Multiple isset?

[grantus]

I have a page setup like this:

It shows Area > Year > Month & Day > Pictures

By default, it shows the area. I then link it like this:

<a href=\"{$_SERVER['PHP_SELF']}?area=$whatarea\">{$row['area']}</a> 

If they click on the area link, it gets all the years:

if (isset($_GET['area'])) 

And then I link it like this:

<a href=\"{$_SERVER['PHP_SELF']}?area=$thearea&year=$year\">{$year}</a> 

Then this is where I have a problem. I want to continue with "elseif" but is it possible to have more than one isset?

If I do this:

elseif (isset($_GET['year'])) 

It obviously doesn't work, because in the previous link there's "area" and "year".

I could just do "if" for each one, but then all the results would show as the user continues through the page.

So my question is: how do I setup the elseif to accept "area" and "year"?

Thanks.

Just tie them together in one elseif?

elseif (isset($_GET['area']) && isset($_GET['year']))

Nah that doesn't work, that was the first thing I tried, that's why I'm stumped on this. I've even tried:

elseif (isset($_GET[$area][$year]))

See what happen if you put both isset() statements within brackets:

elseif((isset($_GET['area'])) && (isset($_GET['year']))) 

That should work. If not, show us some more code so we can see what's going on in more detail.

When you only want 'area', you should also make sure 'year' is NOT set.

if(isset($_GET['area']) && !isset($_GET['year'])) 
  //only area supplied in url
else if(isset($_GET['area']) && isset($_GET['year']))
 //both area and year supplied

It works! Damn I didn't even think of that, even though I've done that in the past, LOL. Thanks for the help.
