Answer 1

Try this code in view page
<select name="customer_id" id="input-sales-person" style="width: 325px;margin-bottom:10px" class="form-control">
<?php foreach($customerData as $customer){ ?>
<option id="temp" value=<?php echo $customer['customer_id']?>><?php echo $customer['customer_name']?></option>
<?php }?>
</select>
<input type="submit" id="noOrder" Onclick="return ConfirmDelete();" value="Submit" class="btn btn-primary">
Use this following script
<script type="text/javascript">
$('#noOrder').on('click', function() {
var temp1=$( "#input-sales-person option:selected" ).val();
var temp2=$( "#input-sales-person option:selected" ).text();
document.cookie = "selectedCustomerId=" +temp1;
document.cookie = "selectedCustomerName=" +temp2;
location="index.php?route=sale/no";
});
</script>
In controller pass the customer_id as $selectedCustomerId=$_COOKIE['selectedCustomerId'];
$selectedCustomerId=$_COOKIE['selectedCustomerId']; /*customer_id=6*/
$queryCustomer = $this->db->query("select customer_id, concat(firstname, ' ',lastname) as name, email from " . DB_PREFIX . "customer where customer_id='".$selectedCustomerId."'");
