PHP 发送脚本 -- 复选框验证

好吧，这是我的朋友，最终和工作版本。

经过测试并正常工作，完成：

索取手册：是
或
索取手册：您的电子邮件中没有消息，
另外，我还在最后添加了回声"谢谢，您的信息已发送..."选项。

要使用的 PHP：

<?php
//$www = '';    
$email = '';
$nameis = '';
$phone = '';
$bestime = '';
//$address = '';
$origin = '';
$destination = '';
$msg = '';
$brochure = '';
function getIp()
{
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
    $ip_address=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
if (!isset($ip_address)){
        if (isset($_SERVER['REMOTE_ADDR'])) 
        $ip_address=$_SERVER['REMOTE_ADDR'];
}
return $ip_address;
}
if(isset($_POST['brochure'])){
$brochure = "YES";
} 
else {
$brochure = "NO";
}

//taking info about date, IP and user agent
$timestamp = date("Y-m-d H:i:s");
$ip   = getIp();
$host = gethostbyaddr($ip); 
$user_agent = $_SERVER["HTTP_USER_AGENT"];

//taking the data from form 
//$www = addslashes(trim($_POST['www']));   
$email = addslashes(trim($_POST['email']));
$nameis = addslashes(trim($_POST['nameis']));
$phone = addslashes(trim($_POST['phone']));
$bestime = addslashes(trim($_POST['bestime']));
//$address = addslashes(trim($_POST['address']));
$origin = addslashes(trim($_POST['origin']));
$destination = addslashes(trim($_POST['destination']));
$msg = addslashes(trim($_POST['msg']));

$headers .= "Content-type: text/html; charset=utf-8'n";
$headers .= "Content-Transfer-Encoding: quoted-printable'n";
$headers .= "From: $email'n";
$content = 'Name: '.$nameis.'<br>'.
'E-mail: '.$email.'<br>'.
'Phone: '.$phone.'<br>'.
'Message: '.$msg.'<br>'.
'Best Time to Call: '.$bestime.'<br>'.
'Origin: '.$origin.'<br>'.
'Destination: '.$destination.'<br>'.
'Requested Brochure: '.$brochure.'<br>'.
'Time: '.$timestamp.'<br>'.
'IP: '.$host.'<br>'.
'User agent: '.$user_agent;

//sending mail
mail("your_email@example.com","Los Altos, CA Landing Page Contact", $content, $headers);
echo "Thank you, your message has been sent. We will contact you as soon as possible.";
?>

我设置它的方式是我使用POSTed值中的isset，$brochure赋值为变量，如果设置，则变量等于"YES"，如果未设置，则同一变量等于"NO"。

(下面的代码被添加到PHP中，而其他一些代码被删除(

if(isset($_POST['brochure'])){
$brochure = "YES";
} 
else {
$brochure = "NO";
}

之前发生的语法错误是，您对复选框值使用了addslashes和trim，这造成了严重破坏。

脚本存在多个问题：

• 表单没有提交按钮。需要将表单输入发送到服务器。
• 您不会在脚本中的任何位置验证表单。这就是它产生不必要的错误的原因。
• 在你的代码中，你有很多这样的 - $email = addslashes(trim($_POST['email']));但你不接受任何地方的输入。由于输入字段不存在，如果您尝试回显它们，PHP 将抛出Undefined index错误。

.HTML：

<form id="proForm" action="send-form.php" method="post" >
<tr>
<th class="label"><label for="brochure">Request Brochures</label></td>
<td class="field">
Email: <input type="text" name="email">
Phone: <input type="text" name="phone">
Bestime: <input type="text" name="bestime">
Origin: <input type="text" name="origin">
Destination: <input type="text" name="destination">
Message: <textarea name="msg">Input message</textarea>
<input type="checkbox" name="brochure" value="Yes" />
<input type="submit" name="submitButton"/>
</form>

.PHP：

if(isset($_POST['submitButton'])){
//the form was submited, process the inputs below!
}

希望这有帮助！

代码的第一行缺少右括号：

您的代码：

if(isset($_POST['brochure']){
// Requested Brochures
}

应该是：

if(isset($_POST['brochure'])){ //Closing bracket for if added
// Requested Brochures
}

干杯！

解释：

发生的情况是，仅当选中该复选框时，才会设置$_POST['brochure']。在您的代码中，您将其用作：

if(isset($_POST['brochure'])){
 $brochure_checked = $_POST['brochure'];} 
else {
 $brochure_not_checked = $_POST['brochure'];
}

如果设置了小册子字段，您将获得该值。但是看看你的 else 条件，你正在分配不存在的值。这个语句$brochure = addslashes(trim($_POST['brochure']));现在正在尝试修剪不存在的值。检查编辑的代码。希望它有效！我在编辑部分使用了注释。
