如何从jquery serializearray()中检索$ _POST变量 [英] How to retrieve $_POST variable from jquery serializearray()

问题描述

从jquery serializeArray();检索$ _POST数据时遇到问题.我尝试for循环$ _POST以获取数据，但失败了.

I have a problem in retrieving the $_POST data from jquery serializeArray();. I tried to for loop the $_POST to get the data but failed.

这是我的JavaScript代码:

This is my JavaScript code:

    function update_cart(){
    var fields = $(':input').serializeArray();
    console.log(fields);
    var url = "update_cart.php";
    $.post(url, {fields:fields}, function(data) {
         alert(data);
    }, "html");
        return false;
}

在我的PHP代码中:

var_dump($_POST);

结果是这样的:

array(1) {["fields"]=> string(15) "[object Object]"}

那么，任何人都可以教我如何访问$ _POST数据吗?

So, can anyone please teach me how to access the $_POST data?

推荐答案

您无需嵌套序列化的对象；这似乎是导致错误的原因.只需将您的帖子通话设置为:

You don't need to nest your serialized object; that seems to be what's causing the error. Just set your post call to:

$.post(url, fields, function(data) {
     alert(data);
     }, "html");

那应该起作用；您可能还希望从使用serializeArray更改为使用serialize.

That should work; you might also want to change from using serializeArray to using serialize.

正确配置后，如果您具备以下条件:

Once this is properly configured, if you have:

<input name="foo" value="bar" />

它可以通过以下方式访问:

It can be accessed as:

 $_POST["foo"]; //bar
