I make a request in ajax at the click of the button passing the id of a product to a controller and it passes to the helper. In the helper, through this id of the product I add it to the cart, but that does not matter much on that issue. I create an array of data in this helper and return it, and the controller returns that array to the request. But when I give an alert in the array so I can see what it upsets me, it returns me a null value and I do not know why that happens.
Ajax request:
function addCartao(product_id){
alert("entrou");
alert(product_id);
$j.ajax({
type: "POST",
url: "<?php echo Mage::getUrl('fol_carousel/ajax/teste') ?>",
data: {
product_id: product_id
},
dataType: 'json',
cache : false,
beforeSend: function () {
alert("beforeSend");
},
success: function (dados) {
alert("success");
alert(dados);
},
complete: function () {
alert("complete");
},
error: function (x,y,z) {
alert("error");
alert(x);
alert(y);
alert(z);
}
});
}
Controller:
$product_id = $this->getRequest()->getPost();
echo json_encode(Mage::helper('fol_carousel/cartao')->addCustom($product_id));
Array created in the helper:
$dados['product_name'] = "teste";
$dados['product_price'] = "2.99";
return $dados;
Every time the ajax request alert is executed, it returns me null.
