我有一个使用 PHP 创建的表单（我对它的理解几乎没有我想要的那么多） - 我不久前使用在线教程制作了表单，不太记得来自哪里，也找不到了，但是表格可以正常工作，所以我很满意。
唯一的事情是，我需要在我的表单中添加复选框，它们不需要验证（如果没有选中，表单仍然可以发送，如果它们都被选中，表单仍然可以发送..）
我需要做的是发回给我的电子邮件，让我知道哪些复选框被勾选了。
这是我的 HTML/PHP 页面：
<!--Contact Form Section -->
<div id="contact-form" class="clearfix">
<?php
//init variables
$cf = array();
$sr = false;
if(isset($_SESSION['cf_returndata'])){
$cf = $_SESSION['cf_returndata'];
$sr = true;
}
?>
<form method="post" action="process.php">
<input type="email" id="email" name="email" placeholder="Your e-mail" value=" <?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['email'] : '' ?>" required="required" />
<input type="text" id="name" name="name" placeholder="Your name" value="<?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['name'] : '' ?>" required="required" />
<textarea id="message" name="message" placeholder="Your message..." required="required" data-minlength="20"><?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['message'] : '' ?></textarea>
<span id="loading"></span>
<input type="submit" value=" " id="submit-button" />
<ul id="errors" class="<?php echo ($sr && !$cf['form_ok']) ? 'visible' : ''; ?>">
<li id="info">There is a problem:</li>
<?php
if(isset($cf['errors']) && count($cf['errors']) > 0) :
foreach($cf['errors'] as $error) :
?>
<li><?php echo $error ?></li>
<?php
endforeach;
endif;
?>
</ul>
<p id="success" class="<?php echo ($sr && $cf['form_ok']) ? 'visible' : ''; ?>">Thanks for your message!</p>
</div>
</form>
<?php unset($_SESSION['cf_returndata']); ?>
<!--End Contact Form Section -->
这是我的过程PHP文档：
<?php
if( isset($_POST) ){
//form validation vars
$formok = true;
$errors = array();
//submission data
$ipaddress = $_SERVER['REMOTE_ADDR'];
$date = date('d/m/Y');
$time = date('H:i:s');
//form data
$name = $_POST['name'];
$email = $_POST['email'];
$telephone = $_POST['telephone'];
$enquiry = $_POST['enquiry'];
$message = $_POST['message'];
//validate form data
//validate name is not empty
if(empty($name)){
$formok = false;
$errors[] = "You have not entered a name";
}
//validate email address is not empty
if(empty($email)){
$formok = false;
$errors[] = "You have not entered an email address";
//validate email address is valid
}elseif(!filter_var($email, FILTER_VALIDATE_EMAIL)){
$formok = false;
$errors[] = "You have not entered a valid email address";
}
//validate message is not empty
if(empty($message)){
$formok = false;
$errors[] = "You have not entered a message";
}
//validate message is greater than 20 characters
elseif(strlen($message) < 20){
$formok = false;
$errors[] = "Your message must be greater than 20 characters";
}
//send email if all is ok
if($formok){
$headers = "From: Goldie Locks online contact form" . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$emailbody = "<p>You have received a new message from the enquiries form on your website.</p>
<p><strong>Name: </strong> {$name} </p>
<p><strong>Email Address: </strong> {$email} </p>
<p><strong>Message: </strong> {$message} </p>
<p>This message was sent from the IP Address: {$ipaddress} on {$date} at {$time}</p>";
mail("MY EMAIL!","New Enquiry",$emailbody,$headers);
}
//what we need to return back to our form
$returndata = array(
'posted_form_data' => array(
'name' => $name,
'email' => $email,
'telephone' => $telephone,
'enquiry' => $enquiry,
'message' => $message
),
'form_ok' => $formok,
'errors' => $errors
);
//if this is not an ajax request
if(empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) !== 'xmlhttprequest'){
//set session variables
session_start();
$_SESSION['cf_returndata'] = $returndata;
//redirect back to form
header('location: ' . $_SERVER['HTTP_REFERER']);
}
}
从 html 代码中可以看出，我取出了 PHP 的一些功能，但将它们留在了 PHP 进程中（例如查询类型和电话号码），因为我完全不确定什么会破坏什么。
我需要做的就是在 html/php 文档中添加复选框（准确地说是 5 个），并在有人填写页面时将勾选的复选框显示在我收到的电子邮件中。
希望这对于具有 PHP 知识的人来说是一件容易的事，但遗憾的是我知道的很少。希望有人可以提供帮助，如果您需要更多信息，请发表评论，我会尽力而为。
谢谢
