Php 从联系人表单和$POST电子邮件中的复选框中获取值

我的问题是：我试图从复选框中获取值，并通过电子邮件发送它们。现在我得到的只是“无”这个词。在stackoverflow上尝试了许多不同的答案，但到目前为止没有一个有效

<?php
if($_POST)
{
    $to_Email       = "myemail@test.test"; //Replace with recipient email address
    $subject        = 'Poruka'; //Subject line for emails


    //check if its an ajax request, exit if not
    if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {

        //exit script outputting json data
        $output = json_encode(
        array(
            'type'=>'error', 
            'text' => 'Request must come from Ajax'
        ));

    //check $_POST vars are set, exit if any missing
    //if(!isset($_POST["name"]) || !isset($_POST["email"]) || !isset($_POST["telefon"]) || !isset($_POST["objekt"]))
    //{
        //$output = json_encode(array('type'=>'error', 'text' => 'Input fields are empty!'));
        //die($output);

我最终需要的是收到一封包含复选框中的值的电子邮件。到目前为止还没有。其他一切都在形式上起作用。感谢所有回复

尝试序列化您的表单数据，而不是以这种方式将其浓缩

因此，您的post_数据应该如下所示：

post_data = $('form#yourForm').serialize();

---

虽然您创建了变量，但似乎并没有在javascript中发送用户文档：

        //data to be sent to server
        post_data = {
            'name':user_Name,   
            'email':user_Email,   
            'telefon':user_Phone, 
            'objekt':user_Objekt, 
            'kvadratura':user_Kvadratura, 
            'god_izgradnje':user_Izgradnja, 
            'kat_cestica':user_Cestica, 
            'kat_opcina':user_Opcina, 
            'namjena':user_Namjena, 
            'napomena':user_Napomena
        };
        // where is user_Docs??

正如另一个答案所指出的，您应该尝试使用JQuery序列化表单内容。删除您自己的json代码，改用：

    post_data = $('form #form_id').serialize();

---

然后，在PHP脚本中，您应该使用表单中使用的名称获取$\u请求数组中的所有内容。

答案是序列化[link] 这意味着替换这部分代码 //要发送到服务器的数据 post_data={'name'：user_name，'email'：user_email，'telefon'：user_Phone，'objekt'：user_objekt，'kvadratura'：user_kvadratura，'god_izgradnje'：user_Izgradnja，'kat_cestica'：user_cestica，'kat_opcina'：user_opcina，'namjena'：user_namjena，'napomena，'napomena，'napomena'：user_napomena，'dokument[]：user_Docs}

用这个 post_数据=$'formyourForm'。序列化；

---

不完全是这样。我更改了ID并放入了我自己的表单ID，实际上是字段集ID

不知道你所说的var\u dump你的$\u POST是什么意思。也许我不应该说我是一个初学者，我没有一个表单，我在PHP中有一个put var\u dump$\u POST来查看发布了哪些变量。根据标准，只是把它放在后面，字段集应该是表单的一部分。所以你应该把你的字段集放在表单中。当然还没有准备好使用序列化，因为我不知道序列化后下一步该怎么做。现在我非常困惑，因为我认为这是传递值时的一个错误，现在我需要更改我所知甚少的部分代码。非常感谢你们。当你们这么说的时候，我开始考虑代码的这一部分var user_Docs=$input:checkbox[name=dokument]：checked；这篇文章的数据是：{'name'：user'u name，'email'：user'u email，'telefon'：user'u Phone，'objekt'：user'u objekt，'kvadratura'：user'u kvadratura，'god'izgradnje'：user'u Izgradnja，'kat_cestica'：user_cestica，'kat_opcina'：user'opcina，'namjena'：user_namjena，'napomena'：user'napomena}；当你这么说的时候，我开始考虑代码var user_Docs=$input:checkbox[name=dokument]：checked；我甚至不确定我是否在$user\u文档中获得了一个数组，以便发送到任何地方
