From Wordpress plugin data is not getting inserted into custom table - wordpress

Question

I have created a plugin to insert and fetch records. When I save record, record is getting saved from localhost but when I try it on online server it is not getting saved. Here is what I am trying to do.
function data_custom_ajax(){
global $wpdb;
$tbl = "tripplan";
$table_name=$wpdb->prefix . $tbl;
$custom_val = $_POST['text'];
$totaltime = $_COOKIE['totalduration'];
$totaldistance = $_COOKIE['totaldistance'];
$origin_address = $custom_val['originaddress'];
$end_address = $custom_val['destinationaddress'];
$waypoints = $custom_val['waypts'];
$wpdb->insert($table_name,
array(
'startpoint' => $origin_address,
'endpoint' => $end_address,
'waypoints' => json_encode($waypoints),
'totaldistance' => $totaldistance,
'totalduration' => $totaltime
),
array('%s','%s','%s','%f','%f')
);
echo "data has been saved";
}

After lot of reading and debugging I got to know the problem. My cookie was not getting saved correctly. Even though it was working on localhost, it was not working on website. After reading this [PHP cannot read javascript cookies and then after I modified my cookie while saving.
I was setting cookie like this and it was not working-
document.cookie="cookiename="+value
after setting this way it worked -
document.cookie = 'cookiename='+value+'; path=/'
