使用 jQuery 和 PHP 序列化和提交表单 [英] Serializing and submitting a form with jQuery and PHP

问题描述

我正在尝试使用 jQuery 发送表单数据.但是，数据不会到达服务器.你能告诉我我做错了什么吗?

I'm trying to send a form's data using jQuery. However, data does not reach the server. Can you please tell me what I'm doing wrong?

我的 HTML 表单:

My HTML form:

<form id="contactForm" name="contactForm" method="post">
    <input type="text" name="nume" size="40" placeholder="Nume">
    <input type="text" name="telefon" size="40" placeholder="Telefon">
    <input type="text" name="email" size="40" placeholder="Email">
    <textarea name="comentarii" cols="36" rows="5" placeholder="Message"></textarea> 
    <input id="submitBtn" type="submit" name="submit" value="Trimite">
</form>

JavaScript(与上述表单在同一个文件中):

JavaScript (in the same file as the above form):

<script type="text/javascript">
    $(document).ready(function(e) {

        $("#contactForm").submit(function() {
            $.post("getcontact.php", $("#contactForm").serialize())
            // Serialization looks good: name=textInNameInput&&telefon=textInPhoneInput etc
            .done(function(data) {
                if (data.trim().length > 0) {
                    $("#sent").text("Error");   
                } else {
                    $("#sent").text("Success");
                }
            });

            return false;
        })
    });
</script>

服务器端 PHP (/getcontact.php):

$nume = $_REQUEST["nume"]; // $nume contains no data. Also tried $_POST
$email = $_REQUEST["email"];
$telefon = $_REQUEST["telefon"];
$comentarii = $_REQUEST["comentarii"];

你能告诉我我做错了什么吗?

Can you please tell me what I am doing wrong?

检查 var_dump($_POST) 并返回一个空数组.

Checked var_dump($_POST) and it returned an empty array.

奇怪的是，在我的本地机器上测试的相同代码运行良好.如果我将文件上传到我的托管空间，它就会停止工作.我尝试在不使用 jQuery 的情况下做一个老式的表单，所有数据都是正确的.

The weird thing is that the same code tested on my local machine works fine. If I upload the files on my hosting space it stops working. I tried doing an old-fashioned form without using jQuery and all data was correct.

我不明白这会是一个服务器配置问题.有什么想法吗?

I don't see how this would be a server configuration problem. Any ideas?

谢谢！

推荐答案

可以使用这个功能

var datastring = $("#contactForm").serialize();
$.ajax({
    type: "POST",
    url: "your url.php",
    data: datastring,
    dataType: "json",
    success: function(data) {
        //var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
        // do what ever you want with the server response
    },
    error: function() {
        alert('error handling here');
    }
});

返回类型为json

我使用 event.preventDefault 来防止浏览器在这种情况下被提交.

I use event.preventDefault to prevent the browser getting submitted in such scenarios.

为答案添加更多数据.

dataType: "jsonp" 如果是跨域调用.

beforeSend://这是一个请求前回调函数

beforeSend: // this is a pre-request call back function

complete://请求结束后要调用的函数.所以不管成功还是错误都必须执行的代码可以放在这里

complete: // a function to be called after the request ends.so code that has to be executed regardless of success or error can go here

async://默认情况下，所有请求都是异步发送的

async: // by default, all requests are sent asynchronously

cache://默认为 true.如果设置为 false，它将强制请求的页面不被浏览器缓存.

cache: // by default true. If set to false, it will force requested pages not to be cached by the browser.
