如何从选择多个传递值数组

  • 772

我需要select将multiples中的几个值传递到一个数组中，我需要从列表中选择并全部发送到邮件中。

现在它是这样工作的：

<form>
    <!-- Скрытие поля отправки -->
    <input type="hidden" name="project_name" value="Student Stage">
    <input type="hidden" name="admin_email" value="ss.studentstage@mail.ru">
    <input type="hidden" name="form_subject" value="Заявка с формы поступления">
    <!-- -->



    <select name="Экзамены[]" multiple>
      <option value="Русский язык">Русский язык</option>
      <option value="Математика">Математика</option>
      <option value="Физика">Физика</option>
      <option value="Химия">Химия</option>
      <option value="Биология">Биология</option>
      <option value="География">География</option>
      <option value="Литература">Литература</option>
      <option value="История">История</option>
      <option value="Обществознание">Обществознание</option>
      <option value="Информатика и ИКТ">Информатика и ИКТ</option>
      <option value="Иностранный язык">Иностранный язык</option>
    </select>

    <button>Отправить</button>
</form>

<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="script.js"></script>

这一切都得到验证：

$(document).ready(function() {

    //E-mail Ajax Send
    $("form").submit(function() {
        var th = $(this);
        $.ajax({
            type: "POST",
            url: "mail.php",
            data: th.serialize()
        }).done(function() {
            alert("Ваша заявка была отправлена!\nОжидайте ответа в ближайшее время.");
            setTimeout(function() {
                // Done Functions
                th.trigger("reset");
            }, 1000);
        });
        return false;
    });

});

并通过脚本发送到邮箱：

<?php

$method = $_SERVER['REQUEST_METHOD'];

//Script Foreach
$c = true;
if ( $method === 'POST' ) {

    $project_name = trim($_POST["project_name"]);
    $admin_email  = trim($_POST["admin_email"]);
    $form_subject = trim($_POST["form_subject"]);

    foreach ( $_POST as $key => $value ) {
        if ( $value != "" && $key != "project_name" && $key != "admin_email" && $key != "form_subject" ) {
            $message .= "
            " . ( ($c = !$c) ? '<tr>':'<tr style="background-color: #f8f8f8;">' ) . "
                <td style='padding: 10px; border: #e9e9e9 1px solid;'><b>$key</b></td>
                <td style='padding: 10px; border: #e9e9e9 1px solid;'>$value</td>
            </tr>
            ";
        }
    }
} else if ( $method === 'GET' ) {

    $project_name = trim($_GET["project_name"]);
    $admin_email  = trim($_GET["admin_email"]);
    $form_subject = trim($_GET["form_subject"]);

    foreach ( $_GET as $key => $value ) {
        if ( $value != "" && $key != "project_name" && $key != "admin_email" && $key != "form_subject" ) {
            $message .= "
            " . ( ($c = !$c) ? '<tr>':'<tr style="background-color: #f8f8f8;">' ) . "
                <td style='padding: 10px; border: #e9e9e9 1px solid;'><b>$key</b></td>
                <td style='padding: 10px; border: #e9e9e9 1px solid;'>$value</td>
            </tr>
            ";
        }
    }
}

$message = "<table style='width: 100%;'>$message</table>";

function adopt($text) {
    return '=?UTF-8?B?'.Base64_encode($text).'?=';
}

$headers = "MIME-Version: 1.0" . PHP_EOL .
"Content-Type: text/html; charset=utf-8" . PHP_EOL .
'From: '.adopt($project_name).' <'.$admin_email.'>' . PHP_EOL .
'Reply-To: '.$admin_email.'' . PHP_EOL;

mail($admin_email, adopt($form_subject), $message, $headers );

不是所有的值select都是从那里转移过来的，而只是最后一个选择的。name我正在考虑通过将值添加到数组中[]并编写如下代码来传递值：

<?php
  foreach ($_GET['Экзамены'] as $selectedOption)          
?>

但是我仍然不明白如何将这个数组传输到 mail.php

告诉我如何做到这一点？

PS 除了字段外select，还有几个输入在表单中发送，这里我没有插入

    这是一个如何创建所需对象的示例，字段名称当然是个人喜好问题Экзамены[]，但我认为没有括号是可能的，而不是西里尔文。

    $(document).ready(function() {
    
    //E-mail Ajax Send
    $("form").submit(function(e) {
        e.preventDefault()
        //получаем данные формы
        var formData = new FormData(this)
        //получаем все выделенные элементы списка
        var exams = $('[name="Экзамены[]"]').val();
        //объединяем полученное в один объект
        var object = {
            ...Object.fromEntries(formData), "Экзамены[]":exams
        };
        //конвертируем в json
        var json = JSON.stringify(object);
        console.log(json)
    });
});
