[SOLVED] A form calling itself

[TapeGun007]

Ok, I have a sneaky suspicion that I'm not searching for the right answer here, because it's got to be simple and I can't find it.

 

Let's say I have a form called form.php:

 

<form method="post" action="form.php">

<input name="stuff" type="text"></input>

...

</form>

 

So, basically the form will call itself with form information from "stuff".

 

Now, the PHP code I want before the form is:

<?php

if ($_POST["stuff"]=="") {

  echo "No Stuff!";

}

?>

 

Of course, the IF statement gives me this error:

PHP Parse error: parse error in C:\inetpub\wwwroot\_Meir\form.php on line 5

 

I did my homework:

I know WHY I get the error, it's because when the form first loads, that variable "stuff" doesn't contain anything.

 

What I can't find is the answer.  And I know it's some rather simple. *sigh*

if(isset($_POST['stuff']) && $_POST['stuff']=="")

Ah... isset is what I needed to know.  Thanks, I fixed it and it works!

 

Thanks.  I knew it was something really stupid.

 

All I needed was the if(isset($_POST['stuff'])
