Send array in ajax query

I'm trying to send an array from JavaScript to PHP with the $.post() method of Jquery.

I've tried jQuery.serialize(), jQuery.serializeArray(), JSON.stringify() and all of them didn't work.

Here is my code:

$.post("ajax/"+action+"_xml.php",{'array': array},function(data){console.log(data);});

the array looks like this :

array["type"]
array["vars"]["name"]
array["vars"]["email"]

array["vars"] has more than 2 elements.

The result in my php $_POST variable is an empty array (length 0).

I would suggest the following structure on the data which you pass:

Javascript:

var DTO = { 
    type: [1,2,3],
    vars: {  
        name: 'foo',
        email: '[email protected]'
    }
};

var stringifiedData = JSON.stringify(DTO); 

// will result in:
//{"type":[1,2,3],"vars":{"name":"foo","email":"[email protected]"}} 

$.post("ajax/"+action+"_xml.php",{'DTO': stringifiedData },function(data){
    console.log(data);
});

PHP:

header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Content-type: application/json');

$DTO = $_POST['DTO'];

if(isset($DTO))
{
    $assocResult = json_decode($DTO, true);
    var_dump($assocResult); //do stuff with $assocResult here
}

Passing true as the second argument to json_decode will make it return an associative array.

You need to turn your javascript array into a string, as that's all the post() method accepts. Most people do this by converting their array to JSON.

I'm not sure whether you can post an array like that.

Splitting it should work just fine:

$.post("ajax/"+action+"_xml.php",{'type': array["type"], 'name' : array["vars"]["name"],...},function(data){console.log(data);});
