codeigniter: send a multidimensional array from view to controller via ajax

Question

I have a php multidimensional array:

$array[0] = array('Jack','[email protected]');
$array[1] = array('one'=>'test1','two'=>'test2'); //unknown data limit 
it could be 5 or 10 or 100 items consider the second array as purchased products.

I want to send this array $array to the controller from the view. I tried:

$newArray = json_encode($array);
$.post('<?=base_url()?>controller/function/<?=$newArray ?>').done(function (res) {
        alert(res);
    });

But I get a security error can't send '[' or '{' in a url. and when I just echo $array in the post it won't work becuase the result will be: "Array".

So the question now is how to send this multidimensional array from view to controller in codeigniter?

Works fine thanks. I'm still not familiar with codeigniter and tried this way without json_encode but didn't work. You can add it as an answer $.post('<?=base_url()?>/controller/function',{t:<?=newArray?>}) — PHP User

add this code in your view

<script>
   var myJsonString = JSON.stringify(yourArray);
   var url="<?php echo base_url(); ?>/controller/show_json";
   $.ajax({
     type: "POST",
     url: url,
     dataType: 'json',
     data: myJsonString,
     success: function(data){
             console.log(data); 
          }
      });
</script>

add this function on your controllers

function show_json()
{
   print_r($_POST);
}

Use urlencode() (or encodeURIComponent() in javascript) in the view:

$newArray = urlencode(json_encode($array));

OR:

$.post('<?=base_url()?>controller/function/'+encodeURIComponent('<?=$newArray ?>')).done(function (res) {
        alert(res);
    });

and

$json = urldecode($urlencodedjson);

on the receiver side.

In the view:

$newArray = json_encode($array)
$.post('<?=base_url()?>/controller/function',{t:<?=$newArray?>}).done(function (res) {
     alert(res);
});

In the controller:

$arr1 = $_POST['t'][0];
$arr1 = $_POST['t'][1];
