How Do I Get The Category ID???

  • Hey Folks,

    I am in the process of writing some custom headers that will be used to refer users to our new site. I am doing this using the code below. However, I need a way to get the current category ID that is shown. I am not looking for conditional tags. Rather, I am in need of something that can pull the category ID from a global position. In other words I need something that can work in place of $get_cat as seen below:

    <?php
switch ($$get_cat)
{
case 1:
  header( 'Location: https://www.newsite.com/category1' ) ;
  break;
case 2:
  header( 'Location: https://www.newsite.com/category2' ) ;
  break;
default:
  header( 'Location: https://www.newsite.com' ) ;
}
?>

    I’m confused. Where, exactly, are you trying to get the category ID from? What category ID are you trying to get?

    Thats just it Otto, I don’t know where to get the category ID from. Thats what I am asking. I am trying to get any category ID that is being shown.

    The code above will be placed in the header of the site. Thus when a category page is shown the user will be redirected to the same category page on the new site.

    So… you’re trying to get the current category ID only when a category archive is being shown? If so, then this would do it:

    if (is_category()) {
	global $wp_query;
	$cat_obj = $wp_query->get_queried_object();
	$cat_id = $cat_obj->term_id;
}

    So, just for clarification: Using the code above, $cat_id, can then be used in my switch statement as followed?

    <?php
if (is_category()) {
	global $wp_query;
	$cat_obj = $wp_query->get_queried_object();
	$cat_id = $cat_obj->term_id;
}
switch ($cat_id)
{
case 1:
  header( 'Location: https://www.newsite.com/category1' ) ;
  break;
case 2:
  header( 'Location: https://www.newsite.com/category2' ) ;
  break;
default:
  header( 'Location: https://www.newsite.com' ) ;
}
?>

    Should work, yes. Although you may want to add $cat_id = 0; at the top of that code, to ensure that cat_id is set to something.
