[Resolved] if/else logic

zzz

It's been a long day and I can't seem to put this simple logic together...

I have a navigation with four buttons. Each button has ON and OFF state.

I have four pages. Each page has a marker, say

$mypage = "page1", $mypage = "page2", $mypage = "page3"" and $mypage = "page4" accordingly.

I've abstructed the menu into a separate include file. Now all I need is to put the proper logic in place so that when I'm on page1 I need button1_on.gif on page2 - button2_on.gif etc.

I've tried the following:

Now, I'm getting crossed at some point when I try to weave in all four buttons. So, did anyone manage to take a nap today and can think clearly, unlike me?

<img src="button1_

<? 
switch($mypage)
   case page1:
           echo "on";
           break;
   case page2:
           echo "on";
           break;

   default:
           echo "off";
           break;
}
?>

that might help a bit.

That looks great but maybe we can tighten it up a bit? It seems like it's going to be too much code if I repeat it four times?..

clandestine555 your code may work, but it depends on how zzz wants to use the statement.

What wasnt pointed out was that you need to fix this in your if statement

<img src="button1_<? 
if ($mypage == "page1") { 
echo ("on"); } 
else { 
echo ("off"); 
} 
?>.gif">

GOT IT!

I was on the right truck! Only I was writing $mypage = "page1"

when I needed
$mypage == "page1"

Did I mention it was a long day! 🙂

Thanks everyone.

i find switch statements to be better (opinion) when i create a dynamic menu with text or images, but that's just me, either way works, but his way you use 5-20 if statements, a switch only needs to be used once, depending on how you do it.
