Keeping Dynamic Table Rows shown after form post errors - php

Question

I have a dynamic HTML table that allows users to enter receipt items in, and they can add as many rows as necessary.
If they forget to fill out a field upon form POST, I want all those rows with the data to stay shown, instead what happens, is they dynamic rows disappear and no values are saved in the one row that shows on default.
How can I achieve having those dynamic table rows shown with the values they've entered to avoid them having to enter all the data again?
<?php

$expenseType = safeDataMySQL($_POST['expenseType']);
//Save page, redirect to same page but increment receipt number.

$getRef = mysql_query("SELECT CAST(SUBSTRING(refNumber,4) AS UNSIGNED INTEGER) AS referenceNumber FROM expense_main ORDER BY referenceNumber DESC LIMIT 1") or die("Ref No: " . mysql_error());
if(mysql_num_rows($getRef) > 0)

Just to get you started. You can add the rows from $_POST["rows"]
foreach ($_POST["rows"] as $rowstring) {
list($date, $cat, $desc, $amt) = explode(",", $rowstring)
?>
<td><?php echo $date; ?></td>
<td><?php echo $cat; ?></td>
<td><?php echo $desc; ?></td>
<td><?php echo $amt; ?></td>
<td> </td>
<?php
}
Assuming you add a hidden input with a comma delimited string each time a dynamic row is added.
FWIW, I would also recommend doing all of the database queries (ie $getCats = ...) prior to rendering anything to the screen so that in case the 'or die()' happens, you wont get a half rendered page.
