SRP 50% from 2 tests

🔹 Tests weight: 20 | A shallow check of the single-responsibility principle; PHP files should perform no action - including output of placeholder text - and trigger no errors when accessed directly
Please take a closer look at the following
  • 3× PHP files trigger errors when accessed directly with GET requests:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function apply_filters() in wp-content/plugins/add-tag-to-woocommerce-products/wc_tag_on_products.php:12
    • > PHP Fatal error
      Uncaught Error: Call to a member function get_row() on null in wp-content/plugins/add-tag-to-woocommerce-products/admin/display_setting_page.php:6
    • > PHP Notice
      Trying to get property 'prefix' of non-object in wp-content/plugins/add-tag-to-woocommerce-products/admin/display_setting_page.php on line 5

User-side errors Passed 1 test

🔹 Test weight: 20 | This is a smoke test targeting browser errors/issues
No browser issues were found


Plugin configuration 93% from 29 tests

readme.txt 94% from 16 tests

The readme.txt file is undoubtedly the most important file in your plugin, preparing it for public listing on WordPress.org
Attributes that need to be fixed:
  • Screenshots: These screenshots do not have images: #1 (Dashboard page for settings), #2 (Dashboard page for editing a tag text and number of days), #3 (Thats how tag look on frontend end on products)
The official readme.txt is a good inspiration

add-tag-to-woocommerce-products/wc_tag_on_products.php 92% from 13 tests

The main file in "Add Custom Tags To WooCommerce Products" v. 1.0 serves as a complement to information provided in readme.txt and as the entry point to the plugin
Please take the time to fix the following:
  • Main file name: It is recommended to name the main PHP file as the plugin slug ("add-tag-to-woocommerce-products.php" instead of "wc_tag_on_products.php")
