I have a page with a form, and on the form are a bunch of input check boxes. In the following page, there's the following code to process the inputs from the page before (which are set as an ID).
<? $field = $this->input->post('measure',true);
$totals = array();
foreach($field as $value):
$query = $this->db->get_where('items', array('id' => $value['input']))->row();
$totals[] = $query->price;
?>
#HTML for displaying estimate output here
<?php endforeach; ?>
How would I have the loop run conditionally only if there was a check on the input on the page before?
