将数据从 jQuery 传递到 PHP 以用于 ajax 帖子 [英] Pass data from jQuery to PHP for an ajax post

问题描述

您好，我是一个使用 jQuery 和 Ajax 的新手.我正在尝试使用 Jquery POST 方法向服务器提交数据.我传递的数据是一个字符串.现在我无法理解如何传递数据以及如何检索数据.我曾尝试为我的问题搜索文章，但没有找到.我相信我的问题很基本.

Hello I am a newbie working with jQuery and Ajax. I am trying submit data to the server using Jquery POST method. And the data that I am passing is a string. Now I am unable to understand how do I pass the data and how do I retrieve the data. I have tried searching for articles for my problem, but I have found none. I believe my problem is very basic.

if (1)//validateStep(step)
{
if(step==1)
{
var data = document.getElementById('hiddenContact').value;
$.post('/callcenter/admin/postContacts', data);
}
}

现在我将发布 postContacts 操作的代码，这不是什么大事.

Now I'll post the code for my postContacts action, which isn't a big thing.

function postContacts()
{
$this->autoRender = false;
echo '<script>console.log("post contacts");</script>';
}

但我对如何检索数据感到困惑.任何帮助表示赞赏.我正在使用 cakePHP，所以我不得不使用 autoRender=false;这使得视图可选.

But I am confused as to how the data has to be retrieved. Any help is appreciated. I am using cakePHP, so I have had to use autoRender=false; which makes the view optional.

推荐答案

With jQuery post你可以定义一个回调函数，当数据返回时执行:

With jQuery post you can define a callback function which is executed when the data is returned:

$.post('/callcenter/admin/postContacts', data, function(returnedData) {
    // do something here with the returnedData
    console.log(returnedData);
});

data 的格式应该是:

{name: 'value', anotherName: 'another value'}

这等同于 PHP 端的帖子名称，可以像这样在纯 PHP 中访问:

which equates to the post names on the PHP end accessible in plain PHP like this:

echo $_POST['name'];           # prints "value"
echo $_POST['anotherName'];    # print "another value"
