Need Help with AppThemes API
I have a fair amount of experience of programming in PHP, but none with WordPress or ClassiPress.
I understand how the hooks with the AppThemes API are supposed to work, but I don't have a good grasp of when each event occurs. I feel if I had a better understanding of that, I would have a lot less trouble getting started writing my own plug-ins.
I would like to be able to limit ad listings to a specific geographic area, either by restricting users to certain ZIP codes or cities, or by restricting addresses to certain GPS coordinates using geolocation. I have seen a number of other posts in this forum requesting variations on this theme, but mostly without any solutions.
Surely there's a relatively straightforward way to create a plug-in that can intervene during the process of ad creation and perform additional, more detailed field validation, no?
Does anyone have enough experience with the creation of plug-ins that he or she could point me in the right direction?
