Question

I can't seem to find an answer to this question anywhere, so I'm wondering if anyone might be able to help?

How do I combine the is_page and in_category clause?

At the moment, home-2 (the slug) doesn't seem to want to work.

<?php if(is_page( 'Home' )) { ?>

    <?php } elseif (is_page('home-2')) { ?>

<?php } elseif (in_category('projects')) { ?>

<?php } else { ?>

<?php } ?>

Thanks.

Answer 1

In Condition '&&' is 'AND' and '||' is 'OR'. Use this and combine many clause.

if(is_page('home-2') && in_category('projects')){
                  OR
if(is_page('home-2') || in_category('projects')){
    //Your Statement here
}

Answer 2

If you want to combine conditions in an if -clause you can either join them with && (evaluates as and ) or || (evaluates as or ).

if (cond1 && cond2) // Will only be true if both cond1 and cond2 is true.
if (cond1 || cond2) // Will be true if either of cond1 or  cond2 is true. 

This code should be sufficient for your solution:

<?php if(is_page('Home')) { ?>
    <!-- You're on page Home -->
<?php } elseif (is_page('home-2') && in_category('projects')) { ?>
    <!-- You're on page home-2 in category projects -->
<?php } else { ?>
    <!-- You're somewhere else -->
<?php } ?>
