passing variables from a URL or script

gmdavis

I am working on a framework for my site that will create all pages from a series of includes. For unimportant reasons, I want to be able to also pass variable names through the URL to replace specified includes with a different file.

Each file will begin with a series of definitions like so:

if (!isset($c1)) {$c1="blah1.txt";} //First item in the center column

An example of the URL would be:

http://www.example.com?c1=blah2.txt

Later in the body of the document I might have:

<?php @include "$c1"; ?>

The 'if statement' should let the URL to define the variable and only use the value in the script if it is not passed in the URL. Later in the script when the variable is included, it should use the one supplied by the URL and the one in the script should be forgotten.

Sometimes this actually works as expected and "blah2.txt" replaces "blah1.txt". Usually, however, BOTH "blah2.txt and "blah1.txt" show up on the page until I refresh.

What is happening?

[/b]Dunno that you need isset, if (!$c1) should work...

[/b]Concur, quid pro quo, I haven't run your script.

Hmm, not enough data I think. It could be anything from ye olde reg_globals issue to the character of the variable names in the URL. Wanna post more code...also, maybe a real variable name if 'c1' isn't the type of vars you're using? And, yes, if they're BOTH showing up, seems strange indeed..like I say, more code, mebbe.....
