At the moment I have this, but I want to change it to one switch button <a href="<?php echo $_SERVER['PHP_SELF'];?>?session_switch=1">switch it</a>. I have tried but keep getting wrapped up in nested if-else statements. Does anyone know how to make an efficient one button on-off switch. <? $session_switch = isset($_GET['session_switch']) ? $_GET['session_switch'] : 0; if ($session_switch==1) { echo "on"; ?> //do something here <? } else { //do something else } ?> <a href="<?php echo $_SERVER['PHP_SELF'];?>?session_switch=0">off</a> <a href="<?php echo $_SERVER['PHP_SELF'];?>?session_switch=1">on</a> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
