Question

I have a php page to capture sales orders. it has a dependant drop down list that pulls mysql table information based on the selected value.

When the user enters an order qty, I want a few things to happen:

• Firstly, the entered value should be written to a variable $line1qty. I have the entry:
  <? $line1qty=$_POST[line1qty]; ?> in my code however this is not working as I am not sure it is set when the javascript refreshes the page.

• Secondly, the next table row should become visible, there will be a maximum of 72 table entries, I want all the rows without a selected value hidden by default.

Any assitance would be appreciated, I know i am just missing something simple but am still very new to PHP. Thanks again.

My code for the page is:

<style type="text/css">
<!--
@import url("style.css");
-->
</style>

<script language="JavaScript">

function autoSubmit()
{
    var formObject = document.forms['theForm'];
    formObject.submit();
}

</script>

<?php

$packcode = $category = $sellingunit = null; //declare vars

if(isset($_GET["packcode"]) && is_numeric($_GET["packcode"]))
{
    $packcode = $_GET["packcode"];
}

if(isset($_GET["category"]) && is_numeric($_GET["category"]))
{
    $category = $_GET["category"];
}

if(isset($_GET["sellingunit"]) && is_numeric($_GET["sellingunit"]))
{
    $sellingunit = $_GET["sellingunit"];
}

?>

<form name="theForm" method="get">

<? $line1qty=$_POST[line1qty]; ?>


Capture the sales data 
<table id="hor-minimalist-a">

        <?

Thanks again, Appreciate the assistance this forum provides.

In these lines :

<form name="theForm" method="get">
<? $line1qty=$_POST[line1qty]; ?>

You use “$_POST” but your form method is $_GET, so use $_GET["line1qty"].
