How to pass a value of a variable from view to controller in codeigniter

问题

using form post method i need to pass a value of numIDto a controller

for example assigning a value to numID inside view,

$numID= 25;

$temp= $_POST[numID];

but its unable to get the exact value. Please help me on this. If have any other alternate way please let me know.

Here is an example of sending info from view to the controller:

View:

<?php echo form_open('invoice'); ?>
<?php echo validation_errors(); ?>
<?php echo form_input('order_num', $this->input->post('order_num')); ?>
<?php echo form_submit('submit','submit'); ?>
<?php echo form_close(); ?>

Controller:

public function invoice()
{
$order = $this->input->post('order_num');
$this->General_Model->get_customer_order($order);
}

Model:

function get_customer_order($order)
{
 . . .
$this->db->where('client_orders.id', $order);
$result = $this->db->get('client_orders');
. . .
}

Note we are using the input name and id as = "order_num" Then we ask the controller to find it as $this->input->post('order_num');
