HUSKY - WooCommerce Products Filter Professional

Problem

The “SEO URL request” field in HUSKY filters <script> tags for security reasons, preventing direct insertion of JSON-LD structured data (schema markup) for Google rich results.

Solution Overview

Instead of inserting full JSON-LD code directly into the SEO text field, use schema keys in HUSKY admin and store the actual JSON-LD code in separate files or functions.php.

Method 1: Static JSON Files (Recommended for Simple Schemas)

Step 1: Create schema files folder

• Navigate to /wp-content/uploads/
• Create new folder: json-ld-schemas

Step 2: Create JSON schema files

• Create files like category1.json, products.json, etc.
• Inside each file, add pure JSON-LD code (without <script> tags):

  {
      "@context": "https://schema.org", 
      "@type": "CollectionPage", 
      "name": "Product Category", 
      "description": "Category description"
  }

Step 3: Add this code to functions.php:

add_action('init', function () {
    $url_request = WOOF_EXT::$includes['applications']['url_request'];
    remove_filter('woocommerce_after_shop_loop', array($url_request->seo, 'add_seo_text'), 99999);
    
    add_filter('woocommerce_after_shop_loop', function () use ($url_request) {
        $rule = $url_request->seo->check_search_rules();
        if (!isset($rule['text']) || !$url_request->seo->do_index()) {
            return;
        }
        
        $schema_key = apply_filters('woof_seo_text', $url_request->seo->replace_vars($rule['text'], $url_request->seo->get_current_replace_vars()));
        
        if (!empty($schema_key)) {
            $upload_dir = wp_upload_dir();
            $schemas_dir = $upload_dir['basedir'] . '/json-ld-schemas/';
            $schema_file = $schemas_dir . $schema_key . '.json';
            
            if (file_exists($schema_file)) {
                $json_content = file_get_contents($schema_file);
                echo '<div class="woof_seo_text"><script type="application/ld+json">' . $json_content . "</script></div>\r\n";
            }
        }
    }, 99999);
}, 1);

Step 4: In HUSKY admin (SEO URL request → SEO text field)

• Enter only the schema key (e.g., category1)
• Do NOT enter the full JSON-LD code

Method 2: Dynamic PHP Files (For Dynamic Schemas)

Step 1: Create PHP schema files in /wp-content/uploads/json-ld-schemas/

Example: category-dynamic.php

<?php
global $wp_query;

$term = get_queried_object();
$category_name = $term ? $term->name : 'Products';
$category_url = get_term_link($term);

$schema = array(
    '@context' => 'https://schema.org',
    '@type' => 'CollectionPage',
    'name' => $category_name,
    'url' => $category_url,
    'description' => term_description($term->term_id),
    'breadcrumb' => array(
        '@type' => 'BreadcrumbList',
        'itemListElement' => array(
            array(
                '@type' => 'ListItem',
                'position' => 1,
                'name' => 'Home',
                'item' => home_url()
            ),
            array(
                '@type' => 'ListItem',
                'position' => 2,
                'name' => $category_name,
                'item' => $category_url
            )
        )
    )
);

return $schema;

Step 2: Add this code to functions.php:

add_action('init', function () {
    $url_request = WOOF_EXT::$includes['applications']['url_request'];
    remove_filter('woocommerce_after_shop_loop', array($url_request->seo, 'add_seo_text'), 99999);
    
    add_filter('woocommerce_after_shop_loop', function () use ($url_request) {
        $rule = $url_request->seo->check_search_rules();
        if (!isset($rule['text']) || !$url_request->seo->do_index()) {
            return;
        }
        
        $schema_key = apply_filters('woof_seo_text', $url_request->seo->replace_vars($rule['text'], $url_request->seo->get_current_replace_vars()));
        
        if (!empty($schema_key)) {
            $upload_dir = wp_upload_dir();
            $schemas_dir = $upload_dir['basedir'] . '/json-ld-schemas/';
            $schema_file = $schemas_dir . $schema_key . '.php';
            
            if (file_exists($schema_file)) {
                $schema_data = include($schema_file);
                $json_output = json_encode($schema_data, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT);
                echo '<div class="woof_seo_text"><script type="application/ld+json">' . $json_output . "</script></div>\r\n";
            }
        }
    }, 99999);
}, 1);

Usage Example

In HUSKY Admin:

1. Go to “SEO URL request” settings
2. Create a rule for specific filter combination
3. In “SEO text” field, enter only: category-dynamic (or any key name)
4. Save

Result:

• The schema file /wp-content/uploads/json-ld-schemas/category-dynamic.php will be loaded
• JSON-LD will be properly rendered in the page source
• Google can read and validate the structured data

Important Notes

• Use keys only in HUSKY admin SEO text field (e.g., products, category1)
• Never paste full JSON-LD code directly into HUSKY admin
• For static schemas → use .json files
• For dynamic schemas → use .php files that return array
• Clear cache after making changes

Validation

After implementation, validate your schema:

1. Visit the filtered page on your site
2. Copy the page URL
3. Test at: https://search.google.com/test/rich-results
4. Check for errors
