没有从复选框数组中获取值

表格代码如下：

<form method="post" action="sendeform.php">
         <p><label for="company">Company:</label> <input type="text" class="form-control" name="company" id="company" tabindex="1" /></p>

            <p><label for="doors">Number of windows / Doors:</label> <input type="text" class="form-control" name="doors" id="doors" tabindex="6" /></p>

 <p><label for="hear">How did you hear about our company?</label> <textarea  class="form-control" name="hear" id="hear" cols="12" rows="6" tabindex="7"></textarea></p>

        <p><input name="estimatesubmit" type="submit" id="estimatesubmit" class="submit" value="Send" tabindex="9" /></p>

</form>

这是运行表单的 PHP：

<?php


if(isset($_POST['submit'])){//to run PHP script on submit
if(!empty($_POST['check_list'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected){
echo $selected."</br>";
}}}




$company = filter_var($_POST['company'], FILTER_SANITIZE_STRING);
$firstname = filter_var($_POST['firstname'], FILTER_SANITIZE_STRING);
$lastname = filter_var($_POST['lastname'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
$phone = filter_var($_POST['phone'], FILTER_SANITIZE_STRING);
$street = filter_var($_POST['street'], FILTER_SANITIZE_STRING);
$city = filter_var($_POST['city'], FILTER_SANITIZE_STRING);
$state = filter_var($_POST['state'], FILTER_SANITIZE_STRING);
$zip = filter_var($_POST['zip'], FILTER_SANITIZE_STRING);
$doors = filter_var($_POST['doors'], FILTER_SANITIZE_STRING);
$hear = filter_var($_POST['hear'], FILTER_SANITIZE_STRING);
$info = filter_var($_POST['info'], FILTER_SANITIZE_STRING);

$site_owners_email = 'email@gmail.com'; // Replace this with your own email address
$site_owners_name = 'Client Name'; // replace with your name
$site_owners_name_from = 'Free Estimate Submission';

if (strlen($firstname) < 2) {
    $error['firstname'] = "Please enter your first name";
}

if (strlen($lastname) < 2) {
    $error['lastname'] = "Please enter your last name";
}

if (!preg_match('/^[a-z0-9&\'\.\-_\+]+@[a-z0-9\-]+\.([a-z0-9\-]+\.)*+[a-z]{2}/is', $email)) {
    $error['email'] = "Please enter a valid email address";
}

if (strlen($phone) < 3) {
    $error['phone'] = "Please enter your phone number.";
}

if (!$error) {

    require_once('phpMailer/class.phpmailer.php');
    $mail = new PHPMailer();

    $mail->From = $email;
    $mail->FromName = $site_owners_name_from;
    $mail->Subject = "Form Submission";
    $mail->AddAddress($site_owners_email, $site_owners_name);
    $mail->IsHTML(true);
    $mail->Body = 'The estimate form on your website, 3Msecurityfilm.com, has been filled out.'. '<br/><br/>'. '<b>Company:</b> '. $company . '<br/><b>First Name:</b> '. $firstname .

'<br/><b>How did you hear about our company?</b> '. $hear . '<br/><b>Additional Information:</b> '. $info;



    $mail->Send();

    echo "<div class='alert alert-success'  role='alert'>Thanks " . $firstname . ". Your message has been sent.</div>";

} # end if no error
else {

    $response = (isset($error['firstname'])) ? "<div class='alert alert-danger'  role='alert'>" . $error['firstname'] . "</div> \n" : null;
    $response .= (isset($error['email'])) ? "<div class='alert alert-danger'  role='alert'>" . $error['email'] . "</div> \n" : null;
    $response .= (isset($error['phone'])) ? "<div class='alert alert-danger'  role='alert'>" . $error['phone'] . "</div>" : null;

    echo $response;

代码

// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected){
    echo $selected."</br>";
}

对我来说似乎有点奇怪。这显示所有值都可以，但不存储它们。在此循环之后，$selected 将具有数组的最后一个元素作为值。因此，没有任何内容存储，正如评论所暗示的那样。

在邮件正文中，您使用的是$selected。这具有来自数组的任意值，或者如果数组为空则未初始化。你可以做的是implode(', ', $_POST['check_list'])，它用逗号连接数组的元素（即[4,7,8]变成"4, 7, 8"）。

如果这仍然不起作用，则该值未正确传递到 $_POST。您可以在文件顶部执行var_dump($_POST) 以查看check_list 值是否实际出现在那里。如果需要帮助，可以在问题中包含该 var 转储的输出。
