Lost variable

[alfpalafox]

Hello all,

This is my problem I hope you cuold help me:

I'm receiving a ID_NUMBER that identifies each student, then I post that ID_NUMBER to make a query and retrieve the general data for that single student in another script.

After that, I allow users to make changes to the data shown. And when they clic on the "Make changes" button another script runs to make all the changes in the database. But nothing happens, I think the ID_NUMBER I receive in the first script is lost smoewhere.

What can I do to pass again the variable through the second to the 3rd script.

Thanks.

The usual way is to pass the variable in a "hidden" input field:

<input type="hidden" name="ID_NUMBER" value="<?php echo $ID_NUMBER; ?>">

Then it will be available as normal on the "action" page.

$ID_NUMBER=$_REQUEST['ID_NUMBER'];

or if you have PHP automatically creating request variables, just refer to $ID_NUMBER.
