Tagging Tools plugin for Question2Answer

This is an event plugin for popular open source Q&A platform, Question2Answer. It allows you to select 'tag synonyms' - unwanted or duplicate tags that should be changed or removed.

For example if you had websites as a tag, some users may tag a question with website instead. With this plugin you can set website to always be changed to websites when a user enters it.

Other features include min/max tag length and redirecting old tag pages to the new synonym.

Installation & Usage

  1. Download and extract the files to your Q2A plugins folder (e.g. qa-plugin/tagging-tools). Check the releases page for the latest official version.

  2. If your site uses a different language, copy qa-tt-lang-default.php to a new file with the required country code (e.g. qa-tt-lang-de.php for German) and edit the phrases for your language.

  3. Log in to your Q2A site as an Administrator and head to Admin > Plugins.

  4. Under "Tagging Tools", enter each pair of tags on a new line, separated by a comma. For example, q2a,question2answer (without quotes) means that a tag of q2a will be replaced by question2answer, while help on its own line means that tag will be removed. Save the changes and all future questions will replace your chosen tag synonyms.

  5. If you have existing mistagged questions, tick the checkbox to replace all tags in older questions with your synonyms. WARNING: if you have a lot of questions on your site, converting all the old questions will take a long time. It's recommended that you add tag synonyms a handful at a time to avoid too much overhead.

  6. The minimum/maximum length options do as the name suggests - prevent users from entering tags that are too long or too short.

  7. The new tags option limits users under a point threshold to using existing tags only. On the front-end it adds a JavaScript barrier, which for performance reasons only checks against the top tags (number as determined by the QA_DB_RETRIEVE_COMPLETE_TAGS constant) that are used for auto-complete. The server-side filter checks against all tags, i.e. if JS is turned off the user can input a tag not in the most popular but it must already exist.

  8. The redirects option will add 301 redirects from old tag pages to new tag pages. For example if you change q2a to question2answer then the page example.com/tag/q2a would now be blank, so this option will redirect the page to example.com/tag/question2answer. If you use this feature, make sure to convert all existing tag synonyms! Otherwise if you still have some questions with the old tags, those tag pages will not be viewable any more.

You can’t perform that action at this time.
