<?php if( is_category('3, 14, 55, 11') ) echo 'Hello';
elseif( is_category('1, 10, 22') ) echo 'Goodbye';?>

thank'you very much esmi !! :)))
..may I ask another thing ?
I must write this:
<?php if( is_category('4') ) echo '';?>
but the category must be this:
category-<?php echo get_post_meta($post->ID, "whatiwant", true); ?>
and the echo must be this:
<?php echo get_post_meta($post->ID, "whatiwant", true); ?>/">
how can I write this in php..??
sorry again..!

ops.. I have write wrong href..
and the echo must be this:
<li><a href=" <?php echo get_option("home"); ?>/<?php echo get_post_meta($post->ID, "whatiwant", true); ?>/">example</a></li>
Sorry? What is it that you're actually trying to do?

well, I have a custom field with a specific value (es. xxxxx)
this specific value is a part of a category name (es. category-xxxxx)
I wish that:
if category-xxxxx exists, display a link of this kind
<a href="www.site.com/category-xxxxx/>category of xxxxx</a>
else do nothing
thanks a lot esmi
The code I gave above isn't going to work then. It tests to see if you're in a particular category - not whether that category exists.
See if this works:
<?php
$cat_name = 'category-' . get_post_meta($post->ID, "whatiwant", true);
if( get_cat_ID( $cat_name ) ) :?>
<li><a href="<?php bloginfo('url'); echo $cat_name; ?>/">example</a></li>
<?php endif;?>

I have resolve half problem with:
<?php if( is_category('categoria-' . get_post_meta($post->ID, "whatiwant", true)) ) echo '';
but the problem, now, is echo ..
I cannot display the correct url made of a static url + a query string.
es.
<li><a href="http://www.mydomain.com/categoria-<?php echo get_post_meta($post->ID, "whatiwant", true); ?>/">example</a></li>
how is the correct sintax?
Thank'you very much, I really appreciate your efforts to help me!

Not sure if I completely understood your need, but if you want to place the code on the category.php and test: “if it is a certain category show this link, else shows nothing” then this code may work for you.
<?php if (is_category('id or name here')) { ?>
Category of <?php the_category(' '); ?>
<?php } else { ?>
<?php } ?>No need to add link tag to the <?php the_category(' '); ?> as it will generate by itself.
Or maybe for the custom field:
<?php if (is_category(id or name here)) { ?>
<?php if( get_post_meta($post->ID, "whatiwant", true) ): ?>
<?php echo get_post_meta($post->ID, "whatiwant", $single = true); ?>
<?php endif; ?>
<?php } else { ?>
<?php } ?>

uhm.. sorry but the problem is more difficult.
I have tryed this line:
<?php if( is_category('photographs-' . get_post_meta($post->ID, "artist", true)) ) echo '<li><a href="' . get_option('home') . '/">photographs</a></li>';
..and it works fine!
but the echo link must be different that home url
I would display this:
http://www.domain.com/artist/photographs-of-/
how I code php?

I have resolved!
if( is_category('photographs-' . get_post_meta($post->ID, "artist", true)) ) echo('<li><a href="http://www.domain.com/artists/photographs-'.get_post_meta($post->ID,'artists',true).'">'.'
photographs'.'</a></li>');but It works only on archives page.. but not in a simple page..
anyone knows why?

For regular pages, try if in_category.
if( in_category('photographs-' . get_post_meta($post->ID, "artist", true)) ) echo('<li><a href="http://www.domain.com/artists/photographs-'.get_post_meta($post->ID,'artists',true).'">'.'
photographs'.'</a></li>');

You probably just need to include it to the page.php - you were only referring to archive.php...
