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...

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 */
   ...
}
