Problem identified by Robert Burne and Tolulope Aina: How can the value of a variable be sent from one PHP script to another, transparently from the point of view of the interface with the user (web page)? This problem occurs when a user inputs some values, say S1, in a form whose action is, say, "test6.php3", and these values need to be sent further to the action associated with this script (the script includes a form), say "test7.php3". A practical problem, identified by Tolulope, is the case when a use has more than one database. In the first page, the uses inputs the name of the database. In the second page the user chooses some tables to be displayed from the chosen database. In the next page, these tables are displayed. The mechanism, was identified by Robert. It is based on the PHP construct: *************************************************************** " ?> *************************************************************** This mechanism is briefly described below: FILE test5.php3 --------------- Test

Test variables - #1

This page (test5.php3) will (transparently) send a variable to a PHP script (test7.php3), without displaying it in the intermediate script/page (test6.php3).


Input a value:

FILE test6.php3 --------------- Test

Test variables - #2

This page (test6.php3) will send the variable to a PHP script (test7.php3), without displaying it.


" ?>

FILE test7.php3 --------------- Test

Test variables - #3

This page (test7.php3) displays the variable.


The value is: "; echo "$variable2"; ?>
