zerbon Posted November 8, 2009 Share Posted November 8, 2009 I made this simple example below that I thought should work; I'm not sure what I am missing? Unless I am mistaken, when you click on one of the list items the paragraph should update to "You clicked [whatever you clicked]"? I'm sure it is a simple mistake somewhere, but I cannot seem to see it?!

Alex Posted November 8, 2009 Share Posted November 8, 2009 Your code would only work if register_globals is on, which is never a good idea. Instead you should be using the $_GET superglobal. So it would be $_GET['fruit']. Additionally you should be using isset() to confirm that the fruit index is defined within the $_GET superglobal otherwise (depending on your error reporting level) a warning will be thrown. Something like this would work: if(isset($_GET['fruit'])) { echo '<p>You clicked ' . $_GET['fruit'] . '</p>'; } Link to comment https://forums.phpfreaks.com/topic/180801-solved-seemingly-simple-code-not-working/#findComment-953849 Share on other sites More sharing options...
