ajax or database not working - php

Question

I have been struggling for days. I am doing ajax callback by assigning an input field but I am unable to too. Below is the code:
Script
$('[name="acccode[]"]').each(function(idx,val){
var acccode = $('[name="acccode[]"]').eq(idx).val();
console.log(acccode);
$.ajax({
url : "<?php echo base_url(); ?>readacccode",
type: "POST",
data:"Acc_Code="+acccode,
dataType: "JSON",
success: function(data)
{
$.each(data.results,function(idx,val){
console.log(val);
$('[name="accname[]"]').val(val);
});
},
error: function (data)
{
swal("Oops", "We couldn't connect to the server!", "error");
}
});
});
I am successfully able to get each acc code. But not the name.
Here is the Controller code:
public function readacccode()
{
if (!$this->ion_auth->logged_in() || $this->ion_auth->is_store())
{
redirect('account/login');
}
$acccode = $this->input->post('acccode');
$data['results']=$this->Setting->get_acccode($acccode);
echo json_encode($data);
}
it is getting the acc name where the acc code matches.
Please advise.

Thanks, everyone the problem is resolved. For those wanting to know here is the thing I change.
public function readacccode()
{
if (!$this->ion_auth->logged_in() || $this->ion_auth->is_store())
{
redirect('account/login');
}
$acccode = $this->input->post('Acc_Code'); //All I did is replace acccode to Acc_Code
$data['results']=$this->Setting->get_acccode($acccode);
echo json_encode($data);
}
