I'm having problems with my pagination. The root of the problem is that the product categories goes down 3 levels.
I used the script from the timersys gist: https://gist.github.com/timersys/78a2305d810c27efcb10ce62712d1d95
Then to accommodate the 3rd level of the categories I added the following:
add_filter('request', function( $vars ) {
global $wpdb;
if(isset($vars['error'])){
$lastVar = basename($_SERVER['REQUEST_URI']);
$vars['attachment'] = $lastVar;
}
//rest of the code
}
from here: https://wordpress.stackexchange.com/questions/258053/remove-product-category-slug-plugin-works-with-1-subcategroy-not-with-2/258085#258085
So everything is working and filtering correctly now except when I change pages on the pagination, it takes me to a single product instead of the next page.

I'm using WooCommerce and Elementor Pro. Is there any way to add specific product attributes (e.g. gross and net weight) below the Add to cart button?
It seems like an obvious thing but I haven't found options or snippets for it.
First you add attributes to product. Then you use this snippet in functions.php:
// maybe remove tab with attributes
add_filter( 'woocommerce_product_tabs', 'remove_info', 100, 1 );
function remove_info( $tabs ) {
unset($tabs['additional_information']);
return $tabs;
}
// show attributes
add_action( 'woocommerce_single_product_summary', 'summary_attributes', 35 );
function summary_attributes() {
global $product;
if ( $product->has_attributes() ) {
wc_display_product_attributes( $product );
}
}
Setting Up WooCommerce Attributes
go to Products > Attributes
Add the attribute name
Slug will automatically be created, and we can leave the rest of these options untouched.
Click “Add attribute” button and your attribute will be added.
Configure The Attributes
After creating attribute, now we can add different variation on your product. Click on the Configure Terms option.
Enter the variation
Add some short description
Click on the add new tab

In WP 5.4.2 I want to create a custom archive page for a category and all it's child categories. I am aware of the template file hierarchy:
1. category-slug.php
2. category-ID.php
3. category.php
4. archive.php
5. index.php
but if I understand correctly and if I did all the testing right, the category-slug.php, or the category-id.php scheme applies to a single category regardless of the category hierarchy.
Let's say I have following categories:
colors (id 2)
- red (id 10)
- green (id 11)
- blue (id 12)
I need a single template file for all of them. Simply creating category-colors.php or category-2.php doesn't work. It applies to the single category (colors) only. I want it to apply to all the current child categories, as well as all the child categories I add in the future. Is it possible? If so, please advice how.
There are a couple of ways to do this, but using the category_template filter to let you use a custom category template seems the most common.
The function below will let you dynamically check back through the parent levels of the current category until it finds a template called "category-[parent slug]" for the closest ancestor category or it reaches the top level - whichever is first.
Suppose you have something like:
- products
- hardware
- food
- dairy
- vegetables
On the dairy page, it will first check if you have a slug called category-dairy.php.
If you do, it will return it.
If you don't, it will look for category-food.php.
If that's not found, it will look for category-products.php.
Add this to your functions.php - this is untested by the code is well commented so you can understand how it works:
function get_template_for_category( $template ) {
if ( basename( $template ) === 'category.php' ) { // No custom template for this specific term, let's find it's parent
// get the current term, e.g. red
$term = get_queried_object();
// check for template file for the page category
$slug_template = locate_template( "category-{$term->slug}.php" );
if ( $slug_template ) return $slug_template;
// if the page category doesn't have a template, then start checking back through the parent levels to find a template for a parent slug
$term_to_check = $term;
while ( $term_to_check ->parent ) {
// get the parent of the this level's parent
$term_to_check = get_category( $term_to_check->parent );
if ( ! $term_to_check || is_wp_error( $term_to_check ) )
break; // No valid parent found
// Use locate_template to check if a template exists for this categories slug
$slug_template = locate_template( "category-{$term_to_check->slug}.php" );
// if we find a template then return it. Otherwise the loop will check for this level's parent
if ( $slug_template ) return $slug_template;
}
}
return $template;
}
add_filter( 'category_template', 'get_template_for_category' );

Make categories use parent template
I'd like to display product variations for some (not all) variable products on the shop and product-category pages based on a custom field I'm planning to add to each variable product. To keep pagination working, I can hook in to the woocommerce_product_query hook in WC_Query::product_query($q) but I can't figure out how to modify the query to give me what I'm after.
The logic I want to apply is:
//Pseudo-code
$loop = $query->get_all_products // i.e. not just for one page
foreach ( $loop as $product) {
if ($product->is_simple) {
display_simple($product)
} else {
$variations = wc_get_products($product->get_children());
foreach ($variations as $product) {
if ($product->custom_show_on_archive_pages) {
display_variation($product)
}
}
}
}
The problem with the above (apart from being pseudo-code) is that it assumes we have an array called $loop but actually we have a query object.
My ideal would be to modify the query so that it generates the results as per the pseudo-code, and then my archive-product.php template can use an if/else to display simple vs variable products.
Something like this in my functions.php:
add_action( 'woocommerce_product_query', 'show_variable_products');
function show_variable_products( $q ) {
$meta_query = $q->get('meta_query');
// Do something
$q->set('meta_query', $meta_query);
}
I'm wondering if I need to actually run multiple queries somehow:
The original query but filtered to parent products
The children of these parent products (i.e. the variations), filtered to those with custom field checked
The original query but filtered to simple products
Merge (2) and (3)
Would this be possible?
Alternatively, is there another solution (that does not involve buying a plugin)?
I want the possibility to choose between grid and list view for each Woocommerce category. I have found this plugin: https://nl.wordpress.org/plugins/woocommerce-grid-list-toggle/
However, the plugin is meant for the shopper to choose whether to display items in grid view or list view. What I truly want is the ability to assign a view for each category in the back-end.
Example:
Category A is displayed as grid
Category B is displayed as list
Breaking my head over this.
Similar to this question you need to filter template_include. You need to call your custom archive template archive-list-view.php and save it in your theme's woocommerce folder. Obviously, you can name it anything you like, you will just have to adjust the code below to match.
Folder structure:
/theme-folder/functions.php
/theme-folder/woocommerce/archive-list-view.php
On the template_include filter we will check if we are on the term archive for the nussmylch product category. If so, we'll look for and supply the new template. Otherwise, the standard template is used.
EDIT: incorrect WooCommerce function is_product_taxonomy() was used. is_product_category() is needed to check for a specific category.
add_filter( 'template_include', 'so_33615903_custom_category_template', 20 );
function so_33615903_custom_category_template( $template ) {
// check you are on the taxonomy archive for specific category
if ( is_product_category( 'nussmylch' ) ) {
$new_template = locate_template( array( 'woocommerce/archive-list-view.php' ) );
if ( '' != $new_template ) {
$template = $new_template ;
}
}
return $template;
}
Working Example
I'm using WooCommerce plugin for Wordpress. It comes with a widget called WooCommerce Product Categories which can display a drop-down of all your product categories. I have searched online and found the following code which will exclude certain categories from appearing, categories with ID 16 and 20 in this snippet:
add_filter( 'woocommerce_product_categories_widget_args', 'woo_product_cat_widget_args' );
function woo_product_cat_widget_args( $cat_args ) {
$cat_args['exclude'] = array('16','20');
return $cat_args;
}
What I need is the opposite. I want a filter/function similar to above, but which enables me to specify which categories to include - i.e. exclude everything but the IDs that I specify.
You can try this;
add_filter( 'woocommerce_product_categories_widget_args', 'woo_product_cat_widget_args' );
function woo_product_cat_widget_args( $cat_args ) {
$cat_args['include'] = array('16','20');
return $cat_args;
}
actually you can use any of these arguments that listed on this page https://codex.wordpress.org/Template_Tags/wp_list_categories
Hope that helps!
