通过ajax到PHP的多维数组-MultidimensionalArraysviaajaxtoPHP

Ok seriously struggling here. I am having some problems trying to send a multdimensional array to PHP via ajax. Here's what I have been trying:

好认真在这里挣扎。我试图通过ajax向PHP发送多维数组时遇到一些问题。这是我一直在尝试的:

To simplify rather than copy paste a wall of code:

为了简化而不是复制粘贴代码墙:

    peoplearray[0]  =  [name] => 'john'
                       [age]  => '28'
                       [sex]  => 'Male'
    peoplearray[1]  =  [name] => 'julie'
                       [age]  => '20'
                       [sex]  => 'Female'

    main_array['item'] = 'x';
    main_array['something'] = 'x';
    main_array['another'] = 'x';

I want to get this to php via post. I figured I may aswell just join them together as I am multidimensional anyway thus :

我希望通过帖子将其发送到php。我想我也可以将它们加在一起,因为我是多维的,因此:

    main_array['peoplearray'] = peoplearray;

now to do the ajax:

现在要做ajax:

// var data = JSON.stringify(main_array);

var send = $.ajax({
        type: "POST",
        cache: false,
        url: "theurl",
        data: {data:main_array} //I do change this `main_array` when using the above stringify!
});


send.done(function(msg) {
console.log(msg);
})

in PHP I am just doing the following right now:

在PHP中,我现在正在执行以下操作:

$data= $_POST['data'];
print_r($data);

in firebug: (an empty string)

在萤火虫:(一个空字符串)

when I have the var data = JSON.stringify(main_array); uncommented I get the following: [][

当我有var data = JSON.stringify(main_array);取消注释我得到以下内容:[] [

if i add $data = json_decode($_POST['data']); to the php I get:

如果我添加$ data = json_decode($ _ POST ['data']);我得到的PHP:

Array ( )

Basically the main_array I realise does not need to be an array and so I can get that stuff across no problem but what I need to do is get the peoplearray over so that I can do some foreach etc... with it in php. Any help would be much appreciated I am sure I am just being stupid!

基本上我认识的main_array不需要是一个数组,所以我可以得到那些东西没有问题,但我需要做的是让人们发布,以便我可以做一些foreach等...用它在PHP中。任何帮助将不胜感激我相信我只是愚蠢!

EDIT: The reasoning behind this is that peoplearray could have 0 or 100 entries so I just need to get it to php so I can foreach it to do the DB inputs. If there is a better approach I would be very grateful to hear it as I am still pretty new to this.

编辑:这背后的原因是peoplearray可能有0或100个条目,所以我只需要将它转换为php,这样我就可以预先做它来进行数据库输入。如果有一个更好的方法,我会非常感激听到它,因为我仍然是新手。

EDIT: Thanks to Nicola's answer everything is passing fine except the important part which is mainarry.peoplearray - it is not appearing in the the return console.log and I cant access it in PHP. Any solutions on this or do I have to put the foreach intelligence in the Javascript and just send everything individually?

编辑:感谢Nicola的回答一切正常,除了mainarry.peoplearray的重要部分 - 它没有出现在return console.log中,我无法在PHP中访问它。任何解决方案或我是否必须将foreach智能放在Javascript中并单独发送所有内容?

2 个解决方案

main_array['peoplearray'] = peoplearray;

main_array.peoplearray = peoplearray;

var main_array = {};

var send = $.ajax({
        type: "POST",
        dataType: "json",
        cache: false,
        url: "theurl",
        data: {data:main_array} 
});

header('Content-type: application/json');
$data= $_POST['data'];
echo json_encode($data);

var send = $.ajax({
        type: "POST",
        dataType: "json",
        cache: false,
        url: "theurl",
        data: {data:main_array, people:peoplearray} 
});

echo json_encode($people); //or whatever var name it is stored as in the php 

send.done(function(msg) {
console.log(msg);
})
