Keep your database clean and free from duplicate or degraded entries with the Ajax Duplicate Alert add-on for GeoDirectory.
With the add-on activated, GeoDirectory will check new entry titles in real time against those titles already in the database. If there’s a match, the user will be alerted to the duplicate and prompted to check the existing entry before proceeding.
It’s easy to set parameters for the add-on. For each custom post type (CPT) you can specify whether the add-on should check against several fields including Title, Address, Phone or E-mail.
Check to be sure you have the following plugins installed before you get started.
