Question

I have a PHP script that generates table rows with hidden input tags that have names like title1, title2 etc and price1, price2 etc. The user has the ability to remove and add rows as they see fit. My question is when I submit the rows how can I read those hidden inputs in order, either through PHP or Javascript?

EDIT: Sorry about the lack of detail. Here’s some code:

The PHP that generates the rows

$result = mysql_query("SELECT * FROM `table`");
$i=0;
while ($list = mysql_fetch_array($result))
{
$i++;
$title = $list['title'];
$price = $list['price'];
$plu = $list['plu'];

?>

<tr id="row<?php echo $i; ?>"><td><input type="hidden" name="title<?php echo $i; ?>"     value="<?php echo $title; ?>"></td></tr>
<tr><td><input type="hidden" name="price<?php echo $i; ?>" value="<?php echo $price; ?>"></td></tr>
<tr><td><input type="hidden" name="plu<?php echo $i; ?>" value="<?php echo $plu; ?>">        </td></tr>

<?php
}
?>

Now if users can remove rows, I know I can tell exactly how many rows there are, but when it comes time to read them and save them in order I’m lost.

I’m not sure you’re guaranteed to get them in order based on location on the page, but since you can name the elements yourself, you could name them title[1], title[2], …

For example:

<input type="hidden" name="title[1]" value="foo">
...
<input type="hidden" name="title[2]" value="bar">

This will allow you to access the submitted elements in PHP by, for example:

$_POST['title'][1], $_POST['title'][2], etc.
