or you can use check for the name of the submit button using a specific
SUPERGLOBAL array.
e.g.
if ( ! empty($_POST[submit]) ) {
/* form was submitted */
} else {
/* form hasn't been submitted, show it */
echo 'form name=something method=post'
.' form fields/button goes here '
.'input type=submit name=submit value=send form'
.'/form';
}
Best to check if a variable exists
Using the other method will throw an error: Notice: Undefined index: action
in c:\program files\apache group\apache\htdocs\testerr.php on line x...

Subject: Re: [PHP-DB] how do I use same page for submit and results?
But now I'm not using anything that I can check except for the
button click. Any ideas how to do this?
assign a name to the button and check for that.
input type=submit name=action value=Show List
...
if ($_REQUEST[action] == Show List) {
/* form was submitted */
...
} else {
/* form hasn't been submitted, show it */
...
}
