    Hi all,

    I am using the following script to show all my categories with images as background (taken from here):

    <?php
$category_ids = get_all_category_ids();
foreach($category_ids as $cat_id) {
  $cat = get_category($cat_id);
  $link = get_category_link( $cat_id ); ?>
  <div class="cat-image">
  <a href="<?php echo $link; ?>" title="link to <?php echo $cat->name; ?>">
  <img src="<?php bloginfo('template_url'); ?>/images/<?php echo $cat->slug; ?>.jpg" />
  </a>
  </div>
  <?php
}
?>

    The problem is that this script shows all categories with no exceptions and there are some specific categories that I want to exclude from this list. how do I exclude specific categories from the list using this script?

    Thanks,
    Eyal.

    Solved it!

    just need to change $category_ids = get_all_category_ids(); to $category_ids = get_categories(); and add relevant arguments

    [edit: well done 😉 ]

    consider to rewrite the code based on get_categories()

    http://codex.wordpress.org/Function_Reference/get_categories

    example:

    <?php
$args = array( 'exclude' => '3,7,25' );
$category_ids = get_categories( $args );
foreach($category_ids as $cat) {
  $link = get_category_link( $cat->term_id ); ?>
  <div class="cat-image">
  <a href="<?php echo $link; ?>" title="link to <?php echo $cat->name; ?>">
  <img src="<?php bloginfo('template_url'); ?>/images/<?php echo $cat->slug; ?>.jpg" />
  </a>
  </div>
  <?php
}
?>

    (untested)

    alternatively, use the list of to-be-excluded cat ids in your code to skip the output;

    example:

    <?php
$exclude_ids = array( 3, 7, 25 ); //list of the category ids to be excluded//
$category_ids = get_all_category_ids();
foreach($category_ids as $cat_id) {
  if( in_array($cat_id, $exclude_ids) ) continue;
  $cat = get_category($cat_id);
  $link = get_category_link( $cat_id ); ?>
  <div class="cat-image">
  <a href="<?php echo $link; ?>" title="link to <?php echo $cat->name; ?>">
  <img src="<?php bloginfo('template_url'); ?>/images/<?php echo $cat->slug; ?>.jpg" />
  </a>
  </div>
  <?php
}
?>
