Using in_category() with category name, not ID

    Hi,

    How do I test whether a post in the loop is in a particular named category? I know I can use, say, in_category(6) if I know the category ID, but what if I only know the category name? I’d like to use in_category("catname").

    One solution might be to get the category ID from the category name. Is there a simple way to do that?

    <?php
foreach((get_the_category()) as $cat) {
  if($cat->cat_name == 'NAME')
  {
    #bleh ...
  };
}
?>

    Maybe it’s not == but =

    Thanks, that works perfectly.

    I’ve been searching for this!

    Is there any way to simply feed a variable into in_category()? I was thinking something like this.

    <?php $asidecatid = $wpdb->get_var("SELECT term_ID FROM $wpdb->terms WHERE name='Asides'"); ?>

    then later in the loop…

    <?php if ( !(in_category($asidecat)) ) { ?>

    This does not work, though I am not sure if it is because of my poor php or limitations of the function. Any suggestions?

    The issue I have with the example above is if I want to display data if the current loop post is not in asides. I believe the code above will execute multiple times if the post has multiple non-asides categories.

    Just change:

    <?php if ( !(in_category($asidecat)) ) { ?>

    To:

    <?php if ( !(in_category($asidecatid)) ) { ?>

    So that it matches the variable you set.
