Purpose

The purpose of this script is to allow users to remove tags they have applied to verses.

The code snippet you provided is a PHP script that handles the removal of a tagged verse for a specific user.

Functionality

  • The script receives two POST parameters:
    • VERSE: The SURA-VERSE of the verse being tagged.
    • TAGID: The ID of the tag being removed.
  • It starts a PHP session and regenerates the session ID for security purposes.
  • It includes necessary configuration and function files.
  • It retrieves the VERSE and TAGID parameters from the POST request.
  • It constructs an SQL query to delete the corresponding tagged verse entry in the TAGGED-VERSES table based on the provided TAGID, User ID (obtained from the session), and SURA-VERSE.
  • It executes the SQL query using db_query().
  • It calls the draw_tags_for_verse() function to update the tags displayed for the specified verse.
  • The script logs the relevant information to the error log for debugging purposes.

Additional Notes

  • The script assumes that the user is already authenticated and has a valid session.
  • The db_quote() function is used to escape user input to prevent SQL injection attacks.
  • The draw_tags_for_verse() function is assumed to be defined elsewhere and is responsible for updating the tags displayed for the given verse.
