') : ?>
<h3>Thank you for your enquiry</h3>
<p>Your enquiry has been successfully sent. Someone will contact you shortly.</p>
<?php else: ?>
<h3>If you are looking to advertise with us, have some feedback about some of our programming or want to say 'Hi' please use the fields below</h3>
<form name="contactus" id="contactus" method="post" action="<?php echo $_SERVER['SCRIPT_NAME'] ?>">
<ul>
<li><label for="name">Your name: *</label> <input name="name" id="name" class="textbox" style="width: 75%;" type="text" value="<?php echo $form->name ?>" /></li>
<li><label for="email">Email address: *</label> <input name="email" id="email" class="textbox" style="width: 75%;" type="text" value="<?php echo $form->email ?>" /></li>
<li><label for="phone">Telephone:</label> <input name="phone" id="phone" class="textbox" style="width: 75%;" type="text" value="<?php echo $form->phone ?>" /></li>
<li><label for="mysevenprog">My Seven programme</label> <input name="mysevenprog" class="textbox" style="width: 75%;" type="text" value="<?php echo $form->mysevenprog ?>" /></li>
<li><label for="enquiry">Enquiry/Message: *</label> <textarea name="enquiry" class="textarea" rows="5" cols="30" style="width: 75%;" id="enquiry"><?php echo $form->enquiry ?></textarea></li>
<li><label for="howfindsite">How did you find out about our site?</label> <input name="howfindsite" id="howfindsite" class="textbox" style="width: 75%;" type="text" value="<?php echo $form->howfindsite ?>" /></li>
<li>
<?php
require_once('recaptchalib.php');
// Get a key from http://recaptcha.net/api/getkey
$publickey = "";
$privatekey = "";
# the response from reCAPTCHA
$resp = null;
# the error code from reCAPTCHA, if any
$error = null;
# was there a reCAPTCHA response?
if ($_POST["recaptcha_response_field"]) {
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if ($resp->is_valid) {
echo "You got it!";
} else {
# set the error code so that we can display it
$error = $resp->error;
}
}
echo recaptcha_get_html($publickey, $error);
?>
</li>
<li><input type="submit" value="Submit Form" class="button" /></li>
</ul>
<input type="hidden" name="docontact" value="yes" />
</form>
<?php endif; ?>
表单在浏览器中呈现为这样；
<form name="contactus" id="contactus" method="post" action="/contact-us2.php">
<ul>
<li><label for="name">Your name: *</label> <input name="name" id="name" class="textbox" style="width: 75%;" type="text" value="" /></li>
