passing URL variables

burkeja

I have not successfully tested the Tutorial from PHPBuilder that creates a discussion thread with PHP and MS Access.

I created the forum.php and node.php files and there seems to be a problem with how the "node" variable is passed from forum.php to node.php. It is passed with the URL:

<a href="node.php?node=0">Post New Message</a>

The file node.php errors on line 15:

"Notice: Undefined variable: node in :\Inetpub\wwwroot\node.php on line 15"

Line 15 in node.php is: if ( $node != 0 )

Does the variable node have to be defined in node.php if it passed to it as part of the URL?

This is my first experience with PHP and any suggestions are welcome (my experience is predominantly ColdFusion and ASP).

Thanks.

I use to be a ASP developer myself, untill I found PHP - much more challenging and rewarding to use... I will never go back to ASP.

It depends of what server you are running. Ive had this with a similiar problem before and actually still have it....but am working on it.

define(ROWS, 20)

When I define the above under apache web server its fine, but when I run it under IIS it doesnt like it at all.

I think the problem is under the php.ini

Hope that helps a bit at least

There is a setting in the PHP.INI file for register_variables. If this is set ON then there is no need to define $node.

However, there are security issues involved and these days register_variables is usually set OFF by default.

To define $node use

$node = $_GET["node"]

or $node = $HTTP_GET_VARS["node"] with older versions of PHP.

Barand is right. dont ever define $node as just "$node" if you are passing variables through a url. Because for 1, it has security issues and for 2... you may already have something named $node in your file... and for 3... its just plain sloppy. So always define $node with: $node = $_GET["node"].

My php.ini was set to sensitive. All I needed to do was check

"error_reporting = E_ALL; display all errors, warnings and notices"

and uncheck

error_reporting = E_ALL & ~E_NOTICE

and it solved my problems
