How to send an Array via POST to a PHP controller

Question

I need to pass an array via POST to my PHP controller, the only way I have in mind is not to pass an array, but to pass the information through a separator (, |), but I didn’t want to keep giving it explodes on the other side (Controller).

At the moment I’m doing the following, Javascript:

 var listaEnvioArray = new Array();
 var item = new Array();
 item["id"] = 1;
 item["descricao"] = "teste";
 listaEnvioArray.push(item);

 $.post(basepath + "perfil/meuController", {
    array : listaEnvioArray
    }, function(dados) {    
        // TODO ação
    });

In my controller I am recovering this way(Codeigniter):

$dados['array'] = $this->input->post('array');

But the same comes empty here.

Answer 1

The problem is in Javascript here:

var item = new Array();
item["id"] = 1;
item["descricao"] = "teste";

You defined a array but is using as if it were an object/hash. Do so:

var item = {};
item["id"] = 1;
item["descricao"] = "teste";

Or so:

var item = { id: 1, descricao: "teste" };

Array Javascript is not equal to PHP. You cannot use alpha-numeric keys. Only objects can have properties that are text ("id", "Description"). Javascript, Arrays only have numeric keys, and we cannot interfere with them freely as we can in PHP.

Answer 2

I would pass the data as object itself, and recover them in PHP with the function json_decode() transforming them into a php array.
