A Question About Purchasing A Used Lens - Canon FD Lens to Canon EOS Rebel T3

Okay someone (not here) suggested I should purchase a Canon FD 50mm 1:1.8 lens and since I had some Amazon gift cards I thought what the hell. I can use a nice prime lens with decent bokeh. Now I find out it might not connect to my Canon EOS Rebel T3 without an adapter? Can someone out there with more knowledge help me out and clarifie this for me?

Thanks.
