我对PHP不太熟悉。在过去，我已经能够使用PHP阅读和修复小问题，但这个问题给我带来了很多麻烦。
我有一个带有两个输入框的表单，一个用于电子邮件，另一个用于消息。
现在，我正在尝试在表单中添加另一个框以验证人工访问是否存在反垃圾邮件
。这是我无法通过验证过程的代码。
//create ramdom numbers
<?php
$num1 = rand(0,9);
$num2 = rand(0,9);
?>
<?php
$error = '';
$email = '';
$comments = '';
$verify = '';
if(isset($_POST['contactus'])) {
$email = $_POST['email'];
$comments = $_POST['comments'];
$app = $_SERVER["REQUEST_URI"];;
if(trim($comments) == '') {
$error = '<div class="error_message">Attention! Please enter your message.</div>';
} else if(trim($email) == '') {
$error = '<div class="error_message">Attention! Please enter a valid email address.</div>';
} else if(!isEmail($email)) {
$error = '<div class="error_message">Attention! You have enter an invalid e-mail address, try again.</div>';
}
//This is where Im having problem. From this point the form doesn't go on.
if(trim($verify) == '') {
error( '<div class="error_message">Attention! Please enter the verification number.</div>');
} else if(trim($verify) != $verify_result) {
error( '<div class="error_message">Attention! The number you entered is incorrect.</div>');
}
if($error == '') {
if(get_magic_quotes_gpc()) {
$comments = stripslashes($comments);
}
$address = "info@myaddress.com";
$e_subject = 'You\'ve been contacted from an app web page ' . $name . '.';
$e_body = "You have been contacted using the app comments box on the above app web page, their additional message is as follows.\r\n\n";
$e_content = "\"$comments\"\r\n\n";
$e_reply = "$name $email";
$msg = $e_body . $e_content . $e_reply;
mail($address, $e_subject, $msg, $app, "From: $email\r\nReply-To: $email\r\nReturn-Path: $email\r\n");
// Email has sent successfully, echo a success page.
echo "<div id='success_page_apps'>";
echo "<h1>Email Sent Successfully.</h1>";
echo "<p>Thank you, your message has been submitted to us.</p>";
echo "</div>";
echo '<input type="button" value="Send Another" onClick="history.go(-1); return (true); ">';
}
}
if(!isset($_POST['contactus']) || $error != '') {
<?php echo $error; ?>
<fieldset id="contact_apps">
<form method="post" action="#ContactForm">
<label for="email" accesskey="E"><span class="required"></span> Email</label>
<input name="email" type="text" id="email" size="33" value="<?php echo$email;?>"/>
<textarea name="comments" cols="50" rows="15" id="comments"><?php echo$comments;?></textarea>
//This is the 'Are you human?' message
<p><span class="required">*</span> Are you human?</p>
<label class="numbersq" for='verify' accesskey='V'><?php echo $num1; ?> + <?php echo $num2; ?> =</label>
<input class="numbersa" name="verify" type="text" id="verify" size="4" value=""/>
<input name="verify_result" type="hidden" size="4" value="<?php echo $num1+$num2; ?>" /><br />
<input name="contactus" type="submit" class="send" id="contactus" >
</form>
</fieldset>
}
?>
请注意“你是否是人”信息以及我在脚本中的条件，我认为我做错了。

您忘记从表单中提取验证值...而且您还有其他一些简单的错误，我已经解决过了。
