Can you help me in this?

Hi,

The code is working fine but the product pagination not working and giving 404 found error. Can you please help....

thanks

Got it working as per someone's comment add these two lines

$slug = ! empty( $vars['pagename'] ) ? $vars['pagename'] : ( ! empty( $vars['name'] ) ? $vars['name'] : ( ! empty( $vars['category_name'] ) ? $vars['category_name'] : $vars['attachment'] ) ); $slug_array = explode( '/', $slug ); // New line to be added for subcategory $slug = array_values( array_slice( $slug_array, -1 ) )[0]; // new line to be added for subcategory $exists = $wpdb->get_var( $wpdb->prepare( "SELECT t.term_id FROM $wpdb->terms t LEFT JOIN $wpdb->term_taxonomy tt ON tt.term_id = t.term_id WHERE tt.taxonomy = 'product_cat' AND t.slug = %s", array( $slug ) ) );
To make it work for subcategory (just the code above won't work for subcategory)

Does anyone know how we can use Regex
url/product-category/product-slug to url/product-slug so as to add redirects?

@gerharddt were you able to make it work with Pagination? finally, it doesn't work for me or anyone else figured out how to make it work with pagination.

I ended up just renaming it and the client was happy. Please see the function below:

// the neat way using WooCommerce filter - permalinks
function product_cat_setup($args){
$args['rewrite']['slug'] = 'shop';
return $args;
}
add_filter('woocommerce_taxonomy_args_product_cat', 'product_cat_setup');

@gerharddt ah, unfortunately, won't work for me as I need this product-category gone, but thanks.

For anyone having issues with pagination not working, use this plugin instead https://wordpress.org/plugins/woo-permalink-manager/

Using jet woo builder and/or nested categories?
Use this code:

add_filter('request', function( $vars ) {
	global $wpdb;
	if(isset($vars['jet-woo-builder']))
		return $vars;
	if(isset($vars['error'])){
		$lastVar = basename($_SERVER['REQUEST_URI']);
		$vars['attachment'] = $lastVar;
	}
	if( ! empty( $vars['pagename'] ) || ! empty( $vars['category_name'] ) || ! empty( $vars['name'] ) || !empty( $vars['attachment'] ) ) {
		$slug = ! empty( $vars['pagename'] ) ? $vars['pagename'] : ( ! empty( $vars['name'] ) ?
			$vars['name'] : ( !empty( $vars['category_name'] ) ? $vars['category_name'] : $vars['attachment'] ) );
		$_slug = explode('/',$slug);
		$slug = end($_slug);
		$exists = $wpdb->get_var( $wpdb->prepare( "SELECT t.term_id FROM $wpdb->terms t LEFT JOIN $wpdb->term_taxonomy tt ON tt.term_id = t.term_id WHERE tt.taxonomy = 'product_cat' AND t.slug = %s" ,array(
			$slug )));
		if( $exists ){
			$old_vars = $vars;
			$vars = array('product_cat' => $slug );
			if ( !empty( $old_vars['paged'] ) || !empty( $old_vars['page'] ) )
				$vars['paged'] = ! empty( $old_vars['paged'] ) ? $old_vars['paged'] : $old_vars['page'];
			if ( !empty( $old_vars['orderby'] ) )
				$vars['orderby'] = $old_vars['orderby'];
			if ( !empty( $old_vars['order'] ) )
				$vars['order'] = $old_vars['order'];
		}
	}
	return $vars;
});
