How would I structure the loop to go through inputs?
- by dmanexe
I am attempting to make a loop that will go through an array structured like this:
$input[n][checked]
$input[n][input]
The 2nd input acts as a price multiplier, but doesn't have to exist (field can be blank). I don't think a foreach loop is right because I don't think it handles the inputs from the form in the correct dimensional array order to keep the information together.
I have inputs on a form that look like this:
<input type="checkbox" name="measure[<?php echo $item->id; ?>][checked]" value="<?php echo $item->id; ?>">
<input class="item_mult" type="text" name="measure[<?php echo $item->id; ?>][input]" />
I am attempting to make the loop go through and act as a multiplier on the input relative to its sibling field. (i.e. input[1][input] would be an integer that I want to retrieve later, grouped with input[1][checked])
<? $field = $this->input->post('measure',true);
$totals = array();
foreach($field as $value):
if ($value['input'] == TRUE) {
$query = $this->db->get_where('items', array('id' => $value['input']))->row();
$totals[] = $query->price;
?>
<p><?=$query->name?> - <?=money_format('%(#10n', $query->price)?></p>
<?php
}
else { }
endforeach; ?>
And finally, the last code to array_sum and print the grand total:
<? $grand_total = array_sum($totals); ?>
<p><?=money_format('%(#10n', $grand_total)?></p>
Eventually, I will need to store these records in a database, so I am sending complete item IDs through, etc.
