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?
