No Clue--Dynamic Active Nav Indication

lisaNewbie

Hi,

I am more than new, if that is possible. I understand it, but don't know how to look for what I need.
This is working

<li<?php if ($thisPage=="events" || "events-expo" || "expo-industry" || "expo-lesson" || "expo-tips") echo " id=\"active\""; ?>>
		<a id="nav_events" href="events.php">EVENTS</a></li>
<li<?php if ($thisPage=="faq-teachers" || "faq-sprostart" || "faq-prostart-invite" || "faq-students") echo " id=\"active\""; ?>>
		<a id="nav_faq" href="faq-teachers.php">FAQs</a></li>

The problem is that it doesn't come off when you go to a different menu choice. I need it to remove the id from the current item when you click on a different menu item. I realize that it has something to do with the fact that each IF statement has OR options so it is not exclusive and will be applied to all the OR options, but I don't know how to amend that.

I will need advice in an a-b-c kind of manner, too. Sure do appreciate it.

Thanks!! :o

One problem I see is that this:

if ($thisPage=="events" || "events-expo" || "expo-industry" || "expo-lesson" || "expo-tips")

is the same as this:

if ($thisPage == "events")

The logical OR operation combines entire logical statements, and $thisPage == "events" is a single logical statement, thus you're just OR'ing the boolean value of a bunch of strings together with one logical comparison.

Instead, either repeat the comparison for each statement or write it more compactly using something like [man]in_array/man, e.g.:

if(in_array($value, array("option1", "option2", "option3", "etc.")))

That was exactly what I was looking for. I did look up arrays but I only found them inside an if-else statement. That didn't seem to apply to what I was trying to do.

Thanks again! I sure do appreciate it!!
