php - 使用 PHP 接收选择多个值

Question

我正在尝试在引导程序中使用 select multiple 接收多个选定的值。我也尝试使用数组，因为我在互联网上找到了几个与接收选择框的值相关的解决方案，但它仍然无法正常工作。它还发送仅写入的数组字，没有值。

html代码

<form action="send-mail.php" method="POST" class="contact_box">
                            <div class="panel-body">
                                <div class="form-group">
                                    <div class="input-group">
                                        <span class="input-group-addon"><i class="glyphicon glyphicon-user blue"></i></span>
                                        <input type="text" name="InputName" placeholder="Full Name*" class="form-control" required>
                                    </div>
                                </div>
                                <div class="form-group">
                                    <div class="input-group">

                                    </div>
                                </div>

                                           <select multiple class="form-control" name="Services[]" placeholder="Services Required*" required size="3">
                                             <option value="s1">1</option>
                                             <option value="s2">2</option>
                                             <option value="s3">3</option>

                                           </select>

                                    </div>
                                </div>

                                        <textarea name="InputMessage" rows="6" placeholder="Message or Comment*" class="form-control" type="text" required></textarea>

                                <div class="">
                                <button type="submit" class="btn btn-default pull-right">Send <span class="glyphicon glyphicon-send"></span></button>

                            </div>
                    </form>

PHP 代码

<?php
$InputName = $_POST['InputName'];
$InputEmail = $_POST['InputEmail'];
$InputCno = $_POST['InputCno'];
$Services = $_POST['Services'];
$InputMessage = $_POST['InputMessage'];
$formcontent=" From: $InputName \n Email Address: $InputEmail \n Contact Number: $InputCno \n Services Required: $Services \n Message: $InputMessage ";
$recipient = "[e-mail]";
$subject = "Enquiry";
$mailheader = "From: $InputEmail \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
header('Location: thank-you.html');
echo "Thank You!" . " -" . "<a href='index.html' style='text-decoration:none;color:#ff0099;'> Return Home</a>";
?>

请帮助接收选择框中的所有选定值。

感谢您的时间。

您的问题是您想访问数组内容，而这不是通过 echo 完成的，

您可以使用 implode 函数将数组内容转换为字符串

$Services = implode(",",$_POST['Services']);
