AJAX POST two dimensional array to a Zend controller and recieving it - php

Question

Hi in my view I am creating a two dimentional array in javascript and passting it to the update controller as follows :
Array in Javascript
item[0][0] = null;
item[0][1] = 1;
item[1][0] = 2;
item[1][0] = 3;
alert (item); will show ,1,2,3
Passing it to Zend controller as :
$.ajax({
type: "POST",
url: "admin/navigation/update",
data: item,
success: function(data) {
alert(data);
},
error: function() {
alert("failure");
}
});
return false;
}
How can I receive this from update controller and assign to it a php array as
public function updateAction() {
$data = $this->_request->getPost();
//Code should come here
array(
item1(
array(
value1 = item[0][0] //From javascript array
value2 = item[0][1]
)
)
item2(
array(
value1 = item[1][0]
value2 = item[1][0]
)
)
)
}
I'm a n00b in Zend and any help would be much appriciated :)

Answer 1

Instead of the below code:
$data = $this->_request->getPost();
Use the following code:
$data = $this->_request->getParams();
print_r($data);
This will give you the array as you are sending from javascript.

Answer 2

In your javascript file declare your array:
var item = [[1,2],[3,4]];
Then in your ajax call you should modify the data sent to be JSON. Replace the line
data: item
with
data: {data: JSON.stringify(item)}
Then, in your controller you can decode the data send to get your array:
$data = json_decode($this->getRequest()->getPost("data"));
and you have your array.
