is_category / in_category -> echo value from array

  • Hi,

    I’m trying to echo a value from an array with several names of categories.
    The problem is that I can’t figure out how to echo the specific value (=the category) rather than the word “Array”.
    Could you help me? Thanks!

    function cat_background_image (){

$category_class = array('wissen', 'meinung', 'wirtschaft'); //category_names

if ( is_single() ) {

if(in_category($category_class))  echo  'class="bg_' .$category_class. '" ';

} else {

if(is_category($category_class))  echo  'class="bg_' .$category_class. '" ';

}
}

  • I think this is what you want (UNTESTED). Replace this:

    if(in_category($category_class))  echo  'class="bg_' .$category_class. '" ';

    with this:

    foreach ($category_class as $cat_class ) {
   if (in_category($cat_class)) {
      echo  'class="bg_' .$cat_class. '" ';
      break;
   }
}

    Use a similar replacement for the is_category() test.
