WooCommerce how to check if page is_shop() in functions.php?

4 comments

1. When placed inside a hook, is_shop will work in functions.php

   add_action( 'template_redirect', 'custom_template_redirect' );
   
   function custom_template_redirect() {
   
       if( is_shop() ) :
   
            // code logic here
   
       endif;    
   }
   

   Here is a list of all WooCommerce conditionals

2. You can write a condition into “archive-product.php” for category page like,

       $cate = get_queried_object();
       if(is_product_category()  && $cate->parent != 0 ){
   
            // Write code here
            //include sidebar here
       }
   

   By using this code this will check the page for product_category and also check for a parent.

3. call it using WordPress Hook pre get posts

   add_action('pre_get_posts','nameTheFunction');
   
   function nameTheFunction(){
   
      if(is_shop()){
   
       // your code here 
   
     }
   
   }// function end here

4. You can use function_exists

   if( function_exists("is_shop") ) {
       // call it or do something else
   }
   else {
       // load it from somewhere
   }
