I have not found a satisfactory way of doing this yet!!!!


$text = $_REQUEST['text_size'];
if ($text) {
echo $text;
}


I send the $text_size variable to the browser with lines like...

<a href="<? $_SERVER['PHP_SELF'];  ?> ?text_size=small" class="size1" 
id="one"> A</a>


When the page initially loads I get a undefined index error as it does not 
exist but is there a way of wrapping in in a switch statement or funtion so 
the variable is only used when $_REQUEST['text_size']; actually exists.
