   What's the </img> at the end for?

   is_category tests to see if the current page is a category page. As soon as you select a post, the current page is no longer a category page, so - no image.

   Hey man,
   Check out the in_category(); template tag, thats what your looking for... its an if statement that says if the post is in "this" category, do this

   Codex page is here

   Hi fanalejr,
   thanks for your reply, i use it and it work, but i must add all the time the cat names every time i'add the new one as:
   

   <?php if ( in_category( array( 'fruits', 'apples', 'bananas', 'cantaloupes', 'guavas', /*etc*/ ) ) {
   	// These are all fruits
   }
   ?>

   So i'd like if the Template Tags/in_category to be dynamic and know all the category i add or the costumer add, like in :
   <?php if (is_category()) { ?>
   and the question is : how can i let the in_category to be global.
   Thanks a lot

   hi, i have the code, but it dont let other code to work:
   (!in_category('$il_asides_cat')

   i have set a banner image to be in the header of search page :
   

   <?php } elseif (is_search() ) { ?>
   <img src="<?php bloginfo('stylesheet_directory'); ?>/cat-banner/recherche.jpg"></img>
   <?php } ?>

   but in place to see the search banner (recherche.jpg), it appear the banner of first result!!!

   so please what's the solution?
   and what does mean "!" and "$il_asides_cat"?
   Thanks

   this is the code:
   

   <?php } elseif (is_single() &amp;&amp; !in_category(category_id) ) { ?>
   /content her
   <?php } ?>

   dont remove the "!" i dont know what is it's role, but the code now work in all the page and post, and other conditional tags work as a charm :p

    ! is PHP for "not" so:

    is_single() && !in_category(category_id)

    translates to:

    If this is a single post AND is NOT in the category...
