Looping Around Form Array Values

Hi,

I'm looking for a little guidance on the best way to loop around some form input fields.

I have a form with a few input boxes. I have used the [] on the end of the names in an attempt to get these into an array.

View

Code:

<input type="text" class="form-control" id="url[]" name="url[]" placeholder="" value="<?=set_value('url[]'); ?>" />
<input type="text" class="form-control" id="price[]" name="price[]" placeholder="199" value="<?=set_value('price[]'); ?>" />

I'm now trying to get each of the values out and save them to the database.

I assume I need a foreach loop to do this, but am not sure on the best way to do this. I have the following in my controller so far.

Controller

PHP Code:

$post_array = array(
   'url' => $this->input->post('url[]'),
   'price' => $this->input->post('price[]'),
   'order_id' => '1'
);
$this->order_model->add($post_array); 


Any help/guidance would be much appriciated!

Thanks,

MoFish

PHP Code:

$urls = $this->input->post('url');
$prices = $this->input->post('price');
foreach ($urls as $key => $url)
{
    $post_array = array(
       'url' => $url,
       'price' => $prices[$key],
       'order_id' => '1'
    );
    $this->order_model->add($post_array);
} 


Thank you! worked perfect.
