Is there any experience using widget logic, I want to display a widget on single custom post type with specific taxonomy. Tried using

is_tax(taxonomy_name) || is_single() && in_term(term_name).
  • I don't know what errors you are getting or what exactly your issue is, but in_term() according to my knowledge is invalid Jun 22 '15 at 11:11
  • Hi Pieter, the error I got is the sidebar widget not showing anything.

  • So, what the conditional should be for the cuatom taxonomy? As per I knew, in_category is only for default

  • Do you mean a specific term, or for all terms under a specific taxonomy Jun 22 '15 at 11:29
  • Yes :), for example I have custom taxonomy with name resources, and child taxonomy of the resources is economic_news so I want to display the widget only on the single page of that taxonomy.

Before I start, I must say that your terminology is quite confusing and plain wrong. You should take your time and read through my answer to this question: Is There a Difference Between Taxonomies and Categories?

As I stated before, there is no in_term() function to check if a post has a specific term. There is however a has_term() function which accepts the term as first parameter and the taxonomy name as second parameter. So your condition should look like this: (if this is for a specific post type outside the loop)

global $post;
if ( $post->post_type == 'my_post_type' // checks the post type of the post
     && is_single() // Checks if this is a single post
     && has_term( 'term-name or id or slug', 'my_taxonomy', $post->ID ) // Check if post has specific term
) {
    // Do something if our condition is true

Please try below code:

if(has_tag( array( 'sharp', 'mild', 'extreme' ) ) && get_post_type()=="custom-post-type"){

The array value should be the term name which is stored in taxonomy.

You can directly pass the array in has_tag() function

  • has_tag() will not work. It works for the build in taxonomy post_tag, not a custom taxonomy Jun 22 '15 at 12:23
  • Also note, there is no gas_tag() function. I have corrected that Jun 22 '15 at 12:25
  • i have write for has_tag() function not gas_tag() function.

  • Whatever. Please see the revision history if you think I'm lying. As I said, I have corrected it Jun 22 '15 at 13:14
  • please check this if(in_array('tag-name',get_the_tags()) && get_post_type()=="custom-post-type")
