frist you need this

<input type="hidden" value="<?php echo $duration->visaId;?>" id="visaId"/>

var visaId = $("#visaId").val();
$(document).ready(function () {
$.ajax({
type: "POST",
url: "visa/ViewVisaPopup",
data: {visaId: visaId,visaBr: visaBr},
success: function (data) {
$('.ViewPkgPopup').html(data);
}
});
});


}
thand Add this code in your controller

{
$visaId = $this->input->post("visaId");
//$visabanner = $this->input->post("visaBr");
