I'm just seeking a place to start learning how to do this, as I haven't found anything yet aside from instructions on how to shorten links in WordPress. My goal is to create a page where visitors enter a link and we return a shortened link with tracking analytics, basically, a custom knock-off Bit.ly. I have done a lot of research but come up empty except for this question: Auto Link shorting via PHP&AJAX (bit.ly), which is unfortunately not quite what I'm looking for. This has to be done in WordPress, and I've read through dozens of WordPress forums with no luck yet. Obviously, a solution would be welcome, but I'm really just trying to find a place to start researching/learning how to do this (especially since I have no useful research yet to offer). Thanks!
