Append square brackets ('[]') to your input names and it will turn them into arrays. That way you can do something like the following:
Lets suppose your $_SESSION['openorders'] has the following array:
Code:
array(
0 => array('orderid' => 1, 'prodid' => 57, 'name' => 'product_num_1'),
1 => array('orderid' => 2, 'prodid' => 65, 'name' => 'product_num_2')
)
In your view, generate your hidden input fields like this:
Code:
foreach($_SESSION['openorders'] as $values)
{
$orderid = $values['orderid'];
$prodid = $values['prodid'];
$name = $values['name'];
echo form_hidden('orderid[]', $orderid);
// ...generates <input type="hidden" name="orderid[]" value="1" />
// notice the '[]' at the end of order id, this will pair it with other orderid inputs and make it an array of values.
echo form_hidden('prodid[' . $orderid . ']', $prodid);
// ...generates <input type="hidden" name="prodid[1]" value="57" />
// this time we index the prodid array with the $orderid value.
echo form_hidden('name[' . $orderid . ']', $name);
// ...generates <input type="hidden" name="name[1]" value="product_num_1" />
// we did the same thing here, made the name[] an array and used $orderid as the index.
}
In your model or controller, you can retrieve the data and turn it back to an array, like so:
Code:
function my_data_accepting_function()
{
$orderids = $this->input->post('orderid'); // array of order id values
$prodids = $this->input->post('prodid'); // array of product ids indexed with order id values
$names = $this->input->post('name'); // array of names indexed with order id values
$openorders = array(); // array we will use to re-create the POSTed open orders
// loop through the $orderids array
// this will give us the order ID values that we can use to retreive the prod and name values associated with that order.
foreach($orderids as $orderid)
{
$prodid = $prodids[$orderid];
$name = $names[$orderid];
$openorders[] = array('orderid' => $orderid, 'prodid' => $prodid, 'name' => $name);
}
}
