I have changed it a bit, and don't have the old code now!!!
I saw a post which identified a problem using isset when $var = ""; as
it returns true, so I changed my code to use...
if ($_GET['id'] != "")
{ $article="$id.php";
if (file_exists($article)) { include $article; }
else { echo "The article you've requested does not exist!"; }
}
else {
echo "No article selected";
}
This works fine, except that when the url is www.mysite.com/index.php
I get the following error...
Notice: Undefined index: id in
/home/5217/tomchubb/public_html/index.php on line 14
No article selected
I kmow this will disappear when I turn off error reporting, but how
can I suppress it properly?

I am trying to create my own news system and to start with I'm using
static news pages until I get the db working properly.
I'm using the following code:
<?php
if(!isset($_GET['id']))
{ $article="$id.php"
if (file_exists($article)) { include $article; }
else { echo "The article you've requested does not exist!"; }
}
else { echo "You did not select an article"; }
?>
I am testing using the following links...
www.myurl.co.uk/index.php
www.myurl.co.uk/index.php?id=1
www.myurl.co.uk/index.php?id=2
When I try the first one, I'd expect it to say you did not select an
article, but it says
Notice: Undefined variable: id in
/home/5217/tomchubb/public_html/index.php on line 15
The article you've requested does not exist
When I try the third link, I would expect it to say The article
you've requested does not exist! but it says:
Parse error: parse error in /home/5217/tomchubb/public_html/index.php on line 16
Lines 15 & 16 are:
if (file_exists($article)) { include $article; }
else { echo "The article you've requested does not exist!"; }
I don't understand why this isn't working and I've tried looking into
this for 2 hours!
Can anyone tell me where I'm going wrong please?
Thanks,
Tom
What I notice is that the first error says it's on line 15, then you
give lines 15 and 16 in the second example but line 15 doesn't have "id"
in it. Are you sure your looking at the right lines? Try posting the
whole script and maybe someone can catch the problem.
I always use
if(!empty(...)) {
it takes care of empty variables and variables that haven't been set at
the same time. :)
