Hi,
Obviously, the issue is around the comments var. It works, but it
doesn't and I'm hoping someone can explain why.
Both echo strlen($comments); and echo $comments; throw a Notice
about an undefined variable. But the variable "comments" HAS to have
been defined in order for the two echo statements to work!
The variable 'comments' is also in SESSION data, which will also get
the same Notice of an undefined variable.
What the heck am I missing? Why do I get the undefined var in those two
statements?
===================
<code>
echo strlen($_POST["comments"])."<br />"; //WORKS
$commments = $_POST["comments"]; // WORKS but not needed; done elsewhere
too.
// echo strlen($comments); // GETS Notice: Undefined variable: comments
in C:\xampp\htdocs... and nothing displays.
echo $_POST["comments"]; // WORKS
//echo $comments; // GETS Notice: Undefined variable: comments in C
.... and nothing displays.
</code>
===================
I'm obviously missing something here since it appears the var is set
according to the 2 statements that do display what I expected. Can you
straighten me out? I've had this happen before with other vars and it's
always confusing.
TIA,
Twayne`
