Given the function $f(x)=A\sin (2x+φ)$, where $x\in R$, $A > 0$, $φ\in(0, \dfrac {π}{2})$, and $f( \dfrac {π}{12})=f( \dfrac {π}{4})= \sqrt {3}$.
(I) Find the values of $A$ and $φ$;
(II) If $f(x_{0})= \dfrac {6}{5}$, $x_{0}\in[ \dfrac {π}{4}, \dfrac {π}{2}]$, find the value of $\sin (2x_{0}- \dfrac {π}{12})$.
