RE: [PHP] How do I stop foreach if $menu not set??

Change introduction to a variable with $ in front of it or put it in quotes introduction. What Can I do to stop the foreach function from working if $menu is not set?? ? if ($menu==(introduction)) {$sub = array( 'overview.php' = 'Overview', 'moreinfo.php' = 'More Info' ); }

You should be able to contain your foreach statement within an if statement: if (isset($menu)) { foreach ($sub as $link = $name) ( $sublink .= lia href='.$link.'.$name./a/libr; } else { print menu variable not set } Hope this helps. Hugh - Original Message -
