Stage

[25lez25]

When you are working with "stage" like

<?php
if ($stage == "0" ) and lets say it goes up to ($stages=="3")

and you have

<form name="stage1" action="usetheinfo.php?stage=1" method="post">

what is the typical code like for usetheinfo.php to process the "stage" info?

Just trying to get a little understanding of how to process "stage".

Thanks

// Copy the value to make it work with servers that do
// not have register_globals on
$stage = $_GET[ "stage" ];

// Decide which stage it is
if( $stage == 1 )
{
   // Do something
}
else if( $stage == 2 )
{
   // Do something
}
else if( $stage == 3 )
{
   // Do something
}
else
{
   echo "Invalid Stage";
}

$stage is just a variable. What are you trying to do? That message is pretty vague.

Create a drop down box from first field,user selects a choice, which determines values in next drop down box etc;

There are 2 ways you could do this.

The first method is to use javascript. You can use onchange events to change the values in the different selects. There are scripts availabe to do this.

The second method would be to process each select on a different page. The trick to getting this system to work is that you have to reset all of your input from the previous form, into hidden fields on your new form, so it will be passed to the next page.

eg:
page A -> page B -> page C
page C will only get page A's information if you set page A's information as part of the form on page B.
