   I've developed an alternate post.php template that I use for posts in a certain category. But what I'd like to do now is modify the conditional a little, and PHPwise I'm a little lost.

   This is how my code is now:

   <?php if ( in_category('26') ) { ?>
           <div class="post-ws">
           <?php require('post-ws.php'); ?>
   <?php } else { ?>
           <div class="post">
           <?php require('post.php'); ?>
   <?php } ?>

   How would I change the IF to use the alternate post-ws.php if a post is in category 26 and not in any other category aside from category 3?

   i.e.:
   Post is in..................................Template to use
   Cat-26 only..............................post-ws.php
   Cat-26 & Cat-3........................post-ws.php
   Cat-26 & Cat-Other................post.php
   Cat-26, Cat-3 & Cat-Other.....post.php

   I just saw a similar question about Pages:

   I am not a coder by any means but I think the logic should be similar.

   this covers the php part of your question fairly well.

   http://mgeisler.net/php-tutorial/control-structures/

   specifically the bits that go on about this sort of stuff:

   To compare the value of a variable up against other variables or numbers, you have a number of different comparison-operators:

   * ==: Is equal to,
   * !=: Is not equal to,
   * <: Is strictly less than,
   * <=: Is less than or equal to,
   * >: Is strictly greater than,
   * >=: Is greater than or equal to,
   * && (and): Both left and right arguments must be true,
   * ||, or: Left or right argument must be true (or both),
   * ^, xor: Exactly one of the left and right arguments must be true.
   * !: Negation, changes true to false and false to true.

   Using these operators you can construct every Boolean expression you’ll ever need. Take for example the following if-statement:

   if (($x == 0 && $y != 0) || ($x != 0 && $y == 0))
     // Exactly one of $x and $y is zero.
   }

   rudolf45,

   Thanks for the link. But what that doesn't answer is the part I'm having the most trouble with. How do I phrase an if condition to result in true if a post falls into a category other than 26 & 3?

   grrrr.

   if ($cat != 26 && $cat != 3)

   please read.

   whooami,

   I could have sworn I tried that.

   Thank you for your time. I'll get back to this in the morning with fresh eyes.

   if (!is_category('26') && !is_category('3') )

   Didnt I just explain the logic?

   Yes you did explain it. And I said thank you.

   However, neither

   if ($cat != 26 && $cat != 3)
   or
   if (!is_category('26') && !is_category('3') )
   worked.

   When presented with a category that is part of categories 26, 3 & 1, each of these statements evaluated as true. Likewise, they evaluated as true for a post in categories 26 & 3.

   Nevermind...I'm going to try a different solution.

   if ($cat != 26 && $cat != 3)

   thats not going to work because I made up the variable $cat for the sake of the explanation :)

   Its easier to type.

   is_category checks to see if a particular category page is being displayed.

   in_category checks to see if a given post is in a category.

   you need this:

   if (!in_category('26') && !in_category('3') )

    That one doesn't work either I tried that before I even posted this topic.

    Thank you for your help. I'm going to try to solve the problem a different way.
