[FX.php List] FX Repost

[Steve Hannah]

Hi Gerry,

I haven't actually been using FX for a while so I don't recall the  
exact syntax for some stuff.

But the general idea is:

Suppose you have PHP scripts:
    1. RecordDetail.php  - displays record details.
    2. NewRecord.php - inserts new record.

In NewRecord.php you would have something like this:

---------

if ($form_has_been_submitted){
     save_form_to_database();
     $record_id = get_id_of_newly_inserted_record();
     header('Location: RecordDetail.php?record_id='.$record_id);
     exit;
}

display_form();

-----------

Comments on above snippet:
The $record_id is just some unique identifier for the record.   
Generally you will have a field (or group of fields) that can  
uniquely identify a record.  This is just used to pass to the  
RecordDetail.php script so that it knows which record it should display.


and in RecordDetail.php you would have something like:

$record_id = $_GET['record_id'];
display_record_with_id($record_id);

Note that all functions used in this example are fake - they are just  
pseudo-code to give the idea of what to do and when.


Hope this helps

-Steve
