Custom Conditionals?

Hi, we currently have a plug-in called WP Triggers that is no longer being updated or supported. It does exactly what we need, which is let us put in custom conditionals. For instance we can choose “When a User Types” and then put in a list of zipcodes. If the zipcode the user types in matches, it will display one message, if it doesn’t it will display another. I am having a really really hard time finding a plugin to replace this one. I wish I could keep it, but we have to update the PHP and our current plugin is causing the PHP not to update. Is this a function you would be adding in the future?
